Problem on gdk_window_shape_combine_mask and gtk_timeout
Hello, I use gdk_window_shape_combine_mask in gtk_timeout timer, to change my window's shape every second. While I first use gdk_window_shape_combine_mask without timer, it works. Then put it in the timer, the application crashed, with message: The program 'crazyclock.rb' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 181 error_code 8 request_code 128 minor_code 2) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Could someone help me out? Thanks. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: OpenGL, GtkGlArea, GtkGLExt
3 mar 2008 kl. 22.48 skrev Carlos Pereira: Hi Carlos, GtkGLext seems to be the most popular GL Area to use these days. You might also want to look at Clutter [1] or Pigment [2] which are canvases offering some higher level abstractions for 2D/3D usages. It depends a bit on what you need, if you just want an area for pure GL I'd go with GtkGLext. Regarding future inclusion of GL in GTK+ there is an open bug about it in the Bugzilla [3], I started looking into it a while back but didn't have time to get anything off my hard drive. There are some open issues in that you can read about in the bug tracker.

OpenGL, GtkGlArea, GtkGLExt
Hi, What is the currently recommended way to link GTK with OpenGL graphic areas? GtkGLarea? GtkGLext? other? What are the future plans for GTK regarding OpenGL? is GTK planning to support OpenGL directly without need for another library? I am not particularly interested in fancy arbitrary widget rendering with OpenGL, only rendering to graphic drawing areas, Best regards, Carlos ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

I don't think this way can work. To embed a X window in Gtk window, I
think you must handle the redraw event of the X window and manually
copy the drawables to the Gtk+ window.

Top/bottom margins for GtkTextView ?
Is there a way to set the top and bottom margins for text within the GtkTextView ? I've noticed there are methods to set the left and right margins, but not the ones for top and bottom.
