There is a call to Gtk_New for "Mon_Dessin".

I will attach the .adb file with this mail. (Sorry if variables names
are not really explicit for you, I'm coding in french)

This sample program is based on the "scribble" program for the
structure.

The thing I want to do is to draw a line on my drawing area after the
Gtk_Window and Gtk_Drawing_Area has been configured and showed.

I want to do that by an event sent by the ADA code (and not by a click
elsewhere by example). That's why I'm trying to generate a configure
event after everything is done.

Maybe the way I want to achieve my goal is far away from a better method
to do that, I'm a really newbie in GTK (I have got a certain experience
of ADA anyway).

Thank you for any help.
