  • Simple Prototype.js code to select multiple elements with the same classname

    - by stephemurdoch
    I have one link with an id of "link", and I use the javascript below to open that link up in a modalbox: #In my template I have: <a href="some/path" id="link">link</a> #Then in my application.js file I have: document.observe('dom:loaded', function() { $('login-link').observe('click', function(event) { event.stop(); Modalbox.show(this.href,{title: 'some title', width: 500}); }); }) Since id's must be unique, this javascript only works for one element per page so I use it to observe my login-link and it has served me well. Until now. I want to use the same javascript to observe multiple links which have classnames instead of id's as below: <a href="link/to/some/stuff" class="link">link 1</a> <a href="link/to/some/other/stuff" class="link">link 2</a> When I do this, I can't get any of the links to open in a modalbox. If I change the class to an id for each link, then I can get the first link in the list to open in a modalbox. I've tried to use the '$$' notation to build an array of links in my javascript (shown below) but if I do that, then none of the links open correctly #document.observe method removed for display purposes $$('link').observe('click', function(event) { event.stop(); Modalbox.show(this.href,{title: 'some title', width: 500} ); }); My javascript skills obviously suck. Does anyone know how to fix the problem?

  • reddit style voting with django

    - by dotty
    Hay i need to hand implemeneting a voting system into a model. I've had a huge helping hand from Mike DeSimone making this work in the first place, but i need to expand upon his work. Here is my current code View def show_game(request): game = Game.objects.get(pk=1) discussions = game.gamediscussion_set.filter(reply_to=None) d = { 'game':game, 'discussions':discussions } return render_to_response('show_game', d) Template <ul> {% for discussion in discussions %} {{ discussion.html }} {% endfor %} </ul> Model class GameDiscussion(models.Model): game = models.ForeignKey(Game) message = models.TextField() reply_to = models.ForeignKey('self', related_name='replies', null=True, blank=True) created_on = models.DateTimeField(blank=True, auto_now_add=True) userUpVotes = models.ManyToManyField(User, blank=True, related_name='threadUpVotes') userDownVotes = models.ManyToManyField(User, blank=True, related_name='threadDownVotes') def html(self): DiscussionTemplate = loader.get_template("inclusions/discussionTemplate") return DiscussionTemplate.render(Context({ 'discussion': self, 'replies': [reply.html() for reply in self.replies.all()] })) DiscussionTemplate <li> {{ discussion.message }} {% if replies %} <ul> {% for reply in replies %} {{ reply }} {% endfor %} </ul> {% endif %} </li> As you can see we have 2 fields userUpVotes and userDownVotes on the model, these will calculate how to order the discussions and replies. How would i implement these 2 fields to order the replies and discussions based on votes? Any help would be great!

  • TFS 2010 Build gives WorkItemStore error when Create Work Item on Failure is enabled

    - by Derek Morrison
    I'm using TFS 2010 Build. I have a build definition that uses the DefaultTemplate.xaml template that's stock in TFS 2010, and the Create Work Item on Failure property is set to True in the build definition. I deliberately made a change in my project that breaks the build. When the build runs, I see the compilation error reflected in the TFS Build log within Visual Studio, but I get the error "Value cannot be null. Parameter name: WorkItemStore" when TFS Build next tries to generate a Work Item for the broken build. I tracked down the activity in DefaultTemplate.xaml (see the rather lengthy path to it below) where the Work Item is created for a broken build, and I see it uses the Microsoft.TeamFoundation.Build.Workflow.Activities.OpenWorkItem class to create the Work Item. The appropriate values seemed to be filled out in the Properties window for the Create Work Item activity, so I don't see where I can pass WorkItemStore to it and I don't even know appropriate values for this setting. Path to the Create Work Item activity: Process Sequence Run On Agent Try Compile, Test, and Associate Changesets and Work Items Sequence Compile, Test, and Associate Changesets and Work Items Try Compile and Test Compile and Test For Each Configuration in BuildSettings.PlatformConfigurations Compile and Test for Configuration If BuildSettings.HasProjectsToBuild For Each Project in BuildSettings.ProjectsToBuild Try to Compile the Project Handle Exception If CreateWorkItem Create Work Item for non-Shelveset Builds Create Work Item

  • Tal condition always evaluates to false

    - by Ander2
    I'm using plone and trying to display a form result in a page template. I'm trying to filter some database results using tal:condition with a python expression but it always evaluates to false. The code looks like this: <tr tal:repeat="result view/results"> <td> <span tal:condition="python:view.teams[0]==result.team_id" tal:replace="result/position">Position</span></td> <td> <span tal:condition="python:view.teams[1]==result.team_id" tal:replace="result/position">Position</span></td> </tr> I want the table cells to be filled with the team position when the team id is matched in the result, but the cells always are empty. If I remove the tal:condition from the span and replace the tal:replace="result/position" with tal:replace=python:view.teams[0]==result.team_id it prints True or False so I can check that the result is correct. Can anyone help me about this issue? Why does tal:condition allways evaluate false?

