Detailed Description

Gadget Class.

Library: ilvadvgdt

The IlvHierarchicalSheet class implements a special sheet that handles a tree hierarchy. The tree is composed of objects of the class IlvTreeGadgetItem, and can be accessed through the same API as the IlvTreeGadget class. By default, the tree hierarchy is drawn in the first column of the sheet, but you can change this setting by overriding the member function getTreeColumn.

void IlvHierarchicalSheet::addItem	(	IlvTreeGadgetItem *	parent,
		IlvTreeGadgetItem *	item,
		IlInt	index = `-1`
	)

Adds the specified item to the tree hierarchy.

When a tree item is added to the sheet, the associated row is automatically created and the sheet is redrawn.

Parameters

parent	The parent of the added item. If parent is `0` , the new item is added to the root item.
item	The item to be added.
index	The position where the new item should be added in the list of child items. If index is `-1`, the item is added at the end of the list.

See Also: removeItem, addItem(IlvTreeGadgetItem*, const char*, IlInt, IlvBitmap*, IlvBitmap*)

IlvTreeGadgetItem* IlvHierarchicalSheet::addItem	(	IlvTreeGadgetItem *	parent,

		IlInt	index = `-1`,
		IlvBitmap *	bitmap = `0`,
		IlvBitmap *	selectionBitmap = `0`
	)

Adds an item to the tree hierarchy with the specified label.

When a tree item is added to the sheet, the associated row is created automatically and the sheet is redrawn.

Parameters

parent	The parent of the added item. If parent is `0` , the new item is added to the root item.
label	The label of the item to be added.
index	The position where the new item should be added in the list of child items. If index is `-1`, the item is added at the end of the list.
bitmap	The sensitive bitmap associated with the added item. The bitmap is locked.
selectionBitmap	The selection bitmap associated with the added item. The bitmap is locked.
