Class Resizable

java.lang.Object
  com.extjs.gxt.ui.client.event.BaseObservable
      com.extjs.gxt.ui.client.fx.Resizable

All Implemented Interfaces:

Observable

public class Resizable
extends BaseObservable

Applies drag handles to a widget to make it resizable. The drag handles are inserted into the widget and positioned absolute.

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
 

Events:

ResizeStart : (source, widget, event)

Fires before a resize operation start. Listeners can cancel the action by calling BaseEvent.setCancelled(boolean).

• source : this
• component : resize widget
• event : the dom event

ResizeEnd : (source, widget, event)

Fires after a resize.

• source : this
• widget : resize widget
• event : the dom event
