MXML Graphics: Verbose syntax for Path is gone

As of last week, the Flex SDK removed support for the ‘verbose’ syntax for creating Path data. In the past, you could create a Path using two methods:

short syntax, just using the ‘data’ property:

<s:Path data=”M  9 0 L 9 55 L 70 55 z” />

and the long “verbose” syntax which was more readable:

<Path>
<segments>
<MoveSegment x=”9″ y=”0″ />
<LineSegment x=”9″ y=”55″ />
<LineSegment x=”70″ y=”55″ />
<CloseSegment />
</segments>
</Path>

The long syntax is no longer supported. Here is more information, if you want to know the reasoning behind this change:

Also, here are additional changes that Deepa mentioned in her check-in notes for svn 8589.

1. Path.segments property removed. In its place, there is private variable (segments) which holds the path data parsed into the correct segment objects.

2. Path.segmentChanged() removed ?\226?\128?\147 Segments do not need to notify the parent path when their properties have changed since they are now not individually accessible.

3. PathSegment.segmentHost property removed ?\226?\128?\147 Segments do not need a pointer back to the parent Path since now they are now not individually accessible.

4. PathSegment.notifySegmentChanged() removed ?\226?\128?\147 Segments do not need to notify the parent Path they have changed since they are now not individually accessible.

5. PathSegment.dispatchSegmentChanged() removed ?\226?\128?\147 Path segments do not need to dispatch propertyChange events since they are now not individually accessible. As part of this, I have removed the [Bindable] and   [Inspectable] metadata from all PathSegment properties.

6. PathSegment no longer extends EventDispatcher, instead it extends Object.

7. All of the PathSegment and derivative classes no longer have getters/setters for their properties (like x, y, etc) since these properties are now not dispatching property change events.

8. A variety of checkintests/sparkTest project files have been updated to use the compact syntax as they are drawn/transitioned between state changes. Refer to sparkTest/AddItemsTest.mxml and RemoveItemsTest.mxml for examples on how to use states and transitions to transform Paths through the data they are bound to (as opposed to modifying individual segments).
