TControl.DoSetBounds procedure

Member of TControlprotectedIn unit Controls

Internal function used to set the bounds for the control (Left, Top, Height, Width).

Declaration

pascal

procedure DoSetBounds(ALeft: Integer; ATop: Integer; AWidth: Integer; 
 AHeight: Integer); virtual

Arguments

`ALeft`	Value applied to the Left member in the control.
`ATop`	Value applied to the Top member in the control.
`AWidth`	Value applied to the Width member in the control.
`AHeight`	Value applied to the Height member in the control.

Description

DoSetBounds is a low-level function used to set the private variables FLeft, FTop, FWidth, FHeight. Do not call this function; only the LCL calls it.

It also updates FClientWidth and FClientHeight accordingly.

Override this to update the content layout within the control, for example scroll bars. As always: do not paint here, but call Invalidate and paint using the OnPaint handler or an overridden Paint method.
