  • set all nested li's to be width of widest li

    - by unhitched
    hey, How do I make nested li's the same width? When I use the below code each nested li is only as wide as it's text + margin. I'd like all of the li's to be as wide as the widest li under the parent ul. eg: <ul id="menu"> <li <a href="#" title="Menu a">Menu a</a></li> <li <a href="#" title="Menu b">Menu b</a></li> <li <a href="#" title="Nested Menu">Nested Menu</a> <ul> <li <a href="#" title="Menu Item">Menu Item</li> <li <a href="#" title="Long Menu Item">Long Menu Item</a></li> <li <a href="#" title="Longer Menu Item">Longer Menu Item</a></li> </ul> </li> <li <a href="#" title="Menu z">Menu z</a></li> </ul> with css: <style type="text/css" media="all"> * { padding:0; margin:0; } body, html { width: 100%; height: 100%; } #wrapper { width: 800px; height: 100%; margin: auto; } #menu { margin: 0 0 0 8px; padding: 0; font-size: 14px; font-weight: normal; } #menu ul { list-style-type:none; list-style-position:outside; position:relative; z-index:300; height: 32px; font-weight:bold; white-space: nowrap; padding:0; } #menu a {text-decoration:none; line-height: 32px; } #menu a:hover { } #menu li { float:left; position:relative; display: inline; height: 100%; list-style-type: none; padding: 0 20px; background: #ccc; } #menu ul { position:absolute; display:none; left:0px; background: #BDCCD4; width:100%; } #menu ul a, #menu li a { display: block; } #menu li ul { background: #BDCCD4; display:block; } #menu li ul a { font-weight: normal; height:auto; float:left; } #menu ul ul { padding: 0 9px; display:block; } #menu li ul li { padding: 0 9px; background: #BDCCD4; } #menu li:hover { background: #ddd; height: 32px; } #menu li li:hover, #menu li li li:hover { background: #ddd; height: 32px; } #menu li a:link, #menu li a:visited { text-decoration: none; color: #003E7E; margin: auto; }

  • xpath 2.0 query - how to test for the first occurence of an element in a xml document

    - by Mike
    I have the following xsl template: <xsl:template match="para"> <fo:block xsl:use-attribute-sets="paragraph.para"> <!-- if first para in document --> <!--<xsl:if test="//para[1] intersect .">--> <xsl:if test="//para[1] intersect ."> <xsl:attribute name="space-after">10pt</xsl:attribute> <xsl:attribute name="background-color">yellow</xsl:attribute> </xsl:if> <xsl:choose> <xsl:when test="preceding-sibling::*[1][self::title]"> <xsl:attribute name="text-indent">0em</xsl:attribute> </xsl:when> <xsl:when test="parent::item"> <xsl:attribute name="text-indent">0em</xsl:attribute> </xsl:when> <xsl:otherwise> <xsl:attribute name="text-indent">1em</xsl:attribute> </xsl:otherwise> </xsl:choose> <xsl:apply-templates/> </fo:block> </xsl:template> The problem I am having is selecting the very first para node in the document from the following xml: <document> <section> <paragraph> <para>Para Text 1*#</para> <para>Para Text 2</para> </paragraph> </section> <paragraph> <para>Para Text 3*</para> <para>Para Text 4</para> <para>Para Text 5</para> <sub-paragraph> <para>Para Text 6*</para> <para>Para Text 7</para> </sub-paragraph> </paragraph> <appendix> <paragraph> <para>Para Text 8*</para> </paragraph> <paragraph> <para>Para Text 9</para> </paragraph> </appendix> </document> the xpath I am currently using is "//para[1] intersect ." which is selecting the first para for each group of para (denoted with a * in XML sample). Any ideas on how I can just select the first occurance of para within document (denoted with a #)?

  • Asp.Net Export to Excel - Japanese Characters

    - by Kalyan
    I am currently using Visual Studio 2008 for my ASP .NET application. I am trying to Export some reports with Japanese Characters to Excel via the Response object. When I try to Export, all the Japanese characters looks garbled. It works fine with Chinese Characters. Here is what I tried: I tried Installed Japanese Language Pack / Encoding to UTF-8 / UTF-7 / Shift-JIS / Globalization (Web.Config) .. but no luck. Any Ideas how this can be fixed ? Thanks !! string attachment = "attachment; filename=PerksPlusReport.xls"; //Response.Clear(); Response.ClearContent(); Response.ClearHeaders(); Response.AddHeader("content-disposition", attachment); //Response.Charset = "UTF-8"; //Response.Charset = "UTF-7"; //Response.Charset = "Shift_JIS"; Response.ContentType = "application/vnd.ms-excel"; StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); // Create a form to contain the grid HtmlForm frm = new HtmlForm(); ReportGridView.Parent.Controls.Add(frm); frm.Attributes["runat"] = "server"; GridView GridView2 = new GridView(); ReportView reportDetails = GetReportDetails(); GridView2.DataSource = GetReportResults(this.ReportId.Value, reportDetails.Sql); GridView2.DataBind(); PrepareGridViewForExport(GridView2); frm.Controls.Add(GridView2); frm.RenderControl(htw); string fileContents = sw.ToString(); int startSpot = fileContents.IndexOf("<table"); fileContents = fileContents.Substring(startSpot); int endSpot = fileContents.IndexOf("</table>"); fileContents = fileContents.Substring(0, endSpot + 8); try { // Replace all &lt; and &gt; with < and > fileContents = fileContents.Replace("&lt;", "<"); fileContents = fileContents.Replace("&gt;", ">"); fileContents = fileContents.Replace("€", "&euro;"); string RegularExpression = @"<a[^>]*>([^<]*)</a>"; Regex regex = new Regex(RegularExpression); //If match found .. uses the delegate function to replace the whole content with the filtered values if (regex.IsMatch(fileContents)) { regex.Replace(fileContents, delegate (Match m){return fileContents.Replace(m.Captures[0].Value, m.Groups[1].Value);}); } } catch (Exception ex2) { Response.Write(ex2.ToString()); } Response.Write(fileContents); Response.End();

  • Two UIViews, one UIViewController (in one UINavigationController)

