pixmaps

["Brian Hanley" <brian hanley flextrade com>]

Hi All,

I would like to draw on a GdkPixmap, and place the pixmap in an GtkImage
widget.
Unfortunately, whenever I call "show" on the resulting image widget, I
get an
Xlib error.

I suspect it may be a colormap or GC problem, but am not sure.

I suppose I could use a GtkDrawingArea, but I'd prefer to avoid an
unnecessary
"expose" callback. Less complicated and more efficient to have a widget
that
knows how to redraw itself without my help.

Which colormap and GC should I be using?
What depths have to match up?

Is there a way to get a better error description than just X error code
8, "bad match"?

Tutorials/advice?
