Re: signals to catch a change in a combobox

["Richard Warren" <rew primagraphics co uk>]

Olivier,

I connect to "unmap" on the combo->popwin which gives a signal when the
popup window disappears (which may or may not be because a new item was
selected - you need to check).

This field is supposedly private within the combo structure so is not an
ideal method but it's the best thing I could find.

If your combo->entry is editable directly (rather than just via the item
list like mine is) you'll also need to handle changes to that, possibly by
connecting to a combination of "changed" (although I think you'll get called
for every character typed), "activate" and/or "focus-out-event" depending on
when you want to know.

There really ought to be a more useful signal in the combo box widget but I
don't know what it is if it exists.

Richard.
