Member Function Documentation

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

Returns a new gadget item.

You can override this member function in a subclass to create your own gadget items, however your subclass of gadget item must inherit from IlvTreePathGadgetItem.

Parameters:

	label	The item label.
	graphic	The IlvGraphic object representing the picture associated with the item.
	bitmap	The IlvBitmap object representing the picture associated with the item.
	selbitmap	The IlvBitmap object representing the picture of the item when it is selected.
	copy	A Boolean value specifying whether a label should be copied. If the value is IlFalse, then memory must be allocated for the label because the label characters are deleted from memory by the IlvGadgetItem.

Warning:

[note] If the second and third parameters are both not null, only the second parameter is used.

Returns:

The created gadget item.
