Browser Properties

The properties for Browser widget are as follows:

accessibilityConfig Property

Enables you to control accessibility behavior and alternative text for the widget.

For more information on using accessibility features in your app, see the Accessibility appendix in the Volt MX IrisUser Guide.

Syntax

accessibilityConfig

Type

Object

Read/Write

Read + Write

Remarks

The accessibilityConfig property is enabled for all the widgets which are supported under the Flex Layout.

Note: From Volt MX Iris V9 SP2 GA version, you can provide i18n keys as values to all the attributes used inside the accessibilityConfig property. Values provided in the i18n keys take precedence over values provided in a11yLabel, a11yValue, and a11yHint fields.

The accessibilityConfig property is a JavaScript object which can contain the following key-value pairs.

Key	Type	Description	ARIA Equivalent
a11yIndex	Integer with no floating or decimal number.	This is an optional parameter. Specifies the order in which the widgets are focused on a screen.	For all widgets, this parameter maps to the `aria-index`, `index`, or `taborder` properties.
a11yLabel	String	This is an optional parameter. Specifies alternate text to identify the widget. Generally the label should be the text that is displayed on the screen.	For all widgets, this parameter maps to the `aria-labelledby` property of ARIA in HTML. > *Note:* For the Image widget, this parameter maps to the alt attribute of ARIA in HTML.
a11yValue	String	This is an optional parameter. Specifies the descriptive text that explains the action associated with the widget. On the Android platform, the text specified for a11yValue is prefixed to the a11yHint.	This parameter is similar to the a11yLabel parameter. If the a11yValue is defined, the value of a11yValue is appended to the value of a11yLabel. These values are separated by a space.
a11yHint	String	This is an optional parameter. Specifies the descriptive text that explains the action associated with the widget. On the Android platform, the text specified for a11yValue is prefixed to the a11yHint.	For all widgets, this parameter maps to the `aria-describedby` property of ARIA in HTML.
a11yHidden	Boolean	This is an optional parameter. Specifies if the widget should be ignored by assistive technology. The default option is set to false. This option is supported on iOS 5.0 and above, Android 4.1 and above, and SPA	For all widgets, this parameter maps to the `aria-hidden` property of ARIA in HTML.
a11yARIA	Object	This is an optional parameter. For each widget, the key and value provided in this object are added as the attribute and value of the HTML tags respectively. Any values provided for attributes such as `aria-labelledby` and `aria-describedby` using this attribute, takes precedence over values given in `a11yLabel` and `a11yHint` fields. When a widget is provided with the following key value pair or attribute using the a11yARIA object, the tabIndex of the widget is automatically appended as zero.{"role": "main"}``aria-label	This parameter is only available on the Desktop Web platform.

Android limitations

If the results of the concatenation of a11y fields result in an empty string, then accessibilityConfig is ignored and the text that is on widget is read out.
The soft keypad does not gain accessibility focus during the right/left swipe gesture when the keypad appears.

SPA/Desktop Web limitations

When accessibilityConfig property is configured for any widget, the tabIndex attribute is added automatically to the accessibilityConfig property.
The behavior of accessibility depends on the Web browser, Web browser version, Voice Over Assistant, and Voice Over Assistant version.
Currently SPA/Desktop web applications support only a few ARIA tags. To achieve more accessibility features, use the attribute a11yARIA. The corresponding tags will be added to the DOM as per these configurations.

Example 1

This example uses the button widget, but the principle remains the same for all widgets that have an accessibilityConfig property.


//This is a generic property that is applicable for various widgets.
//Here, we have shown how to use the accessibilityConfig Property for button widget.
/*You need to make a corresponding use of the accessibilityConfig property for other applicable widgets.*/

Form1.myButton.accessibilityConfig = {
    "a11yLabel": "Label",
    "a11yValue": "Value",
    "a11yHint": "Hint"    
};

Example 2

This example uses the button widget to implement internationalization in accessibilityConfig property, but the principle remains the same for all widgets.


/*Sample code to implement internationalization in accessibilityConfig property in Native platform.*/

Form1.myButton.accessibilityConfig = {
    "a11yLabel": voltmx.i18n.getLocalizedString("key1")     
};  
/*Sample code to implement internationalization in accessibilityConfig property in Desktop Web platform.*/

Form1.myButton.accessibilityConfig = {
    "a11yLabel": "voltmx.i18n.getLocalizedString(\"key3\")"
};

limitsNavigationsToAppBoundDomains Property

The iOS App-Bound Domains feature limits the tracking risk of in-app browsing, by restricting domain access by the app to those you specify. To use the feature, you add the WKAppBoundDomains key to <projectDirectory>/resources/common/infoplist_configuration.jsonand supply an array of domain name strings as the value. Here is a sample infoplist_configuration.json file entry to set app bound domains.

{ 
   "WKAppBoundDomains" : ["https://www.ExampleDomainl.com", "https://www.ExampleDomain2.com", "https://www.ExampleDomain3.com"]
}

By default, Browser widgets with Browser Type = WKWebView can use JavaScript injection, custom style sheets, cookie manipulation, and message handlers. However, once you add "WKAppBoundDomains" to infoplist_configuration.json, all WKWebView Browser instances in the app lose these capabilities. To restore access to these APIs, set limitsNavigationsToAppBoundDomains to true in the Browser widget configuration.

