If you're playing the sound via library - no swapping a command line - you should use a separate thread to play the sound. http://developer.gnome.org/doc/API/2.0/glib/glib-Threads.html In your case, as no communication between the thread and the main application this should be quite easy. Just change: void my_callback(GtkButton* button, gpointer user_data) { // play sound code. } To: gpointer my_playing_sound_proccess(gpointer data) { // play sound code. return 0; } void my_callback(GtkButton* button, gpointer user_data) { GThread *thread; GError *error = NULL; // this can be moved to main() if (!g_thread_supported ()) { g_thread_init (NULL); } thread = g_thread_create (my_playing_sound_proccess, user_data, // or whatever FALSE, &error); if( thread==NULL ) { g_print("Error %s", error->message); } } Regards. -- Iago Rubio _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
