Re: [platform-swt-dev] GTK in CVS

[Steve_Northover@xxxxxxx]

Must be fixed in 2.0.  I just compiled and ran the program and here is the output:

HA-HA-HA
HA-HA-HA
g_log_remove_handler(): could not find handler with id `2' for domain "GLib"

Gtk-CRITICAL **: file gtkwidget.c: line 1424 (gtk_widget_show): assertion `widget != NULL' failed.

GLib-CRITICAL **: file gstring.c: line 279 (g_string_truncate): assertion `string != NULL' failed.

The appended program works for me. I'm not sure what's wrong.

Feel free to ask me if you feel like you're stuck after fooling around
with something for a while and checking the docs. There's also
gtk-list if you want to ask a wider audience (sometimes you can get a
faster answer, or even someone who knows stuff I don't ;-)

Another resource is bugzilla.gnome.org - anytime you're working around
GTK or have suggestions, or just find it not working, bug reports are
appreciated. Test cases are good if you have them, but not required.
