Detailed Description

Gadget class.

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.

IlvAbstractBar, IlvMenuItem, IlvOptionMenu, IlvComboBox.

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues().
