  • What is the component a popup menu click originated from

    - by Ralph Rickenbach
    Having a popup menu attached to several components on a form (buttons, but also things like TCharts), I would like to know which component was right clicked to start the popup menu in the first place. The Sender parameter of the click method just points to the TMenuItem, its parent to the popup menu (or the parenting menu item). How do I get the originating component?

  • Hibernate3: Self-Referencing Objects

    - by monojohnny
    Need some help on understanding how to do this; I'm going to be running recursive 'find' on a file system and I want to keep the information in a single DB table - with a self-referencing hierarchial structure: This is my DB Table structure I want to populate. DirObject Table: id int NOT NULL, name varchar(255) NOT NULL, parentid int NOT NULL); Here is the proposed Java Class I want to map (Fields only shown): public DirObject { int id; String name; DirObject parent; ... For the 'root' directory was going to use parentid=0; real ids will start at 1, and ideally I want hibernate to autogenerate the ids. Can somebody provide a suggested mapping file for this please; as a secondary question I thought about doing the Java Class like this instead: public DirObject { int id; String name; List<DirObject> subdirs; Could I use the same data model for either of these two methods ? (With a different mapping file of course). --- UPDATE: so I tried the mapping file suggested below (thanks!), repeated here for reference: <hibernate-mapping> <class name="my.proj.DirObject" table="category"> ... <set name="subDirs" lazy="true" inverse="true"> <key column="parentId"/> <one-to-many class="my.proj.DirObject"/> </set> <many-to-one name="parent" class="my.proj.DirObject" column="parentId" cascade="all" /> </class> ...and altered my Java class to have BOTH 'parentid' and 'getSubDirs' [returning a 'HashSet']. This appears to work - thanks, but this is the test code I used to drive this - I think I'm not doing something right here, because I thought Hibernate would take care of saving the subordinate objects in the Set without me having to do this explicitly ? DirObject dirobject=new DirObject(); dirobject.setName("/files"); dirobject.setParent(dirobject); DirObject d1, d2; d1=new DirObject(); d1.setName("subdir1"); d1.setParent(dirobject); d2=new DirObject(); d2.setName("subdir2"); d2.setParent(dirobject); HashSet<DirObject> subdirs=new HashSet<DirObject>(); subdirs.add(d1); subdirs.add(d2); dirobject.setSubdirs(subdirs); session.save(dirobject); session.save(d1); session.save(d2);

  • Is there anyway to stop automatic DataContext inheritance in Silverlight?

    - by Ant
    Is there anyway to stop automatic DataContext inheritance in Silverlight? I Set my DataContext on my parent UserControl in code. As a result all the xaml bindings inside the UserControl try to bind to the new DataConext they get (through the automatic DataContext Inheritance). The DataContext's for the children elements (actually they are children of children of children) of the UserControl is something I need to set in the UserControl's code... I don't want them being all smart because they end up binding to the wrong data object! :-)

  • Abstract classes and Pod::Coverage

    - by Ken Williams
    I've recently started to try to use Dist::Zilla for maintaining Path::Class. I added the [PodCoverageTests] plugin, and it's reporting some failures in the Path::Class::Entity class, which is the abstract base class for Path::Class::File and Path::Class::Dir. What I'd like is some way to tell the testing code that Entity doesn't need docs, but its two derived classes do - even though the methods are only defined in the parent class. Anyone know some way to do that?

  • How to hide the title bar for an Activity in XML

    - by Janusz
    I want to hide the title bar for some of my activities. The problem is that I applied a style to all my activities, therefore I can't simply set the theme to @android:style/Theme.NoTitleBar. Using the NoTitleBar theme as a parent for my style would remove the title bar for to much activities. Can I set a no title style item somewhere?

