Thanks for your patient.
But in the "whiz-bang tutorial" you mentioned, I can't find answer of my questions.
I'll try harder. Thanks again.

If you look in gtk+-yourversion/docs/reference/gtk/html
you see gtk-Signals.html.
Search thru the files in that subdir for any keyword you want.
GtkColorSelection.html has info on gdk_color_parse.
This is from /tests/testgtk.c
GdkColor red;
/* make the widgets */
button = gtk_button_new_with_label ("A Button");
event = gtk_event_box_new ();
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (window, "destroy",
G_CALLBACK (gtk_widget_destroyed),
&window);
/* put a red background on the window */
gdk_color_parse ("red", &red);
gtk_widget_modify_bg (window, GTK_STATE_NORMAL, &red);
/* set the colourmap for the event box.
* must be done before the event box is realised.
*/
screen = gtk_widget_get_screen (event);
rgba = gdk_screen_get_rgba_colormap (screen);
gtk_widget_set_colormap (event, rgba);
In Perl, this is what we use for named colors:
######################
my $gc = Gtk2::Gdk::GC->new ($gdkwindow, undef);
my $colormap = Gtk2::Gdk::Colormap->get_system;
$colormap = $gc->get_colormap;
# draw a pink rectangle
my $color = Gtk2::Gdk::Color->parse('pink');
my $colormap = $gdkwindow->get_colormap;
$colormap->alloc_color($color,TRUE,TRUE);
Gtk2::Gdk::GC::set_foreground($gc, $color);
#######################
You are not going to find 1 whiz-bang tutorial that explains everything
in full simplicity. You need to read the docs, search for examples of the keywords,
and piece it together yourself.
Searching thru this maillist archives will also yield many code examples.
