Unfortunately this only worked for locking to the X-Axis.
Meaning you can only drag something left and right but not up and down.
The problem now is I cannot restrict dragging left/right.
This is because the DragProxy and it's children don't seem to report valid
widths.
Whenever I trace it out the width's are 0.
Also the coordinate space of the dragProxy doesn't seem to sync with anything
else in the app.
Even when I use dragProxy.systemManager.topLevelSystemManager.localToGlobal().
The DragProxy seems to set it's own position internally using
DisplayObject(sandboxRoot).globalToLocal(stagePoint);
But sandboxRoot is not accessible outside of DragProxy and I have no idea what
it actually references.
Any ideas?
All I am trying to do is limit how far you can drag the dragProxy left and
right so that it cannot be dragged outside the bounds of the list it is being
dragged from.
Thanks
