37 This is a button that when pushed pops up a menu (or hierarchy of
38 menus) defined by an array of
40 <P ALIGN=CENTER>\image html menu_button.png</P>
41 \image latex menu_button.png " menu_button" width=5cm
42 <P>Normally any mouse button will pop up a menu and it is lined up
43 below the button as shown in the picture. However an Fl_Menu_Button
44 may also control a pop-up menu. This is done by setting the type().
45 If type() is zero a normal menu button is produced.
46 If it is nonzero then this is a pop-up menu. The bits in type() indicate
47 what mouse buttons pop up the menu (see Fl_Menu_Button::popup_buttons). </P>
48 <P>The menu will also pop up in response to shortcuts indicated by
49 putting a '&' character in the label(). </P>
50 <P>Typing the shortcut() of any of the menu items will cause
51 callbacks exactly the same as when you pick the item with the mouse.
52 The '&' character in menu item names are only looked at when the menu is
53 popped up, however. </P>
54 <P>When the user picks an item off the menu, the item's callback is
55 done with the menu_button as the Fl_Widget* argument. If the
56 item does not have a callback the menu_button's callback is done
