[Gambas-user] Menus

[Gianni Piccini]

Anybody knows if there is a method to check if enable or disable menus when
clicking top level menu? I mean that, if I've a menu like this

File
  Open
  Close
  Exit
  
for example I would like to have Close enabled only if something is open...
there are some others situations where I can disable menus, but certainly
the top level menu is the last and most secure (and surely the most
professional). Obviously, inserting a condition in MenuFile_Click() doesn't
work.
