Properties

_aria_attr
_attachEvents
Defined by: dijit/_AttachMixin

List of connections associated with data-dojo-attach-event=... in the template

_attachPoints
Defined by: dijit/_AttachMixin

List of widget attribute names associated with data-dojo-attach-point=... in the template, ex: ["containerNode", "labelNode"]

_attrPairNames
Defined by: dijit/_WidgetBase
_blankGif
Defined by: dijit/_WidgetBase

Path to a blank 1x1 image. Used by <img> nodes in templates that really get their image via CSS background-image.

_focusManager
Defined by: dijit/_FocusMixin
_onChangeActive

Indicates that changes to the value should call onChange() callback. This is false during widget initialization, to avoid calling onChange() when the initial value is set.

_rendered
Defined by: dijit/_TemplatedMixin

Not normally use, but this flag can be set by the app if the server has already rendered the template, i.e. already inlining the template for the widget into the main page. Reduces _TemplatedMixin to just function like _AttachMixin.

_setClassAttr
Defined by: dijit/_WidgetBase
_setDirAttr
Defined by: dijit/_WidgetBase
_setIconClassAttr
Defined by: dijit/form/CheckBox
_setIdAttr
Defined by: dijit/_WidgetBase
_setLangAttr
Defined by: dijit/_WidgetBase
_setNameAttr
Defined by: dijit/form/CheckBox
_setTabIndexAttr
_setTypeAttr
Defined by: dijit/_WidgetBase
_skipNodeCache
Defined by: dijit/_TemplatedMixin
_started
Defined by: dijit/_WidgetBase

startup() has completed.

active
Defined by: dijit/_CssStateMixin

True if mouse was pressed while over this widget, and hasn't been released yet

alt

Corresponds to the native HTML <input> element's attribute.

aria-label
attachScope
Defined by: dijit/_AttachMixin

Object to which attach points and events will be scoped. Defaults to 'this'.

attributeMap
Defined by: dijit/_WidgetBase

Deprecated. Instead of attributeMap, widget should have a _setXXXAttr attribute for each XXX attribute to be mapped to the DOM.

attributeMap sets up a "binding" between attributes (aka properties) of the widget and the widget's DOM. Changes to widget attributes listed in attributeMap will be reflected into the DOM.

For example, calling set('title', 'hello') on a TitlePane will automatically cause the TitlePane's DOM to update with the new title.

attributeMap is a hash where the key is an attribute of the widget, and the value reflects a binding to a:

  • DOM node attribute

    focus: {node: "focusNode", type: "attribute"} Maps this.focus to this.focusNode.focus

  • DOM node innerHTML

    title: { node: "titleNode", type: "innerHTML" } Maps this.title to this.titleNode.innerHTML

  • DOM node innerText

    title: { node: "titleNode", type: "innerText" } Maps this.title to this.titleNode.innerText

  • DOM node CSS class

    myClass: { node: "domNode", type: "class" } Maps this.myClass to this.domNode.className

If the value is an array, then each element in the array matches one of the formats of the above list.

There are also some shorthands for backwards compatibility:

  • string --> { node: string, type: "attribute" }, for example:
"focusNode" ---> { node: "focusNode", type: "attribute" }
  • "" --> { node: "domNode", type: "attribute" }
baseClass
checked

Corresponds to the native HTML <input> element's attribute. In markup, specified as "checked='checked'" or just "checked". True if the button is depressed, or the checkbox is checked, or the radio button is selected, etc.

class
Defined by: dijit/_WidgetBase
containerNode
Defined by: dijit/_WidgetBase

Designates where children of the source DOM node will be placed. "Children" in this case refers to both DOM nodes and widgets. For example, for myWidget:

<div data-dojo-type=myWidget>
    <b> here's a plain DOM node
    <span data-dojo-type=subWidget>and a widget</span>
    <i> and another plain DOM node </i>
</div>

containerNode would point to:

<b> here's a plain DOM node
<span data-dojo-type=subWidget>and a widget</span>
<i> and another plain DOM node </i>

In templated widgets, "containerNode" is set via a data-dojo-attach-point assignment.

containerNode must be defined for any widget that accepts innerHTML (like ContentPane or BorderContainer or even Button), and conversely is null for widgets that don't, like TextBox.

cssStateNodes
Defined by: dijit/_CssStateMixin

Subclasses may define a cssStateNodes property that lists sub-nodes within the widget that need CSS classes applied on mouse hover/press and focus.