Note: You can also access the limitsNavigationsToAppBoundDomains property through code as part of the pspConfig Object. However, you can only enable (or add) this property when you create the Browser widget instance. You cannot change the value of this property after the Browser widget is initialized.

screenLevelWidget Property

Specifies whether the widget should occupy the whole container or not when your Browser widget has a large HTML content to display.

Syntax

screenLevelWidget

Type

Boolean

Read/Write

No

Remarks

The default value for this property is false.

You must set the value to true for your Browser widget occupy the complete Form and results in a good user experience.

If set to false, the widget does not occupy the whole container and a scroll bar appears on the Browser widget and the Form resulting in a bad user experience while scrolling.

You must not place more than one Browser widget as a screen level widget inside a Form. Also, if you choose to make a Browser widget a Screen Level Widget, you must place only the Browser widget in the Form and must not place any other widgets in the Form.

Do not set the screen level widget property to true for more than one widget in the form. If you have multiple widgets with this property set as true, there may be issues with how information is displayed along with some scrolling issues.

Few guidelines for using screenLevelWidget property for Browser widget.

Placing any widgets below the Browser widget on a form is not advised as this leads to double scrolling issues. Use Browser widget as screen level widget and place the rest of the widgets as part of headers and footers.
In order to control the height of the Browser widget, place browser widget as screen level widget inside the ScrollBox and control the height of the ScrollBox.

On iPhone, Android, and Windows 10 platforms, if this property is set to true, the following are applicable:

iPhone

When a browser widget is used on the form, make sure that all other widgets are part of header or footer of the form.

Android

Only the widgets placed above the Browser widget (which is a screen level widget) are visible. The widgets placed below the Browser widget are not visible when rendered.

Windows

The widgets placed above and below the Browser widget (which is a screen level widget) are not visible when rendered.

Note: If you configure Application level Header and Footer, they will be visible even if the browser is a screen level widget.

The width property determines the width of the widget’s bounding box. The value may be set using DP (Device Independent Pixels), Percentage, or Pixels. For supported widgets, the width may be derived from either the widget or container’s contents by setting the width to “preferred”.

Syntax

width

Type

Number, String, and Constant

Read/Write

Read + Write

Remarks

Following are the options that can be used as units of width:

%: Specifies the values in percentage relative to the parent dimensions.
px: Specifies the values in terms of device hardware pixels.
dp: Specifies the values in terms of device independent pixels.
default: Specifies the default value of the widget.
voltmx.flex.USE_PREFERED_SIZE: When this option is specified, the layout uses preferred width of the widget as width and preferred size of the widget is determined by the widget and may varies between platforms.

Example


//Sample code to set the width property for widgets by using DP, Percentage and Pixels.
frmHome.widgetID.width = "50dp";

frmHome.widgetID.width = "10%";

frmHome.widgetID.width = "10px";

zIndex Property

This property specifies the stack order of a widget. A widget with a higher zIndex is always in front of a widget with a lower zIndex.

The zIndex property is used to set the stack, or layer order of a widget. Widgets with higher values will appear “over”, or “on top of” widgets with lower values. Widgets layered over other widgets will override any interaction events tied to widgets beneath. Modifying the zIndex does not modify the order of the widgets in the Volt MX Iris hierarchy, inside of a flexContainer or form. The zIndex property accepts only positive values.

Syntax

Type

Number

Read/Write

Remarks

The default value for this property is 1.

Note: Modifying the zIndex does not modify the order of the widgets inside the FlexContainer. If zIndex is same for group of overlapping widgets then widget order decides the order of overlapping. The last added widget is displayed on top.

From Volt MX Iris V9 SP2 FP7, developers can configure the Z Index value for a Responsive Web app as Auto or Custom. When the selected Z Index value is Auto, the default Z Index value of 1 is applied. When the selected Z Index value is Custom, developers can specify a desired numeric value.

Prior to the V9 SP2 FP7 release, the default value for the Z Index was 1. When developers imported any third-party libraries with the Z index set as Auto, content overflow was disabled as the value of Auto is less than 1.

Note: The Z Index value Auto is supported only when the Enable JS Library mode is configured as unchecked.

For existing components, the value of the Z Index is configured as 1 for the Native channel. For the Responsive Web channel, the Z Index will be set as Custom with 1 as the value.

For new components, the value of the Z Index is configured as 1 for the Native channel. For the Responsive Web channel, the Z Index will be set as Auto or 1 based on the project level settings.

Note: If ModalContainer property is set to true in any of the FlexContainer widget, the Z Index value of that container and all of its parent containers should be set to Custom.

voltmx.flex.ZINDEX_AUTO : Constant to configure the Z Index value as auto programmatically.


//Sample code to set the ZIndex value to Auto  
 var flx = new voltmx.ui.FlexContainer({ 
  "id": "flx"
  "zIndex": voltmx.flex.ZINDEX_AUTO
});


//Sample code to set the ZIndex value to Auto
flx.zIndex = voltmx.flex.ZINDEX\_AUTO;

Example


//Sample code to set the zIndex property for widgets.  
frmHome.widgetID.zIndex = 300;
