object

A SftTree object.

Boolean

Defines whether the tree control is in virtual mode.

Boolean	Description
True	The tree control is in virtual mode.
False	The tree control is not in virtual mode.

Comments

The VirtualMode property defines whether the tree control is in virtual mode.

In virtual mode, the tree control can be used to display flat lists (without hierarchy) with up to 2,000,000,000 items.

If virtual mode is used, graphics, colors and all tree control data and attributes are provided by the VirtualItem event, which the application must implement to use a virtual data source. This eliminates lengthy initialization when many items are to be displayed.
