TVirtualDrawTree.OnKeyAction Event
Miscellaneous event.
Pascal
property OnKeyAction: TVTKeyActionEvent;
Description
This event is a convinient way for the application or descentant trees to change the semantic of a certain key stroke. It is triggered when the user presses a key and allows either to process that key normally (leave DoDefault being True) or change it to another key instead (set DoDefault to False then). This way a key press can change its meaning or entirely be ignored (if CharCode is set to 0).
