If you take a look at some existing Auto Shapes (in the Configuration/Auto Shapes folder and in
the Configuration/Auto Shape Tools folders), you'll notice a
beginning of the file. The Auto Shape JavaScript code in these files uses a
the initial message handler in the file. The
Fireworks so each message (that is useful to the particular Auto Shape) invokes a corresponding
function.
You can see this
Shape object may not need to process every message Fireworks sends, so only the useful messages
are written into the JavaScript file using the
case of a certain message, or messages, perform the following function.
In the Frame Auto Shape, this code is used to call
a
"SmartShapeEdited"
switch(smartShape.operation) {
case "BeginDragInsert":
case "InsertSmartShapeAt":
InsertSmartShapeAt(true);
break;
case "BeginDragControlPoint":
BeginDragControlPoint();
break;
case "DragControlPoint":
DragControlPoint();
break;
case "EndDragControlPoint":
EndDragControlPoint();
break;
case "SmartShapeEdited":
PlaceControlPoints();
break;
}
You don't need a response for every message Fireworks sends; but you do need to make sure the
statement handles the responses required by your shape.

You can also invoke a single function for several messages:
case "BeginDragInsert":
case "InsertSmartShapeAt":
InsertSmartShapeAt(true);
break;