  • MS Access 2003 - Is there a way to programmatically define the data for a chart?

    - by Justin
    So I have some VBA for taking charts built with the Form's Chart Wizard, and automatically inserting it into PowerPoint Presentation slides. I use those chart-forms as sub forms within a larger forms that has parameters the user can select to determine what is on the chart. The idea is that the user can determine the parameter, build the chart to his/her liking, and click a button and have it in a ppt slide with the company's background template, blah blah blah..... So it works, though it is very bulky in terms of the amount of objects I have to use to accomplish this. I use expressions such as the following: like forms!frmMain.Month&* to get the input values into the saved queries, which was fine when i first started, but it went over so well and they want so many options, that it is driving the number of saved queries/objects up. I need several saved forms with charts because of the number of different types of charts I need to have this be able to handle. SO FINALLY TO MY QUESTION: I would much rather do all this on the fly with some VBA. I know how to insert list boxes, and text boxes on a form, and I know how to use SQL in VBA to get the values I want from tables/queries using VBA, I just don't know if there is some vba I can use to set the data values of the charts from a resulting recordset: DIM rs AS DAO.Rescordset DIM db AS DAO.Database DIM sql AS String sql = "SELECT TOP 5 Count(tblMain.TransactionID) AS Total, tblMain.Location FROM tblMain WHERE (((tblMain.Month) = """ & me.txtMonth & """ )) ORDER BY Count (tblMain.TransactionID) DESC;" set db = currentDB set rs = db.OpenRecordSet(sql) rs.movefirst some kind of cool code in here to make this recordset the data of chart in frmChart ("Chart01") thanks for your help. apologies for the length of the explanation.

  • Microsoft Reporting: Setting subreport parameters in code

    - by Svish
    How can I set a parameter of a sub-report? I have successfully hooked myself up to the SubreportProcessing event, I can find the correct sub-report through e.ReportPath, and I can add datasources through e.DataSources.Add. But I find no way of adding report parameters?? I have found people suggesting to add them to the master report, but I don't really want to do that, since the master report shouldn't have to be connected to the sub-report at all, other than that it is wrapping the sub-report. I am using one report as a master template, printing name of the report, page numbers etc. And the subreport is going to be the report itself. And if I could only find a way to set those report parameters of the sub-report I would be good to go... Clarification: Creating/Defining the parameters is not the problem. The problem is to set their values. I thought the natural thing to do was to do it in the SubreportProcessing event. And the SubreportProcessingEventArgs do in fact have a Parameters property. But it is read only! So how do you use that? How can I set their value?

  • Flipping View transition becomes clunky when using UIPickerViews with a large number of elements

    - by user302246
    I have a very simple app created with the Utility Application project template on XCode. My MainView has two UIPickerView components and two buttons. The FlipSideView has another UIPickerView. The pickers on the main view each have 4 segments and each segment has 8 rows. The picker on the flip side has just 1 segment with 8 rows. All rows on all pickers are just text. With just this setup, pressing the button to flip the view back and forth displays a noticeable delay before the animation actually starts, and then the animation actually seems to go faster than what it should, like it's trying to make up for the lost time. I removed the pickers in interface builder and loaded the app on the phone and the animation now seems natural. I also tried just one picker (the flipside one) and things still seem normal. So my current theory is that the number of objects involved in the main view is the cause. The thing is that I don't think it's that many (4 x 8 x 2 = 64), but I could be completely wrong. This is pretty much my first app so maybe I'm just doing something grossly wrong, or maybe the phone is has a lot more limited processing than I thought. I am thinking of creating the picker views with pickerView:viewForRow:forComponent:reusingView: to see if this hopefully performs better, but I'm not sure if this is just a waste of time. Any suggestions? Thanks Ruy P.S.: Testing on a 3G phone on 3.1.2