  • Sharepoint page level security

    - by ifunky
    Hi, Another SharePoint question from myself! I've created a subsite and from within Sharepoint designer I've created a new aspx page, all nice and simple so far. I can't seem to find where I can change the security on this new page, only site admins can view the page and everyone else gets access denied. It doesn't seem to inherit the permissions from the parent and I can't see where to change the security settings! Please help, I'm sure it's something simple! Thanks Dan

  • Keep div:hover open when changing nested select box

    - by JMC Creative
    This is an IE-only problem. .toolTip becomes visible when it's parent element is :hovered over. Inside of .toolTip is a select box. When the user opens the select box to make a selection, the parent element is being "un-hovered", if you will. To put it another way, when I try to select something from the dropdown, the whole thing hides itself again. I'm sure it has something to do with the way IE interprets the stylesheet, but I don't know what or where. Here is some relevant code (edited for clarity): #toolBar .toolTip { position: absolute; display:none; background: #fff; line-height: 1em; font-size: .8em; min-width: 300px; bottom: 47px; left: -5px; padding: 0 ; } #toolBar div:hover .toolTip { display:block; } and <div id="toolBar"> <div class="socialIcon"> <a href=""><img src="/im/social/nytimes.png" alt="NY Times Bestsellers" /></a> <span class="toolTip"> <h1>NY Times Bestsellers Lists</h1> <div id="nyTimesBestsellers"> <?php include('/ny-times-bestseller-feed.php') ?> </div> <p><img src="/im/social/nytimes.png" alt="NY Times Bestseller Lists" /> Change List <select id="nyTimesChangeCurrentList" name="nyTimesChangeCurrentList"> <option value="hardcover-fiction">Hardcover Fiction</option> <option value="hardcover-nonfiction">Hardcover Nonfiction</option> <option value="hardcover-advice">Hardcover Advice</option> </select> </p> </span> </div> </div>

  • How do you override ProgramFilesFolder in an msi?

    - by Mark
    I have an msi file that I am trying to install in a place other than C:\Program Files. The directory table shows that ProgramFilesFolder is used as the default install directory. From reading this blog post I understand that ProgramFilesFolder is a standard directory so passing TARGETDIR as a property to the installer will not change the install location even through the directory table has it as the parent of ProgramFilesFolder. How can I override the install location? I am a total novice in this area.

  • Win32: How do I get the listbox for a combobox

    - by Adam Tegen
    I'm writing some code and I need to get the window handle of the listbox associated with a combo box. When looking in spy++, it looks like the parent of the listbox is the desktop, not the combo box. How can I programmatically find the listbox window handle? I know I'd be looking for a window class of ComboLBox that belongs to my process, but how do I narrow that down to the specific one I am looking for? Adam

  • How can I unattach an element from another element in the XAML tree?

    - by Edward Tanguay
    In my Silverlight application, I load all the images I need at application start and store them in a dictionary. Then as I need them I pick them out of the dictionary and attach them in XAML trees etc. However, I have the problem that if I attach an Image object to a Grid, then want to use that image again, it tells me: The image element is already a child of another element. How can I run through my dictionary and "detach all images from parent XAML elements"?

  • Can someone who understands C code help me understand this code?

    - by Benjamin
    INT GetTree (HWND hWnd, HTREEITEM hItem, HKEY *pRoot, TCHAR *pszKey, INT nMax) { TV_ITEM tvi; TCHAR szName[256]; HTREEITEM hParent; HWND hwndTV = GetDlgItem (hWnd, ID_TREEV); memset (&tvi, 0, sizeof (tvi)); hParent = TreeView_GetParent (hwndTV, hItem); if (hParent) { // Get the parent of the parent of the... GetTree (hWnd, hParent, pRoot, pszKey, nMax); // Get the name of the item. tvi.mask = TVIF_TEXT; tvi.hItem = hItem; tvi.pszText = szName; tvi.cchTextMax = dim(szName); TreeView_GetItem (hwndTV, &tvi); //send the TVM_GETITEM message? lstrcat (pszKey, TEXT ("\\")); lstrcat (pszKey, szName); } else { *pszKey = TEXT ('\0'); szName[0] = TEXT ('\0'); // Get the name of the item. tvi.mask = TVIF_TEXT | TVIF_PARAM; tvi.hItem = hItem; tvi.pszText = szName; tvi.cchTextMax = dim(szName); if (TreeView_GetItem (hwndTV, &tvi)) //*pRoot = (HTREEITEM)tvi.lParam; //original hItem = (HTREEITEM)tvi.lParam; else { INT rc = GetLastError(); } } return 0; } The block of code that begins with the comment "Get the name of the item" does not make sense to me. If you are getting the listview item why does the code set the parameters of the item being retrieved, because if you already had the values there would be no need to retrieve them. Secondly near the comment "original" is the original line of code which will compile with a varning under embedded visual c++, but if you copy the exact same code into visual studio 2008 it will not compile. Since I did not write any of this code and am trying to learn is it possible the original author made a mistake on this line, since the *pRoot should point to and HKEY type yet he is casting to an HTREEITEM type which should never work since the data types don't match? (Side note someone with a better reputation should add a windows ce tag to SO since windows mobile is not the same as windows ce.)

