Class Ext.tree.TreeDropZone

Lets you specify a css class of elements that will not initiate a drag

Lets you to specify an element id for a child of a drag handle that should not initiate a drag

Allows you to specify a tag name that should not start a drag operation when clicked. This is designed to facilitate embedding links within a drag handle that do something other than start the drag.

Add this instance to a group of related drag/drop objects. All instances belong to at least one group, and can belong to as many groups as needed.

Applies the configuration parameters that were passed into the constructor. This is supposed to happen at each level through the inheritance chain. So a DDProxy implentation will execute apply config on DDProxy, DD, and DragDrop in order to get all of the parameters that are available in each object.

Clears any constraints applied to this instance. Also clears ticks since they can't exist independent of a constraint at this time.

Clears any tick interval defined for this instance

Initializes the drag drop object's constraints to restrict movement to a certain element. Usage:

var dd = new Ext.dd.DDProxy("dragDiv1", "proxytest",
                { dragElId: "existingProxyDiv" });
 dd.startDrag = function(){
     this.constrainTo("parent-id");
 };

Or you can initalize it using the Ext.Element object:

Ext.get("dragDiv1").initDDProxy("proxytest", {dragElId: "existingProxyDiv"}, {
     startDrag : function(){
         this.constrainTo("parent-id");
     }
 });

Fired when we are done dragging the object

Returns a reference to the actual element to drag. By default this is the same as the html element, but it can be assigned to another element. An example of this can be found in Ext.dd.DDProxy

Returns a reference to the linked element

Returns a custom data object associated with the DOM node that is the target of the event. By default this looks up the event target in the Ext.dd.Registry, although you can override this method to provide your own custom lookup.

Sets up the DragDrop object. Must be called in the constructor of any Ext.dd.DragDrop subclass

Initializes Targeting functionality only... the object does not get a mousedown handler.

Returns true if this instance is locked, or the drag drop mgr is locked (meaning that all drag/drop is disabled on the page.)

Checks the tag exclusion list to see if this click should be ignored

Lock this instance

The function a Ext.dd.DragSource calls once to notify this drop zone that the dragged item has been dropped on it. The drag zone will look up the target node based on the event passed in, and if there is a node registered for that event, it will delegate to onNodeDrop for node-specific handling, otherwise it will call onContainerDrop.

The function a Ext.dd.DragSource calls once to notify this drop zone that the source is now over the zone. The default implementation returns this.dropNotAllowed and expects that only registered drop nodes can process drag drop operations, so if you need the drop zone itself to be able to process drops you should override this method and provide a custom implementation.

The function a Ext.dd.DragSource calls once to notify this drop zone that the source has been dragged out of the zone without dropping. If the drag source is currently over a registered node, the notification will be delegated to onNodeOut for node-specific handling, otherwise it will be ignored.

The function a Ext.dd.DragSource calls continuously while it is being dragged over the drop zone. This method will be called on every mouse movement while the drag source is over the drop zone. It will call onNodeOver while the drag source is over a registered node, and will also automatically delegate to the appropriate node-specific methods as necessary when the drag source enters and exits registered nodes (onNodeEnter, onNodeOut). If the drag source is not currently over a registered node, it will call onContainerOver.

Override the onAvailable method to do what is needed after the initial position was determined.

Called when the DropZone determines that a Ext.dd.DragSource has been dropped on it, but not on any of its registered drop nodes. The default implementation returns false, so it should be overridden to provide the appropriate processing of the drop event if you need the drop zone itself to be able to accept drops. It should return true when valid so that the drag source's repair action does not run.

Called while the DropZone determines that a Ext.dd.DragSource is being dragged over it, but not over any of its registered drop nodes. The default implementation returns this.dropNotAllowed, so it should be overridden to provide the proper feedback if necessary.

Abstract method called during the onMouseMove event while dragging an object.

Abstract method called when this item is dropped on another DragDrop obj

Abstract method called when this element fist begins hovering over another DragDrop obj

Abstract method called when we are no longer hovering over an element

Abstract method called when this element is hovering over another DragDrop obj

Abstract method called when this item is dropped on an area with no drop target

Event handler that fires when a drag/drop obj gets a mousedown

Event handler that fires when a drag/drop obj gets a mouseup

Called when the DropZone determines that a Ext.dd.DragSource has been dropped onto the drop node. The default implementation returns false, so it should be overridden to provide the appropriate processing of the drop event and return true so that the drag source's repair action does not run.

Called when the DropZone determines that a Ext.dd.DragSource has entered a drop node that has either been registered or detected by a configured implementation of getTargetFromEvent. This method has no default implementation and should be overridden to provide node-specific processing if necessary.

Called when the DropZone determines that a Ext.dd.DragSource has been dragged out of the drop node without dropping. This method has no default implementation and should be overridden to provide node-specific processing if necessary.

Called while the DropZone determines that a Ext.dd.DragSource is over a drop node that has either been registered or detected by a configured implementation of getTargetFromEvent. The default implementation returns this.dropNotAllowed, so it should be overridden to provide the proper feedback.

Remove's this instance from the supplied interaction group

Unsets an invalid css class

Unsets an invalid handle id

Unsets an excluded tag name set by addInvalidHandleType

resetConstraints must be called if you manually reposition a dd element.

Allows you to specify that an element other than the linked element will be moved with the cursor during a drag

Allows you to specify a child of the linked element that should be used to initiate the drag operation. An example of this would be if you have a content div with text and links. Clicking anywhere in the content area would normally start the drag operation. Use this method to specify that an element inside of the content div is the element that starts the drag operation.

Stores the initial placement of the linked element.

Allows you to set an element outside of the linked element as a drag handle

Configures the padding for the target zone in px. Effectively expands (or reduces) the virtual object size for targeting calculations. Supports css-style shorthand; if only one parameter is passed, all sides will have that padding, and if only two are passed, the top and bottom will have the first param, the left and right the second.

By default, the element can be dragged any place on the screen. Use this method to limit the horizontal travel of the element. Pass in 0,0 for the parameters if you want to lock the drag to the y axis.

By default, the element can be dragged any place on the screen. Set this to limit the vertical travel of the element. Pass in 0,0 for the parameters if you want to lock the drag to the x axis.

Abstract method called after a drag/drop object is clicked and the drag or mousedown time thresholds have beeen met.