Each entry in this optional hash is a an attach-point name (like "upArrowButton") mapped to a CSS class name (like "dijitUpArrowButton"). Example:

{
    "upArrowButton": "dijitUpArrowButton",
    "downArrowButton": "dijitDownArrowButton"
}

The above will set the CSS class dijitUpArrowButton to the this.upArrowButton DOMNode when it

is hovered, etc.

dir
Defined by: dijit/_WidgetBase

Bi-directional support, as defined by the HTML DIR attribute. Either left-to-right "ltr" or right-to-left "rtl". If undefined, widgets renders in page's default direction.

disabled

Should this widget respond to user input? In markup, this is specified as "disabled='disabled'", or just "disabled".

domNode
Defined by: dijit/_WidgetBase

This is our visible representation of the widget! Other DOM Nodes may by assigned to other properties, usually through the template system's data-dojo-attach-point syntax, but the domNode property is the canonical "top level" node in widget UI.

focused
Defined by: dijit/_FocusMixin

This widget or a widget it contains has focus, or is "active" because it was recently clicked.

hovering
Defined by: dijit/_CssStateMixin

True if cursor is over this widget

iconClass
Defined by: dijit/form/Button

Class to apply to DOMNode in button to make it display an icon

id
Defined by: dijit/_WidgetBase

A unique, opaque ID string that can be assigned by users or by the system. If the developer passes an ID which is known not to be unique, the specified ID is ignored and the system-generated ID is used instead.

intermediateChanges

Fires onChange for each value change or only on demand

label

Content to display in button.

lang
Defined by: dijit/_WidgetBase

Rarely used. Overrides the default Dojo locale used to render this widget, as defined by the HTML LANG attribute. Value must be among the list of locales specified during by the Dojo bootstrap, formatted according to RFC 3066 (like en-us).

name

Name used when submitting form; same as "name" attribute or plain HTML elements

ownerDocument
Defined by: dijit/_WidgetBase

The document this widget belongs to. If not specified to constructor, will default to srcNodeRef.ownerDocument, or if no sourceRef specified, then to the document global

readOnly

Should this widget respond to user input? In markup, this is specified as "readOnly". Similar to disabled except readOnly form values are submitted.

scrollOnFocus

On focus, should this widget scroll into view?

searchContainerNode
Defined by: dijit/_TemplatedMixin
showLabel
Defined by: dijit/form/Button

Set this to true to hide the label text and display only the icon. (If showLabel=false then iconClass must be specified.) Especially useful for toolbars. If showLabel=true, the label will become the title (a.k.a. tooltip/hint) of the icon.

The exception case is for computers in high-contrast mode, where the label will still be displayed, since the icon doesn't appear.

srcNodeRef
Defined by: dijit/_WidgetBase

pointer to original DOM node

style
Defined by: dijit/_WidgetBase

HTML style attributes as cssText string or name/value hash

tabIndex

Order fields are traversed when user hits the tab key

templatePath
Defined by: dijit/_TemplatedMixin

Path to template (HTML file) for this widget relative to dojo.baseUrl. Deprecated: use templateString with require([... "dojo/text!..."], ...) instead

templateString
Defined by: dijit/form/CheckBox
title
Defined by: dijit/_WidgetBase

HTML title attribute.

For form widgets this specifies a tooltip to display when hovering over the widget (just like the native HTML title attribute).

For TitlePane or for when this widget is a child of a TabContainer, AccordionContainer, etc., it's used to specify the tab label, accordion pane title, etc. In this case it's interpreted as HTML.

tooltip
Defined by: dijit/_WidgetBase

When this widget's title attribute is used to for a tab label, accordion pane title, etc., this specifies the tooltip to appear when the mouse is hovered over that text.

type

Corresponds to the native HTML <input> element's attribute.

value

Corresponds to the native HTML <input> element's attribute.

Methods

__onClick(e)

Internal function to divert the real click onto the hidden INPUT that has a native default action associated with it

Parameter Type Description
e Event
Returns:boolean
_applyAttributes()
Defined by dijit/_WidgetBase

Step during widget creation to copy widget attributes to the DOM according to attributeMap and _setXXXAttr objects, and also to call custom _setXXXAttr() methods.

Skips over blank/false attribute values, unless they were explicitly specified as parameters to the widget, since those are the default anyway, and setting tabIndex="" is different than not setting tabIndex at all.

For backwards-compatibility reasons attributeMap overrides _setXXXAttr when _setXXXAttr is a hash/string/array, but _setXXXAttr as a functions override attributeMap.

