Ext.dd.DragDropExt.dd.DDTarget
A DragDrop implementation that does not move, but can be a drop -target. You would get the same result by simply omitting implementation -for the event callbacks, but this way we reduce the processing cost of the -event listener and the callbacks.
-The available property is false until the linked dom element is accessible.

-Provides default constraint padding to "constrainTo" elements (defaults to {left: 0, right:0, top:0, bottom:0}).
-Provides default constraint padding to "constrainTo" elements (defaults to {left: 0, right:0, top:0, bottom:0}).
-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. An object in the format {'group1':true, 'group2':true}
-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. @default false
-The id of the element associated with this object. 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.
-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.
-An Array of CSS class names for elements to be considered in valid as drag handles.
-An Array of CSS class names for elements to be considered in valid as drag handles.
-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
-}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"
-}By default, all instances can be a drop target. This can be disabled by -setting isTarget to false.
-By default, all instances can be a drop target. This can be disabled by -setting isTarget to false.
-Maintain offsets when we resetconstraints. Set to true when you want -the position of the element relative to its parent to stay the same -when the page changes
-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.
-The padding configured for this drag and drop object for calculating -the drop zone intersection with this object. An array containing the 4 padding values: [top, right, bottom, left]
-By default the drag and drop instance will only respond to the primary -button click (left button for a right-handed mouse). Set to true to -allow drag and drop to start with any mouse click that is propogated -by the browser
-Array of pixel locations the element will snap to if we specified a -horizontal graduation/interval. This array is generated automatically -when you define a tick interval.
-
the id of the element that is a drop target
-the group of related DragDrop objects
-an object containing configurable attributes
- - Valid properties for DDTarget in addition to those in
- DragDrop:
- none
-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
-Lets you to specify an element id for a child of a drag handle -that should not initiate a drag
-the element id of the element you wish to ignore
-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.
-the type of element to exclude
-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.
-{string} the name of the group
-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
-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.core.Element object:
- - Ext.get("dragDiv1").initDDProxy("proxytest", {dragElId: "existingProxyDiv"}, {
- startDrag : function(){
- this.constrainTo("parent-id");
- }
- });
- The element to constrain to.
-(optional) Pad provides a way to specify "padding" of the constraints, -and can be either a number for symmetrical padding (4 would be equal to {left:4, right:4, top:4, bottom:4}) or -an object containing the sides to pad. For example: {right:10, bottom:10}
-(optional) Constrain the draggable in the content box of the element (inside padding and borders)
