monitors.

![]()
Handles an event indicating that the loading status of the iframe has
changed. In Firefox this is a goog.events.EventType.LOAD event, in IE
this is a goog.events.EventType.READYSTATECHANGED
|

![]()
Use
#listen instead, when possible. Otherwise, use
goog.events.listen if you are passing Object
(instead of Function) as handler.
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.
Arguments:

![]()
Asserts that the event target instance is initialized properly.

![]()
Removes 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.

Use
#unlisten instead, when possible. Otherwise, use
goog.events.unlisten if you are passing Object
(instead of Function) as handler.
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.
Arguments:

![]()
Sets the parent of this event target to use for capture/bubble
mechanism.
Arguments:

![]()
Sets the target to be used for
event.target when firing
event. Mainly used for testing. For example, see
goog.testing.events.mixinListenable .

![]()
Invokes a callback function when this object is disposed. Callbacks are
invoked in the order in which they were added.
Arguments:
|
code » | |||
![]()
Disposes of the object. If the object hasn't already been disposed of, calls
#disposeInternal . Classes that extend goog.Disposable should
override #disposeInternal in order to delete references to COM
objects, DOM nodes, and other disposable objects. Reentrant.
Returns: void
Nothing.
|
code » | |||
![]()
Deletes or nulls out any references to COM objects, DOM nodes, or other
disposable objects. Classes that extend
goog.Disposable should
override this method.
Not reentrant. To avoid calling it twice, it must only be called from the
subclass' disposeInternal method. Everywhere else the public
dispose method must be used.
For example:
mypackage.MyClass = function() { mypackage.MyClass.base(this, 'constructor'); // Constructor logic specific to MyClass. ... }; goog.inherits(mypackage.MyClass, goog.Disposable); mypackage.MyClass.prototype.disposeInternal = function() { // Dispose logic specific to MyClass. ... // Call superclass's disposeInternal at the end of the subclass's, like // in C++, to avoid hard-to-catch issues. mypackage.MyClass.base(this, 'disposeInternal'); }; |

currently breaks people who expect getParentEventTarget to return
goog.events.EventTarget.
