Méthodes publiques

Méthode	Description
AddInvalidHandleClass ( string cssClass ) : void	Lets you specify a css class of elements that will not initiate a drag
AddInvalidHandleId ( string id ) : void	Lets you to specify an element id for a child of a drag handle that should not initiate a drag
AddInvalidHandleType ( string tagName ) : void	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.
AddToGroup ( string sGroup ) : void	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.
ApplyConfig ( ) : void	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.
ClearConstraints ( ) : void	Clears any constraints applied to this instance. Also clears ticks since they can't exist independent of a constraint at this time.
ClearTicks ( ) : void	Clears any tick interval defined for this instance
ConstrainTo ( string constrainTo ) : void	Initializes the drag drop object's constraints to restrict movement to a certain element.
ConstrainTo ( string constrainTo, Paddings pad, bool inContent ) : void	Initializes the drag drop object's constraints to restrict movement to a certain element.
Destroy ( ) : void
Lock ( ) : void	Lock this instance
RemoveFromGroup ( string sGroup ) : void	Remove's this instance from the supplied interaction group
RemoveInvalidHandleClass ( string cssClass ) : void	Unsets an invalid css class
RemoveInvalidHandleId ( string id ) : void	Unsets an invalid handle id
RemoveInvalidHandleType ( string tagName ) : void	Unsets an excluded tag name set by addInvalidHandleType
ResetConstraints ( bool maintainOffset ) : void	resetConstraints must be called if you manually reposition a dd element.
SetDragElId ( string id ) : void	Allows you to specify that an element other than the linked element will be moved with the cursor during a drag
SetHandleElId ( string id ) : void	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.
SetInitPosition ( int diffX, int diffY ) : void	Stores the initial placement of the linked element.
SetOuterHandleElId ( string id ) : void	Allows you to set an element outside of the linked element as a drag handle
SetPadding ( int iTop, int iRight, int iBot, int iLeft ) : void	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.
SetXConstraint ( int iLeft, int iRight, int iTickSize ) : void	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.
SetYConstraint ( int iUp, int iDown, int iTickSize ) : void	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.
Unlock ( ) : void	Unlock this instace
Unreg ( ) : void	Remove all drag and drop hooks for this element
