IMHO, this is completely the wrong way to write a GUI. In particular:
>~ while(showWindow) {
>~ pthread_mutex_lock(&drawing);
>~ if(showWindow) {
>~ gtk_main_iteration_do(FALSE);
>~ }
>~ pthread_mutex_unlock(&drawing);
>~ usleep(10000);
>~ }
that is an unacceptable main event loop. A GUI is an event loop that
needs to be driven by arriving events from the input devices and the
display. it is not a programmatic loop run according to internal
program logic.
