goog.ui.emoji.EmojiPaletteRenderer

Builds the inner contents of a palette item out of sprite metadata.

Overrides goog.ui.ControlRenderer#canDecorate to always return false.

Returns a table cell element (or equivalent) that wraps the given palette item (which must be a DOM node).

Returns the palette items arranged in a table wrapped in a DIV, with the renderer's own CSS class and additional state-specific classes applied to it.

Returns the given items in a table with size.width columns and size.height rows. If the table is too big, empty cells will be created as needed. If the table is too small, the items that don't fit will not be rendered.

Creates a palette item from the given emoji data.

Returns a table row element (or equivalent) that wraps the given cells.

Returns a table element (or equivalent) that wraps the given rows.

Overrides goog.ui.ControlRenderer#decorate to be a no-op, since palettes don't support the decorate flow (for now).

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.

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

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

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

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

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

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.

Returns the item corresponding to the given node, or null if the node is neither a palette cell nor part of a palette item.

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.

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

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.

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.

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

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.

Updates the highlight styling of the palette cell containing the given node based on the value of the Boolean argument.

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 goog.ui.Control#enterDocument.

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

Updates the selection styling of the palette cell containing the given node based on the value of the Boolean argument.

Allows or disallows text selection within the control's DOM.

Sets the element's ARIA label. This should be overriden by subclasses that don't apply the role directly on control.element_.

Sets the element's ARIA role.

Sets the element's ARIA attributes, including distinguishing between universally supported ARIA properties and ARIA states that are only supported by certain ARIA roles. Only attributes which are initialized to be true will be set.

Overrides goog.ui.ControlRenderer#setContent for palettes. Locates the HTML table representing the palette grid, and replaces the contents of each cell with a new element from the array of nodes passed as the second argument. If the new content has too many items the table will have more rows added to fit, if there are less items than the table has cells, then the left over cells will be empty.

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

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.

Updates the appearance of the control in response to a state change.

Shows or hides the element.

Modifies a palette item containing an animated emoji, in response to the animated emoji being successfully downloaded.

Updates the element's ARIA (accessibility) attributes , including distinguishing between universally supported ARIA properties and ARIA states that are only supported by certain ARIA roles.
