vsoStateGetLayrChng

Description

Used to determine if the layer scale have changed. See [[VS:Parametric State Notifications#vsoStateGetLayrChng]]

This function should be called during the parametric reset event: 3: {kParametricRecalculate}

FUNCTION vsoStateGetLayrChng(
				hObj             : HANDLE;
				VAR outOldScale  : REAL;
				VAR outNewScale  : REAL;
				VAR outScaleText : BOOLEAN): BOOLEAN;
def vs.vsoStateGetLayrChng(hObj):
    return (BOOLEAN, outOldScale, outNewScale, outScaleText)

Parameters

Name Type Description
hObj HANDLE Handle to the parametric object. Obtained by call to GetCustomObjectInfo
outOldScale REAL Output parameter. Old layer scale.
outNewScale REAL Output parameter. New layer scale.
outScaleText BOOLEAN Output parameter. Does the new scale affect texts.

Examples

VectorScript

BEGIN
  result := GetCustomObjectInfo(objectName, objectHand, recordHand, wallHand);
  vsoGetEventInfo(theEvent, message );

  CASE theEvent OF
    5: {kObjOnInitXProperties}
    BEGIN
      {enable eventing for this plug-in}
      SetPrefInt( 590, 1 ); {varParametricEnableStateEventing, kParametricStateEvent_ResetStatesEvent}
      result := SetObjPropVS(18, TRUE); {kObjXPropAcceptStates}
      result := SetObjPropVS( 2, TRUE ); {kObjXPropHasLayerScaleDeps}
    END;	

    44: {kObjOnAddState}
    BEGIN
      message := vsoStateAddCurrent( objectHand, message );
    END;

    3: {kParametricRecalculate}
    BEGIN
      MoveTo( 5mm, 8mm );
      CreateText( 'State events received after the last kParametricRecalculate:' );

      IF vsoStateGetLayrChng( objectHand, oldScale, newScale, scaleText ) THEN BEGIN
        MoveTo( 0,-60mm );
        CreateText( Concat( 'Layer changed! oldScale=', oldScale, ' newScale=', newScale, ' scaleText=', scaleText ) );
      END;
    END;
