Examples of DragSource

com.extjs.gxt.ui.client.dnd.DragSource
Identifies a component that drag and drops can be initiated from.
Drag sources must set the data that will be dragged during a drag operation. The data can be specified either by using {@link #setData(Object)} or,setting the data via the DND event when a drag begins.
Drag sources are responsible for removing the dragged data from the source component after a valid drop. Use {@link DropTarget#getOperation()} todetermine if the data was copied or moved. The target is accessible via the DNDEvent passed to {@link #onDragDrop(DNDEvent)} and listeners.
Events:
DragStart : DNDEvent(source, component, event, dragEvent, status)

Fires after the user begins a drag and drop operation.
- source : this
- component : the source component
- event : the dom event
- dragEvent : the drag event (draggable)
- status : the status object
DragCancel : DNDEvent(source, component, event, dragEvent)

Fires after a drag is cancelled.
- source : this
- component : the source component
- event : the dom event
- dragEvent : the drag event (draggable)
Drop : DNDEvent(source, component, data, event, dragEvent, status)

Fires after a drop occurs.
- source : this
- component : the source component
- data : the transferred data
- event : the dom event
- dragEvent : the drag event (draggable)
- status : the status object
