aps/Container¶

This is used to create containers with an HTML code and/or a set of child widgets.

Every child widget (except for ``aps/Button``, ``aps/Output``, and ``aps/Status``) inside an ``aps/Container`` gets the ``gridSize`` attribute as explained in the CSS Grid Size section.

Overview ¶

It is possible to use one or more aps/Container widgets on the same page to group widgets. Each container is used as a parent with a group of widgets sharing a single title.

Depending on the way your widgets are declared, child elements are defined as follows:

Nested arrays in case of declaration through the widget loader
Using the addChild method in case of declaration through widget constructors
Hierarchy of widgets corresponding to the hierarchy of HTML DOM nodes when using the declarative syntax

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

Examples ¶

Basic Container¶

In the simplest case, a container is just a flat group of widgets:

RUN DEMO

require(["aps/load", "aps/ready!"],
  function(load){
    "use strict";
    load(["aps/PageContainer", [
        [ "aps/Container",
            [[ "aps/ProgressBar", { value: "35%" } ],
             [ "aps/ProgressBar", { value: "55%" } ],
             [ "aps/ProgressBar", { value: "75%" } ]]
      ]
    ]]);
});

Multi-Column Placement¶

Inside a container, you may group widgets in more than one column. Depending on control panel version, one of the following methods is possible:

The CP mode supports the cols property. It allows using one or two columns in a container. By default, cols equals 0. This makes the container place all child widgets in one column. To advance a container to 2 columns, you need to specify 2 as a value for the cols property.

RUN DEMO

require(["aps/load", "aps/ready!"],
 function(load) {
     load(["aps/PageContainer", [
         ["aps/Panel", [
                ["aps/Container", {cols: 2}, [
                    ["aps/TextBox", {
                        placeHolder: "Type email addresses here"
                    }],
                    ["aps/TextBox", {
                        placeHolder: "Type full name here"
                    }]
                ]]
            ]]
     ]]);
 });

UX1 supports the gridSize property that specifies the width for each child separately. This method is much more flexible than using cols. It allows to use up to 12 widgets with various width in a row.

RUN DEMO

require(["aps/load", "aps/ready!"],
function(load) {
    load(["aps/Panel", [
        ["aps/FieldSet", [
            ["aps/TextBox", {
                placeHolder: "Type email addresses here",
                gridSize: "md-8"
            }],
            ["aps/TextBox", {
                placeHolder: "Type full name here",
                gridSize: "md-6"
            }]
        ]]
    ]]);
});

../../../../../_images/container-gridsize.png

Descriptive Information¶

A container may display a title (the title property). A description (description) and supplemental information (hint) are environment sensitive.

RUN DEMO

require(["aps/load", "aps/ready!"],
function(load){
    "use strict";
    load(["aps/PageContainer", [
        ["aps/Panel", [
            ["aps/Container", {
                title:         "Resource Usage",
                description:   "Active downloads"
            }, [
                [ "aps/Gauge", {
                    legend: "Storage-1 usage: ${value} %",
                    value: 35,
                    gridSize: "md-8"
                }],
                [ "aps/Gauge", {
                    legend: "CPU usage: ${value} %",
                    value: 55,
                    gridSize: "md-8"
                }],
                [ "aps/Gauge", {
                    legend: "RAM usage: ${value} %",
                    value: 75,
                    gridSize: "md-8"
                }]
    ]]]]]]);
});

To display a horizontal line above a container that does not have a title text, you need to set the title property to true.

RUN DEMO

require(["aps/load", "aps/ready!"],
  function(load){
    "use strict";
    load(["aps/PageContainer", [
        ["aps/Panel", [
            [ "aps/Container", { title: true }, [
                [ "aps/Gauge", { value: 35 } ],
                [ "aps/Gauge", { value: 55 } ],
                [ "aps/Gauge", { value: 75 } ]]
            ]
        ]]
    ]]);
});

Ability to collapse¶

A container may provide a user an ability to collapse its content and leave only the title visible. To do this, you need to set the collapsible property to true.

RUN DEMO

require(["aps/load", "aps/ready!"],
  function(load){
    "use strict";
    load(["aps/PageContainer", [
        ["aps/Panel", [
            [ "aps/Container", { collapsible: true , title: "Collapsible" }, [
                [ "aps/Gauge", { value: 35 } ],
                [ "aps/Gauge", { value: 55 } ],
                [ "aps/Gauge", { value: 75 } ]]
            ]
        ]]
    ]]);
});

Inside FieldSet¶

A container may be a child element of an aps/FieldSet container. In this case, you should specify the label property of the container for correct operation of the FieldSet widget.

RUN DEMO

require(["aps/load", "aps/ready!"],
  function(load){
    "use strict";
    load(["aps/PageContainer", [
        ["aps/Panel", [
            [ "aps/FieldSet", {
                title:         "Form Elements -> Text Input -> Single Line",
                description:   "A single line text input is used to enter short strings."
            }, [
                [ "aps/Container", { label: "DNS zones for DNSBL service" }, [
                    [ "aps/TextBox"],
                    [ "aps/Output", {
                        "class":    "hint",
                        content:  "Separate entries with a semicolon"
                    }]
                ]],
                [ "aps/TextBox", {
                    label: "f-small-size", "class": "f-small-size",
                    autoSize: false
                }],
                [ "aps/TextBox", {
                    label: "f-limits", "class": "f-limits",
                    autoSize: false
                }],
                [ "aps/Container", { label: "f-date + f-date-year" }, [
                    [ "aps/TextBox", { "class": "f-date", autoSize: false }],
                    [ "aps/TextBox", { "class": "f-date-year", autoSize:   false }]
                ]
            ]]
    ]]]]]);
});

set ()	object function	Set a property of the Stateful instance
startup ()	undefined	Gets started after the DOM fragment is added to the document
validate ()	boolean	Called by oninit, onblur, and onkeypress

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

cancel¶

Sets the isBusy property to false.

Return: object

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 on the focusNode of the first suitable child

Return: aps/_container 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 ¶

EVENT	RETURN	DESCRIPTION
onClick ()	undefined	The method is called when a user clicks on the widget

onClick¶

The method is called when a user clicks on the widget.
