Re: GnomeCanvas

The drawings are deleting each time you are moving an object over them. To
avoid the problem you have to connect your object (GnomeCanvas) to the
expose event. In this event you should be able to get the area which has
been destroyed, so you can redraw there what should be.
(there is a small example here :
http://www.editions-eyrolles.com/livres/odin/ - just download the zip file
(click on the link "fichier zip" - fichier stands for file...) And have a
look at the file DrawningArea.c in directory Chapitre17 (once you unzip the
file).

Hope this help,


Best regards,
