TControl.ClientToParent Method
|
RAD Studio VCL Reference
|
|
|
Translates client coordinates to parent coordinates.
function ClientToParent(const Point: TPoint; AParent: TWinControl = nil): TPoint;
__fastcall TPoint ClientToParent(const TPoint Point, TWinControl * AParent = nil);
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++).
