Re: GtkList

[Stephane Duguay <sduguay Matrox COM>]

Hi,

Mike, Thank you for your answer.

he main problem is that the "get text" method is NOT available with GtkList
(and I don't know why... damn !?!?).  If there was one, I could have figured
out a way to retrieve what I need.

Anyway, if anybody else have ever worked with GtkList the way i'm trying to,
please drop me a mail.

Have a good day,
Stephane.
