[SOLVED] Window hangs around after deletion

[mmixLinus]

Hi!

After destroying the child (a Listbox called "WebPopupMenu") of an RTT GUIContext root window, it is still visible. I want it gone!

Code: Select all

   CEGUI::Window   *root = CApplication::getSingleton().getGUIContext(m_sOverlayName)->getRootWindow();
      CEGUI::Listbox *lb = static_cast<CEGUI::Listbox *>(root->getChild(POPUPMENU_NAME));
      root->destroyChild(lb);
//      root->destroyChild(POPUPMENU_NAME);


The Listbox IS deleted from the CEGUI window tree (I know, because I can create it again (same name)). Even doing an "lb->setVisible(false)" has no effect.

Any ideas what's wrong? Seems like the root window isn't updated after the destroyChild(). I can see that my other buttons are updated because they highlight properly when I hover over them. I tried root->invalidate(true) after destroyChild() but no change.. Maybe the Listbox area isn't cleared because the root window is transparent?

Code: Select all

Start of layout of GUI Context root window:

Code: Select all

<GUILayout version="4">
  <Window type="DefaultWindow" name="Overlay_WebPage">
    <Property name="InheritsAlpha"                value="False" />
    <Property name="Alpha"                      value="1.0" />
    <Property name="Visible"                      value="True" />
    <Property name="Position"            value="{{0.0,0},{0.0,0}}" />
    <Property name="Size"                value="{{1.0,0},{1.0,0}}" />
    <Property name="MaxSize"             value="{{1.0,0},{1.0,0}}" />
    <Property name="AlwaysOnTop"                value="False" />
    <Property name="MousePassThroughEnabled"    value="True" />
     <Event    name="Clicked"                    function="handlerOverlayClicked" />


The Listbox is destroyed:

Why do you only post the start of the layout?

Ident, sorry, I thought my problem was due to some crucial root window setting. However I SOLVED it a minute ago, hehe. I was missing this, silly me:

Code: Select all

         static_cast<CEGUI::TextureTarget&>(guic->getRenderTarget()).clear();

AND it solved THIS! My old RTT Alpha weirdness from almost two years ago! Admittedly, I haven't been working on this code for almost that long But my smooth alpha shadows look just great!

Yes, I know, I know!! I am using that page! (Obviously with bits missing )
