/** |
|
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 ALIGN=CENTER>\image html menu_button.gif</P> |
|
\image latex menu_button.eps " menu_button" width=5cm |
|
<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() |
|
, see below. </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. |
