Custom renderer for goog.ui.Buttons. This renderer supports the "primary action" style for buttons.

new PrimaryActionButtonRenderer()

Parameters	None.

Instance Methods

Returns true if this renderer can decorate the element. Overrides goog.ui.ButtonRenderer#canDecorate by returning true if the element is a DIV, false otherwise.

Defined by

goog.ui.CustomButtonRenderer

Overrides

goog.ui.ControlRenderer

Parameters

`element`	`(Element\|null)`
	Element to decorate.

Returns

boolean

Whether the renderer can decorate the element.

VIEW SOURCE

Takes a text caption or existing DOM structure, and returns the content wrapped in a pseudo-rounded-corner box. Creates the following DOM structure:

<div class="goog-inline-block goog-button-base-outer-box">
  <div class="goog-inline-block goog-button-base-inner-box">
    <div class="goog-button-base-pos">
      <div class="goog-button-base-top-shadow">&nbsp;</div>
      <div class="goog-button-base-content">Contents...</div>
    </div>
  </div>
</div>

Used by both #createDom and #decorate. To be overridden by subclasses.

Defined by

goog.ui.style.app.ButtonRenderer

Overrides

goog.ui.CustomButtonRenderer

Parameters

`content`	`(string\|Node\|Array<Node>\|NodeList<Node>\|null)`
	Text caption or DOM structure to wrap in a box.
`dom`	`(goog.dom.DomHelper\|null)`
	DOM helper, used for document interaction.

Returns

Element

Pseudo-rounded-corner box containing the content.

VIEW SOURCE

Returns the button's contents wrapped in the following DOM structure:

<div class="goog-inline-block goog-custom-button">
  <div class="goog-inline-block goog-custom-button-outer-box">
    <div class="goog-inline-block goog-custom-button-inner-box">

</div>

Overrides goog.ui.ButtonRenderer#createDom.

Defined by

goog.ui.CustomButtonRenderer

Overrides

goog.ui.ButtonRenderer

Parameters

`control`	`(goog.ui.Control\|null)`
	goog.ui.Button to render.

Returns

Element

Root element for the button.

VIEW SOURCE

Takes an existing element and decorates it with the custom button control. Initializes the control's ID, content, tooltip, value, and state based on the ID of the element, its child nodes, and its CSS classes, respectively. Returns the element. Overrides goog.ui.ButtonRenderer#decorate.

Defined by

goog.ui.CustomButtonRenderer

Overrides

goog.ui.ButtonRenderer

Parameters

`control`	`(goog.ui.Control\|null)`
	Button instance to decorate the element.
`element`	`(Element\|null)`
	Element to decorate.

Returns

(Element|null)

Decorated element.

VIEW SOURCE

Updates the control's DOM by adding or removing the specified class name to/from its root element. May add additional combined classes as needed in IE6 and lower. Because of this, subclasses should use this method when modifying class names on the control's root element.

Defined by

goog.ui.ControlRenderer

Parameters

`control`	`(goog.ui.Control\|Element\|null)`
	Control instance (or root element) to be updated.
`className`	`string`
	CSS class name to add or remove.
`enable`	`boolean`
	Whether to add or remove the class name.

VIEW SOURCE

Updates the control's DOM by adding or removing the specified extra class name to/from its element.

Defined by

goog.ui.ControlRenderer

Parameters

`control`	`(goog.ui.Control\|null)`
	Control to be updated.
`className`	`string`
	CSS class name to add or remove.
`enable`	`boolean`
	Whether to add or remove the class name.

VIEW SOURCE

Returns the ARIA role to be applied to custom buttons.

Defined by

goog.ui.CustomButtonRenderer

Overrides

goog.ui.ButtonRenderer

Parameters

None.

Returns

(goog.a11y.aria.Role|undefined)

ARIA role.

VIEW SOURCE

Takes a single goog.ui.Component.State, and returns the corresponding CSS class name (null if none).

Defined by

goog.ui.ControlRenderer

Parameters

`state`	`goog.ui.Component.State`
	Component state.

