Class s7sdk.favorites.AddFavoriteButton

Extends s7sdk.common.Button, s7sdk.common.TwoStateButton.

The AddFavoriteButton is a toggle button normally used inside FavoritesMenu component. This button is designed to activate or deactivate "add favorite" operation mode in favorites feature.

This component does not currently read any modifiers.

Defining the Appearance using CSS

You can define the appearance of the AddFavoriteButton component using CSS rules. All HTML5 Viewer SDK components use class selectors for styling. You can style the body of the AddFavoriteButton component by using the .s7addfavoritebutton class selector. The styles that are associated with this class selector are applied to all instances of the AddFavoriteButton component. You can style particular instances by prefixing the class rule with the instance #id. For example, styling rules for #myComp.s7addfavoritebutton are applied only to the particular AddFavoriteButton instance.

CSS Class	Attribute Selector	Description
`.s7addfavoritebutton`	`selected=[true\|false]` `state=[up\|over\|down\|disabled]`	Define appearance of the `AddFavoriteButton` component. Each state can be styled independently.
`.s7tooltip`	(None)	A global class selector that defines appearance for the tooltips. To disable tooltips set the `display` style to `none`.

Localizable Symbols

AddFavoriteButton also has text symbols that you can localize either in a preset or in the viewer page though the mechanisms provided by the ParameterManager. For more information on localization consult the ParameterManager API documentation and HTML5 Viewers SDK User Guide.

Symbol	Description
`AddFavoriteButton.TOOLTIP_SELECTED`	Tooltip for selected button state
`AddFavoriteButton.TOOLTIP_UNSELECTED`	Tooltip for unselected button state

Example Code
This example demonstrates how to use favorites components in a simple viewer. In this example a PageView, ThumbnailGridView,
Swatches and TableOfContents component are put together to construct a simple eCatalog viewer. On top of that, we are adding a set
of components to support "favorites" feature: FavoritesMany is added to the top ControlBar with the 3 buttons: AddFavoriteButton, 
RemoveFavoriteButton and ViewAllFavoritesButton. FavoritesEffect component is attached to PageView to support rendering and editing
of favorites. FavoritesView component becomes available when user clicks on ViewAllFavoritesButton button and allows to review all
available favorites.

The code below does the following:

The Scene7 HTML5 SDK is linked to the page and the required s7sdk components are included in the document head.
CSS Styles are defined in the document head to control the appearance of the SDK components.
The s7sdk.Util.init() method is called to initialize the SDK.
A ParameterManager object is created to handle component modifiers for the viewer.
An initViewer() function is defined. This function initializes a couple of modifiers (hard coded for example purposes),
then creates the component objects required for this simple example. The initViewer() function also adds event listeners
that designate functions to handle relevant component events (which might be dispatched by the components as a result of
user interactions, changes in a component's state, etc.).
Handler functions are defined to respond to the component event listeners added in the initViewer() function.
An event listener is added to the ParameterManager object that designates the initViewer() function as the handler
to call when the Scene7 SDK is loaded and ready.
Finally, the init() method is called on the ParameterManager object to start the viewer.
