Localization of user interface elements

Certain content that the Flyout Viewer displays is subject to localization. This content includes user interface element tool tips and information messages that are displayed by the flyout zoom view on load.

Every textual content in the viewer that can be localized is represented by a special Viewer SDK identifier called SYMBOL. Any SYMBOL has a default associated text value for the English locale ( "en") supplied with the out-of-the-box viewer. It may also have user-defined values set for as many locales as needed.

When the viewer starts, it checks the current locale to see if there is a user-defined value for each supported SYMBOL for the locale. If there is, it uses the user-defined value; otherwise, it falls back to the out-of-the-box default text.

User-defined localization data can be passed to the viewer as a localization JSON object. Such object contains the list of supported locales, SYMBOL text values for each locale, and the default locale.

An example of such a localization object is the following:

"FlyoutZoomView.TIP_BUBBLE_OVER":"Mouse over to zoom",
"FlyoutZoomView.TIP_BUBBLE_TAP":"Tap and hold to zoom"
"FlyoutZoomView.TIP_BUBBLE_OVER":"Passez la souris sur pour zoomer",
"FlyoutZoomView.TIP_BUBBLE_TAP":"Appuyez et maintenez pour agrandir"

In the above example, the localization object defines two locales ( "en" and "fr") and provides localization for two user interface elements in each locale.

The web page code should pass the localization object to the viewer constructor, as a value of the localizedTexts field of the configuration object. An alternative option is to pass the localization object by calling the setLocalizedTexts(localizationInfo) method.

The following SYMBOLs are supported:




ARIA label for top-level viewer element.


ARIA role description for main view component.


ARIA usage hints for keyboard users.


Information message for desktop systems.


Information message for touch devices.


Tooltip for scroll left button.


Tooltip for scroll right button.


Tooltip for scroll up button.


Tooltip for scroll down button.
