The goog.ui.RoundedTabRenderer Class

Default CSS class to be applied to the root element of components rendered by this renderer.

.canDecorate(element)

Returns true if this renderer can decorate the element, false otherwise. The default implementation always returns true.

`.createCaption(dom, caption)` [protected]

Creates a table row implementing the tab caption.

dom {goog.dom.DomHelper}: DOM helper to use for element construction.
caption {goog.ui.ControlContent}: Text caption or DOM structure to display as the tab's caption.
returns {Element}: Tab caption table row.

.createDom(tab)

Creates the tab's DOM structure, based on the containing tab bar's location relative to tab contents. For example, the DOM for a tab in a tab bar located above tab contents would look like this:

`.createEdge(dom, isTopEdge)` [protected]

Creates a table row implementing a rounded tab edge.

dom {goog.dom.DomHelper}: DOM helper to use for element construction.
isTopEdge {boolean}: Whether to create a top or bottom edge.
returns {Element}: Rounded tab edge table row.

`.createTab(dom, caption, location)` [protected]

Creates a table implementing a rounded corner tab.

dom {goog.dom.DomHelper}: DOM helper to use for element construction.
caption {goog.ui.ControlContent}: Text caption or DOM structure to display as the tab's caption.
location {goog.ui.TabBar.Location}: Tab bar location relative to the tab contents.
returns {Element}: Table implementing a rounded corner tab.

.decorate(tab, element)

Decorates the element with the tab. Overrides the superclass implementation by wrapping the tab's content in a table that implements rounded corners.

.enableClassName(control, className, enable)

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.

.enableExtraClassName(control, className, enable)

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

.getAriaRole()

Returns the ARIA role to be applied to the tab element. See http://wiki/Main/ARIA for more info.

`.getClassForState(state)` [protected]

Inherited from goog.ui.ControlRenderer .

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

state {goog.ui.Component.State}: Component state.
returns {string|undefined}: CSS class representing the given state (undefined if none).

`.getClassNames(control)` [protected]

Inherited from goog.ui.ControlRenderer .

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

control {goog.ui.Control}: Control whose CSS classes are to be returned.
returns {Array.<string>}: Array of CSS class names applicable to the control.

`.getClassNamesForState(state)` [protected]

Inherited from goog.ui.ControlRenderer .

Takes a bit mask of {@link goog.ui.Component.State}s, 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 {@link getClassForState} method to generate each state-specific class.

state {number}: Bit mask of component states.
returns {!Array.<string>}: Array of CSS class names representing the given state.

.getContentElement()

.getCssClass()

Returns the CSS class name to be applied to the root element of all tabs rendered or decorated using this renderer.

.getIe6ClassCombinations()

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

.getKeyEventTarget(control)

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.

`.getStateFromClass(className)` [protected]

Inherited from goog.ui.ControlRenderer .

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

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).

.getStructuralCssClass()

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 {@link #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 {@link #getCssClass}, but subclasses are expected to override this method as needed.

.getTooltip(element)

Takes a tab's root element, and returns its tooltip text, or the empty string if the element has no tooltip.

.initializeDom(control)

Initializes the control's DOM by configuring properties that can only be set after the DOM has entered the document. This implementation sets up BiDi and keyboard focus. Called from {@link goog.ui.Control#enterDocument}.

.isFocusable(control)

Returns true if the control's key event target supports keyboard focus (based on its {@code tabIndex} attribute), false otherwise.

.setAllowTextSelection(element, allow)

.setAriaRole(element, opt_preferredRole)

.setAriaStates(control, element)

Sets the element's ARIA states. An element does not need an ARIA role in order to have an ARIA state. Only states which are initialized to be true will be set.

.setContent(element, content)

Takes a control's root element, and sets its content to the given text caption or DOM structure. The default implementation replaces the children of the given element. Renderers that create more complex DOM structures must override this method accordingly.

.setFocusable(control, focusable)

Updates the control's key event target to make it focusable or non-focusable via its {@code tabIndex} attribute. Does nothing if the control doesn't support the {@code FOCUSED} state, or if it has no key event target.

.setRightToLeft(element, rightToLeft)

Applies special styling to/from the control's element if it is rendered right-to-left, and removes it if it is rendered left-to-right.

.setState(control, state, enable)

.setTooltip(element, tooltip)

Takes a tab's root element and a tooltip string, and updates the element with the new tooltip. If the new tooltip is null or undefined, sets the element's title to the empty string.

.setVisible(element, visible)

`.updateAriaState(element, state, enable)` [protected]

Inherited from goog.ui.ControlRenderer .

Updates the element's ARIA (accessibility) state.

element {Element}: Element whose ARIA state is to be updated.
state {goog.ui.Component.State}: Component state being enabled or disabled.
enable {boolean}: Whether the state is being enabled or disabled.