    - by jdandrea
    Given an iPhone app with a UITableViewController pushed onto a UINavigationController, I would like to add a right bar button item to toggle between the table view and an "alternate" view of the same data. Let's also say that this other view uses the same data but is not a UITableView. Now, I know variations on this question already exist on Stack Overflow. However, in this case, that alternate view would not be pushed onto the UINavigationController. It would be visually akin to flipping the current UIViewController's table view over and revealing the other view, then being able to flip back. In other words, it's intended to take up a single spot in the UINavigationController hierarchy. Moreover, whatever selection you ultimately make from within either view will push a common UIViewController onto the UINavigationController stack. Still more info: We don't want to use a separate UINavigationController just to handle this pair of views, and we don't want to split these apart via a UITabBarController either. Visually and contextually, the UX is meant to show two sides of the same coin. It's just that those two sides happen to involve their own View Controllers in normal practice. Now … it turns out I have already gone and quickly set this up to see how it might work! However, upon stepping back to examine it, I get the distinct impression that I went about it in a rather non-MVC way, which of course concerns me a bit. Here's what I did at a high level. Right now, I have a UIViewController (not a UITableViewController) that handles all commonalities between the two views, such as fetching the raw data. I also have two NIBs, one for each view, and two UIView objects to go along with them. (One of them is a UITableView, which is a kind of UIView.) I switch between the views using animation (easy enough). Also, in an effort to keep things encapsulated, the now-split-apart UITableView (not the UIViewController!) acts as its own delegate and data source, fetching data from the VC. The VC is set up as a weak, non-retained object in the table view. In parallel, the alternate view gets at the raw data from the VC in the exact same way. So, there are a few things that smell funny here. The weak linking from child to parent, while polite, seems like it might be wrong. Making a UITableView the table's data source and delegate also seems odd to me, thinking that a view controller is where you want to put that per Apple's MVC diagrams. As it stands now, it would appear as if the view knows about the model, which isn't good. Loading up both views in advance also seems odd, because lazy loading is no longer in effect. Losing the benefits of a UITableViewController (like auto-scrolling to cells with text fields) is also a bit frustrating, and I'd rather not reinvent the wheel to work around that as well. Given all of the above, and given we want that "flip effect" in the context of a single spot on a single UINavigationController, and given that both views are two sides of the same coin, is there a better, more obvious way to design this that I'm just happening to miss completely? Clues appreciated!

  • Implementation question involving implementing an interface

    - by Vivin Paliath
    I'm writing a set of collection classes for different types of Trees. I'm doing this as a learning exercise and I'm also hoping it turns out to be something useful. I really want to do this the right way and so I've been reading Effective Java and I've also been looking at the way Joshua Bloch implemented the collection classes by looking at the source. I seem to have a fair idea of what is being done, but I still have a few things to sort out. I have a Node<T> interface and an AbstractNode<T> class that implements the Node interface. I then created a GenericNode<T> (a node that can have 0 to n children, and that is part of an n-ary tree) class that extends AbstractNode<T> and implements Node<T>. This part was easy. Next, I created a Tree<T> interface and an AbstractTree<T> class that implements the Tree<T> interface. After that, I started writing a GenericTree<T> class that extends AbstractTree<T> and implements Tree<T>. This is where I started having problems. As far as the design is concerned, a GenericTree<T> can only consist of nodes of type GenericTreeNode<T>. This includes the root. In my Tree<T> interface I have: public interface Tree<T> { void setRoot(Node<T> root); Node<T> getRoot(); List<Node<T>> postOrder(); ... rest omitted ... } And, AbstractTree<T> implements this interface: public abstract class AbstractTree<T> implements Tree<T> { protected Node<T> root; protected AbstractTree() { } protected AbstractTree(Node<T> root) { this.root = root; } public void setRoot(Node<T> root) { this.root = root; } public Node<T> getRoot() { return this.root; } ... rest omitted ... } In GenericTree<T>, I can have: public GenericTree(Node<T> root) { super(root); } But what this means is that you can create a generic tree using any subtype of Node<T>. You can also set the root of a tree to any subtype of Node<T>. I want to be able to restrict the type of the node to the type of the tree that it can represent. To fix this, I can do this: public GenericTree(GenericNode<T> root) { super(root); } However, setRoot still accepts a parameter of type Node<T>. Which means a user can still create a tree with the wrong type of root node. How do I enforce this constraint? The only way I can think of doing is either: Do an instanceof which limits the check to runtime. I'm not a huge fan of this. Remove setRoot from the interface and have the base class implement this method. This means that it is not part of the contract and anyone who wants to make a new type of tree needs to remember to implement this method. Is there a better way? The second question I have concerns the return type of postOrder which is List<Node<T>>. This means that if a user is operating on a GenericTree<T> object and calls postOrder, he or she receives a list that consists of Node<T> objects. This means when iterating through (using a foreach construct) they would have perform an explicit cast to GenericNode<T> if they want to use methods that are only defined in that class. I don't like having to place this burden on the user. What are my options in this case? I can only think of removing the method from the interface and have the subclass implement this method making sure that it returns a list of appropriate subtype of Node<T>. However, this once again removes it from the contract and it's anyone who wants to create a new type of tree has to remember to implement this method. Is there a better way?

I offer up for sacrifice my Frankenstein's monster. Tell me how ugly it is. Tell me I should download forbidden 3rd party software.

The munge-fest frantically escalates into some xargs du recycling where -x/-d is actually useful, and a final, gratuitous egrep spits out a list of directories that almost feels like an accomplishment: Linux: 54M etc/gconf 61M opt/quest 77M opt 118M usr/ ##===\ 149M etc 154M root 303M lib/modules 313M usr/java ##====\ 331M lib 357M usr/lib64 ##=====\ 433M usr/lib ##========\ 1.1G usr/share ##=======\ 3.2G usr/local ##========\ 5.4G usr ##<=============Ascending order to parent 94M app/SIP ##<==\ 94M app ##<=======Were reported as 7gb and then corrected by second du with -x.

Edit: Are there any bash one-liner heroes out there than can turn my bloated abomination into divine intervention, or at least something resembling gingerly copypasta?

