Hello Gtk gurus,
I have an X Display and an X Pixmap associated with that display, both
provided by a third-party library. I'd like to use the Pixmap in a GTK
program by wrapping it into a GdkPixmap structure. More specifically, i want
to use GTK's style functions (like gtk_paint_box) to draw to my Pixmap.
gdk_pixmap_foreign_new() should be what you're looking for.
How do i do that? I guess i need to convert X Display into a GdkDisplay
first -- how? gdk_x11_lookup_xdisplay() gives me NULL -- is that correct?
Use the macros, I think there is one of the form GDK_WINDOW_XDISPLAY().
You should find all of this in the xlib interaction section of the GDK
api reference manual.
Cheers,
-Tristan