  • DataGrid: dynamic DataTemplate for dynamic DataGridTemplateColumn

    - by Lukas Cenovsky
    I want to show data in a datagrid where the data is a collection of public class Thing { public string Foo { get; set; } public string Bar { get; set; } public List<Candidate> Candidates { get; set; } } public class Candidate { public string FirstName { get; set; } public string LastName { get; set; } ... } where the number of candidates in Candidates list varies at runtime. Desired grid layout looks like this Foo | Bar | Candidate 1 | Candidate 2 | ... | Candidate N I'd like to have a DataTemplate for each Candidate as I plan changing it during runtime - user can choose what info about candidate is displayed in different columns (candidate is just an example, I have different object). That means I also want to change the column templates in runtime although this can be achieved by one big template and collapsing its parts. I know about two ways how to achieve my goals (both quite similar): Use AutoGeneratingColumn event and create Candidates columns Add Columns manually In both cases I need to load the DataTemplate from string with XamlReader. Before that I have to edit the string to change the binding to wanted Candidate. Is there a better way how to create a DataGrid with unknown number of DataGridTemplateColumn? Note: This question is based on dynamic datatemplate with valueconverter

  • Handling form from different view and passing form validation through session in django

    - by Mo J. Mughrabi
    I have a requirement here to build a comment-like app in my django project, the app has a view to receive a submitted form process it and return the errors to where ever it came from. I finally managed to get it to work, but I have doubt for the way am using it might be wrong since am passing the entire validated form in the session. below is the code comment/templatetags/comment.py @register.inclusion_tag('comment/form.html', takes_context=True) def comment_form(context, model, object_id, next): """ comment_form() is responsible for rendering the comment form """ # clear sessions from variable incase it was found content_type = ContentType.objects.get_for_model(model) try: request = context['request'] if request.session.get('comment_form', False): form = CommentForm(request.session['comment_form']) form.fields['content_type'].initial = 15 form.fields['object_id'].initial = 2 form.fields['next'].initial = next else: form = CommentForm(initial={ 'content_type' : content_type.id, 'object_id' : object_id, 'next' : next }) except Exception as e: logging.error(str(e)) form = None return { 'form' : form } comment/view.py def save_comment(request): """ save_comment: """ if request.method == 'POST': # clear sessions from variable incase it was found if request.session.get('comment_form', False): del request.session['comment_form'] form = CommentForm(request.POST) if form.is_valid(): obj = form.save(commit=False) if request.user.is_authenticated(): obj.created_by = request.user obj.save() messages.info(request, _('Your comment has been posted.')) return redirect(form.data.get('next')) else: request.session['comment_form'] = request.POST return redirect(form.data.get('next')) else: raise Http404 the usage is by loading the template tag and firing {% comment_form article article.id article.get_absolute_url %} my doubt is if am doing the correct approach or not by passing the validated form to the session. Would that be a problem? security risk? performance issues? Please advise Update In response to Pol question. The reason why I went with this approach is because comment form is handled in a separate app. In my scenario, I render objects such as article and all I do is invoke the templatetag to render the form. What would be an alternative approach for my case? You also shared with me the django comment app, which am aware of but the client am working with requires a lot of complex work to be done in the comment app thats why am working on a new one.

  • Best practises for Magento Deployment

    - by Spongeboy
    I am looking setting up a deployment process for a highly customised Magento site, and was wondering how other people do this. I will be setting up dev, UAT and prod environments. All the Magento files will be in source control (SVN). At this stage, I can't see any requirements for changing the DB, so the 3 databases will be manually maintained. Specifically, How do you apply Magento upgrades? (Individually in each env, or on dev then roll out, or just give up on upgrades?) What files/folders do leave alone in each environment (e.g. magento/app/etc/local.xml) Do you restrict developers to editing specific files/folders? Do you restrict theme designers to editing specific files/folders? How do you manage database changes? Theme Designer Files/Folders Designers can restricted to editing the following folders- app/design/frontend/your_interface/your_theme/layout/ app/design/frontend/your_interface/your_theme/template/ app/design/frontend/your_interface/your_theme/locale/ skin/frontend/your_interface/your_theme/ Extension Developer Files/Folders Extension developers can edit the following folders/files- /app/code/local /app/etc/modules/<Namespace>_<Module>.xml Database environment management As the store's base URL is stored in the database, you cannot just copy databases between environments. Options include- Overriding the base url in php. Blog article on setting up dev and staging databases Changing the base url in the database after copying. (Where is this stored?) Doing a MySQLDump or backup, then doing a replace on the URL in the SQL file.

  • How can I format the text in a databound TextBox?

