Re: regarding animated mng support in gtk for directfb
Hi, I am using GTK-2.12.12. I have compiled mng lib from http://sourceforge.net/projects/libmng/ . The test application, I have used for X11 with linux.mng is at libmng-1.0.10/contrib/gcc/gtm-mng-view . gtk-mng-view is a sample gtk based application to view mng. I could able to see linux.mng with animation effect. But when I try to run the same source code(gtk-mng-view) for GTK/DirectFB only 1st frame it shows.

It actually is difficult, because libmng doesn't expose its functionality in a way that easily maps to GdkPixbufAnimation/GdkPixbufAnimationIter. ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
Re: Fwd: regarding animated mng support in gtk for directfb
Also, you could write a GdkPixbufLoader plugin, so that all GTK+ apps
can view MNGs. It shouldn't be too difficult.

I've had a look at this and the problem is clearly in the gtk-mng-view
code. The example code there draws outside the expose handler. This is
something that you should never do. It may work for GTK-X11 if you are
lucky, but it's not supported and it definitely does not work if you
using the DirectFB backend. Simply replace the function
mng_refresh_callback() in gtk-mng-view.c with the following code and it
will work just fine:
static mng_bool
mng_refresh_callback (mng_handle mng_h,
mng_uint32 x,
mng_uint32 y,
mng_uint32 width,
mng_uint32 height)
{
gtk_widget_queue_draw_area (GTK_WIDGET (mng_get_userdata (mng_h)),
x, y, width, height);
return MNG_TRUE;
}

If you could provide the code together with a test case, I might find time to check if I can reproduce your problem and perhaps find out what's going wrong. What version of GTK+ are you using?

regarding animated mng support in gtk for directfb
Hi, Iam trying to give support for animated mng on gtk-directfb. Animated mng file is working fine with gtk-x11 background but with gtk-directfb background it loads only one frame of mng file. Can you help me regarding this. or Do you have any more information which you can share.
