DragDropManager is a singleton that tracks the element interaction for -all DragDrop items in the window. Generally, you will not call -this class directly, but it does have helper methods that could -be useful in your DragDrop implementations.
-In intersect mode, drag and drop interaction is defined by the -overlap of two or more drag and drop objects.
-In intersect mode, drag and drop interaction is defined by the -overlap of two or more drag and drop objects.
-In point mode, drag and drop interaction is defined by the -location of the cursor during the drag/drop
-In point mode, drag and drop interaction is defined by the -location of the cursor during the drag/drop
-The number of pixels that the mouse needs to move after the -mousedown before the drag is initiated. Default=3;
-The number of pixels that the mouse needs to move after the -mousedown before the drag is initiated. Default=3;
-The number of milliseconds after the mousedown event to initiate the -drag if we don't get a mouseup event. Default=350
-The number of milliseconds after the mousedown event to initiate the -drag if we don't get a mouseup event. Default=350
-Flag to determine if we should prevent the default behavior of the -events we define. By default this is true, but this can be set to -false if you need the default behavior (not recommended)
-Flag to determine if we should stop the propagation of the events -we generate. This is true by default but you may want to set it to -false if the html element contains other features that require the -mouse click.
-Helper function for getting the best match from the list of drag -and drop objects returned by the drag and drop events when we are -in INTERSECT mode. It returns either the first object that the -cursor is over, or the object that has the greatest overlap with -the dragged element.
-The array of drag and drop objects -targeted
-The best single match
-Returns the style property for the DOM element (i.e., -document.getElById(id).style)
-Returns the style property for the DOM element (i.e., -document.getElById(id).style)
-the id of the elment to get
-The style property of the element
-Returns the DragDrop instance for a given id
-Returns the DragDrop instance for a given id
-the id of the DragDrop object
-the drag drop object, null if it is not found
-Returns the actual DOM element
-Returns the actual DOM element
-the id of the elment to get
-The element -@deprecated use Ext.lib.Ext.getDom instead
-Returns a Region object containing the drag and drop element's position -and size, including the padding configured for it
-the drag and drop object to get the
- - location for
-a Region object representing the total area
- - the element occupies, including any padding
- the instance is configured for.
-Returns the drag and drop instances that are in all groups the -passed in instance belongs to.
-Returns the drag and drop instances that are in all groups the -passed in instance belongs to.
-the obj to get related data for
-if true, only return targetable objs
-the related instances
-Utility function to determine if a given element has been -registered as a drag drop item.
-Utility function to determine if a given element has been -registered as a drag drop item.
-the element id to check
-true if this element is a DragDrop item, -false otherwise
-Utility function to determine if a given element has been -registered as a drag drop handle for the given Drag Drop object.
-the element id to check
-true if this element is a DragDrop handle, false -otherwise
-Returns true if the specified dd target is a legal target for -the specifice drag obj
-Returns true if the specified dd target is a legal target for -the specifice drag obj
-the drag obj
-the target
-true if the target is a legal target for the -dd obj
-Is drag and drop locked?
-Is drag and drop locked?
-True if drag and drop is locked, false otherwise.
-My goal is to be able to transparently determine if an object is -typeof DragDrop, and the exact subclass of DragDrop. typeof -returns "object", oDD.constructor.toString() always returns -"DragDrop" and not the name of the subclass. So for now it just -evaluates a well-known variable in DragDrop.
-object to evaluate
-true if typeof oDD = DragDrop
-Refreshes the cache of the top-left and bottom-right points of the
-drag and drop objects in the specified group(s). This is in the
-format that is stored in the drag and drop instance, so typical
-usage is:
-
-Ext.dd.DragDropManager.refreshCache(ddinstance.groups);
-
-Alternatively:
-
-Ext.dd.DragDropManager.refreshCache({group1:true, group2:true});
-
-@TODO this really should be an indexed array. Alternatively this
-method could accept both.
an associative array of groups to refresh
-Each DragDrop instance must be registered with the DragDropManager. -This is executed in DragDrop.init()

-the DragDrop object to register
-the name of the group this element belongs to
-Each DragDrop handle element must be registered. This is done -automatically when executing DragDrop.setHandleElId()

-the DragDrop id this element is a handle for
-the id of the element that is the drag -handle
-Fired when either the drag pixel threshol or the mousedown hold -time threshold has been met.

-{int} the X position of the original mousedown

-Utility to stop event propagation and event default, if these -features are turned on.

-the event as returned by this.getEvent()
-This checks to make sure an element exists and is in the DOM. The -main purpose is to handle cases where innerHTML is used to remove -drag and drop objects from the DOM. IE provides an 'unspecified -error' when trying to access the offsetParent of such an element
-the element to check
-true if the element looks usable
