goog.ui.ToolbarColorMenuButtonRenderer()
Toolbar-style renderer for {@link goog.ui.ColorMenuButton}s.
.canDecorate(element)
Inherited from goog.ui.CustomButtonRenderer
.
Returns true if this renderer can decorate the element. Overrides {@link goog.ui.ButtonRenderer#canDecorate} by returning true if the element is a DIV, false otherwise.
element
{Element
}
boolean
}
.createButton(content, dom)
Inherited from goog.ui.MenuButtonRenderer
.
Takes a text caption or existing DOM structure, and returns the content and a dropdown arrow element wrapped in a pseudo-rounded-corner box. Creates the following DOM structure:
content
{goog.ui.ControlContent
}
dom
{goog.dom.DomHelper
}
Element
}
.createCaption(content, dom)
Overrides the superclass implementation by wrapping the caption text or DOM structure in a color indicator element. Creates the following DOM structure:
content
{goog.ui.ControlContent
}
dom
{goog.dom.DomHelper
}
Element
}
.createDom(control)
Inherited from goog.ui.CustomButtonRenderer
.
Returns the button's contents wrapped in the following DOM structure:
Overrides {@link goog.ui.ButtonRenderer#createDom}.control
{goog.ui.Control
}
Element
}
.createDropdown(dom)
Inherited from goog.ui.MenuButtonRenderer
.
Returns an appropriately-styled DIV containing a dropdown arrow element. Creates the following DOM structure:
dom
{goog.dom.DomHelper
}
Element
}
.decorate(control, element)
Inherited from goog.ui.MenuButtonRenderer
.
Takes an element, decorates it with the menu button control, and returns the element. Overrides {@link goog.ui.CustomButtonRenderer#decorate} by looking for a child element that can be decorated by a menu, and if it finds one, decorates it and attaches it to the menu button.
control
{goog.ui.Control
}
element
{Element
}
Element
}
.enableClassName(control, className, enable)
Inherited from goog.ui.ControlRenderer
.
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.
control
{goog.ui.Control
|Element
}
className
{string
}
enable
{boolean
}
.enableExtraClassName(control, className, enable)
Inherited from goog.ui.ControlRenderer
.
Updates the control's DOM by adding or removing the specified extra class name to/from its element.
control
{goog.ui.Control
}
className
{string
}
enable
{boolean
}
.getAriaRole()
Inherited from goog.ui.CustomButtonRenderer
.
Returns the ARIA role to be applied to custom buttons.
goog.dom.a11y.Role
|undefined
}
.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
}
string
|undefined
}
.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
control
{goog.ui.Control
}
Array
.<string
>}
.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
}
Array
.<string
>}
.getContentElement(element)
Inherited from goog.ui.MenuButtonRenderer
.
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 menu buttons into account.
element
{Element
}
Element
}
.getCssClass()
Inherited from goog.ui.ToolbarMenuButtonRenderer
.
Returns the CSS class to be applied to the root element of menu buttons rendered using this renderer.
string
}
.getIe6ClassCombinations()
Inherited from goog.ui.ControlRenderer
.
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.
Array
.<Array
.<string
>>}
.getKeyEventTarget(control)
Inherited from goog.ui.ControlRenderer
.
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.
control
{goog.ui.Control
}
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
}
goog.ui.Component.State
}
.getStructuralCssClass()
Inherited from goog.ui.ControlRenderer
.
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.
string
}
.getTooltip(element)
Inherited from goog.ui.ButtonRenderer
.
Takes a button's root element, and returns its tooltip text.
element
{Element
}
string
|undefined
}
.getValue
Inherited from goog.ui.ButtonRenderer
.
Takes a button's root element, and returns the value associated with it. No-op in the base class.
element
{Element
}
string
|undefined
}
.hasBoxStructure(button, element)
[protected]Inherited from goog.ui.CustomButtonRenderer
.
Check if the button's element has a box structure.
button
{goog.ui.Button
}
element
{Element
}
boolean
}
.initializeDom(button)
Initializes the button's DOM when it enters the document. Overrides the superclass implementation by making sure the button's color indicator is initialized.
button
{goog.ui.Control
}
.isFocusable(control)
Inherited from goog.ui.ControlRenderer
.
Returns true if the control's key event target supports keyboard focus (based on its {@code tabIndex} attribute), false otherwise.
control
{goog.ui.Control
}
boolean
}
.setAllowTextSelection(element, allow)
Inherited from goog.ui.ControlRenderer

.setAriaRole(element, opt_preferredRole)
Inherited from goog.ui.ControlRenderer
.
Sets the element's ARIA role.
element
{Element
}
opt_preferredRole
{?goog.dom.a11y.Role
=}
.setAriaStates(control, element)
Inherited from goog.ui.ControlRenderer
.
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.
control
{!goog.ui.Control
}
element
{!Element
}
.setCollapsed(button, sides)
[protected]Inherited from goog.ui.ButtonRenderer
.
Collapses the border on one or both sides of the button, allowing it to be combined with the adjacent button(s), forming a single UI componenet with multiple targets.
button
{goog.ui.Button
}
sides
{number
}
.setContent(element, content)
Inherited from goog.ui.MenuButtonRenderer
.
Takes the menubutton's root element, and sets its content to the given text caption or DOM structure. Because the DOM structure of this button is conditional based on whether we need to work around FF2/RTL bugs, we override the default implementation to take this into account.
element
{Element
}
content
{goog.ui.ControlContent
}
.setFocusable(control, focusable)
Inherited from goog.ui.ControlRenderer
.
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.
control
{goog.ui.Control
}
focusable
{boolean
}
.setRightToLeft(element, rightToLeft)
Inherited from goog.ui.ControlRenderer
.
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.
