               goog.ui.Zippy

Constructor

goog.ui.Zippy(headeropt_contentopt_expanded)

Parameters

header :
Header element, either element reference or string id.
opt_content :
Content element (if any), either element reference or string id. If skipped, the caller should handle the TOGGLE event in its own way.
opt_expanded :
Initial expanded/visibility state. Defaults to false.

onHeaderClick_(event)
Click event handler for header element.
Arguments:
event :
Click event.
code »
onHeaderKeyDown_(event)
KeyDown event handler for header element. Enter and space toggles expanded state.
Arguments:
event :
KeyDown event.

Arguments:
expanded :
Expanded/visibility state.

updateHeaderClassName_(expanded)
Updates the header element's className
Arguments:
expanded :
Expanded/visibility state.
code »
addEventListener(typehandleropt_captureopt_handlerScope)
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.
Arguments:
type :
The type of the event to listen for.
handler :
The function to handle the event. The handler can also be an object that implements the handleEvent method which takes the event object as argument.
opt_capture :
In DOM-compliant browsers, this determines whether the listener is fired during the capture or bubble phase of the event.
opt_handlerScope :
Object in whose scope to call the listener.
code »
dispatchEvent(e)
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.
Arguments:
e :
Event object.
Returns:   If anyone called preventDefault on the event object (or if any of the handlers returns false this will also return false.
code »
disposeInternal()
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
};
code »
getParentEventTarget()
Returns the parent of this event target to use for bubbling.
Returns:   The parent EventTarget or null if there is no parent.
code »
removeEventListener(typehandleropt_captureopt_handlerScope)
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:
type :
The type of the event to listen for.
handler :
The function to handle the event. The handler can also be an object that implements the handleEvent method which takes the event object as argument.
opt_capture :
In DOM-compliant browsers, this determines whether the listener is fired during the capture or bubble phase of the event.
opt_handlerScope :
Object in whose scope to call the listener.
code »
setParentEventTarget(parent)
Sets the parent of this event target to use for bubbling.
Arguments:
parent :
Parent EventTarget (null if none).
code »
dispose()
No description.
code »
disposeInternal()
Deletes or nulls out any references to COM objects, DOM nodes, or other disposable objects. Classes that extend {@code goog.Disposable} should override this method. For example:
mypackage.MyClass = function() {
goog.Disposable.call(this);
// Constructor logic specific to MyClass.
...
};
goog.inherits(mypackage.MyClass, goog.Disposable);

mypackage.MyClass.prototype.disposeInternal = function() {
mypackage.MyClass.superClass_.disposeInternal.call(this);
// Dispose logic specific to MyClass.
...
};
code »
getDisposed()
No description.
Returns:   Whether the object has been disposed of.
code »
isDisposed()
No description.
Returns:   Whether the object has been disposed of.

Parent event target, used during event bubbling.

Whether the object has been disposed of.
