MoveRight is a method used to change the selected tree node on the control by moving towards the right (or downwards) in the node hierarchy. The action normally results in the next expanded sibling or child node becoming the selected tree node.
The behavior in MoveRight is influenced by the settings in the Options property and the value in the ASelect argument.
ASelect indicates whether the new node becomes a Selected node on the tree view control (when True) or simply has the focus rectangle (when False).
If multi-selections are enabled in Options (using tvoAllowMultiSelect), the movement starts from the last node in the multi-selection range. Otherwise the Selected node is used to start the movement.
Prior to changing the active node, the node must be in the Expanded state. When not enabled, Expanded is set to True but the Selected node does not change. If Expanded is already enabled, the GetNextExpanded method is called to get the target node for the movement. The MoveSelection method is called to change to the specified node and set its Selected (or MultiSelected) attributes to the value in ASelect.
MoveRight is used in the KeyDown method for the control.
Added in LCL version 3.0.
