In the past I've resisted making the GtkTreeView more like a sheet.  I
was hoping that someone would be able to do a separate sheet widget, as
it would be better suited to the task.  Unfortunately, it looks like
such a widget isn't forthcoming, and making a few changes so that the
TreeView can be used as a poor-man's sheet might be worthwhile.  It'd
probably okay to add a selection mode that's more spread-sheet like.  I
have no time to write it, so you'd have to implement it.  You should
probably send a proposed API/implementation here first.

You should be able to do that right now.  I think the combo renderer in
libegg actually uses this.

What do you mean?

Good luck,
