Class RapidContext.Widget.TabContainer

.Widget.TabContainer(attrs, …childopt) → {Widget}

The tab container widget class. Used to provide a set of tabbed pages, where the user can switch page freely. Internally it uses a <div> HTML element containing Pane widgets that are hidden and shown according to the page transitions. If a child Pane widget is pageCloseable, a close button will be available on the tab label.

RapidContext.Widget

Methods

addAll(…child)

Adds one or more children to this widget. This method will flatten any arrays among the arguments and ignores any null or undefined arguments. Any DOM nodes or widgets will be added to the end, and other objects will be converted to a text node first. Subclasses should normally override the addChildNode() method instead of this one, since that is the basis for DOM node insertion.

Parameters:

Name	Type	Attributes	Description
`child`	{string\|Node\|Array}	<repeatable>	the children to add

Inherited From:

RapidContext.Widget#addAll

Source:

RapidContext_Widget.js, line 581

addChildNode(child)

Adds a single child page widget to this widget. The child widget should be a RapidContext.Widget.Pane widget, or it will be added to a new one.

Parameters:

Name	Type	Description
`child`	{Widget}	the page widget to add

Overrides:

RapidContext.Widget#addChildNode

See:

RapidContext.Widget.Pane

Source:

RapidContext_Widget_TabContainer.js, line 114

addClass(…cls)

Adds the specified CSS class names to this HTML DOM node.

Parameters:

Name	Type	Attributes	Description
`cls`	{string\|Array}	<repeatable>	the CSS class names to add

Inherited From:

RapidContext.Widget#addClass

Source:

RapidContext_Widget.js, line 343

animate(opts)

Performs a visual effect animation on this widget. This is implemented using the MochiKit.Visual effect package. All options sent to this function will be passed on to the appropriate MochiKit.Visual function.

Parameters:

Name Type Description

opts

{Object}

the visual effect options

Properties

Name	Type	Description
`effect`	{string}	the MochiKit.Visual effect name
`queue`	{string}	the MochiKit.Visual queue handling, defaults to "replace" and a unique scope for each widget (see `MochiKit.Visual` for full options)

Inherited From:

RapidContext.Widget#animate

Deprecated:

Use CSS animations instead.

Example:

widget.animate({ effect: "fade", duration: 0.5 });
widget.animate({ effect: "Move", transition: "spring", y: 300 });

Source:

RapidContext_Widget.js, line 502

blurAll()

Blurs (unfocuses) this DOM node and all relevant child nodes. This function will recursively blur all <a>, <button>, <input>, <textarea> and <select> child nodes found.

Inherited From:: RapidContext.Widget#blurAll
Source:: RapidContext_Widget.js, line 521

destroy()

The internal widget destructor function. This method should only be called by destroyWidget() and may be overridden by subclasses. By default this method does nothing.

Inherited From:: RapidContext.Widget#destroy
Source:: RapidContext_Widget.js, line 198

disable()

Disables this widget if it was previously enabled. This method is equivalent to calling setAttrs({ disabled: true }).

Inherited From:: RapidContext.Widget#disable
Source:: RapidContext_Widget.js, line 434

emit(event, optsopt) → {boolean}

Dispatches a single event from this DOM node. Also creates a new CustomEvent instance if needed.

Parameters:

Name Type Attributes Description

event {string/Event} the event type name or instance

opts

{Object}

the event options

Properties

Name	Type	Attributes	Default	Description
`async`	{boolean}	<optional>	true	the async dispatch flag
`bubbles`	{boolean}	<optional>		the event bubbles flag
`cancelable`	{boolean}	<optional>		the cancellable event flag
`detail`	{Object}	<optional>		the additional event details

Returns:

{boolean} true if event was async or not cancelled

Inherited From:

RapidContext.UI.Event#emit

Source:

rapidcontext/ui/event.mjs, line 26

enable()

Enables this widget if it was previously disabled. This is equivalent to calling setAttrs({ disabled: false }).

Inherited From:: RapidContext.Widget#enable
Source:: RapidContext_Widget.js, line 426

getChildNodes() → {Array}

Returns an array with all child pane widgets. Note that the array is a real JavaScript array, not a dynamic NodeList.

Returns:: {Array} the array of child DOM nodes
Overrides:: RapidContext.Widget#getChildNodes
Source:: RapidContext_Widget_TabContainer.js, line 101

hasClass(…cls) → {boolean}

Checks if this HTML DOM node has the specified CSS class names. Note that more than one CSS class name may be checked, in which case all must be present.

Parameters:

Name	Type	Attributes	Description
`cls`	{string\|Array}	<repeatable>	the CSS class names to check

Returns:

{boolean} true if all CSS classes were present, or false otherwise

Inherited From:

RapidContext.Widget#hasClass

Source:

RapidContext_Widget.js, line 325

hide()

Hides this widget node if it was previously visible. This method is equivalent to calling setAttrs({ hidden: true }). It is safe for all types of widgets, since it only adds the widgetHidden CSS class instead of setting the display style property.

Inherited From:: RapidContext.Widget#hide
Source:: RapidContext_Widget.js, line 480

isDisabled() → {boolean}

Checks if this widget is disabled. This method checks both the "widgetDisabled" CSS class and the disabled property. Changes to the disabled status can be made with enable(), disable() or setAttrs().

Returns:: {boolean} true if the widget is disabled, or false otherwise
Inherited From:: RapidContext.Widget#isDisabled
Source:: RapidContext_Widget.js, line 405

isHidden() → {boolean}

Checks if this widget node is hidden. This method checks for the existence of the widgetHidden CSS class. It does NOT check the actual widget visibility (the display style property set by animations for example).

Returns:: {boolean} true if the widget is hidden, or false otherwise
Inherited From:: RapidContext.Widget#isHidden
Source:: RapidContext_Widget.js, line 447

off(eventopt, selectoropt, listeneropt) → {Node}

Removes one or more previously attached event listeners. If no event details or listeners are specified, all matching handlers are removed.

Parameters:

Name	Type	Attributes	Description
`event`	{string}	<optional>	the event type name (or space separated names)
`selector`	{string}	<optional>	the CSS selector to match for event target
`listener`	{function}	<optional>	the event handler function (or `false`)

Returns:

{Node} the input DOM node (for chaining calls)

Inherited From:

RapidContext.UI.Event#once

Source:

removeAll()

Removes all children to this widget. This method will also destroy and child widgets and disconnect all signal listeners. This method uses the getChildNodes() and removeChildNode() methods to find and remove the individual child nodes.

Inherited From:: RapidContext.Widget#removeAll
Source:: RapidContext_Widget.js, line 593

removeChildNode(child)

Removes a single child DOM node from this widget. This method is sometimes overridden by child widgets in order to hide or control intermediate DOM nodes required by the widget.

Note that this method will NOT destroy the removed child widget, so care must be taken to ensure proper child widget destruction.

Parameters:

Name	Type	Description
`child`	{Widget\|Node}	the DOM node to remove

Overrides:

RapidContext.Widget#removeChildNode

Source:

RapidContext_Widget_TabContainer.js, line 145

removeClass(…cls)

Parameters:

Name	Type	Attributes	Description
`cls`	{string\|Array}	<repeatable>	the CSS class names to remove

Inherited From:

RapidContext.Widget#removeClass

Source:

RapidContext_Widget.js, line 363

Source:

RapidContext_Widget_TabContainer.js, line 195

`disabled`	{boolean}	<optional>	the disabled widget flag

Inherited From:

RapidContext.Widget#setStyle

Example:

widget.setStyle({ "font-size": "bold", "color": "red" });
