Class Ext.dd.DragSource

Lets you specify a css class of elements that will 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.

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.

Event that fires prior to the onDrag event. Overrides Ext.dd.DragDrop.

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

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

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.

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

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

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

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

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

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

Remove's this instance from the supplied interaction group

Unsets an invalid handle id

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.

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

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.

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