First of all, a general comment:

Please be careful when making blanket assertions like this. Its
apparent that you don't fully understand the signal/event handling
process, and thats not necessarily your fault - the mechanism in GTK+
1.2 is quite hard to understand and the documentation can be a little
misleading.

But not fully understanding something is not the basis for saying that
"its rough around the edges". Poor or inadequate documentation,
maybe. I am fairly familiar with both systems, and I can assure you
the GTK+ one is a lot more flexible and elegant than the system in
Motif once you understand it. Its also the case that some widgets have
been implemented in ways that interfere with the elegance of the
overall system. This isn't a comment on GTK+ signal handling, its a
comment on the implementation of a certain widget. GtkCombo is a
particular egregious example in this regard.

OK, back to the main issue:

this sounds an issue with the implementation of GtkSheet. I have
certainly performed this trick with GtkCList and GtkCTree and it has
worked like a charm.
