This code does not work (program dumps a core) :


 GdkBitmap *mask = NULL;
 GdkPixmap *pdata = NULL;
 GtkStyle *style;

 style = gtk_widget_get_default_style();
 pdata = gdk_pixmap_create_from_xpm(draw->window, &mask,
&style->bg[GTK_STATE_NORMAL], xpm_file);

    gdk_window_shape_combine_mask(pdata, mask, 0, 0);

 pixm = gtk_pixmap_new(pdata, mask);

... a lot of pixmaps at the same time, in distinct positions and in the same
fixed ...




Thank you very much, Paul