    - by Abe Miessler
    I have ListView that has the following EditItemTemplate: <EditItemTemplate> <tr style=""> <td> <asp:LinkButton ID="UpdateButton" runat="server" CommandName="Update" Text="Update" /> <asp:LinkButton ID="CancelButton" runat="server" CommandName="Cancel" Text="Cancel" /> </td> <td> <asp:TextBox ID="FundingSource1TextBox" runat="server" Text='<%# Bind("FundingSource1") %>' /> </td> <td> <asp:TextBox ID="CashTextBox" runat="server" Text='<%# Bind("Cash") %>' /> </td> <td> <asp:TextBox ID="InKindTextBox" runat="server" Text='<%# Bind("InKind") %>' /> </td> <td> <asp:TextBox ID="StatusTextBox" runat="server" Text='<%# Bind("Status") %>' /> </td> <td> <asp:TextBox ID="ExpectedAwardDateTextBox" runat="server" Text='<%# Bind("ExpectedAwardDate","{0:MM/dd/yyyy}) %>' onclientclick="datepicker()" /> </td> </tr> </EditItemTemplate> I would like to format the "ExpectedAwardDateTextBox" so it shows a short date time but haven't found a way to do this without going into the code behind. In the Item template I have the following line to format the date that appears in the lable: <asp:Label ID="ExpectedAwardDateLabel" runat="server" Text='<%# String.Format("{0:M/d/yyyy}",Eval("ExpectedAwardDate")) %>' /> And I would like to find a similar method to do with the insertItemTemplate.

  • Making Vim auto-indent PHP/HTML using alternative syntax

    - by njbair
    I edit PHP in Vim and have enjoyed the auto-indenting, but PHP's alternative syntax doesn't auto-indent how I would like. For instance, in an HTML template, Vim doesn't recognize the open control structure in the same way it does when using braces. Example: <html> <body> <p> <?php if (1==1): ?> This line should be indented. <?php endif; ?> </p> </body> </html> I want Vim to recognize the open control structure and indent the HTML within it. Another example which uses pure PHP: <?php if (1==1): echo "This line gets indented"; echo "This one doesn't"; endif; ?> The indentation is terminated by the semicolon, even though the control structure is still open. Does anybody know how to get Vim to work in these situations? Thanks.

  • How to make a WPF ComboBox editable with custom values

    - by Liam
    I would like to have a combobox that allows selection from a list of values and also allow a custom value from the typed in text. For display reasons the items are a complex type (lets say the combobox item template displays a patch of color and a flag indicating if it is a custom color). public class ColorLevel { public decimal Intensity { get; set; } public bool IsCustom { get; set; } public Color BaseColor { get; set; } public override ToString() { return string.Format("{0}", Intensity*100); } } Example items var items = new [] { new ColorLevel { Intensity = 0.9m, IsCustom = false, BaseColor = Color.Red }, new ColorLevel { Intensity = 0.7m, IsCustom = false, BaseColor = Color.Red } } XAML <ComboBox SelectedItem="{Binding Path=SelectedColorLevel}" IsEditable="true" IsTextSearchEnabled="true"> </ComboBox> So the above markup works when an item is selected from the item list. And as you type with the text search the matching items are selected. If the typed text doesn't match an item then the SelectedColorLevel is set to null. The question is at what point (and how) is it best to create a new custom item that can be set to the SelectedColorLevel when the typed text doesn't match an item. For example I would want to assign a new item to the selected value such as new ColorLevel { Intensity = decimal.Parse(textvalue), IsCustom = true } or using an appropriate converter and databinding to the Text property.

  • Trouble with object injection in Spring.Net

    Hi all, I have a issue with my Spring.Net configuration where its not injecting an object. I have a CommService to which an object named GeneralEmail is injected to. Here is the configuration: <!-- GeneralMail Object --> <object id="GeneralMailObject" type="CommUtil.Email.GeneralEmail, CommUtil"> <constructor-arg name="host" value="xxxxx.com"/> <constructor-arg name="port" value="25"/> <constructor-arg name="user" value="[email protected]"/> <constructor-arg name="password" value="xxxxx"/> <constructor-arg name="template" value="xxxxx"/> </object> <!-- Communication Service --> <object id="CommServiceObject" type="TApp.Code.Services.CommService, TApp"> <property name="emailService" ref="GeneralMailObject" /> </object> The communication service object is again injected to many other aspx pages & service. In one scenario, I need to call the commnucation service from an static WebMethod. I try doing: CommService cso = new CommService(); But when i try to get the emailService object, its null! why didn't the spring inject the GeneralMail object into my cso object?

