i'm afraid that's not what i really want. i will explain a bit more.
i wan't display some graphics within a GtkTable. for now:
[snip]
GtkWidget *gPix;
...
gPix = gtk_pixmap_new(pixmap1, mask1);
[snap]
and i insert gPix into the table. the pixmap is shown.

i just don't see how to use gtk_widget_shape_combine_mask
(which window to take) to solve this.

as i mentioned already i have two xpm-datas (pixmap1, pixmap2)
for now i draw pixmap2 onto pixmap1 and gPix is created from pixmap1.

i could imagine to go through the xpm-data by hand, merge the colormaps
and overwrite pixmap1 with all non-transparent-pixels from pixmap2.
but i think there must be something available doing this already.
(doing it even faster)

thanks in advance,
