Re: Destroy signal: Quit Y/N?

["Matt M." <matt boda virtualave net>]

Actually there is a way to do it. Display the quit y/n dialog in the callback,
and create a loop:
	 while (quitApp==0) { 
		/* loop here */ 
	}

	if(quitApp==1)
	{
		gtk_main_quit();
	}
	else { return; }
	
When the yes button is clicked, set quitApp to something besides 0. To make
this work (since you'll need to use another calleback for the
button_press_event on the yes and no buttons, make quitApp global, that way
when set to 1 or whatever, the while loop will see it. In this example 1 will
cause it to quit, any other value will cause it to return and not quit.