  • linux thread synchronization

    - by johnnycrash
    I am new to linux and linux threads. I have spent some time googling to try to understand the differences between all the functions available for thread synchronization. I still have some questions. I have found all of these different types of synchronizations, each with a number of functions for locking, unlocking, testing the lock, etc. gcc atomic operations futexes mutexes spinlocks seqlocks rculocks conditions semaphores My current (but probably flawed) understanding is this: semaphores are process wide, involve the filesystem (virtually I assume), and are probably the slowest. Futexes might be the base locking mechanism used by mutexes, spinlocks, seqlocks, and rculocks. Futexes might be faster than the locking mechanisms that are based on them. Spinlocks dont block and thus avoid context swtiches. However they avoid the context switch at the expense of consuming all the cycles on a CPU until the lock is released (spinning). They should only should be used on multi processor systems for obvious reasons. Never sleep in a spinlock. The seq lock just tells you when you finished your work if a writer changed the data the work was based on. You have to go back and repeat the work in this case. Atomic operations are the fastest synch call, and probably are used in all the above locking mechanisms. You do not want to use atomic operations on all the fields in your shared data. You want to use a lock (mutex, futex, spin, seq, rcu) or a single atomic opertation on a lock flag when you are accessing multiple data fields. My questions go like this: Am I right so far with my assumptions? Does anyone know the cpu cycle cost of the various options? I am adding parallelism to the app so we can get better wall time response at the expense of running fewer app instances per box. Performances is the utmost consideration. I don't want to consume cpu with context switching, spinning, or lots of extra cpu cycles to read and write shared memory. I am absolutely concerned with number of cpu cycles consumed. Which (if any) of the locks prevent interruption of a thread by the scheduler or interrupt...or am I just an idiot and all synchonization mechanisms do this. What kinds of interruption are prevented? Can I block all threads or threads just on the locking thread's CPU? This question stems from my fear of interrupting a thread holding a lock for a very commonly used function. I expect that the scheduler might schedule any number of other workers who will likely run into this function and then block because it was locked. A lot of context switching would be wasted until the thread with the lock gets rescheduled and finishes. I can re-write this function to minimize lock time, but still it is so commonly called I would like to use a lock that prevents interruption...across all processors. I am writing user code...so I get software interrupts, not hardware ones...right? I should stay away from any functions (spin/seq locks) that have the word "irq" in them. Which locks are for writing kernel or driver code and which are meant for user mode? Does anyone think using an atomic operation to have multiple threads move through a linked list is nuts? I am thinking to atomicly change the current item pointer to the next item in the list. If the attempt works, then the thread can safely use the data the current item pointed to before it was moved. Other threads would now be moved along the list. futexes? Any reason to use them instead of mutexes? Is there a better way than using a condition to sleep a thread when there is no work? When using gcc atomic ops, specifically the test_and_set, can I get a performance increase by doing a non atomic test first and then using test_and_set to confirm? *I know this will be case specific, so here is the case. There is a large collection of work items, say thousands. Each work item has a flag that is initialized to 0. When a thread has exclusive access to the work item, the flag will be one. There will be lots of worker threads. Any time a thread is looking for work, they can non atomicly test for 1. If they read a 1, we know for certain that the work is unavailable. If they read a zero, they need to perform the atomic test_and_set to confirm. So if the atomic test_and_set is 500 cpu cycles because it is disabling pipelining, causes cpu's to communicate and L2 caches to flush/fill .... and a simple test is 1 cycle .... then as long as I had a better ratio of 500 to 1 when it came to stumbling upon already completed work items....this would be a win.* I hope to use mutexes or spinlocks to sparilngly protect sections of code that I want only one thread on the SYSTEM (not jsut the CPU) to access at a time. I hope to sparingly use gcc atomic ops to select work and minimize use of mutexes and spinlocks. For instance: a flag in a work item can be checked to see if a thread has worked it (0=no, 1=yes or in progress). A simple test_and_set tells the thread if it has work or needs to move on. I hope to use conditions to wake up threads when there is work. Thanks!

  • Forcing a transaction to rollback on validation errors in Seam

    - by Chris Williams
    Quick version: We're looking for a way to force a transaction to rollback when specific situations occur during the execution of a method on a backing bean but we'd like the rollback to happen without having to show the user a generic 500 error page. Instead, we'd like the user to see the form she just submitted and a FacesMessage that indicates what the problem was. Long version: We've got a few backing beans that use components to perform a few related operations in the database (using JPA/Hibernate). During the process, an error can occur after some of the database operations have happened. This could be for a few different reasons but for this question, let's assume there's been a validation error that is detected after some DB writes have happened that weren't detectible before the writes occurred. When this happens, we'd like to make sure all of the db changes up to this point will be rolled back. Seam can deal with this because if you throw a RuntimeException out of the current FacesRequest, Seam will rollback the current transaction. The problem with this is that the user is shown a generic error page. In our case, we'd actually like the user to be shown the page she was on with a descriptive message about what went wrong, and have the opportunity to correct the bad input that caused the problem. The solution we've come up with is to throw an Exception from the component that discovers the validation problem with the annotation: @ApplicationException( rollback = true ) Then our backing bean can catch this exception, assume the component that threw it has published the appropriate FacesMessage, and simply return null to take the user back to the input page with the error displayed. The ApplicationException annotation tells Seam to rollback the transaction and we're not showing the user a generic error page. This worked well for the first place we used it that happened to only be doing inserts. The second place we tried to use it, we have to delete something during the process. In this second case, everything works if there's no validation error. If a validation error does happen, the rollback Exception is thrown and the transaction is marked for rollback. Even if no database modifications have happened to be rolled back, when the user fixes the bad data and re-submits the page, we're getting: java.lang.IllegalArgumentException: Removing a detached instance The detached instance is lazily loaded from another object (there's a many to one relationship). That parent object is loaded when the backing bean is instantiated. Because the transaction was rolled back after the validation error, the object is now detached. Our next step was to change this page from conversation scope to page scope. When we did this, Seam can't even render the page after the validation error because our page has to hit the DB to render and the transaction has been marked for rollback. So my question is: how are other people dealing with handling errors cleanly and properly managing transactions at the same time? Better yet, I'd love to be able to use everything we have now if someone can spot something I'm doing wrong that would be relatively easy to fix. I've read the Seam Framework article on Unified error page and exception handling but this is geared more towards more generic errors your application might encounter.

