Detailed Description

Menu item class.

Library: ilvgadgt

The class IlvMenuItem implements the items appearing in pop-up menus (IlvPopupMenu) or in menu bars (IlvMenuBar, IlvToolBar). A menu item can display a label, a bitmap, a graphic object and can be used as a separator.

See also: IlvAbstractMenu, IlvPopupMenu, IlvAbstractBar, IlvToolBar, IlvMenuBar.

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(). This class inherits the accessors of its superclass IlvGadgetItem and adds the following ones:

Name	Type	Equivalent methods
`type`	Int	`getType()`
`checkedBitmap`	Bitmap	`getBitmap(const IlSymbol*) const`, `setBitmap()`
`checked`	Boolean	`isChecked()`, `setChecked()`

Note: A radio toggle appears as a diamond under Motif and as a circle under Windows/Windows 95/ViewsX.

See also: setRadioToggle(), IlvPopupMenu.

§ isReadOnly()

IlBoolean IlvMenuItem::isReadOnly ( ) const

Indicates whether the menu item is read-only.