Returns

(string|undefined)

CSS class representing the given state (undefined if none).

VIEW SOURCE

Returns all CSS class names applicable to the given control, based on its state. The return value is an array of strings containing

the renderer-specific CSS class returned by #getCssClass, followed by
the structural CSS class returned by getStructuralCssClass (if different from the renderer-specific CSS class), followed by
any state-specific classes returned by #getClassNamesForState, followed by
any extra classes returned by the control's `getExtraClassNames` method and
for IE6 and lower, additional combined classes from getAppliedCombinedClassNames_.

Since all controls have at least one renderer-specific CSS class name, this method is guaranteed to return an array of at least one element.

Defined by

goog.ui.ControlRenderer

Parameters

`control`	`(goog.ui.Control\|null)`
	Control whose CSS classes are to be returned.

Returns

Array<string>

Array of CSS class names applicable to the control.

VIEW SOURCE

Takes a bit mask of goog.ui.Component.States, and returns an array of the appropriate class names representing the given state, suitable to be applied to the root element of a component rendered using this renderer, or null if no state-specific classes need to be applied. This default implementation uses the renderer's getClassForState method to generate each state-specific class.

Defined by

goog.ui.ControlRenderer

Parameters

`state`	`number`
	Bit mask of component states.

Returns

Array<string>

Array of CSS class names representing the given state.

VIEW SOURCE

Takes the button's root element and returns the parent element of the button's contents. Overrides the superclass implementation by taking the nested DIV structure of custom buttons into account.

Defined by

goog.ui.style.app.ButtonRenderer

Overrides

goog.ui.CustomButtonRenderer

Parameters

`element`	`(Element\|null)`
	Root element of the button whose content element is to be returned.

Returns

(Element|null)

The button's content element (if any).

VIEW SOURCE

Returns the CSS class to be applied to the root element of components rendered using this renderer.

Overrides

goog.ui.style.app.ButtonRenderer

Parameters

None.

Returns

string

Renderer-specific CSS class.

VIEW SOURCE

Returns an array of combinations of classes to apply combined class names for in IE6 and below. See IE6_CLASS_COMBINATIONS for more detail. This method doesn't reference IE6_CLASS_COMBINATIONS so that it can be compiled out, but subclasses should return their IE6_CLASS_COMBINATIONS static constant instead.

Overrides

goog.ui.style.app.ButtonRenderer

Parameters

None.

Returns

Array<(Array<string>|null)>

Array of class name combinations.

VIEW SOURCE

Returns the element within the component's DOM that should receive keyboard focus (null if none). The default implementation returns the control's root element.

Defined by

goog.ui.ControlRenderer

Parameters

`control`	`(goog.ui.Control\|null)`
	Control whose key event target is to be returned.

Returns

(Element|null)

The key event target.

VIEW SOURCE

Takes a single CSS class name which may represent a component state, and returns the corresponding component state (0x00 if none).

Defined by

goog.ui.ControlRenderer

Parameters

`className`	`string`
	CSS class name, possibly representing a component state.

Returns

goog.ui.Component.State

state Component state corresponding to the given CSS class (0x00 if none).

VIEW SOURCE

Returns the name of a DOM structure-specific CSS class to be applied to the root element of all components rendered or decorated using this renderer. Unlike the class name returned by #getCssClass, the structural class name may be shared among different renderers that generate similar DOM structures. The structural class name also serves as the basis of derived class names used to identify and style structural elements of the control's DOM, as well as the basis for state-specific class names. The default implementation returns the same class name as #getCssClass, but subclasses are expected to override this method as needed.

Defined by

goog.ui.style.app.ButtonRenderer

Overrides

goog.ui.ControlRenderer

Parameters

None.

Returns

string

DOM structure-specific CSS class name (same as the renderer- specific CSS class name by default).

VIEW SOURCE

Takes a button's root element, and returns its tooltip text.

Defined by

Defined by

goog.ui.ButtonRenderer

Parameters
