Member Function Documentation

void IlvAbstractMenu::addHighlightCallback	(	IlvGraphicCallback	callback,
		IlBoolean	submenus = IlTrue
	)

Adds a "Highlight" callback to the menu.

Adds the "Highlight" callback specified by callback to the menu. If submenus is set to IlTrue, the same callback is added to the submenus. When the callback is invoked, its IlAny parameter can be cast in a pointer to an IlShort. This IlShort indicates the position of the currently highlighted menu item or is set to -1 if no menu item is highlighted. See the example in the setHighlightCallback() method above. A "Highlight" callback is invoked when an item of the menu is highlighted.

Parameters

callback	A pointer to the callback.
submenus	Specifies whether the callback should be propagated to the submenus.

See also

setHighlightCallback().

void IlvAbstractMenu::addHighlightCallback	(	const IlSymbol *	callbackName,
		IlBoolean	submenus = IlTrue
	)

Adds a named "Highlight" callback to the menu.

Adds the highlight callback specified by callbackName to the menu. If submenus is set to IlTrue, the same callback name is added to the submenus. When the callback is invoked, its IlAny parameter can be cast in a pointer to an IlShort. This IlShort indicates the position of the currently highlighted menu item or is set to -1 if no menu item is highlighted. See the example in the setHighlightCallback() method above. A "Highlight" callback is invoked when a menu item is highlighted.

Parameters

callbackName	The name of the callback.
submenus	Specifies whether the callback should be propagated to the submenus.

See also

setHighlightCallback().

void IlvAbstractMenu::addItem	(	const IlvMenuItem &	item,
		IlShort	index = -1
	)

Inserts a copy of a menu item at the specified index.

Parameters

item	The menu item to copy and add.
index	The index where to add the item. If index is -1, the item is appended to the list.

virtual IlvGadgetItem* IlvAbstractMenu::createItem ( const char *  label, IlvGraphic *  graphic = 0, IlvBitmap *  bitmap = 0, IlvBitmap *  selbitmap = 0, IlBoolean  copy = IlTrue  ) const
