Perhaps you are using the wrong version of gtk-config? Do a "which gtk-config" and make sure it corresponds with the one you want to use. My guess would be that glib-1.2 is installed in /opt/sfw and glib-2.2 is installed in /usr/local, so you would want to use /usr/local/bin/gtk-config instead of /opt/sfw/bin/gtk-config.

Below is the example scribble program modified to use blue instead of
black.
> How can I use specific RGB values such as RGB(128, 32, 41)?
I use something like this:
void
color_foreground_set(int red, int green, int blue)
{
color_fg.red = red * 255;
color_fg.green = green * 255;
color_fg.blue = blue * 255;
gdk_color_alloc(colormap, &color_fg);
gdk_gc_set_foreground(gc, &color_fg);
}
So all you would have to do is call like this:
color_foreground_set(128, 32, 41);
Hope this helps,
Chris

Here is a small demo of how to display an image using Gtk+ 1.x and Imlib.
I ended up using gdk-pixbuf instead, but do not have a handy demo program
of that.

You draw the pixmap in the expose event:
gint expose_event( GtkWidget *widget,
GdkEventExpose *event )
{
GdkPixmap *pixmap;
pixmap = pixmap_get();
gdk_draw_pixmap(widget->window,
widget->style->fg_gc[GTK_WIDGET_STATE (widget)],
pixmap,
event->area.x, event->area.y,
event->area.x, event->area.y,
event->area.width, event->area.height);
return FALSE;
}
You can use the gdk_draw_string to get text to the pixmap:
gdk_draw_string(pixmap, font, gc, x, y, s);
And you can use the gtk_wdiget_queue_draw() function to emit an expose
signal:
gtk_widget_queue_draw(w);
Hope that helps.
