Description

The IlvHierarchicalSheet class implements a special sheet that handles a tree hierarchy. The tree is composed of IlvTreeGadgetItem objects, and can be accessed through the same API as the IlvTreeGadget class.

Type Name Description Notes

IlvTreeGadgetItem addItem(IlvTreeGadgetItem parent, String label, Int index, Bitmap bitmap, Bitmap selectionBitmap) Adds the item item as a sub-item of the item parent. If parent is NULL, the new item is added to the root item. The parameter index indicates the required position for the new item in the list of child items. If index is -1 then the item is added at the end of the list.

Void expandItem(IlvTreeGadgetItem item) Expands the item to show the child items.

UInt indentation Sets and returns the indentation used in the tree hierarchy.

Void removeAllItems() Removes all the items from the tree hierarchy. All associated rows are removed from the sheet.

Void removeItem(IlvTreeGadgetItem item) Removes the specified tree item from the tree hierarchy. Associated rows are removed from the sheet.

IlvTreeGadgetItem root Returns the root item of the tree.

Void shrinkItem(IlvTreeGadgetItem item) Shrinks the item so that child items are no longer visible.

Boolean visibleLines Specifies whether connecting lines are drawn between parents and children (true) or not (false).
