Declaration

Description
MultiSelect is a method used add nodes to the internal selection
list relative to the node specified in
Node. MultiSelect uses
values in the
MultiSelectStyle property for the tree view control
in
Owner to determine the nodes added. Specifically:
- msSiblingOnly
- When present, only sibling nodes are selected for the specified node. When omitted, child nodes are added to the multi-selection.
- msVisibleOnly
- When present, only visible nodes are included in the multi-selection. When omitted, all nodes are eligible regardless of their visibility.
ClearWholeSelection indicates whether all existing nodes in the
multi-selection are cleared before added new node(s) to the selection list.
When set to
True, the
ClearMultiSelection method is called.
Otherwise, the last node in the selection list is removed.
Nodes in the internal selection list are visited to set their
MultiSelected property to True. Members used to track the
first and last nodes in the multi-selection are updated prior to exit.
