Resizable (GXT 4.0.2)

java.lang.Object
- com.sencha.gxt.widget.core.client.Resizable

All Implemented Interfaces:

ResizeEndEvent.HasResizeEndHandlers, ResizeStartEvent.HasResizeStartHandlers
```
public class Resizable
extends Object
implements ResizeStartEvent.HasResizeStartHandlers, ResizeEndEvent.HasResizeEndHandlers
```
Applies drag handles to a widget to make it resizable. The drag handles are inserted into the widget and positioned absolute.

Only Component instances can be used with Resizable as Widget's do not fire resize events. Widgets can be wrapped in a WidgetComponent instance to use with Resizable.

Here is the list of valid resize handles:
```
 Value   Description
 ------  -------------------
 'n'     north
 's'     south
 'e'     east
 'w'     west
 'nw'    northwest
 'sw'    southwest
 'se'    southeast
 'ne'    northeast
 'all'   all
 
```
