DESCRIPTION

This class is a Tk::Multi::Manager packed in a Toplevel window. It features also :

• 'File->show internal...' button to invoke an Object Scanner (See Tk::ObjScanner)

• A facility to manage user menus with sorted buttons

• A help facility based on Tk::Pod

Users menus

By default the Multi::Toplevel widget comes with 3 menubuttons:

• 'File' for the main widget commands

• 'windows' to manage the Multi slaves widget

• 'Help'

The user can also add its own menus and menu buttons to the main menubar. When needed the user can call the menuCommand method to add a new menu button (and as new menu if necessary) . Then the user can remove the menu button with the menuRemove command.

For instance, if the user call :

 $widget->->menuCommand(name => 'foo', menu => 'example', 
   sub => \&a_sub);
  

The menubar will feature a new 'example' menu with a 'foo' button.

Then if the user call :

 $widget->->menuCommand(name => 'bar', menu => 'example', 
   sub => \&a_sub);

The menubar will feature a new 'bar' button in the 'example' menu. Note that menu buttons are sorted alphabetically.

Then if the user call :

 $widget->menuRemove(name => 'bar', menu => 'example');

The bar button will be removed from the menu bar.