  • Cakephp - Banner Problem

    - by Joe Elliott
    Hi guys I have a banner rotator on my main page and it was working but it has stopped. All I have done before it stopped was modified some of the db fields. I added to fields position and company and deleted the field 'description.' It was a friend of a friend that made this part of the site for me while i was on holiday so i dont know which files i should show you cos dont know exactly what hes done but im guessing the following ones are the ones you need. banner_view <div id="banner"> <?php if(!empty($banners) && ($banners['Banner']['position']=='Top')){ foreach($banners as $banner){ ?> <a href="<?php echo $banner['Banner']['url']; ?>"><img src="<?php echo $banner['Banner']['path']; ?>" alt="<?php echo $banner['Banner']['company']; ?>" /></a> <?php } } ?> </div> banner_controller <?php class BannersController extends AppController { var $name = 'Banners'; var $helpers = array('Html', 'Form', 'Ajax','Javascript'); var $layout = 'ajax'; var $components = array('Session', 'Cookie'); function beforeFilter() { parent::beforeFilter(); $this->Auth->allow('index','featrot'); if(strpos($this->here, 'admin')) { $this->layout = 'admin'; } } function index() { Configure::write('debug',0); $this->Banner->recursive = 0; $this->paginate['Banner']; $banners = $this->paginate(); if($banners) { $this->set('banners', $banners); } } function featrot() { Configure::write('debug',0); $this->Banner->recursive = 0; $this->paginate['Banner']; $banners = $this->paginate(); if($banners) { $this->set('banners', $banners); } } function admin_edit(){ $this->pageTitle='Admin section - .: Banners Edit:.'; $banners = $this->Banner->find('first'); $id = $banners['Banner']['id']; if (!empty($this->data)) { $this->Banner->id = $id; if ($this->Banner->save($this->data)) { $this->Session->setFlash(__('The Banner has been updated', true)); } else { $this->Session->setFlash(__('The Banner could not update.

  • Update to Easy Slider 1.7 made all my JQuery code stop working.

    - by Anders H
    I'm pretty novice as a JQuery user goes. I've got some experience implementing different plugins but would be lost trying to customize my own. I can't share the exact site details with you due to a NDA, so I hope someone can give me a little help. I've got a project due today (Just HTML/CSS/JQuery). It has a lightbox, show/hide login menu and a slider is Easy Slider 1.5. Everything was working together, until I attempted to update to Easy Slider 1.7 (see link on same page, I'm too new to post more than 1 link). When I did so, JQuery stopped working for all the plugins. I've attempted to revert back to the original state, by undoing my work (didn't do much), ad JQuery remains broken. Firebug Error Console shared no errors. I can't find anything in the code no matter how hard I look at it. Can anyone help me troubleshoot this JQuery problem? Delivery is supposed to be tonight for the project.

  • How to remove a model object from an EMF model and its GEF Editor via Adapter

    - by s.d
    This question is principally a follow-up to my question about EMF listening mechanisms. So, I have a third-party EMF model (uneditable) which is based on a generic graph model. The structure is as follows: Project | ItemGraph | Item | Document | DocumentGraph / | \ Tokens Nodes Relations(Edges) I have a GEF editor which works on the DocumentGraph (i.e., not the root object, perhaps this is a problem?): getGraphicalViewer().setContents(documentGraph). THe editor has the following edit part structure: DocumentGraphEP / \ Primary Connection LayerEP LayerEP / \ | TokenEP NodeEP RelationEP PrimaryLayerEP and ConnectionLayerEP both have simple Strings as model, which are not represented in the EMF (domain) model. They are simply used to add a primary (i.e., node) layer, and a connection layer (with ShortestPathConnectionRouter) to the editor. Problem: I am trying to get myself into the workings of EMF adapters, and have tried to make use of the available tutorials, mainly the EMF-GEF Eclipse tutorial, vainolo's blog, and vogella's tutorial. I thought I'd start with an easy thing, so tried to remove a node from the graph and see if I get it to work. Which I didn't, and I don't see where the problem is. I can select a node, and have the generic delete Action in my toolbar, but when I click it, nothing happens. Here is the respective source code for the different responsible parts. Please be so kind to point me to any errors (of thinking, coding errors, whathaveyou) you can find. NodeEditPart public class NodeEditPart extends AbstractGraphicalEditPart implements Adapter { protected IFigure createFigure() { return new NodeFigure(); } protected void createEditPolicies() { .... installEditPolicy(EditPolicy.COMPONENT_ROLE, new NodeComponentEditPolicy()); } protected void refreshVisuals() { NodeFigure figure = (NodeFigure) getFigure(); SNode model = (SNode) getModel(); PrimaryLayerEditPart parent = (PrimaryLayerEditPart) getParent(); // Set text figure.getLabel().setText(model.getSName()); .... } public void activate() { if (isActive()) return; // start listening for changes in the model ((Notifier)getModel()).eAdapters().add(this); super.activate(); } public void deactivate() { if (!isActive()) return; // stop listening for changes in the model ((Notifier)getModel()).eAdapters().remove(this); super.deactivate(); } private Notifier getSDocumentGraph() { return ((SNode)getModel()).getSDocumentGraph(); } @Override public void notifyChanged(Notification notification) { int type = notification.getEventType(); switch( type ) { case Notification.ADD: case Notification.ADD_MANY: case Notification.REMOVE: case Notification.REMOVE_MANY: refreshChildren(); break; case Notification.SET: refreshVisuals(); break; } } @Override public Notifier getTarget() { return target; } @Override public void setTarget(Notifier newTarget) { this.target = newTarget; } @Override public boolean isAdapterForType(Object type) { return type.equals(getModel().getClass()); } } NodeComponentEditPolicy public class NodeComponentEditPolicy extends ComponentEditPolicy { public NodeComponentEditPolicy() { super(); } protected Command createDeleteCommand(GroupRequest deleteRequest) { DeleteNodeCommand cmd = new DeleteNodeCommand(); cmd.setSNode((SNode) getHost().getModel()); return cmd; } } DeleteNodeCommand public class DeleteNodeCommand extends Command { private SNode node; private SDocumentGraph graph; @Override public void execute() { node.setSDocumentGraph(null); } @Override public void undo() { node.setSDocumentGraph(graph); } public void setSNode(SNode node) { this.node = node; this.graph = node.getSDocumentGraph(); } } All seems to work fine: When a node is selected in the editor, the delete symbol is activated in the toolbar, but when it is clicked, nothing happens in the editor. I'd be very thankful for any pointers :).

