Procedure Tiwform1.iwappformcreate (sender:tobject); begin  Iwrectangle1.visible: = False;             If IWRectangle1 is inside the IWRegion1 and has hidden the  iwregion1.renderinvisiblecontrols: = True;//If you do not specify Renderinvisiblecontrols : = True Then Set iwrectangle1.visible from the asynchronous event: = True will not be valid end; {onasyncclick}procedure Tiwform1.iwbutton1asyncclick (sender:tobject; eventparams:tstringlist); begin  Iwrectangle1.visible: = Not iwrectangle1.visible;end;

{Three tiwregion}procedure tiwform1.iwappformcreate (sender:tobject) with no nesting first; begin  Iwregion1.color: = $ff 0000;  Iwregion2.color: = $0000ff;  Iwregion3.color: = $00ff00;  Iwregion1.align: = altop;  Iwregion2.align: = Alleft;  Iwregion3.align: = alclient;  Iwregion1.splitter: = True;  Iwregion2.splitter: = True;end;
