Constructor & Destructor Documentation

IlvMenuBar::IlvMenuBar	(	IlvDisplay *	display,
		const IlvPoint &	point,
		const char *const *	labels = 0,
		IlUShort	count = 0,
		IlUShort	thickness = IlvDefaultGadgetThickness,
		IlvPalette *	palette = 0
	)

Constructor.

Initializes a new instance of the IlvMenuBar class. The size of the object is computed by calling the IlvGadget::fitToContents method. If you want the menu bar to have a specific size, use a constructor that takes an IlvRect reference instead of an IlvPoint object as parameter. The labels are copied.

Parameters:

	display	The connection to the display.
	point	The position of the menu bar.
	labels	An array of predefined labels.
	count	The number of elements in the labels array.
	thickness	The thickness of the menu bar.
	palette	The palette used to draw the menu bar.

IlvMenuBar::IlvMenuBar	(	IlvDisplay *	display,
		const IlvRect &	rect,
		const char *const *	labels = 0,
		IlUShort	count = 0,
		IlUShort	thickness = IlvDefaultGadgetThickness,
		IlvPalette *	palette = 0
	)

Constructor.

Initializes a new instance of the IlvMenuBar class. The labels are copied.

Parameters:

	display	The connection to the display.
	rect	The size and position of the menu bar.
	labels	An array of predefined labels.
	count	The number of elements in the labels array.
	thickness	The thickness of the menu bar.
	palette	The palette used to draw the menu bar.

IlvMenuBar::IlvMenuBar	(	IlvDisplay *	display,
		const IlvPoint &	point,
		IlvMenuItem *	items,
		IlUShort	count,
		IlUShort	thickness = IlvDefaultGadgetThickness,
		IlvPalette *	palette = 0
	)

Constructor.

Initializes a new instance of the IlvMenuBar class. The size of the object is computed by calling the IlvGadget::fitToContents method. If you want to give the menu bar a specific size, use a constructor that takes an IlvRect reference instead of an IlvPoint object as parameter. The items are copied.

Parameters:

	display	The connection to the display.
	point	The position of the menu bar.
	items	An array of predefined items.
	count	The number of elements in the items array.
	thickness	The thickness of the menu bar.
	palette	The palette used to draw the menu bar.

IlvMenuBar::IlvMenuBar	(	IlvDisplay *	display,
		const IlvRect &	rect,
		IlvMenuItem *	items,
		IlUShort	count,
		IlUShort	thickness = IlvDefaultGadgetThickness,
		IlvPalette *	palette = 0
	)

Constructor.

Initializes a new instance of the IlvMenuBar class. The items are copied.

Parameters:

	display	The display connection.
	rect	The size and position of the menu bar.
	items	An array of predefined items.
	count	The number of elements in the items array.
	thickness	The thickness of the menu bar.
	palette	The palette used by the menu bar.

Member Function Documentation

virtual void IlvMenuBar::drawGadgetItem	(	const IlvGadgetItem *	item,
		IlvPort *	port,
		const IlvRect &	rect,
		const IlvTransformer *	t = 0,
		const IlvRegion *	clip = 0
	)			const [virtual]

Draws a specific gadget item.

Redraws item in port at the location specified by rect using the clipping area clip. This method simply calls IlvGadgetItem::draw using the item instance.

Parameters:

	item	The item to be redrawn.
	port	The destination drawing port.
	rect	The bounding box of the item.
	t	The transformer used to draw the item. Not used.
	clip	The clipping area.

IlvGadgetItem::draw.

void IlvMenuBar::internalBBox	(	IlvRect &	rect,
		const IlvTransformer *	t = 0
	)			const [virtual]

Returns the internal bounding box of the bar.

Uses rect to return the internal bounding box of the bar when the object is computed with the transformer t. The internal bounding box delimits the area within which the bar items are drawn. You can override this member function in a subclass to change the internal bounding box.

Parameters:

	rect	The internal bounding box of the bar.
	t	The transformer used to compute the internal bounding box.
