/**
|
|
This is a button that when pushed pops up a menu (or hierarchy of
|
|
menus) defined by an array of
|
|
Fl_Menu_Item objects.

|
|
<P>Normally any mouse button will pop up a menu and it is lined up
|
|
below the button as shown in the picture. However an Fl_Menu_Button
|
|
may also control a pop-up menu. This is done by setting the type().
|
|
If type() is zero a normal menu button is produced.
|
|
If it is nonzero then this is a pop-up menu. The bits in type() indicate
|
|
what mouse buttons pop up the menu (see Fl_Menu_Button::popup_buttons). </P>
|
|
<P>The menu will also pop up in response to shortcuts indicated by
|
|
putting a '&' character in the label(). </P>
|
|
<P>Typing the shortcut() of any of the menu items will cause
|
|
callbacks exactly the same as when you pick the item with the mouse.
|
|
The '&' character in menu item names are only looked at when the menu is
|
|
popped up, however. </P>
|
|
<P>When the user picks an item off the menu, the item's callback is
|
|
done with the menu_button as the Fl_Widget* argument. If the
|
|
item does not have a callback the menu_button's callback is done
|
|
instead.
