Class s7sdk.common.CloseButton

The CloseButton is used to close the viewer's browser window when the window is opened using JavaScript.

This component does not currently read any modifiers.

Defining the Appearance using CSS

The CSS class for styling the CloseButton is .s7closebutton. This button has four states: up, over, down and disabled. You can style these states by adding the state attribute selector to the CSS class. It is recommended that you define common CSS under the main class and only define the necessary distinctions when using attribute selectors.

CSS Class	Attribute Selector	Description
`.s7closebutton`	`state=[up\|over\|down\|disabled]`	Define the appearance of `CloseButton` for the various states.
`.s7tooltip`	(None)	A global class selector that defines appearance for the tooltips. To disable tooltips set the `display` style to `none`.

Localized Symbols

CloseButton 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
`CloseButton.TOOLTIP`	Define a localized tooltip of `CloseButton`

Example Code
This example demonstrates how to use the CloseButton component in a simple viewer. In this example a Container object,
a ZoomView object, and a CloseButtonButton object are created. Clicking the close button closes the Web browser window 
which contains the viewer.

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 ZoomView and CloseButton 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.).
A handler function is defined to respond to the component event listener 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.
