The problem you're experiencing may be due to the gtk+ mainloop not having enough time to execute your function every 400 ms. There's a speedup which may help switch the pixmaps in a timely manner. > This is the code troca_pixmap : [snip] > gdkpixmap = gdk_pixmap_create_from_xpm (NULL, &mask, NULL, pathname); [snip] The above line recreates the pixmap every time you call this function. This requires: 1) reading the pixmap data from disk, 2) creating a pixmap on the X server, and 3) copying the pixmap data to the X server. This is all fairly time consuming. If you're only flipping back and forth between a couple of pixmaps, it'll be much faster if you only create them once and flip back and forth between the cached data.
