TCustomTreeView.ChangeDelay Property

Specifies the delay between when a node is selected and when the OnChange event occurs.

Pascal
property ChangeDelay: Integer;
C++
__property int ChangeDelay;

Use ChangeDelay to get or set the delay, in milliseconds, between when a node is selected and when the OnChange event occurs. 

Set the ChangeDelay to 50 milliseconds to emulate the behavior of the tree-view control used in Windows Explorer.