  • How do I use constructor dependency injection to supply Models from a collection to their ViewModels

    - by GraemeF
    I'm using constructor dependency injection in my WPF application and I keep running into the following pattern, so would like to get other people's opinion on it and hear about alternative solutions. The goal is to wire up a hierarchy of ViewModels to a similar hierarchy of Models, so that the responsibility for presenting the information in each model lies with its own ViewModel implementation. (The pattern also crops up under other circumstances but MVVM should make for a good example.) Here's a simplified example. Given that I have a model that has a collection of further models: public interface IPerson { IEnumerable<IAddress> Addresses { get; } } public interface IAddress { } I would like to mirror this hierarchy in the ViewModels so that I can bind a ListBox (or whatever) to a collection in the Person ViewModel: public interface IPersonViewModel { ObservableCollection<IAddressViewModel> Addresses { get; } void Initialize(); } public interface IAddressViewModel { } The child ViewModel needs to present the information from the child Model, so it's injected via the constructor: public class AddressViewModel : IAddressViewModel { private readonly IAddress _address; public AddressViewModel(IAddress address) { _address = address; } } The question is, what is the best way to supply the child Model to the corresponding child ViewModel? The example is trivial, but in a typical real case the ViewModels have more dependencies - each of which has its own dependencies (and so on). I'm using Unity 1.2 (although I think the question is relevant across the other IoC containers), and I am using Caliburn's view strategies to automatically find and wire up the appropriate View to a ViewModel. Here is my current solution: The parent ViewModel needs to create a child ViewModel for each child Model, so it has a factory method added to its constructor which it uses during initialization: public class PersonViewModel : IPersonViewModel { private readonly Func<IAddress, IAddressViewModel> _addressViewModelFactory; private readonly IPerson _person; public PersonViewModel(IPerson person, Func<IAddress, IAddressViewModel> addressViewModelFactory) { _addressViewModelFactory = addressViewModelFactory; _person = person; Addresses = new ObservableCollection<IAddressViewModel>(); } public ObservableCollection<IAddressViewModel> Addresses { get; private set; } public void Initialize() { foreach (IAddress address in _person.Addresses) Addresses.Add(_addressViewModelFactory(address)); } } A factory method that satisfies the Func<IAddress, IAddressViewModel> interface is registered with the main UnityContainer. The factory method uses a child container to register the IAddress dependency that is required by the ViewModel and then resolves the child ViewModel: public class Factory { private readonly IUnityContainer _container; public Factory(IUnityContainer container) { _container = container; } public void RegisterStuff() { _container.RegisterInstance<Func<IAddress, IAddressViewModel>>(CreateAddressViewModel); } private IAddressViewModel CreateAddressViewModel(IAddress model) { IUnityContainer childContainer = _container.CreateChildContainer(); childContainer.RegisterInstance(model); return childContainer.Resolve<IAddressViewModel>(); } } Now, when the PersonViewModel is initialized, it loops through each Address in the Model and calls CreateAddressViewModel() (which was injected via the Func<IAddress, IAddressViewModel> argument). CreateAddressViewModel() creates a temporary child container and registers the IAddress model so that when it resolves the IAddressViewModel from the child container the AddressViewModel gets the correct instance injected via its constructor. This seems to be a good solution to me as the dependencies of the ViewModels are very clear and they are easily testable and unaware of the IoC container. On the other hand, performance is OK but not great as a lot of temporary child containers can be created. Also I end up with a lot of very similar factory methods. Is this the best way to inject the child Models into the child ViewModels with Unity? Is there a better (or faster) way to do it in other IoC containers, e.g. Autofac? How would this problem be tackled with MEF, given that it is not a traditional IoC container but is still used to compose objects?

  • ssh login fails for user with empty password

    - by Reid
    How do you enable ssh login on OS X 10.8 (Mountain Lion) for a user with an empty password? I've seen others asking this question, and like me it's for the same reason: a parent who can't deal with passwords. So "set a password" is not an option. I found references to adding "nullok" to various PAM config files. Didn't work. Found sshd config "PermitEmptyPasswords yes". Didn't work. I've done a diff on "ssh -vvv" between a successful ssh with a password-enabled account and the one with no password. 54,55c54,55 < debug2: dh_gen_key: priv key bits set: 133/256 < debug2: bits set: 533/1024 --- > debug2: dh_gen_key: priv key bits set: 140/256 > debug2: bits set: 508/1024 67c67 < debug2: bits set: 509/1024 --- > debug2: bits set: 516/1024 79c79 < debug2: key: /Users/rae/.ssh/rae (0x7f9a0241e2c0) --- > debug2: key: /Users/rae/.ssh/rae (0x7f81e0c1e2c0) 90,116c90,224 < debug1: Authentications that can continue: publickey,keyboard-interactive < debug2: we did not send a packet, disable method < debug3: authmethod_lookup keyboard-interactive < debug3: remaining preferred: password < debug3: authmethod_is_enabled keyboard-interactive < debug1: Next authentication method: keyboard-interactive < debug2: userauth_kbdint < debug2: we sent a keyboard-interactive packet, wait for reply < debug2: input_userauth_info_req < debug2: input_userauth_info_req: num_prompts 1 < debug3: packet_send2: adding 32 (len 14 padlen 18 extra_pad 64) < debug1: Authentications that can continue: publickey,keyboard-interactive < debug2: userauth_kbdint < debug2: we sent a keyboard-interactive packet, wait for reply < debug2: input_userauth_info_req < debug2: input_userauth_info_req: num_prompts 1 < debug3: packet_send2: adding 32 (len 14 padlen 18 extra_pad 64) < debug1: Authentications that can continue: publickey,keyboard-interactive < debug2: userauth_kbdint < debug2: we sent a keyboard-interactive packet, wait for reply < debug2: input_userauth_info_req < debug2: input_userauth_info_req: num_prompts 1 < debug3: packet_send2: adding 32 (len 14 padlen 18 extra_pad 64) < debug1: Authentications that can continue: publickey,keyboard-interactive < debug2: we did not send a packet, disable method < debug1: No more authentication methods to try. < Permission denied (publickey,keyboard-interactive). --- > debug1: Server accepts key: pkalg ssh-dss blen 433 > debug2: input_userauth_pk_ok: fp 6e:02:20:63:48:6a:08:99:b8:5f:12:d8:d5:3d:e1:fb > debug3: sign_and_send_pubkey: DSA 6e:02:20:63:48:6a:08:99:b8:5f:12:d8:d5:3d:e1:fb > debug1: read PEM private key done: type DSA > debug1: Authentication succeeded (publickey). > Authenticated to cme-mini.local ([192.168.1.5]:22). > debug2: fd 7 setting O_NONBLOCK > debug3: fd 8 is O_NONBLOCK > debug1: channel 0: new [client-session] > debug3: ssh_session2_open: channel_new: 0 > debug2: channel 0: send open > debug1: Requesting [email protected] > debug1: Entering interactive session. > debug2: callback start > debug2: client_session2_setup: id 0 > debug2: fd 5 setting TCP_NODELAY > debug2: channel 0: request pty-req confirm 1 > debug1: Sending environment.

