Thanks, I finally figured it out, boy is it a weird and hostile api, in
Java I have straightforward window iconify/deiconify events, I don't have
to know/figure out to decrypt old and new event states.
Here:
bool
Window::stateEvent(GdkEventWindowState *pEvent) {
const int state = pEvent->new_window_state;
const int changed = pEvent->changed_mask;
if(changed & GDK_WINDOW_STATE_ICONIFIED) {
if(state & GDK_WINDOW_STATE_ICONIFIED) {
printf("iconified\n");
} else {
printf("deiconified\n");
}
}
return false;
}
