[gtk-list] Moving the focus within a GtkCTree

[DataWare Technology Pty. Ltd.]

Hi,   Any pointers would be welcome.   I'm trying to invoke a moving of the "focus" not "selection" within a GtkCTree by means of a button.  That is, by depressing an "Up" or "Down" button widget, I am able to move the "focus" up or down a fully populated GtKCTree.   Got any ideas?  I've probably overlooked a really simple solution...   Cheers,   Frank [EMAIL PROTECTED]
