Description

Allows you to respond to changes in the checkbox state of a tree node, which is typically used for multi-selection or hierarchical selection scenarios.

Parameters

• Sender: The object that triggered the event. This is usually the TTreeViewItem whose checked state changed, not the TTreeView control itself. As such, the type is typically TTreeViewItem.
• Node: The specific tree node whose checked state was changed.
• NewChecked: The new checked state (True or False).
