Class s7sdk.common.ThumbnailPageButton

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

The ThumbnailPageButton is a two state button that is typically used for toggling between the PageView and ThumbnailGridView components in eCatalog applications. The selected state is automatically changed when user clicks/taps on the button. Alternatively, the state can be changed through setSelected() API.

The component can be added to the ControlBar and grouped with other UI components.

Currently this component does not support any modifiers.

Defining Appearance using CSS

You can define the appearance of the ThumbnailPageButton component using CSS rules. All HTML5 Viewer SDK components use class selectors for styling. You can style the body of the ThumbnailPageButton component by using the .s7thumbnailpagebutton class selector. The styles that are associated with this class selector are applied to all instances of the ThumbnailPageButton component. You can style particular instances by prefixing the class rule with the instance #id. For example, styling rules for #myComp.s7thumbnailpagebutton are applied only to the particular ThumbnailPageButton instance.

CSS Class	Attribute Selector	Description
`.s7thumbnailpagebutton`	`selected=[true\|false]` `state=[up\|over\|down\|disabled]`	Define appearance of `ThumbnailPageButton` for each state, independently for selected and unselected case.
`.s7tooltip`	(None)	A global class selector that defines appearance for the tooltips. To disable tooltips set the `display` style to `none`.

Localizable Symbols

ThumbnailPageButton 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
`ThumbnailPageButton.TOOLTIP_SELECTED`	Tooltip for selected button state
`ThumbnailPageButton.TOOLTIP_UNSELECTED`	Tooltip for unselected button state

Example Code
This example demonstrates how to use the ThumbnailPageButton component in a simple viewer. In this example a Container object,
a PageView object, a ThumbnailGridView object, a ControlBar object, a ScrubberSwatchesButton object, a ThumbnailPageButton
object, a PageScrubber object, and a Swatches object are created. When a user clicks the ScrubberSwatchesButton, the PageScrubber
and Swatches objects toggle visibility on or off to match the button selection state. When a user clicks the ThumbnailPageButton,
the ThumbnailGridView object visibility toggles on or off to match the button selection state. When a user interacts with the
PageView object, the ThumbnailGridView object, the PageScrubber object, or the Swatches object, the PageView object loads and
displays the newly selected page(s). Note that the event handlers for all of these components all call the switchToPage() function
that updates all of the component objects at once whenever the currently selected page changes.

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.
