goog.fx.DragDropItem(element, opt_data)
Class representing a source or target element for drag and drop operations.
element
{Element
|string
}
opt_data
{Object
=}
.addEventListener(type, handler, opt_capture, opt_handlerScope)
Inherited from goog.events.EventTarget
.
Adds an event listener to the event target. The same handler can only be added once per the type. Even if you add the same handler multiple times using the same type then it will only be called once when the event is dispatched. Supported for legacy but use goog.events.listen(src, type, handler) instead.
type
{string
}
handler
{Function
|Object
}
opt_capture
{boolean
=}
opt_handlerScope
{Object

.addOnDisposeCallback(callback, opt_scope)
Inherited from goog.Disposable
.
Invokes a callback function when this object is disposed. Callbacks are invoked in the order in which they were added.
callback
{!Function
}
opt_scope
{Object
=}
.creationStack
{string
}Inherited from goog.Disposable
.
If monitoring the goog.Disposable instances is enabled, stores the creation stack trace of the Disposable instance.
.data
{Object
|undefined
}Data associated with element.
.dispatchEvent(e)
Inherited from goog.events.EventTarget
.
Dispatches an event (or event like object) and calls all listeners listening for events of this type. The type of the event is decided by the type property on the event object. If any of the listeners returns false OR calls preventDefault then this function will return false. If one of the capture listeners calls stopPropagation, then the bubble listeners won't fire.
e
{string
|Object
|goog.events.Event
}
boolean
}
.dispose()
Inherited from goog.Disposable
.
Disposes of the object. If the object hasn't already been disposed of, calls {@link #disposeInternal}. Classes that extend {@code goog.Disposable} should override {@link #disposeInternal} in order to delete references to COM objects, DOM nodes, and other disposable objects. Reentrant.
void
}
.disposeInternal()
[protected]Inherited from goog.events.EventTarget
.
Unattach listeners from this object. Classes that extend EventTarget may need to override this method in order to remove references to DOM Elements and additional listeners, it should be something like this:
MyClass.prototype.disposeInternal = function() { MyClass.superClass_.disposeInternal.call(this); // Dispose logic for MyClass };
.element
{Element
}Reference to drag source/target element
.getCurrentDragElement()
Gets the element that is currently being dragged.
Element
}
.getData()
Get the data associated with the source/target.
Object
|null
|undefined
}
.getDisposed
[deprecated]Deprecated. Use {@link #isDisposed} instead.
Inherited from goog.Disposable
.
boolean
}
.getDraggableElement(target)
Gets the element that is actually draggable given that the given target was attempted to be dragged. This should be overriden when the element that was given actually contains many items that can be dragged. From the target, you can determine what element should actually be dragged.
target
{Element
}
Element
}
.getDraggableElements()
Gets all the elements of this item that are potentially draggable/
Array

.getParentEventTarget()
Inherited from goog.events.EventTarget
.
Returns the parent of this event target to use for bubbling.

.isDisposed()
Inherited from goog.Disposable

boolean
}
.registerDisposable(disposable)
Inherited from goog.Disposable
.
Associates a disposable object with this object so that they will be disposed together.
disposable
{goog.disposable.IDisposable
}
.removeEventListener(type, handler, opt_capture, opt_handlerScope)
Inherited from goog.events.EventTarget
.
Removes an event listener from the event target. The handler must be the same object as the one added. If the handler has not been added then nothing is done.

.setParent(parent)
Sets the dragdrop to which this item belongs.
parent
{goog.fx.AbstractDragDrop
}
.setParentEventTarget(parent)
Inherited from goog.events.EventTarget
.
Sets the parent of this event target to use for bubbling.