  • Having an issue with Nullable MySQL columns in SubSonic 3.0 templates

    - by omegawkd
    Looking at this line in the Settings.ttinclude string CheckNullable(Column col){ string result=""; if(col.IsNullable && col.SysType !="byte[]" && col.SysType !="string") result="?"; return result; } It describes how it determines if the column is nullable based on requirements and returns either "" or "?" to the generated code. Now I'm not too familiar with the ? nullable type operator but from what I can see a cast is required. For instance, if I have a nullable integer MySQL column and I generate the code using the default template files it returns a line similar to this: int? _User_ID; When trying to compile the project I get the error: Cannot implicitly convert type 'int?' to 'int'. An explicit conversion exists (are you missing a cast?) I checked teh Settings files for the other database types and they all seems to have the same routine. So my question is, is this behaviour expected or is this a bug? I need to solve it one way or the other before I can procede. Thanks for your help.

  • Why does C++ not allow multiple types in one auto statement?

    - by Walter
    The 2011 C++ standard introduced the new keyword auto, which can be used for defining variables instead of a type, i.e. auto p=make_pair(1,2.5); // pair<int,double> auto i=std::begin(c), end=std::end(c); // decltype(std::begin(c)) In the second line, i and end are of the same type, referred to as auto. The standard does not allow auto i=std::begin(container), e=std::end(container), x=*i; when x would be of different type. My question: why does the standard not allow this last line? It could be allowed by interpreting auto not as representing some to-be-decuded type, but as indicating that the type of any variable declared auto shall be deduced from its assigned value. Is there any good reason for the C++11 standard to not follow this approach? There is actually a use case for this, namely in the initialisation statement of for loops: for(auto i=std::begin(c), end=std::end(c), x=*i; i!=end; ++i, x+=*i) { ... } when the scope of the variables i, end, and x is limited to the for loop. AFAIK, this cannot be achieved in C++ unless those variables have a common type. Is this correct? (ugly tricks of putting all types inside a struct excluded) There may also be use cases in some variadic template applications.

  • google maps not working anymore at the drop of a hat

    - by Vordreller
    2 days ago, I was working on a project that involves google maps. The website showed the maps on the pages just fine. Now, I come back to my workstation, nothing has changed, expect for the fact that the google maps won't show up anymore. The code is identical, nobody has touched my machine since I was gone, I've checked the html, everything is perfect and still this isn't working... The Javascript console is giving no errors and the code is identical to a backup I make everytime I call it a day. 2 days ago it was working, today it isn't. I've even copied the source code, put it into an html file and tried that, but the same result. I'm at a loss here. This is my code: <script type="text/javascript"> //<![CDATA[ var map; var directionsPanel; var directions; function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("map")); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); //the route description directionsPanel = document.getElementById("route"); directions = new GDirections(map, directionsPanel); directions.load({COMMAND}); } } //]]> </script> The {COMMAND} is something that the PHP template will parse, I've checked it, the format is 100% correct and like I allready said, code now is identical to the backup, and if it worked back then, it should work now. Did google update their API overnight and did a function that I use here become deprecated? I don't know what's going on here...

  • My 3D object (opengl es) is disappearing behind the iPhone camera view

    - by KLC
    I have an augmented reality iPhone app that I am converting from Core Animation to OpenGL ES 1.1. I have added code that has been modified from the Apple OpenGL template. My problem is that my 3D object , when translating along the negative Z-axis (away from the user), appears to disappear into the camera view, until its completely gone. I have experimented with several solutions, but to no avail. What I have determined: Using the 3D icosahedron from Jeff Lamarche's blog here, the object starts it at 0,0,0 and then translates with decreasing z coordinates. By the time the z value reaches -2.0f, the object is gone. It appears as if it is disappearing behind the camera view. This is how I set my frustrum & viewport (unchanged from Apple's code) glMatrixMode(GL_PROJECTION); size = zNear * tanf(DEGREES_TO_RADIANS(fieldOfView) / 2.0); //Grab the size of the screen CGRect rect = self.bounds; glFrustumf(-size, size, -size / (rect.size.width / rect.size.height), size / (rect.size.width / rect.size.height), zNear, zFar); glViewport(0, 0, rect.size.width, rect.size.height); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); What I have tried: The camera view is the main view and several other views are added to it as subviews, including the openGLView. I have commented those views out for test purposes. I have applied CATransforms to move the openGLView in the z direction -500 and +500, and done the same to the camera view. I have also changed the zFar in the above code to 1.0f, and it still disappears at z position of -2.0, which doesn't make sense (shouldn't it disappear at z=1.0?) My experimentation has got me more confused than when I started ( which usually means I am missing a key piece, but I can't figure out what). Thanks for your help.