_attach(node,type,func)
Defined by dijit/_AttachMixin

Roughly corresponding to dojo/on, this is the default function for processing a data-dojo-attach-event. Meant to attach to DOMNodes, not to widgets.

Parameter Type Description
node DOMNode

The node to setup a listener on.

type String

Event name like "click".

func undefined
Returns:undefined
_attachTemplateNodes(rootNode)
Defined by dijit/_AttachMixin

Iterate through the dom nodes and attach functions and nodes accordingly.

  • dojoAttachPoint/data-dojo-attach-point
  • dojoAttachEvent/data-dojo-attach-event
Parameter Type Description
rootNode DomNode

The node to search for properties. All descendants will be searched.

_attrToDom(attr,value,commands)
Defined by dijit/_WidgetBase

Reflect a widget attribute (title, tabIndex, duration etc.) to the widget DOM, as specified by commands parameter. If commands isn't specified then it's looked up from attributeMap. Note some attributes like "type" cannot be processed this way as they are not mutable.

Parameter Type Description
attr String

Name of member variable (ex: "focusNode" maps to this.focusNode) pointing to DOMNode inside the widget, or alternately pointing to a subwidget

value String
commands Object
Optional
_beforeFillContent()
Defined by dijit/_AttachMixin
_changeAttrValue(name,value)
Defined by dojo/Stateful

Internal helper for directly changing an attribute value.

Directly change the value of an attribute on an object, bypassing any accessor setter. Also handles the calling of watch and emitting events. It is designed to be used by descendant class when there are two values of attributes that are linked, but calling .set() is not appropriate.

Parameter Type Description
name String

The property to set.

value Mixed

The value to set in the property.

Returns:function

Internal helper for directly changing an attribute value.

_cssMouseEvent(event)

Handler for CSS event on this.domNode. Sets hovering and active properties depending on mouse state, which triggers _setStateClass() to set appropriate CSS classes for this.domNode.

Parameter Type Description
event Event
_detachTemplateNodes()
Defined by dijit/_AttachMixin

Detach and clean up the attachments made in _attachtempalteNodes.

_escapeValue(val)

Parameter Type Description
val String
Returns:undefined
_fillContent()
Defined by dijit/form/CheckBox
_get(name)
Defined by dijit/_WidgetBase

Helper function to get value for specified property stored by this._set(), i.e. for properties with custom setters. Used mainly by custom getters.

_getRelatedWidgets()
Returns:Array
_getSubmitValue(value)
Parameter Type Description
value String
Returns:string
_getValueAttr()
Defined by dijit/form/CheckBox

Returns:undefined
_handleOnChange(newValue,priorityChange)

Called when the value of the widget is set. Calls onChange() if appropriate

Parameter Type Description
newValue anything

the new value

_setStateClass()

Update the visual state of the widget by setting the css classes on this.domNode (or this.stateNode if defined) by combining this.baseClass with various suffixes that represent the current widget state(s).

In the case where a widget has multiple states, it sets the class based on all possible combinations. For example, an invalid form widget that is being hovered will be "dijitInput dijitInputInvalid dijitInputHover dijitInputInvalidHover".

The widget may have one or more of the following states, determined by this.state, this.checked, this.valid, and this.selected:

  • Error - ValidationTextBox sets this.state to "Error" if the current input value is invalid
  • Incomplete - ValidationTextBox sets this.state to "Incomplete" if the current input value is not finished yet
  • Checked - ex: a checkmark or a ToggleButton in a checked state, will have this.checked==true
  • Selected - ex: currently selected tab will have this.selected==true

In addition, it may have one or more of the following states, based on this.disabled and flags set in _onMouse (this.active, this.hovering) and from focus manager (this.focused):

  • Disabled - if the widget is disabled
  • Active - if the mouse (or space/enter key?) is being pressed down
  • Focused - if the widget has focus
  • Hover - if the mouse is over the widget
_setStyleAttr(value)
Defined by dijit/_WidgetBase

Sets the style attribute of the widget according to value, which is either a hash like {height: "5px", width: "3px"} or a plain string

Determines which node to set the style on based on style setting in attributeMap.

Parameter Type Description
value String | Object
_setTextDirAttr(textDir)

Parameter Type Description
textDir String
_setValueAttr(newValue,priorityChange)
Defined by dijit/form/CheckBox

Handler for value= attribute to constructor, and also calls to set('value', val).

During initialization, just saves as attribute to the <input type=checkbox>.

