Ext.dd.DragDropExt.dd.DDTargetExt.dd.DropTarget
A simple class that provides the basic implementation needed to make any element a drop target that can have +draggable items dropped onto it. The drop has no effect until an implementation of notifyDrop is provided.
+A named drag drop group to which this object belongs. If a group is specified, then this object will only +interact with other drag drop objects in the same group (defaults to undefined).
+The CSS class returned to the drag source when drop is allowed (defaults to "x-dd-drop-ok").
+The CSS class returned to the drag source when drop is allowed (defaults to "x-dd-drop-ok").
+The CSS class returned to the drag source when drop is not allowed (defaults to "x-dd-drop-nodrop").
+The CSS class returned to the drag source when drop is not allowed (defaults to "x-dd-drop-nodrop").
+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}).
+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.
+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.
+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)

+The function a Ext.dd.DragSource calls once to notify this drop target that the dragged item has +been dropped on it.
