<descr>
<p>
<var>Move</var> ensures that the current tree node selected on the filtered
edit control is saved and restored after the node has is moved to its new
position. The Move method in the original Items data (TStrings) is called to
relocate the content to the position in NewIndex. InvalidateBranch is called
to sort and filter the tree nodes and their data, and to update the filtered
tree edit and its associated tree view control.
<var>Move</var> is a method used to change the ordinal position for a tree node and its associated data in the root node for the branch.
</p>
<p>
CurIndex contains the ordinal position for the tree node relocated in the
method.
</p>
<p>
NewIndex contains the new ordinal position for the tree node.
</p>
<p>
Move changes the value in the Index property for the TTreeNode instance to
NewIndex to reorder the tree node in the branch. It also moves data for the
tree node supplied by the caller using the specified ordinal positions.
</p>
<p>
Move calls the MakeVisible method in the TTreeNode instance to ensure that it
is visible on the Tree View control (when assigned). If the Tree View control
is not assigned, the parent nodes for the tree node are expanded to make the
node visible in the tree.
</p>
</descr>
<version>
Modified in LCL 2.2.6 to save and restore the current tree node selected in
the owner tree view control.
