So far, I've managed to get a few main UI screens working. I can click buttons and go forward and backward between them.

I now want to be able to show modal message boxes over the top, for instance an 'Are you sure? Yes/No' window. I'd like the main menu screen to still be visible in the background, but be unresponsive.

I'm switching main menu screens by calling:

Code: Select all

CEGUI::System::getSingleton().setGUISheet( sheet );

If I use this for my message box, the message box appears, but I lose the menu behind.

I tried to remove my calls to setGUISheet, in the hope that I could just manually control the visibility and enabled state as I switch around. However I can't find another way to make my windows appear other than setGUISheet.

I've already tried these tempting functions:

Code: Select all

   sheet->activate( );
   sheet->show( );

Fwiw, I'm using the layout editor to build my sheets. currently I just call:

Code: Select all

CEGUI::WindowManager::getSingleton().loadWindowLayout( filename )

and then setGUISheet.

If someone could point me in the right direction, that would be great.

Thanks,
Duck

In order to manage all my Dialog windows, here is what I'm doing :

First, I initialise a general "default window" with the following code :

Code: Select all

mGUI = new CEGUI::OgreCEGUIRenderer(mWindow, Ogre::RENDER_QUEUE_OVERLAY, false, 0);
mGUISystem = new CEGUI::System(mGUI);
CEGUI::SchemeManager::getSingleton().loadScheme(schema);
mGUISystem->setDefaultMouseCursor(lookMouse, mouseCurseur);
mGUISystem->setDefaultFont(fontDefaut);
mRootGuiSheet = CEGUI::WindowManager::getSingleton().createWindow("DefaultGUISheet", "root");
mGUISystem->setGUISheet(mRootGuiSheet);

When the Ogre sceneManager is known I call

Code: Select all

mGUI->setTargetSceneManager(mSceneMgr);

Then each time I need a dialog window (such as a messageBox, or inputBox like in VB) I do the following:

Code: Select all

mWinDialog = CEGUI::WindowManager::getSingleton().loadWindowLayout("MsgBox.xml", mIdent); 
mGUISystem->addChildWindow(mWinDialog);
mWinDialog->addEvent(EventReponse);
mWinDialog->setModalState(true);

EventReponse being an event fired by the dialog

Then with a set of appropriate methodes such as:

Code: Select all

bool handleMsgBoxReponse(const CEGUI::EventArgs& e)
{
   const MsgEventArgs& msgArgs = static_cast<const MsgEventArgs&>(e);
   if (msgArgs.reponse == MSG_REP_OUI) 
   {
      <process the answer Yes...>;
   } else {
      <process the answer No...>;
   }
   return true;
}

I can manage all my dialogs...

Hope it help

Great,

Code: Select all

mGUISystem->addChildWindow(mWinDialog)

This was the bit I was missing.
So I now still use setGUISheet for changing the main page, but will just add/remove the temporary message boxes as child windows...

Thanks!
