Tristan, (it feels really weird addressing an email to "Tristan" as I've

You have to start somewhere :) Im 29 yrs old and Ive met about 4.

[...]

glade-3 now says (upon adding my widget to a toplevel !YAY!):

**
** Gtk:ERROR:(/build/buildd/gtk
+2.0-2.12.9/gtk/gtkwidget.c:7967):gtk_widget_real_realize: assertion
failed: (GTK_WIDGET_NO_WINDOW (widget))
Aborted


Please tell me that your widget already works and that your
not making your tests in an experimental glade environment :D

Just have to double check ;-)

What does "/gtk/gtkwidget.c:7967):gtk_widget_real_realize()" have to
say about it, did you look at the source around the assertion ?

I think your widget may try to create a widget->window when you
didnt unset the GTK_WIDGET_NO_WINDOW flag in your init()
routine, something like that.

Cheers,

Then I wrote a catalog xml file below which I copied

I meant /usr/lib/glade3/modules

It seems if I put libc.so.6 into modules as libc.so and change the
catalog file to library="c" then libc gets loaded. This is a bit odd
because I'm sure the libc authors didn't do anything special to make
libc loadable from glade.
