ADOBE FIREWORKS CS3 281 Extending Guide You can see this switch statement in each of the Auto Shape JavaScript files. Again, a single Auto 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 qualifier. Effectively, the JavaScript file states in case of a certain message, or messages, perform the following function. In the Frame Auto Shape, this code is used to call PlaceControlPoints() when Fireworks sends a "SmartShapeEdited" message: 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 switch 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;
