Is there > anyway to increase the time accuracy? motion events (and touch update events) are compressed on a per-frame basis, since it the correct thing to do for every class of applications *save* for drawing ones. for those, we have API to disable event compression on a per-GDK window basis: https://developer.gnome.org/gdk3/stable/gdk3-Windows.html#gdk-window-set-event-compression your application should benefit from this API. ciao, Emmanuele. -- http://www.bassi.io [@] ebassi [@gmail.com] _______________________________________________ gtk-list mailing list gtk-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-list
