If it's got a little brawn, you can probably do everything you want to do through Cairo: http://cairographics.org (if your device is using a version of GTK+ 2.8 or newer). Based on the change of the rotation in your device, you could have it call the ::expose method on a GtkDrawingArea, and simply do whatever drawing in Cairo you wish from there. It's not incredibly powerful, but it's enough for simple animations and such, and it saves you from having to port over a huge canvas widget. If you're using an older version of GTK+, or your hardware doesn't have hardware floating point, performance might not be so hot through Cairo though, and you'll want to look at messing with GdkPixbufs. Hope that gets you started. Thank you. Regards, Konstantyn ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: Animation with GTK+
If you have an animated gif, you can use GtkImage. If you need to actually sync it with something external, you can use GdkPixbufAnimation and GdkPixbufAnimationIter: http://library.gnome.org/devel/gtk/unstable/GtkImage.html http://library.gnome.org/devel/gdk-pixbuf/unstable/gdk-pixbuf-animation.html - Original Message From: Prokopenko, Konstantyn [EMAIL PROTECTED] To: gtk-app-devel-list@gnome.org Sent: Wednesday, September 12, 2007 9:38:18 AM Subject: Animation with GTK+ Hello, I'm totally new to the GUI application development in Linux X11.
