Ciao,
i use the mutex solution since tha fits well into the
existing code "). So, I have a thread that polls the
incoming queue in an endless loop:
while(1)
...
midi_callback()
}
and this function:
midi_callback(void)
{ ...
gdk_threads_enter ();
/* do the slider dance */
gdk_threads_leave ();
...
}
works and i am happy as the gui feedback is almost instant
now. ")
Cheers,
Jan
