Handles the messages sent to a docksite

Declaration

Source position: controls.pp line 516

public procedure TDockManager.MessageHandler(

Sender: TControl;

var Message: TLMessage

); virtual;

This handler must handle all mouse messages, related to the client area of the docksite that is not covered by docked controls (dock headers...).

Handling mouse messages while dragging is not required. Painting of the docksite has to be implemented in PaintSite.
