Gtk+ is double buffered (at GDK level), see federico's great doc: http://primates.ximian.com/~federico/misc/gtk-drawing-model/index.html cheers -- Gian Mario Tagliaretti http://www.parafernalia.org/pygtk/ ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Double Buffering
I tried searching the mailing list but the search seems to still be down from July... I'm looking to do some double buffered 2D animation in a GTK application. What is the best way to go about this? Are there double buffered GTK widgets or would I be better off using OpenGL or some other libraries? Thanks for any help. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
How can I disable double-buffering? or How can I draw in a drawable immediately?
I am trying to write a function that draws stuff in a
drawingarea immediately.
I want the images to be drawn directly when I call the
function.
What I am trying to make is something like this:
void main_function(...) //called directly after
program start
{...
My_drawing_function(...);
//the image displayed in the drawingarea has changed
getchar();
...
//exit program
}
I figured the problem comes from the double-buffering
and I tried to disable it using:
GTK_WIDGET_UNSET_FLAGS (window1,GTK_DOUBLE_BUFFERED);
But it didn't work.
So how can I disable double-buffering?
Or if the problem is coming from something else, where
is it?

Zoidberg

Does double buffering work on Microsoft Windows?
Does double buffering work on Microsoft Windows? I'm developing an application with rather complicated interface which require a lot of switching of GtkNotebook pages. I've designed this interface in Glade and use libglademm and gtkmm (C++). On my Fedora Core 4 Linux using GTK+ 2.6.10 and GTKmm 2.6.2 there is no flicker when swithing notebook pages. On Windows XP Professional using GTK+ 2.8.6 from http://gladewin32.sourceforge.net/ and GTKmm 2.8.1 from http://www.pcpm.ucl.ac.be/~gustin/win32_ports/ there is a lot of flicker when I switch pages - I can almost see how pages are build. I've checked if my window does have double buffering set - it has. According to documentation this is by default. So why flicker?

Double Buffering
Hi i was wanting to highlight a portion of an image just by clicking and dragging over it. When i drew directly on the image there was a lot of flickering. So now i always draw to a offscreen pixmap and then display that pixmap. It works nicely and there is no flickering. The problem is that i draw and show the pixmap on motion_notify event and hence for large pictures like 600 * 400 my system starts to go really slow and it looks awfull. Could anyone please help me out.