  • Rails 3 Abstract Class vs Inherited Class

    - by R. Yanchuleff
    In my rails 3 model, I have two classes: Product, Service. I want both to be of type InventoryItem because I have another model called Store and Store has_many :InventoryItems This is what I'm trying to get to, but I'm not sure how to model this in my InventoryItem model and my Product and Service models. Should InventoryItem just be a parent class that Product and Service inherit from, or should InventoryItem be modeled as a class abstract of which Product and Service extend from. Thanks in advance for the advice!

  • Flex 4: Component move event

    - by alexey
    I have a CustomTextInput component based on TextInput (Spark) component. The instance of this class is placed on a popup window (TitleWindow). How can I capture the popup move (dragging the title) event inside CustomTextInput implementation? MoveEvent.MOVE event of the CustomTextInput itself doesn't work. Of course, I can't access the parent popup window inside the component implementation, because it's a common component that can be used not only on the popup windows.

    - by pigfox
    I'm attempting to use a Model but I get a fatal error so I assume it doesn't autoload properly. ErrorException [ Fatal Error ]: Class 'Properties_Model' not found The offending controller line: $properties = new Properties_Model; The model: class Properties_Model extends Model { public function _construct() { parent::_construct(); } } I also put the class in three different locations hoping one would work, all there failed. They are: application/classes/model application/model application/models What am I missing?

  • jQuery action being called when selector isn't met?

    - by dougoftheabaci
    I've been working on a prototype for a client's web site and I've run into a rather significant snag. You can view the prototype here. As you can see, the way it works is you can scroll a set of slides horizontally and, by clicking one, open a stack containing yet more slides. If you then click again on an image in that stack it opens up a lightbox. Clicking on another stack or the close button will close that stack (and open another, as case may be). That all works great. However you get some weird behavior if you do the following: Click to open any stack. Click to open an image's light box (this works best if you click on the image that's level with the main list). Close the light box and the stack either by clicking the close button or clicking on another stack. Click back to the first stack. Instead of reopening the stack, you get the lightbox. This confuses me as the light box should only ever be called if there is a class on the containing UL and that class is removed when the lightbox is closed. I've checked and double-checked this, it's definitely missing. Here are the respective functions: $("ul.hide a.lightbox").live("click",function(){ $("ul.show").removeClass("show").addClass("hide"); $(this).parent().parent().removeClass("hide").addClass("show"); $("ul.hide").animate({opacity: 0.2}); $("ul.show").animate({opacity: 1}); $("#next").animate({opacity: 0.2}); $("#prev").animate({opacity: 0.2}); return false; }); $("ul.show a.lightbox").live("click",function(){ $(this).fancybox().trigger("click"); return false; }); As you can see, in order for the lightbox to be called the containing UL has to have the class of show. However, if you check it with Firebug it won't. For those who are curious, the added .trigger("click"); is because the lightbox will require a double-click to launch otherwise. Any idea how I can fix this?

  • Is it possible to renice a subprocess ?

    - by ramusus
    I know about os.nice() it works perfect for parent process, but I need to do renice of my child subprocesses. I found way to do this, but it seems to be not very handy and too excessive: os.system("renice -n %d %d" % ( new_nice, suprocess.pid ) ) And it isn't return resulting nice level after renicing. Is there more clean way to renice subprocesses in python?

  • Twitter Bootstrap Navbar blocking svg viewBox

    - by user1167650
    I have a navbar fixed to the bottom and I have page that has a title and a giant svg (created by d3.js). I would like the svg to take up the entire screen (whatever is left over), but it always seems to have some part appear behind the bottom nav bar. I've tried: 1) using viewBox to auto-resize, setting the parent div and the svg to be block elements 2) adding padding-bottom to the body element But the svg still appears behind the navbar on wide screen monitors.
