I can't figure out how to get notified when the user has
chosen an item from a drop-down combo-box.
If I use EVT_COMBOBOX, there is a continuous stream of events
that _stop_ when a choice has been made. That's pretty much
the opposite of what I want.
If I use EVT_TEXT, I also get notified when the user edits the
textbox (which I don't want). I can probably write code to
ignore the events I don't want to know about, but it seems very
counter-intuitive that I can't get an event when a choice has
been made.
i'm using EVT_COMBOBOX and the only events i get is when something
happens at the CB; are you sure you don't have your widget ref #'s mixed-up
or something?

That may be true for me as well, depending on your definition
of "something happens". As the mouse moves around within a
single selection item, there is a stream of events.
are you sure you don't have your widget ref #'s mixed-up or
something?
Hmm. Good question. I'm going to do some more experimenting.

Here's what I see. I press mouse button #1 on the little
arrow-box-button-thingy at the right end of the combo-box.
This causes a drop-down choice list to appear.
As I move the mouse pointer down over the list (with the button
still down), there is a continuous stream of events (even when
the mouse is stationary within one of the selections). The
output below was generated by pressing the mouse button to drop
the list down, moving the mose down to the third entry in the
drop-down list, and releasing the mouse button. It took
less than 1 second. Further experiments show that when holding
the mouse stationary, the events happen at 100 per second.

Grant,
just make a bare-bones simple frame with a combo box and callback
and check that you have the same behavior.

Ah, you don't release the mouse. I did, that's why I didn't see it. I don't know if this is correctable or not, but a "wxGTK specifc" bug report may help.

Oops. That should read 10 per second, not 100.

I'm going to try to put together a minimal program that
demonstrates the "bug" first.