  • WPF Issues with Control Layout

    - by Brett Powell
    I am making an application that connects to our billing software using its API, and I am running into a few issues getting the layout working properly. I want to make it so that when one of the expanders is minimized, the other window fills the gap, and when it is expanded again the other expander goes back to where it was. Right now when the arrow is clicked on one, there is just an empty gap. I used a DockPanel as the parent which I assumed would automatically do this, but it isn't working. Second question, is there a way to make these areas resizable? I don't want to try and get too frisky with allowing the user to undock the menus (don't even know if that is possible with just straight WPF) but it would be nice if they could change the width/height of them. Also, just a newbie question to C#, but what is the equivalent of a C++ header file? It looks like you just use .cs files, but I am not sure. I want to extract all of my functions that pull the data from the billing software and put them into a different file to clean up the code. Here is my XAML... <Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Billing Management" Height="550" Width="754" xmlns:shared="http://schemas.actiprosoftware.com/winfx/xaml/shared" WindowStartupLocation="CenterScreen" WindowStyle="ThreeDBorderWindow"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="22" /> <RowDefinition /> </Grid.RowDefinitions> <Menu Height="22" Name="menu1" Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Top" HorizontalContentAlignment="Left" IsEnabled="True" IsMainMenu="True"> <MenuItem Header="_File"> <MenuItem Header="_Open" /> <MenuItem Header="_Close" /> <Separator/> <MenuItem Header="_Exit" /> </MenuItem> </Menu> <TabControl Name="tabControl1" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" BorderThickness="1" Padding="0" TabStripPlacement="Bottom" UseLayoutRounding="False" FlowDirection="LeftToRight" Grid.Row="1"> <TabItem Header="Main" Name="tabItem1" Margin="0"> <DockPanel Name="dockPanel1" LastChildFill="True"> <ListBox Height="100" Name="listBox3" DockPanel.Dock="Top" /> <ListBox Name="listBox4" Width="200" DockPanel.Dock="Right" /> <DockPanel Height="Auto" Name="dockPanel2" Width="Auto" VerticalAlignment="Stretch" LastChildFill="True"> <shared:AnimatedExpander Header="Staff Online" Width="200" Name="expanderStaffOnline" IsExpanded="True" Height="194" BorderThickness="0" DockPanel.Dock="Top" VerticalContentAlignment="Stretch"> <ListBox Name="listboxStaffOnline" Width="Auto" Height="Auto" Margin="0" VerticalAlignment="Stretch" Loaded="listboxStaffOnline_Loaded" /> </shared:AnimatedExpander> <shared:AnimatedExpander Header="Test Menu 2" Height="Auto" Name="animatedExpander1" BorderThickness="1" Margin="0,0,0,0" IsExpanded="True" VerticalContentAlignment="Stretch"> <ListBox Height="Auto" HorizontalAlignment="Stretch" Name="listBox6" VerticalAlignment="Stretch" Margin="0" BorderThickness="1" /> </shared:AnimatedExpander> </DockPanel> <ListBox Height="100" Name="listboxAdminLogs" DockPanel.Dock="Bottom" Loaded="listboxAdminLogs_Loaded" /> <ListBox Name="listBox5" /> </DockPanel> </TabItem> <TabItem Header="Support" Name="tabItem2" Margin="0"> </TabItem> <TabItem Header="Clients" /> <TabItem Header="Billing" /> <TabItem Header="Orders" /> </TabControl> </Grid> </Window>

  • Deleting unreferenced child records with nhibernate

    - by Chev
    Hi There I am working on a mvc app using nhibernate as the orm (ncommon framework) I have parent/child entities: Product, Vendor & ProductVendors and a one to many relationship between them with Product having a ProductVendors collection Product.ProductVendors. I currently am retrieving a Product object and eager loading the children and sending these down the wire to my asp.net mvc client. A user will then modify the list of Vendors and post the updated Product back. I am using a custom model binder to generate the modified Product entity. I am able to update the Product fine and insert new ProductVendors. My problem is that dereferenced ProductVendors are not cascade deleted when specifying Product.ProductVendors.Clear() and calling _productRepository.Save(product). The problem seems to be with attaching the detached instance. Here are my mapping files: Product <?xml version="1.0" encoding="utf-8" ?> <id name="Id"> <generator class="guid.comb" /> </id> <version name="LastModified" unsaved-value="0" column="LastModified" /> <property name="Name" type="String" length="250" /> ProductVendors <?xml version="1.0" encoding="utf-8" ?> <id name="Id"> <generator class="guid.comb" /> </id> <version name="LastModified" unsaved-value="0" column="LastModified" /> <property name="Price" /> <many-to-one name="Product" class="Product" column="ProductId" lazy="false" not-null="true" /> <many-to-one name="Vendor" class="Vendor" column="VendorId" lazy="false" not-null="true" /> Custom Model Binder: using System; using Test.Web.Mvc; using Test.Domain; namespace Spoked.MVC { public class ProductUpdateModelBinder : DefaultModelBinder { private readonly ProductSystem ProductSystem; public ProductUpdateModelBinder(ProductSystem productSystem) { ProductSystem = productSystem; } protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) { var product = bindingContext.Model as Product; if (product != null) { product.Category = ProductSystem.GetCategory(new Guid(bindingContext.ValueProvider["Category"].AttemptedValue)); product.Brand = ProductSystem.GetBrand(new Guid(bindingContext.ValueProvider["Brand"].AttemptedValue)); product.ProductVendors.Clear(); if (bindingContext.ValueProvider["ProductVendors"] != null) { string[] productVendorIds = bindingContext.ValueProvider["ProductVendors"].AttemptedValue.Split(','); foreach (string id in productVendorIds) { product.AddProductVendor(ProductSystem.GetVendor(new Guid(id)), 90m); } } } } } } Controller: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Update(Product product) { using (var scope = new UnitOfWorkScope()) { //product.ProductVendors.Clear(); _productRepository.Save(product); scope.Commit(); } using (new UnitOfWorkScope()) { IList<Vendor> availableVendors = _productSystem.GetAvailableVendors(product); productDetailEditViewModel = new ProductDetailEditViewModel(product, _categoryRepository.Select(x => x).ToList(), _brandRepository.Select(x => x).ToList(), availableVendors); } return RedirectToAction("Edit", "Products", new {id = product.Id.ToString()}); } The following test does pass though: [Test] [NUnit.Framework.Category("ProductTests")] public void Can_Delete_Product_Vendors_By_Dereferencing() { Product product; using(UnitOfWorkScope scope = new UnitOfWorkScope()) { Console.Out.WriteLine("Selecting..."); product = _productRepository.First(); Console.Out.WriteLine("Adding Product Vendor..."); product.AddProductVendor(_vendorRepository.First(), 0m); scope.Commit(); } Console.Out.WriteLine("About to delete Product Vendors..."); using (UnitOfWorkScope scope = new UnitOfWorkScope()) { Console.Out.WriteLine("Clearing Product Vendor..."); _productRepository.Save(product); // seems to be needed to attach entity to the persistance manager product.ProductVendors.Clear(); scope.Commit(); } } Going nuts here as I almost have a very nice solution between mvc, custom model binders and nhibernate. Just not seeing my deletes cascaded. Any help greatly appreciated. Chev