After initialization, when passed a boolean, controls whether or not the CheckBox is checked. If passed a string, changes the value attribute of the CheckBox (the one specified as "value" when the CheckBox was constructed (ex: <input data-dojo-type="dijit/CheckBox" value="chicken">).

widget.set('value', string) will check the checkbox and change the value to the specified string.

widget.set('value', boolean) will change the checked state.

Parameter Type Description

Handler for hover/active mouse event on widget's subnode

Parameter Type Description
node undefined
clazz undefined
evt undefined
_trackMouseState(node,clazz)

Track mouse/focus events on specified node and set CSS class on that node to indicate current state. Usually not called directly, but via cssStateNodes attribute.

Given class=foo, will set the following CSS class on the node

  • fooActive: if the user is currently pressing down the mouse button while over the node
  • fooHover: if the user is hovering the mouse over the node, but not pressing down a button
  • fooFocus: if the node is focused

Note that it won't set any classes if the widget is disabled.

Parameter Type Description
node DomNode

Should be a sub-node of the widget, not the top node (this.domNode), since the top node is handled specially and automatically just by mixing in this class.

clazz String

CSS class name (ex: dijitSliderUpArrow)

attr(name,value)
Defined by dijit/_Widget

This method is deprecated, use get() or set() directly.

Parameter Type Description
name String | Object

The property to get or set. If an object is passed here and not a string, its keys are used as names of attributes to be set and the value of the object as values to set in the widget.

value Object
Optional

Optional. If provided, attr() operates as a setter. If omitted, the current value of the named property is returned.

Returns:undefined
buildRendering()
Defined by dijit/_WidgetBase

Construct the UI for this widget, setting this.domNode. Most widgets will mixin dijit._TemplatedMixin, which implements this method.

compare(val1,val2)

Compare 2 values (as returned by get('value') for this widget).

Parameter Type Description
val1 anything
val2 anything
Returns:number
connect(obj,event,method)
Defined by dijit/_WidgetBase

Deprecated, will be removed in 2.0, use this.own(on(...)) or this.own(aspect.after(...)) instead.

Connects specified obj/event to specified method of this object and registers for disconnect() on widget destroy.

Provide widget-specific analog to dojo.connect, except with the implicit use of this widget as the target object. Events connected with this.connect are disconnected upon destruction.

Parameter Type Description
obj Object | null
event String | Function
method String | Function
Returns:any | undefined

A handle that can be passed to disconnect in order to disconnect before the widget is destroyed.

Examples

Example 1

var btn = new Button();
// when foo.bar() is called, call the listener we're going to
// provide in the scope of btn
btn.connect(foo, "bar", function(){
    console.debug(this.toString());
});
create(params,srcNodeRef)
Defined by dijit/_WidgetBase

Kick off the life-cycle of a widget

Create calls a number of widget methods (postMixInProperties, buildRendering, postCreate, etc.), some of which of you'll want to override. See http://dojotoolkit.org/reference-guide/dijit/_WidgetBase.html for a discussion of the widget creation lifecycle.

Of course, adventurous developers could override create entirely, but this should only be done as a last resort.

Parameter Type Description
params Object | null

Hash of initialization parameters for widget, including scalar values (like title, duration etc.) and functions, typically callbacks like onClick. The hash can contain any of the widget's properties, excluding read-only properties.

srcNodeRef DOMNode | String
Optional

If a srcNodeRef (DOM node) is specified:

  • use srcNodeRef.innerHTML as my contents
  • if this is a behavioral widget then apply behavior to that srcNodeRef
  • otherwise, replace srcNodeRef with my generated DOM tree
defer(fcn,delay)
Defined by dijit/_WidgetBase

Wrapper to setTimeout to avoid deferred functions executing after the originating widget has been destroyed. Returns an object handle with a remove method (that returns null) (replaces clearTimeout).

Parameter Type Description
fcn Function

Function reference.

delay Number
Optional

Delay, defaults to 0.

Returns:object
destroy(preserveDom)
Defined by dijit/_WidgetBase

Destroy this widget, but not its descendants. Descendants means widgets inside of this.containerNode. 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, assuming those widgets exist inside of this.domNode but outside of this.containerNode.

For 2.0 it's planned that this method will also destroy descendant widgets, so apps should not depend on the current ability to destroy a widget without destroying its descendants. Generally they should use destroyRecursive() for widgets with children.

Parameter Type Description
preserveDom Boolean

If true, this method will leave the original DOM structure alone. Note: This will not yet work with _TemplatedMixin widgets

destroyDescendants(preserveDom)
Defined by dijit/_WidgetBase

Recursively destroy the children of this widget and their descendants.

