Description
Translates client coordinates to parent coordinates.
ClientToParent translates Point from the current control's coordinate system to AParent's coordinate system. AParent must be a control that can be found by iterating up the chain of Parent properties. If AParent is nil (Delphi) or NULL (C++), the control's immediate parent is used.
An EInvalidOperation exception is thrown if AParent is not an ancestor control or the Parent property is nil (Delphi) or NULL (C++).