  • PHP hooks information and help needed

    - by sea_1987
    Background I am realtively new to hooks, and I have been asked to use a hook to populate a view with some data, currently the view gathers it data from a function that is in the model, and becuase the whole object is being passed to the view I can access the function. The function looks like this, public function numCVInSector($k) { $this->load->model('SYSector'); $sectorModel = new SYSector(); $cvs = $sectorModel->fetchRelatedCV($k); $cvs = $cvs[0]['count']; if($cvs == "0") { return false; } else { return $cvs; } } it call's a query in the model that looks like this, public function fetchRelatedCV($k) { $sql = "SELECT sector_id, COUNT(sector_id) as count FROM sy_user_sectors WHERE sector_id = $k"; //print_r($sql); $query = $this->db->query($sql); return $query->result_array(); } $k is the id of element that is in the view. The Problem I have been asked to use a hook that is in the parent of the model the hook is called post populate, now I have very little idea of what a hook is or how to use one to implement my function. Could some one give me some advice, the code where the hook is original made looks like this, public function populate($where = array()) { $results = array( "success" => false, "is_error" => false, "error_code" => "", "error_message" => "" ); if(empty($where) && empty($this->aliases['id'])){ $results['is_error'] = true; $results['error_message'] = 'No criteria.'; return $results; } // [hook] $this->prePopulate(); $where = count($where) > 0 ? $where : array('id' => $this->aliases['id']); $query = $this->db->get_where($this->tableName, $where, 1); if($query->num_rows() < 1){ $results['error_message'] = 'Empty results.'; return $results; } foreach($query->result_array() as $row){ foreach($this->aliases as $key => $val){ $this->aliases[$key] = $row[$key]; } } // [hook] $this->postPopulate(); // Presume success $results['success'] = true; return $results; } I have been asked to use the postPopulate hook. public function postPopulate() { $args = $this->getHookArgs('post_populate'); if(!is_array($args)){ // $this->fb->log($args, 'bad args'); return false; } // code here... // Convert dates to front end formats. foreach($this->frontEndDateFields as $fieldName => $dateFormat){ $dateRes = mlib_du_getFormattedMySQLDate($this->aliases[$fieldName], $dateFormat); if($dateRes != false){ $this->aliases[$fieldName] = $dateRes; } } return true; }

  • XmlNode.RemoveChild() recursive

    - by Lord Vader
    Hi, my problem is the following: How can I remove selected ChildNodes from XmlNode recursively? My XML-file looks like... ..<element type="TextBox" id="xslFilePath"> <parameters> <parameter id="description"> <value><![CDATA[Pfad zur XSL]]></value> <value lang="en"><![CDATA[XSL-file's path]]></value> </parameter> <parameter id="tooltip"> <value><![CDATA[Pfad zur XSL]]></value> <value lang="en"><![CDATA[XSL-file's path]]></value> </parameter> </parameters> <values> <value><![CDATA[/include/extensions/languageReferences/xsl/default.xsl]]></value> </values> </element> <element type="DropDownList" id="imageOrientation"> <parameters> <parameter id="description"> <value><![CDATA[Anordnung]]></value> <value lang="en"><![CDATA[Orientation]]></value> </parameter> <parameter id="tooltip"> <value><![CDATA[Anordnung]]></value> <value lang="en"><![CDATA[Orientation]]></value> </parameter> </parameters> <items> <item id="" selected="true"> <parameters> <parameter id="value"> <value><![CDATA[vertical]]></value> </parameter> <parameter id="description"> <value><![CDATA[senkrecht]]></value> <value lang="en"><![CDATA[vertical]]></value> </parameter> </parameters> </item> <item id="" selected="false"> <parameters> <parameter id="value"> <value><![CDATA[horizontal]]></value> </parameter> <parameter id="description"> <value><![CDATA[waagerecht]]></value> <value lang="en"><![CDATA[horizontal]]></value> </parameter> </parameters> </item> </items> <values> <value><![CDATA[horizontal]]></value> </values> </element>... I would like to remove all nodes (type of value) where the parentNode is type of parameter with id="description" but not value-notes as children of values or parameter with id="value" In XSLT I would say e.g.: //value[parent::parameter[@id='description'] and @lang='en']The problem is: I have the language code: e.g. "de" and now I would like to remove all sibling value nodes if an value with lang="de" exists and remove all sibling nodes excluding the value without any lang-attribute if lang="de" not exists (as fallback) I hope, you can help me to write an c# Code to replace recursively all undesired value-nodes.

  • ASP.MVC 1.0 complex ViewModel not populating on Action

    - by Graham
    Hi, I'm 3 days into learning MVC for a new project and i've managed to stumble my way over the multitude of issues I've come across - mainly about something as simple as moving data to a view and back into the controller in a type-safe (and manageable) manner. This is the latest. I've seen this reported before but nothing advised has seemed to work. I have a complex view model: public class IndexViewModel : ApplicationViewModel { public SearchFragment Search { get; private set; } public IndexViewModel() { this.Search = new SearchFragment(); } } public class SearchFragment { public string ItemId { get; set; } public string Identifier { get; set; } } This maps to (the main Index page): %@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IndexViewModel>" %> <asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server"> <% Html.BeginForm("Search", AvailableControllers.Search, FormMethod.Post); %> <div id="search"> <% Html.RenderPartial("SearchControl", Model.Search); %> </div> <% Html.EndForm(); %> </asp:Content> and a UserControl: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<SearchFragment>" %> <p> <label for="itemId"> <%= Html.Resource("ItemId") %></label> <%= Html.TextBox("itemId", Model.ItemId)%> </p> <p> <label for="title"> <%= Html.Resource("Title") %></label> <%= Html.TextBox("identifier", Model.Identifier)%> </p> <p> <input type="submit" value="<%= Html.Resource("Search") %>" name="search" /> </p> This is returned to the following method: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Search(IndexViewModel viewModel) { .... } My problem is that when the view model is rehydrated from the View into the ViewModel, the SearchFragment elements are null. I suspect this is because the default model binder doesn't realise the HTML ItemId and Identifier elements rendered inline in the View map to the SearchFragment class. When I have two extra properties (ItemId and Identifier) in the IndexViewModel, the values are bound correctly. Unfortunately, as far as I can tell, I must use the SearchFragment as I need this to strongly type the Search UserControl... as the control can be used anywhere it can operate under any parent view. I really don't want to make it use "magic strings". There's too much of that going on already IMO. I've tried prefixing the HTML with "Search." in the hope that the model binder would recognise "Search.ItemId" and match to the IndexViewModel "Search" property and the ItemId within it, but this doesn't work. I fear I'm going to have to write my own ModelBinder to do this, but surely this must be something you can do out-of-the-box?? Failing that is there any other suggestions (or link to someone who has already done this?) Here's hoping....