Parameter Type Description
preserveDom Boolean
Optional

If true, the preserveDom attribute is passed to all descendant widget's .destroy() method. Not for use with _Templated widgets.

destroyRecursive(preserveDom)
Defined by dijit/_WidgetBase

Destroy this widget and its descendants

This is the generic "destructor" function that all widget users should call to cleanly discard with a widget. Once a widget is destroyed, it is removed from the manager object.

Parameter Type Description
preserveDom Boolean
Optional

If true, this method will leave the original DOM structure alone of descendant Widgets. Note: This will NOT work with dijit._TemplatedMixin widgets.

destroyRendering(preserveDom)
Defined by dijit/_WidgetBase

Destroys the DOM nodes associated with this widget.

Parameter Type Description
preserveDom Boolean
Optional

If true, this method will leave the original DOM structure alone during tear-down. Note: this will not work with _Templated widgets yet.

disconnect(handle)
Defined by dijit/_WidgetBase

Deprecated, will be removed in 2.0, use handle.remove() instead.

Disconnects handle created by connect.

Parameter Type Description
handle undefined
emit(type,eventObj,callbackArgs)
Defined by dijit/_WidgetBase

Used by widgets to signal that a synthetic event occurred, ex:

myWidget.emit("attrmodified-selectedChildWidget", {}).

Emits an event on this.domNode named type.toLowerCase(), based on eventObj. Also calls onType() method, if present, and returns value from that method. By default passes eventObj to callback, but will pass callbackArgs instead, if specified. Modifies eventObj by adding missing parameters (bubbles, cancelable, widget).

Parameter Type Description
type String
eventObj Object
Optional
callbackArgs Array
Optional
Returns:undefined
focus()

Put focus on this widget

get(name)
Defined by dijit/_WidgetBase

Get a property from a widget.

Get a named property from a widget. The property may potentially be retrieved via a getter method. If no getter is defined, this just retrieves the object's property.

For example, if the widget has properties foo and bar and a method named _getFooAttr(), calling: myWidget.get("foo") would be equivalent to calling widget._getFooAttr() and myWidget.get("bar") would be equivalent to the expression widget.bar2

Parameter Type Description
name undefined

The property to get.

Returns:undefined
getChildren()
Defined by dijit/_WidgetBase

Returns all direct children of this widget, i.e. all widgets underneath this.containerNode whose parent is this widget. Note that it does not return all descendants, but rather just 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 that the array returned is a simple array. Application code should not assume existence of methods like forEach().

Returns:Array
getDescendants()
Defined by dijit/_Widget

Returns all the widgets contained by this, i.e., all widgets underneath this.containerNode. This method should generally be avoided as it returns widgets declared in templates, which are supposed to be internal/hidden, but it's left here for back-compat reasons.

Returns:Array
getParent()
Defined by dijit/_WidgetBase

Returns the parent widget of this widget.

Returns:undefined
getValue()

Deprecated. Use get('value') instead.

Returns:undefined
isFocusable()
Defined by dijit/_WidgetBase

Return true if this widget can currently be focused and false if not

Returns:undefined
isLeftToRight()
Defined by dijit/_WidgetBase

Return this widget's explicit or implicit orientation (true for LTR, false for RTL)

Returns:undefined
on(type,func)
Defined by dijit/_Widget
Parameter Type Description
type String | Function

protected

func Function
Returns:undefined
own()
Defined by dijit/Destroyable

Track specified handles and remove/destroy them when this instance is destroyed, unless they were already removed/destroyed manually.

Returns:any | undefined

The array of specified handles, so you can do for example:

var handle = this.own(on(...))[0];
placeAt(reference,position)
Defined by dijit/_WidgetBase

Place this widget somewhere in the DOM based on standard domConstruct.place() conventions.

A convenience function provided in all _Widgets, providing a simple shorthand mechanism to put an existing (or newly created) Widget somewhere in the dom, and allow chaining.

Parameter Type Description
reference String | DomNode | DocumentFragment | dijit/_WidgetBase

Widget, DOMNode, DocumentFragment, or id of widget or DOMNode

position String | Int
Optional

If reference is a widget (or id of widget), and that widget has an ".addChild" method, it will be called passing this widget instance into that method, supplying the optional position index passed. In this case position (if specified) should be an integer.

If reference is a DOMNode (or id matching a DOMNode but not a widget), the position argument can be a numeric index or a string "first", "last", "before", or "after", same as dojo/dom-construct::place().

