Hi there,
I have a simple dialog box containing three popupmenus. I would like the =
data to be displayed in each to be conditional on what is chosen in the =
previous popupmenu. How do I achieve this in MapBasic? Is it possible?
Using the Calling keyword I can launch a handler procedure, but within =
this, how can I access the current value of the popupmenu?. The variable =
identified by the Into clause only seems to be populated once the OK =
button is pressed which is not what I want.
Order of events:
1. popupMenu_1 is populated on intitialisation.
2. The user chooses an item from popumenu_1 which determines what =
populates popupmenu_2
3. The user chooses an item from popumenu_2 which determines what =
populates popupmenu_3
4. The user chooses an item from popumenu_3
5. The user clicks the Ok button to lauch an action.
Any ideas?
Regards,
Aine Deery
