I have a pop-up menu that lists categories of things users can

done that,
the dialog closes and the requested items are shown in a list.
My problem is, if the user selects the same category again (because
they
want to see different items), I don't get any action event from the
popup
menu because its value hasn't changed. In both Visual Basic and
FutureBasic,
I simply respond to a popup menu action event and get its value,
but there
doesn't seem to be anything except the Change event in RB.
So the question is, how can I tell when a user has made a *repeat*
selection
from a popup menu?
You could set ListIndex to -1 when your dialog closes. That will
"clear" the popup of any selection, putting it back to an initial
state. Now any selection, even a repeat, will fire the Change event.
If you are using ShowModal for opening your dialog from your main
window just do:
MyDialogWindow.ShowModal // shows dialog
self.PopUpMenu1.ListIndex = -1 // executes when dialog closes or hides
If you are not using ShowModal, just put the following in the Close
event of the dialog:
MyMainWindow.PopUpMenu1.ListIndex = -1 // be wary of implicit
instantiaton
Or is there a better control for what I'm doing?
A listbox is certainly an option.
HTH,
