TCustomTreeView.WndProc Method

Provides specific message responses for the control.

Pascal
procedure WndProc(var Message: TMessage); override;
C++
virtual __fastcall WndProc(TMessage Message);

WndProc is the initial Windows message handler for the control. The WindowProc property is initialized to point to the WndProc method. 

WndProc adjusts for some Windows message idiosyncrasies before calling the WndProc method inherited from TWinControl