  • Populating a GridView with ImageViews dynamically/programmatically using a ImageAdapter

    - by Julian Vogels
    Hi folks, this is my first question at stackoverflow, but it's a little tricky already... I try to develop an Android App which allows the user to fetch data from flickr and show it in a gridview (with some nice 3D-Animation). After some adventures i got it almost running, but now I'm stuck. Here's the problem: I got a UI Thread "LoadPhotosTask" which gets the pictures from flickr, just like the open source application photostream. In the method onProgressUpdate(LoadedPhoto... value) of that subclass I call addPhoto(). Until now everythings fine - I got some nice Bitmap and Flickr.photo data with all the information I need. @Override public void onProgressUpdate(LoadedPhoto... value) { addPhoto(value); } On the other hand I have got a GridView. Now I want to fill it with the Photos. It has got an adapter called ImageAdapter (which extends BaseAdapter, see this tutorial). If I use an array inside the ImageAdapter class I can populate the GridView with some sample images. But if I want to populate it at runtime, I don't know what to do. How do I have to set up the getView method in the ImageAdapter? I was trying to fill the array inside the ImageAdapter class with my values in addPhoto, but it doesn't display anything. So first of all I was setting up the array with the amount of Photos i wanted to display in the grid like that (code is inside the ImageAdapter class): // class variable private ImageView[] mThumbIds; [...] public void setupArray(int count) { this.mThumbIds = new ImageView[count]; } Then I call this method with the lenght of my photolist: final Flickr.PhotoList list = params[0]; final int count = list.getCount(); int helper = 0; imagead.setupArray(count); Afterwards I call the getView method manually inside the addPhoto method: private void addPhoto(LoadedPhoto... value) { ImageView image = (ImageView) mInflater.inflate( R.layout.grid_item_photo, null); image.setImageBitmap(value[0].mBitmap); image.setTag(value[0].mPhoto); imagead.setmThumbIds(image, value[0].mPosition); imagead.getView(value[0].mPosition, null, mpicturesGrid); } That is the getView method inside ImageAdapter: public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { // if it's not recycled, initialize some // attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(EDGE_LENGTH, EDGE_LENGTH)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(0, 0, 0, 0); imageView.setVisibility(View.VISIBLE); } else { imageView = (ImageView) convertView; } imageView.setImageDrawable(mThumbIds[position].getDrawable()); imageView.setTag(mThumbIds[position].getTag()); return imageView; } Ok, finally I apologize for my poor english and I hope you can give me some help with the information I provided. Greetings, Julian

  • tkinter frame does not show on startup

    - by Jzz
    this is my first question on SO, so correct me please if I make a fool of myself. I have this fairly complicated python / Tkinter application (python 2.7). On startup, the __init__ loads several frames, and loads a database. When that is finished, I want to set the application to a default state (there are 2 program states, 'calculate' and 'config'). Setting the state of the application means that the appropriate frame is displayed (using grid). When the program is running, the user can select a program state in the menu. Problem is, the frame is not displayed on startup. I get an empty application (menu bar and status bar are displayed). When I select a program state in the menu, the frame displays as it should. Question: What am I doing wrong? Should I update idletasks? I tried, but no result. Anything else? Background: I use the following to switch program states: def set_program_state(self, state): '''sets the program state''' #try cleaning all the frames: try: self.config_frame.grid_forget() except: pass try: self.tidal_calculations_frame.grid_forget() except: pass try: self.tidal_grapth_frame.grid_forget() except: pass if state == "calculate": print "Switching to calculation mode" self.tidal_calculations_frame.grid() #frame is preloaded self.tidal_calculations_frame.fill_data(routes=self.routing_data.routes, deviations=self.misc_data.deviations, ship_types=self.misc_data.ship_types) self.tidal_grapth_frame.grid() self.program_state = "calculate" elif state == "config": print "Switching to config mode" self.config_frame = GUI_helper.config_screen_frame(self, self.user) #load frame first (contents depend on type of user) self.config_frame.grid() self.program_state = "config" I understand that this is kind of messy to read, so I simplified things for testing, using this: def set_program_state(self, state): '''sets the program state''' #try cleaning all the frames: try: self.testlabel_1.grid_forget() except: pass try: self.testlabel_2.grid_forget() except: pass if state == "calculate": print "switching to test1" self.testlabel_1 = tk.Label(self, text="calculate", borderwidth=1, relief=tk.RAISED) self.testlabel_1.grid(row=0, sticky=tk.W+tk.E) elif state == "config": print "switching to test1" self.testlabel_2 = tk.Label(self, text="config", borderwidth=1, relief=tk.RAISED) self.testlabel_2.grid(row=0, sticky=tk.W+tk.E) But the result is the same. The frame (or label in this test) is not displayed at startup, but when the user selects the state (calling the same function) the frame is displayed. UPDATE the sample code in the comments (thanks for that!) pointed me in another direction. Further testing revealed (what I think) the cause of the problem. Disabling the display of the status bar made the program work as expected. Turns out, I used pack to display the statusbar and grid to display the frames. And they are in the same container, so problems arise. I fixed that by using only pack inside the main container. But the same problem is still there. This is what I use for the statusbar: self.status = GUI_helper.StatusBar(self.parent) self.status.pack(side=tk.BOTTOM, fill=tk.X) And if I comment out the last line (pack), the config frame loads on startup, as per this line: self.set_program_state("config") But if I let the status bar pack inside the main window, the config frame does not show. Where it does show when the user asks for it (with the same command as above).
