PrepRelatedObjectForChange

Description

Prepares some other related object for a change thats about to occur.

PROCEDURE PrepRelatedObjectForChange(objectAboutToBeChange : HANDLE);
def vs.PrepRelatedObjectForChange(objectAboutToBeChange):
    return None

Parameters

Name Type Description
objectAboutToBeChange HANDLE The object to be prepared for a change

Remarks

This call adds an eBeforeModify primitive to the specified object provided that the undo system is currently building an undo event.

Does this mean that the object is sent an event, and if so, what is the event code?

Examples

PrepRelatedObjectForChange(tempH1);
selHandles[TmpIndex] := ConvertToPolyline(selHandles[TmpIndex]);

	cen_pt.x := ObjLoc[TmpIndex].x+1";
	cen_pt.y := ObjLoc[TmpIndex].y+1";
	END;
tempH1 := selHandles[TmpIndex];
PrepRelatedObjectForChange(tempH1);
selHandles[TmpIndex] := ConvertToPolyline(selHandles[TmpIndex]);
tempH := CreateSeatLayoutObj(selHandles[TmpIndex], cen_pt, SelectedSymbolName, Auto);
END;
import vs

# Prepares some other related object for a change thats about to occur.
objectAboutToBeChange = vs.FSActLayer()  # handle to the first selected object on the active layer

vs.PrepRelatedObjectForChange(objectAboutToBeChange)
