/**
|
|
Base class of all widgets that have a menu in FLTK.
|
|
Currently FLTK provides you with
|
|
Fl_Menu_Button, Fl_Menu_Bar, and Fl_Choice.
|
|
|
|
<P>The class contains a pointer to an array of structures of type Fl_Menu_Item. The
|
|
array may either be supplied directly by the user program, or it may
|
|
be "private": a dynamically allocated array managed by the Fl_Menu_.
|
|
|
|
When the user clicks a menu item, value() is set to that item
|
|
and then:
|
|
|
|
- If the Fl_Menu_Item has a callback set, that callback
|
|
is invoked with any userdata configured for it.
|
|
(The Fl_Menu_ widget's callback is NOT invoked.
|
|
|
|
- For any Fl_Menu_Items that \b don't have a callback set,
|
|
the Fl_Menu_ widget's callback is invoked with any userdata
|
|
configured for it. The callback can determine which item
|
|
was picked using value(), mvalue(), item_pathname(), etc.
