menu

[akpr]

I created a menu. How do I pass a reference to that menu to another function
i.e. I have a menu as follows
File
new
open
save
I want to disable the Save menu as soon as the menu is clicked.

To "pass a reference to [ignore][a][/ignore] menu" just pass the name of the menu widget. Then you can execute any of the menu operations described in the documentation. For example, let's assume that you've created the menu described above as follows:

. configure -menu .mbar

menu .mbar
.mbar add cascade -label "File"     -underline 0 -menu .mbar.file

menu .mbar.file
.mbar.file add command -label "New"     -underline 0 -command {}
.mbar.file add command -label "Open"     -underline 0 -command {}
.mbar.file add command -label "Save"     -underline 0 -command {}

Now, to programmatically interact with your File menu from elsewhere in your application, simply use execute an operation on your [tt].mbar.file[/tt] widget. For example, to disable your "Save" menu item:

.mbar.file entryconfigure "Save" -state disabled

To reactivate it:

.mbar.file entryconfigure "Save" -state normal

To programmatically invoke the "Save" command:

.mbar.file invoke "Save"
