nsIDragDropHandler is an interface for communicating with the built-in drag and drop implementation in the content area. Use this to register where the listeners should attach (something that implements
nsPIDOMEventTarget which is what we end up using under the hood).
Unregisters all handlers related to drag and drop.
Attaches drag handlers to a specified receiver, setting up callbacks to let built-in behaviors be overridden.
void hookupTo( in nsIDOMEventTarget attachPoint, in nsIWebNavigation navigator );
- The receiver to which to attach drag handlers.
nsIWebNavigationobject to handle the dropped URLs. If this is
NULL, the client must handle the drop itself, either through the method provided via
overrideDrop()or by letting the event bubble up through the DOM.
