Re: How to draw GtkImage in runtime?

["Dov Grobgeld" <dov grobgeld gmail com>]

Just use gtk_image_set_from_pixbuf() which allows you to set and/or update the pixbuf displayed by a GtkImage .

I need to draw several tool buttons with colored circles and rectangles on them.
I thought of doing something like:
----------
GtkToolItems *color_buttons[COUNT_OF_COLORS];
GtkWidgets *color_icons[COUNT_OF_COLORS];
GdkColors colors[COUNT_OF_COLORS] = {.....};
..... /// here is initialization of tool buttons
for( i = 0; i<COUNT_OF_COLORS; i++) {
      GdkPixbuf *icon = gdk_pixbuf_new(GDK_COLORSPACE_RGB, TRUE, 8, 40, 40);
      GdkDrawable *dicon = ????
      //// how to get GdkDrawable from GdkPixbuf???
      GdkGC *gc = gdk_gc_new(dicon);
      gdk_gc_set_rgb_fg_color(gc, &(colors[i]));
      gdk_draw_rectangle(dicon, gc, TRUE, 2, 2, 36, 36);
      color_icons[i] = gtk_image_new_from_pixbuf(icon);
      g_object_unref(G_OBJECT(dicon));
      g_object_unref(G_OBJECT(icon));
      g_object_unref(G_OBJECT(gc));
      gtk_tool_button_set_icon_widget(GTK_TOOL_BUTTON(color_buttons[i]), color_icons[i]);
}
------------
And I am stuck on converting GdkPixbuf to GdkDrawable...

What is the easiest way to make a brand new GtkImage and draw something on it in runtime?
