Library: ilvgadgt
The IlvPopupMenu
class handles a list of menu entries laid out vertically. These menu entries, called menu items, are instances of the IlvMenuItem
class, which can store a label, a bitmap, or a graphic object of the class IlvGraphic
. A pop-up menu can be used as a submenu or as a standalone menu by calling the member functions IlvPopupMenu::show
or IlvPopupMenu::get
.
- IlvPopupMenu -
A pop-up menu can be torn off and put into a floating window. A tear-off pop-up menu can be detached by selecting the dashed line appearing across its top border. The first item of a tear-off pop-up menu must be of the type IlvTearOffItem
.
