Class Ext.grid.GridDragZone

Package:	Ext.grid
Defined In:	GridDD.js
Class:	GridDragZone
Extends:	DragZone

A customized implementation of a DragZone which provides default implementations of two of the template methods of DragZone to enable dragging of the selected rows of a GridPanel.

A cooperating DropZone must be created who's template method implementations of onNodeEnter, onNodeOver, onNodeOut and onNodeDrop

are able to process the data which is provided.

If a group is specified, then this object will only interact with other drag drop objects in the same group (defaults to undefined).	DragSource
	dropAllowed : String The CSS class returned to the drag source when drop is allowed (defaults to "x-dd-drop-ok").	DragSource
	dropNotAllowed : String The CSS class returned to the drag source when drop is not allowed (defaults to "x-dd-drop-nodrop").	DragSource

Public Properties

Property		Defined By
	Ext.dd.DDProxy.dragElId : String The default drag frame div id	DDProxy

By default the frame is positioned exactly where the drag element is, so we use the cursor offset provided by Ext.dd.DD. Another option that works only if you do not have constraints on the obj is to have the drag frame centered around the cursor. Set centerFrame to true for this effect.	DDProxy
	config : object Configuration attributes passed into the constructor	DragDrop
	defaultPadding : Object Provides default constraint padding to "constrainTo" elements (defaults to {left: 0, right:0, top:0, bottom:0}).	DragDrop

This property contains the data representing the dragged object. This data is set up by the implementation of the getDragData method. It must contain a `ddel` property, but can contain any other data according to the application's needs.	DragZone

The group defines a logical collection of DragDrop objects that are related. Instances only get events when interacting with other DragDrop object in the same group. This lets us define multiple groups using a single DragDrop subclass if we want.	DragDrop

By default, drags can only be initiated if the mousedown occurs in the region the linked element is. This is done in part to work around a bug in some browsers that mis-report the mousedown if the previous mouseup happened outside of the window. This property is set to true if outer handles are defined.	DragDrop

This is what we refer to as the "linked element" because the size and position of this element is used to determine when the drag and drop objects have interacted.	DragDrop

Set to false to enable a DragDrop object to fire drag events while dragging over its own Element. Defaults to true - DragDrop objects do not by default fire drag events to themselves.	DragDrop

An object who's property names identify the IDs of elements to be considered invalid as drag handles. A non-null property value identifies the ID as invalid. For example, to prevent dragging from being initiated on element ID "foo", use: `{ foo: true }`	DragDrop
	invalidHandleTypes : Object An object who's property names identify HTML tags to be considered invalid as drag handles. A non-null property value... An object who's property names identify HTML tags to be considered invalid as drag handles. A non-null property value identifies the tag as invalid. Defaults to the following value which prevents drag operations from being initiated by <a> elements: `{ A: "A" }`	DragDrop

When set to true, other DD objects in cooperating DDGroups do not receive notification events when this DD object is dragged over them. Defaults to false.	DragDrop
