DomHelper to be used to create the
dialog's dom structure.
|
Creates the DOM structure that makes up the dialog's content area.
Returns: Element
The DOM structure that makes up the dialog's content area.

Creates and returns the event object to be used when dispatching the OK
event to listeners, or returns null to prevent the dialog from closing.
Arguments:
Returns: goog.demos.editor.HelloWorldDialog.OkEvent
The event object to be
used when dispatching the OK event to listeners.
|
code » | ||
Returns the hello world message currently typed into the dialog's input.
Returns: ?string
The hello world message currently typed into the dialog's
input, or null if called before the input is created.
|
code » |
Creates and returns the goog.ui.Dialog control that is being wrapped
by this object.
Returns: !goog.ui.Dialog
Created Dialog control.
|
code » | ||
Creates and returns the event object to be used when dispatching the OK
event to listeners, or returns null to prevent the dialog from closing.
Subclasses should override this to return their own subclass of
goog.events.Event that includes all data a plugin would need from the dialog.
Arguments:
Returns: goog.events.Event
The event object to be used when dispatching the
OK event to listeners.
|
code » | ||
![]()
Disposes of the dialog. If the dialog is open, it will be hidden and
AFTER_HIDE will be dispatched.
|
code » | ||
Returns the HTML Button element for the button added to this dialog with
the given button id.
|
code » | ||
Returns the HTML Button element for the Cancel button in this dialog.
Returns: Element
The button element if found, else null.
|
code » | ||
Returns the HTML Button element for the OK button in this dialog.
Returns: Element
The button element if found, else null.
|
code » | ||
![]()
Cleans up after the dialog is hidden and fires the AFTER_HIDE event. Should
be a listener for the wrapped dialog's AFTER_HIDE event.
|
code » | ||
Handles the event dispatched by the wrapped dialog control when the user
clicks the Cancel button. Simply dispatches a CANCEL event.
Returns: boolean
Returns false if any of the handlers called prefentDefault
on the event or returned false themselves.
|
code » | ||
Handles the event dispatched by the wrapped dialog control when the user
clicks the OK button. Attempts to create the OK event object and dispatches
it if successful.
Arguments:
Returns: boolean
Whether the default action (closing the dialog) should
still be executed. This will be false if the OK event could not be
created to be dispatched, or if any listener to that event returs false
or calls preventDefault.
|
code » | ||
![]()
Hides the dialog, causing AFTER_HIDE to fire.
|
code » | ||
No description.
Returns: boolean
Whether the dialog is open.
|
code » | ||
![]()
Runs the handler registered on the OK button event and closes the dialog if
that handler succeeds.
This is useful in cases such as double-clicking an item in the dialog is
equivalent to selecting it and clicking the default button.
|
code » | ||
![]()
Causes the dialog box to appear, centered on the screen. Lazily creates the
dialog if needed.
|
code » |
![]()
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:
|
code » | |||||
![]()
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.

there is no parent.

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:
|
code » | |||||
![]()
Sets the parent of this event target to use for capture/bubble
mechanism.
Arguments:
|
code » | |||||
![]()
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'); }; |

![]()
Associates a disposable object with this object so that they will be disposed
together.
Arguments:

The object to use for event.target. Useful when mixing in an
EventTarget to another object.

Maps of event type to an array of listeners.
|
Code » | |
Parent event target, used during event bubbling.
TODO(user): Change this to goog.events.Listenable. This
currently breaks people who expect getParentEventTarget to return
goog.events.EventTarget.

Returns whether or not the given message contains the strings "hello" and
"world". Case-insensitive and order doesn't matter.
