Hi Christian, the problem only occurs when trying to call base.Render(...) from a child class of CellRendererText. If I do the same thing with CellRenderer, then it works! ?????
I really don't understand why this is giving problems. I found that someone else posted the same problem at http://lists.ximian.com/pipermail/gtk-sharp-list/2005-January/005301.html, but this was in 2005. I couldn't find a bug posted in bugzilla about it, so I would like to make sure that it really is a bug. I'm only allowed to use the released version, 2.01 for windows :-( any ideas? thanks Christian Hoff wrote: > > No idea what problem you're experiencing here; overriding Render in my > custom cell renderer(derived directly from Gtk.CellRenderer) worked. > Overriding Activate is known not to work, but I hopefully will get that > patch finished in my approaching holidays :-) . > > What version of Gtk# are you using?
