aps/Panel

Highlighted block that can contain widgets.

Overview

Structure

It is a separate visual block containing other widgets. The widget can show its status, for example, Loading.

Find the nested rules for this widget in the recommended Widget Hierarchy.

You can add widgets to aps/Panel in the same way as you would do it for aps/Container.

Status

The busy or loading status prevents users from submission of a method when the previous method is not completed yet. If you need to set a panel to the busy or loading status, set respectively the isBusy or isLoad property to true. When the panel is busy, it is visible but not available for operations. When the panel is loading, the loadLabel property is displayed. Method cancel turns off both of the statuses, busy and loading.

Example

In the following sample code, the Panel contains a TextArea widget with a text inside it.

RUN DEMO

require([
    "aps/load",
    "aps/ready!"
], function(load) {
    load(["aps/Panel", {
            title: "Specify User Email Addresses"
        },
        [
            ["aps/TextArea", {
                placeHolder: "Type email addresses here" +
                	"to send invitations to the new users." +
                  "Start the second and following address" +
                	"from the new line or use commas.",
                rows: 3
            }]
        ]
    ]);
});

Public Methods

METHOD

RETURN

undefined

Destroys this widget

focus ()
aps/_containerbase
function

Focusing the focusable child

any

Get a property of the Stateful instance

getChildren ()
array

Returns all direct children of this widget, i

array

Discover and return all parents of the widget

placeAt ()
dijit/_widgetbase
function

Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions

validate ()
boolean

addChild

Makes the given widget a child of this widget. Inserts specified child widget’s dom node as a child of this widget’s container node, and possibly does other processing (such as layout).

Return: undefined

ARGUMENT

TYPE

DESCRIPTION

child
Widget

Child widget

insertIndex
Number
String

Position child in the parent widget

cancel

To prevent double submission by a user, widget is switched to the busy or load state automatically each time after the user clicks. To switch the button back to the enabled state, call the cancel() method in your onClick handler.

Return: any

destroy

Destroys this widget. Will also destroy any resources (including widgets) registered via this.own(). This method will also destroy internal widgets such as those created from a template.

Return: undefined

focus

Focusing the focusable child

Return: aps/_containerbase function

get

Get a property of the Stateful instance. Get a named property of the Stateful object. The property may potentially be retrieved via a getter method in subclasses.

In the base class, this just retrieves the object’s property.

Return: any

getChildren

Returns all direct children of this widget, i.e. all widgets underneath this.containerNode whose parent is this widget. Note that it returns not all descendetns, but only the direct children. Analogous to Node.childNodes, except containing widgets rather than DOMNodes.

The result intentionally excludes internally created widgets (a.k.a. supporting widgets) outside of this.containerNode.

Note the returned array is a simple array. The application code should not assume existence of methods like forEach().

Return: array

getParents

Discover and return all parents of the widget.

Return: array

placeAt

Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions. A convenience function providing a simple shorthand mechanism to put an existing (or newly created) widget somewhere in the DOM, and allow chaining.

Return: dijit/_widgetbase function

removeAll

Remove all children in the widget.

Return: undefined

removeChild

Removes the passed widget instance from this widget and destroys it. You can also pass in an integer indicating the index within the container to remove (ie, removeChild(5) removes the sixth widget).

Return: undefined

ARGUMENT

TYPE

DESCRIPTION

widget
Widget
Int

Child widget or index

reset

Resets the widget.

Return: undefined

set

Set a property of the Stateful instance. Sets named properties of the stateful object and notifies the watchers of the property. A programmatic setter may be defined in subclasses.

Return: object function

startup

Gets started after the DOM fragment is added to the document Called after the widget and its children have been created and added to the page, and all related widgets have finished their create() cycle, up through postCreate().

Note that startup() may be called while the widget is still hidden, for example if the widget is inside a hidden dijit/Dialog or an unselected tab of a dijit/layout/TabContainer. For widgets that need to do layout, it’s best to put that layout code inside resize(), and then extend dijit/layout/_LayoutWidget so that resize() is called when the widget is visible.

Return: undefined

validate

Called by oninit, onblur, and onkeypress. Show missing or invalid messages if appropriate, and highlight textbox field.

Return: boolean

Public Events
