Disabling Alt+F4

#1 Well I did this, but my code has lots of updates to the windowing, so you might run into something that doesn't jive with TGE 1.5.2, but I think this gives you the gyst of what you need to do.

Step 1.

Initialize a variable at the start of your game:

$Game::HasConfirmedQuit = false;

Step 2.
In winWindow.cc in the static LRESULT PASCAL WindowProc, you want the switch with the wParam to have a handler for SC_CLOSE

...
         switch(wParam)
         {
	  case SC_CLOSE:
	   Platform::postQuitMessage(0);
           return 0;
         case SC_KEYMENU:
         ...

Step 3.
In the Platform::process of winWindow.cc, you'd want something like

...
   if(!ProcessMessages())
   {
	   if (!Con::getBoolVariable("Game::HasConfirmedQuit"))
	   {
		  Con::evaluatef("toggleQuit();");
		  return;
	   }
      // generate a quit event
      Event quitEvent;
      ...

Step 4.
Now I'm assuming your toggleQuit function prompts the player if they really want to quit or not, so what you want to do is if they confirm that they indeed want to quit you set

$Game::HasConfirmedQuit = true;

then run a

quit();

#2 Thanks James! It almost worked, and I'm actually running Torque 1.4.

Is the switch(wParam) inside of "case WM_SYSCOMMAND:" ?

Basically what's happening now is that when I press Alt+F4, it is performing the toggleQuit function. But when I click Yes on the Quit GUI, it does nothing. This is what I have in the Yes button code:

function quitDlg::Yes_OnClick( %this )
{
	$Game::HasConfirmedQuit = true;
	echo("Yes button clicked");
	quit();
}

The variable is getting set, and the echo statement is being outputted, but for some reason the quit() is totally ignored.

#3 Oops, that code snippet should be:

if (!Con::getBoolVariable("Game::HasConfirmedQuit"))

not just

if (!Con::getBoolVariable("HasConfirmedQuit"))

#4 And yes, that switch is in case WM_SYSCOMMAND:

#5 It works like a charm! Thanks again, James. :)
