Detecting the closing of a window

[Kosomot]

Hi all,

Well, I have a question: is there a way to detect when a user closes a GUI window (something like the WM_CLOSE message in WINAPI)?
This doesn't seem to work:

Code: Select all

IGUIWindow *wnd=gui->addWindow(...);
IGUIButton *btn=wnd->getCloseButton();
btn->setID(10);

...

//in the event reciever:
	switch(event.EventType)
	{
		case EET_GUI_EVENT:
			switch(event.GUIEvent.EventType)
			{
				case EGET_BUTTON_CLICKED:
				        switch(event.GUIEvent.Caller->getID())
				        {
				        case 10:
				              //do something
				              return true;
				        }
					break;
			}
			break;
	}
	return false;

Any ideas?[/code]

The close button has a default handler, so you won't get the event. There is a patch availabel to remove default handling. Search for it in the forums.

This is an idea that just came into my mind. It's a way without modifying the engine, although it has a hackish touch:

1. Get and hide the original close button (getCloseButton)
2. Create a new button with same configuration as the original one (text, font, position) and place it as child into the window.

The events of that "button clone" won't get catched by the window.
