Are you going for a WYSIWYG thing? I'm sure I can't help you much
there.
Another idea that occurs to me is creating a tiny, borderless pop-up
window over the label that contains a single editable widget. The
window and editable could be created afresh every time the user wants to
edit a label (and destroyed after) so it wouldn't take additional memory
per widget. Having it pop-up z-order-above the label/main-window would
avoid the resizing issue. You could have this little window return any
kind of text, perhaps pango markup (generated from parsed WYSIWYG
text?). Or, when the window is instantiated, hand it a reference to the
label being edited and have the update occur when the window closes or
in real-time. You might even attach a little formatting tool-bar to one
edge of this tiny window so people could easily mark portions of text
bold, italic, etc.. One of the nicest bits of this is that you wouldn't
have to create a new "label" widget at all and instead rely on the
GtkLabel's existing strengths. You'd just connect whatever signals of
the GtkLabel you need to begin the pop-up/editing.
One of the major challenges, I think, would be getting the user to
notice the tiny window and avoid confusion about what is going on; with
this tiny modal "dialog." The tab, enter and/or escape keys would need
to close the window. And, how would the user signal signal that s/he
wants to edit the label? Perhaps editing could begin when the user
gives an "editable label" the focus and presses Enter.