  • boost::asio::async_resolve Problem

    - by Moo-Juice
    Hi All, I'm in the process of constructing a Socket class that uses boost::asio. To start with, I made a connect method that took a host and a port and resolved it to an IP address. This worked well, so I decided to look in to async_resolve. However, my callback always gets an error code of 995 (using the same destination host/port as when it worked synchronously). code: Function that starts the resolution: // resolve a host asynchronously template<typename ResolveHandler> void resolveHost(const String& _host, Port _port, ResolveHandler _handler) const { boost::asio::ip::tcp::endpoint ret; boost::asio::ip::tcp::resolver::query query(_host, boost::lexical_cast<std::string>(_port)); boost::asio::ip::tcp::resolver r(m_IOService); r.async_resolve(query, _handler); }; // eo resolveHost Code that calls this function: void Socket::connect(const String& _host, Port _port) { // Anon function for resolution of the host-name and asynchronous calling of the above auto anonResolve = [this](const boost::system::error_code& _errorCode, boost::asio::ip::tcp::resolver_iterator _epIt) { // raise event onResolve.raise(SocketResolveEventArgs(*this, !_errorCode ? (*_epIt).host_name() : String(""), _errorCode)); // perform connect, calling back to anonymous function if(!_errorCode) connect(*_epIt); }; // Resolve the host calling back to anonymous function Root::instance().resolveHost(_host, _port, anonResolve); }; // eo connect The message() function of the error_code is: The I/O operation has been aborted because of either a thread exit or an application request And my main.cpp looks like this: int _tmain(int argc, _TCHAR* argv[]) { morse::Root root; TextSocket s; s.connect("somehost.com", 1234); while(true) { root.performIO(); // calls io_service::run_one() } return 0; } Thanks in advance!

  • ipad tabbar rotation

    - by MaKo
    hi, please help with this noob questions but really making me go crazy if I create a project from scratch (using windows based app) for the ipad, and add a tabbar , with firstviewController, and secondviewController, it works fine, starts in landscape mode, but in info.plist I set it to Landscape(left home button), but really in simulator starts with the button on the right side! in the FirstViewController.m (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) return YES; else { return NO; }} so it starts in landscape, and rotates as the simulator rotates, but if I create a template app for iphone tabbar, set the info.plist Initial interface orientation Landscape (left home button) and add the code above, IT DOESNT WORK!!! simulator starts with button at left but tab bar on the side, same problem that I had with an app that Im porting from iphone to ipad, (landscape intended) I get to the landscape start mode, but the tab bar remains on the side! also the only way to make the old ported app to show the simulator on the side was with UIInterfaceOrientation UIIntefaceOrientationLandscapeLeft (didnt work with Initial interface orientation), does not let me choose the value for the key, but it shows the simulator on landscape,, so,, what can I do please to show the tab bar on landscape mode??? the tabbar from scratch was made to see if the code will work , but it didnt?? why does it work in the tab bar made from windows app and not tab bar app? I just want the tab bar to show in landscape ahhh, thanks

  • Qt and variadic functions

    - by Noah Roberts
    OK, before lecturing me on the use of C-style variadic functions in C++...everything else has turned out to require nothing short of rewriting the Qt MOC. What I'd like to know is whether or not you can have a "slot" in a Qt object that takes an arbitrary amount/type of arguments. The thing is that I really want to be able to generate Qt objects that have slots of an arbitrary signature. Since the MOC is incompatible with standard preprocessing and with templates, it's not possible to do so with either direct approach. I just came up with another idea: struct funky_base : QObject { Q_OBJECT funky_base(QObject * o = 0); public slots: virtual void the_slot(...) = 0; }; If this is possible then, because you can make a template that is a subclass of a QObject derived object so long as you don't declare new Qt stuff in it, I should be able to implement a derived templated type that takes the ... stuff and turns it into the appropriate, expected types. If it is, how would I connect to it? Would this work? connect(x, SIGNAL(someSignal(int)), y, SLOT(the_slot(...))); If nobody's tried anything this insane and doesn't know off hand, yes I'll eventually try it myself...but I am hoping someone already has existing knowledge I can tap before possibly wasting my time on it.
