object

A SftTreeItems object.

Preserve

Defines whether the expand/collapse state is restored. This argument is ignored if the Depth argument is True.

Preserve	Description
True	Restores the expand/collapse state of dependent items made visible, as saved by a previous call to Items.Collapse or Item.Collapse.
False	The expand/collapse state is not restored. All items are expanded and immediate dependents are made visible. They may be expanded or collapsed based on the Depth argument.

Depth

Defines the depth of the items to become visible.

Depth	Description
True	Expands all dependent items, including non-immediate dependent items. Preserve is ignored as all dependents are expanded.
False	Expands dependent items, based on the Preserve settings.

Comments

The Expand method expands all items so their dependents become visible.

The Expand method expands all items and restores the expand/collapse state of all dependent items, as saved by a previous Items.Collapse or Item.Collapse method call. The Expand method visits each item on level 0 and expands these based on the Preserve and Depth arguments.

If items are already expanded when using Expand, the items remains unchanged. It does not make any indirect dependents visible. To make sure that an item's indirect dependents are shown, use the Items.Collapse method first, which collapses all items (and all dependents), followed by Expand. Now all dependents are visible.
