Class Ext.dd.DragSource

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.

Sets the element to the location of the mousedown or click event, maintaining the cursor location relative to the location on the element that was clicked. Override this if you want to place the element in a location other than where the cursor is.

Sets up config options specific to this class. Overrides Ext.dd.DragDrop, but all versions of this method through the inheritance chain are called

Sets the pointer offset to the distance between the linked element's top left corner and the location the element was clicked

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

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

Saves the most recent position so that we can reset the constraints and tick marks on-demand. We need to know this so that we can calculate the number of pixels the element is offset from its original position.

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");
     }
 });

Creates the proxy element if it does not yet exist

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

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

Initialization for the drag frame element. Must be called in the constructor of all subclasses

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

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 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

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.

Sets the pointer offset. You can call this directly to force the offset to be in a particular location (e.g., pass in 0,0 to set it to the center of the object)

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

Sets the drag element to the location of the mousedown or click event, maintaining the cursor location relative to the location on the element that was clicked. Override this if you want to place the element in a location other than where the cursor is.

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.
