    Nice job! I love that you even included a sample with your code.

  2. Hi

    Brillinant functionality. I just have one problem , I have added to swc to my build path , add the demo code with no issues in Flex Builder 3 demo but when I run the application off my Jboss server I get the following error :

    unable to load SWC ResizableTitleWindow.swc

    Exception flex2.compiler.swc.SwcException$SwcNotLoaded

    Any ideas on what the problem could be.

  4. Michel says:

    I have included the swc in the library path of the project (with flexbuilder 2) and I get the following error : unable to load SWC ResizableTitleWindow.swc.

    Am i missing some prerequisite ? Do you have an idea that could help ?

    Thanks in advance.


  5. nisheet says:

    I dont understand why that should not work. Can you guys be little more specific?

    BTW fyi I have done some bug fixing in the code and you guys might me interested in updating yourself.

  6. nisheet says:

    Are you guys adding the namespace of the swc in your application

    I’ve a problem with this component. I’m trying to use ResizeableTitleWindow as PopUp but it’s giving the following Error #1034: Type Coercion failed: cannot convert _PopUpEXp_mx_managers_SystemManager@46140b1 to mx.core.IUIComponent.

    And also some times resize cursor is getting strucked after resizing the component.

    I’m using the Flex Builder 3 beta (moxie). I installed your component, and I am getting the following error:

    Declaration of style ‘leading’ conflicts with previous declaration in C:\Program Files\Adobe\Flex Builder 3\sdks\moxie\frameworks\libs\ResizableTitleWindow.swc(mx/controls/ToolTip).

    I checked the online docs, and ToolTip does have a style named leading. However, I also searched through the source code of the component (in the src folder) and the word leading didn’t come up. Just in case the source wasn’t consistent with the binary, I rebuilt the swc, and I’m still getting this error. Do you have any idea where you hid the ‘leading’ style?


  9. Andy says:

    What license is this released under?

  10. Andy says:

    For me it fails because of the catalog… I suspect flex 3 vs 2?

  11. Andy says:

    The Component is very useful and wow…thanks for share your knowledge…

    Hi Nisheet,

    I have used your ResizableTitleWindow component in my FlexSpy component.
    Check it out at

  15. Prashant Shelke says:

    In order to solve “unable to load particular .swc file:multiple points”
    this error, download source project for that .swc file, copy it in workspace,
    then import in mysclipse.
    As soon as project will get import, new swc will create.Now use that newly created .swc to get rid of problem 🙂

  16. Yev says:

    Looks like this will only compile under Flex 3. Some of the imports are not there in v.2

    Very nice component, I wish i could use it.

  17. I have the same problem as Max Zimet:

    Declaration of style ‘leading’ conflicts with previous declaration in C:\Dev\Flex\3\SDK\frameworks\libs\framework.swc(mx/core/UITextField).

    I’m not sure where the mutiple i.e. second, declaration is coming from.

    This is FB3 on WinXP

    Help. Cheers

    Just a quick question, what kind of license is it? MIT…


  19. Samuel says:

    Hi, i’m using the mx:ResizableTitleWindow as a Component. And i’m using this line to call it.
    When i click the button to create the popup, i get
    Main Thread (Suspended: TypeError: Error #1034: Type Coercion failed: cannot convert meter@436d851 to meterTest.)
    What am i doing wrong, i’ve followed the steps for the installation already.

  20. Jana says:

    Hi, Very nice component. I’m having problems though with the icons. When I maximize the window the icon doesn’t change so it is unclear that if I select the same icon that the window size will return to its original size. I have also found the same to be true when I minimize the window I don’t see a restore icon show up.

  21. Matt says:

    I can get it to work but when I add multiple windows when I click the buttons on the first one, it operates on the last one that was created as opposed to the one I clicked on.

    Not sure why this is?

  22. Basil says:


    Great component, but how does the close button works, does it remove the window from memory (as a window would close in windows) or does it just becomes invisible (somewhat like a window would close on a mac)?

    Thanks in advance

  23. Matchu says:

    Great peice of code. Have been looking for something like this for awhile. Even tried to create one myself but haven’t learned enough yet. At any rate, is there a way to have the window start minimized? Thanks.

  24. Tian says:


    The ResizableTitleWindow is working beautifully for minimized, maximized and restored functions. However when I added many of the resizable windows, the drag and drop actions got the overlapped problem.

    I would greatly appreciate that the Author can post the drag and drop code also to solve the overlapping problem on the ResizableTitleWindow call.

  25. Haitham says:

    I am using the following code:

    SearchResultsWindow = PopUpManager.createPopUp(this, SearchResults, false);

    where SearchResults.mxml contains my ResizableTitleWindow. But when i run the code, I get the following error:

    TypeError: Error #1009: Cannot access a property or method of a null object reference.

    What’s going on??

    I have the same question, how do you get this to work with popupmanager? I.e. I am also trying to do a PopupManager.createPopUp(this, theresizablewindow, false)
    and getting a
    Type Coercion failed: cannot convert __mx_managers_SystemManager@ to mx.core.IUIComponent.

    Any ideas?

  31. blackth3red says:
