I need to break a while loop when the use clicks the close button on the window, but I don't know what to check for. I'm using allegro to run the GUI.
If using Allegro 4: set_close_button_callback()
volatile int hit_closed = 0;
void close_button_proc()
{
hit_closed = 1;
}
// later after creating the display:
set_close_button_callback(close_button_proc);
while (!hit_closed)
{
}
With Allegro 5, it's more like:
al_register_event_source(queue, al_get_display_event_source(display));
// in your event loop:
if (event.type == ALLEGRO_EVENT_DISPLAY_CLOSE) {
}
See the manual for all the details.
