Declaration
procedure MoveSelection(ANewNode: TTreeNode; ASelect: Boolean)Arguments
ANewNode | Tree node to select in the control. |
ASelect | True to include the tree node in Selections (when enabled), False to select only the specified node. |
Description
MoveSelection is a method used to make the tree node in
ANewNode a selected node in the tree view control. The actions
performed depend on the multi-selection setting for the control. When
tvoAllowMultiSelect has been included in the
Options
property, the node is included in
Selections when
ASelect is
True.
If multi-selection has not been enabled for the control, the value in
ANewNode is assigned to the Selected property.
The MakeVisible method in the TTreeNode instance is
called to make the node visible, and the scroll bars for the control are
updated.
Used in the implementation of the KeyDown method. Used to
implement methods like MoveHome, MoveEnd,
MovePageDown, MovePageUp, MoveToNextNode,
and MoveToPrevNode.
