|
| + * `IronResizableBehavior` is a behavior that can be used in Polymer elements to
|
| + * coordinate the flow of resize events between "resizers" (elements that control the
|
| + * size or hidden state of their children) and "resizables" (elements that need to be
|
| + * notified when they are resized or un-hidden by their parents in order to take
|
| + * action on their new measurements).
|
| + * Elements that perform measurement should add the `IronResizableBehavior` behavior to
|
| + * their element definition and listen for the `iron-resize` event on themselves.
|
| + * This event will be fired when they become showing after having been hidden,
|
| + * when they are resized explicitly by another resizable, or when the window has been
|
| + * resized.
|
| + * Note, the `iron-resize` event is non-bubbling.
