Parameters |
| ||||||||
Returns |
|
this.enableClassName( control, className, enable ) → void
void
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.

this.enableExtraClassName( control, className, enable ) → void
void
Updates the control's DOM by adding or removing the specified extra class name to/from its element.

Parameters |

this.getAriaRole() → (goog.a11y.aria.Role|undefined)
(goog.a11y.aria.Role|undefined)
Returns the ARIA role to be applied to the control. See http://wiki/Main/ARIA for more info.

Parameters | None. | ||
Returns |
|
this.getClassForState( state ) → (string|undefined)
(string|undefined)
Takes a single goog.ui.Component.State
, and returns the
corresponding CSS class name (null if none).
Defined by | |||||
---|---|---|---|---|---|
Parameters |
| ||||
Returns |
|
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_
.

Parameters |
| ||||
Returns |
|
Takes a bit mask of 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 getClassForState
method to
generate each state-specific class.

Parameters |
| ||||
Returns |
|
this.getContentElement( element ) → (Element|null)
(Element|null)
Takes the control's root element and returns the parent element of the control's contents. Since by default controls are rendered as a single DIV, the default implementation returns the element itself. Subclasses with more complex DOM structures must override this method as needed.

this.getGridOffsetY( palette, y ) → number
number
Returns the y offset in to the grid for the given mouse y position.
Parameters |
| ||||||||
---|---|---|---|---|---|---|---|---|---|
Returns |
|
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.

Parameters | None. | ||
Returns |
|
this.getKeyEventTarget( control ) → (Element|null)
(Element|null)
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 | |||||

Parameters |
| ||||
Returns |
|
this.getMouseMoveElement( palette ) → (Element|null)
(Element|null)
Get the element to listen for mouse move events on.
Parameters |
| ||||
---|---|---|---|---|---|
Returns |
|
this.getStateFromClass( className ) → goog.ui.Component.State
goog.ui.Component.State
Takes a single CSS class name which may represent a component state, and returns the corresponding component state (0x00 if none).
Defined by | |||||
---|---|---|---|---|---|
Parameters |
| ||||
Returns |
|
this.getStructuralCssClass() → string
string
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.
