TControl.DoSetBounds

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

Declaration

Source position: controls.pp line 1395

protected procedure TControl.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.