Returns:dijit/_WidgetBase | function

Provides a useful return of the newly created dijit._Widget instance so you can "chain" this function by instantiating, placing, then saving the return value to a variable.

Examples

Example 1

// create a Button with no srcNodeRef, and place it in the body:
var button = new Button({ label:"click" }).placeAt(win.body());
// now, 'button' is still the widget reference to the newly created button
button.on("click", function(e){ console.log('click'); }));

Example 2

// create a button out of a node with id="src" and append it to id="wrapper":
var button = new Button({},"src").placeAt("wrapper");

Example 3

// place a new button as the first element of some div
var button = new Button({ label:"click" }).placeAt("wrapper","first");

Example 4

// create a contentpane and add it to a TabContainer
var tc = dijit.byId("myTabs");
new ContentPane({ href:"foo.html", title:"Wow!" }).placeAt(tc)
postCreate()
Defined by dijit/_Widget
postMixInProperties()
Defined by dijit/form/CheckBox
postscript(params,srcNodeRef)
Defined by dijit/_WidgetBase

Kicks off widget instantiation. See create() for details.

Parameter Type Description
params Object
Optional
srcNodeRef DomNode | String
reset()

Reset the widget's value to what it was at initialization time

set(name,value)
Defined by dijit/_WidgetBase

Set a property on a widget

Sets named properties on a widget which may potentially be handled by a setter in the widget.

For example, if the widget has properties foo and bar and a method named _setFooAttr(), calling myWidget.set("foo", "Howdy!") would be equivalent to calling widget._setFooAttr("Howdy!") and myWidget.set("bar", 3) would be equivalent to the statement widget.bar = 3;

set() may also be called with a hash of name/value pairs, ex:

myWidget.set({
    foo: "Howdy",
    bar: 3
});

This is equivalent to calling set(foo, "Howdy") and set(bar, 3)

Parameter Type Description
name undefined

The property to set.

value undefined

The value to set in the property.

Returns:function | string

Set a property on a widget

setAttribute(attr,value)
Defined by dijit/_Widget

Deprecated. Use set() instead.

Parameter Type Description

Deprecated. Use set('checked', true/false) instead.

Parameter Type Description
checked Boolean
setDisabled(disabled)

Deprecated. Use set('disabled', ...) instead.

Parameter Type Description
disabled Boolean
setLabel(content)
Defined by dijit/form/Button

Deprecated. Use set('label', ...) instead.

Parameter Type Description
content String
setValue(value)

Deprecated. Use set('value', ...) instead.

Parameter Type Description
value String
startup()
Defined by dijit/_WidgetBase

Processing after the DOM fragment is added to the document

Called after a 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.

subscribe(t,method)
Defined by dijit/_WidgetBase

Deprecated, will be removed in 2.0, use this.own(topic.subscribe()) instead.

Subscribes to the specified topic and calls the specified method of this object and registers for unsubscribe() on widget destroy.

Provide widget-specific analog to dojo.subscribe, except with the implicit use of this widget as the target object.

Parameter Type Description
t String

The topic

method Function

The callback

Returns:undefined

Examples

Example 1

var btn = new Button();
// when /my/topic is published, this button changes its label to
// be the parameter of the topic.
btn.subscribe("/my/topic", function(v){
    this.set("label", v);
});
toString()
Defined by dijit/_WidgetBase

Returns a string that represents the widget.

When a widget is cast to a string, this method will be used to generate the output. Currently, it does not implement any sort of reversible serialization.

Returns:string
uninitialize()
Defined by dijit/_WidgetBase

Deprecated. Override destroy() instead to implement custom widget tear-down behavior.

Returns:boolean
unsubscribe(handle)
Defined by dijit/_WidgetBase

Deprecated, will be removed in 2.0, use handle.remove() instead.

Unsubscribes handle created by this.subscribe. Also removes handle from this widget's list of subscriptions

Parameter Type Description
handle Object
watch(name,callback)
Defined by dojo/Stateful

Watches a property for changes

Parameter Type Description
name String
Optional

Indicates the property to watch. This is optional (the callback may be the only parameter), and if omitted, all the properties will be watched

callback Function

The function to execute when the property changes. This will be called after the property has been changed. The callback will be called with the |this| set to the instance, the first argument as the name of the property, the second argument as the old value and the third argument as the new value.

Returns:any | object

An object handle for the watch. The unwatch method of this object can be used to discontinue watching this property:

var watchHandle = obj.watch("foo", callback);
watchHandle.unwatch(); // callback won't be called now
