I have a large IDL application for which I would like to set
up a menu interface. I would like to have 5-10 menu buttons with
pulldown menus, hence I'm using 'xpdmenu'. Each menu button is
registered using 'xmanager' and has an 'event_handler' routine. Each
menu button has a parent menu and each parent menu has some items that
have submenus. (I'm not sure yet if I can register each menu button
separately, but let's assume I can).
My problem occurs with the submenus that I have for some of
the menu selections. What I would like to do is have a different
routine to handle events from a submenu. I don't want to use the same
routine as registered with the 'event_handler' for the parent menu.
Is there any way that I can call a different 'event_handler' routine
if an item from a submenu is selected ?
The reason why I want to do this is because the submenu items
perform tasks that are distinct from the tasks performed by the items
in the main menu. I really don't want to have a huge case statement
in only one 'event_handler' routine that is forced to handle every
item from the parent menu and every item from each of its submenus.
I've thought about having no submenus, but that would result
in a cluttered menu base with a whole bunch of menu buttons.
