Object
Read/Write
Read + Write
Remarks
- The accessibilityConfig property is enabled for all the widgets which are supported under the Flex Layout.
Note: From VoltMX 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 ina11yLabel
,a11yValue
, anda11yHint
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, thetabIndex
attribute is added automatically to theaccessibilityConfig
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.
Example 2
This example uses the button widget to implement internationalization in accessibilityConfig
property, but the principle remains the same for all widgets.

anchorPoint Property
Specifies the anchor point of the widget bounds rectangle using the widget’s coordinate space.
Syntax
Type
JSObject
Read/Write
Read + Write
Remarks
The value for this property is a JavaScript dictionary object with the keys “x” and “y”. The values for the “x” and “y” keys are floating-point numbers ranging from 0 to 1. All geometric manipulations to the widget occur about the specified point. For example, applying a rotation transform to a widget with the default anchor point causes the widget to rotate around its center.
The default value for this property is center ( {“x”:0.5, “y”:0.5} ), that represents the center of the widgets bounds rectangle. The behavior is undefined if the values are outside the range zero (0) to one (1).
Example
Platform Availability
- iOS, Android, Windows, and SPA
backgroundColor Property
Specifies the background color of the widget.
Syntax
Type
Color constant or Hexadecimal number
Read/Write
Read + Write
Remarks
- The initial value of backgroundColor has to be specified explicitly. If not, Iris will not deduce the values from the existing skin and this will lead to undefined behavior.
- Colors can be specified using a 6 digit or an 8-digit hex value with alpha position. For example, ffff65 or ffffff00.
- When the 4-byte color format (RGBA) string is used, an alpha (A) value of 65 specifies that the color is transparent. If the value is 00, the color is opaque. The Alpha value is in percentage and must be given in the hexadecimal value for the color (100% in hexadecimal value is 65).
For example, red complete opaque is FF000000. Red complete transparent is FF000065. The values 0x and # are not allowed in the string. - A color constant is a String that is defined at the theme level. Ensure that you append the $ symbol at the beginning of the color constant.
- This property does not have a default value.
- This property has more priority than (and overrides) the background property of the configured skin. Even if there is no skin configured for the widget, this property updates the skin.
- The backgroundColor, backgroundColorTwoStepGradient, backgroundColoMultiStepGradient, and backgroundImage properties are mutually exclusive. The property that was set most recently is given higher priority over other properties.
Example
This example uses the button widget, but the principle remains the same for all widgets that have the backgroundColor property.

blur Property
You can enable or disable a blur-effect for a widget(for example, a FlexContainer) by making use of a constructor-level property, called blur. The blur property accepts a dictionary that contains the following keys: enabled, value and style. You must specify an appropriate value for the dictionary keys, otherwise the property will not be valid.
Syntax
Input Parameters
- enabled: Accepts a Boolean value that basically decides whether to enable or disable the blur-effect for the widget. This is a mandatory attribute.
-
value: Level of the blur-effect that needs to be set for the widget. It should ideally be between 0 to 100. If the level is set as 0 no blur is set, even when the enabled property is set as true. This is a mandatory attribute. Even when the enabled attribute is set as false, you need to specify a numerical value to this attribute.
- style: Specifies the style in which the blur property can be applied to a widget. This is an optional parameter specific to iOS. The default value of this parameter is constants.BLUR_EFFECT_LIGHT. You can specify any of the following values to this parameter:
- constants.BLUR_EFFECT_NONE
-
constants.BLUR_EFFECT_EXTRALIGHT
- constants.BLUR_EFFECT_LIGHT (default)
-
constants.BLUR_EFFECT_DARK
-
constants.BLUR_EFFECT_REGULAR
- constants.BLUR_EFFECT_PROMINENT
Read/Write
Read + Write
Remarks
- If you set enabled as true, the blur-effect for the widget is enabled.
- If you set enabled as false, the blur-effect for the widget is disabled.
-
If you specify value as less than 0, the value is taken as 0.
- If you specify value as greater than 100, the value is taken as 100.
Limitations
- For Android:
-
If a FlexContainer or a FlexScrollContainer contains a Map widget, the blur-effect is not applied to the map.
-
If a FlexContainer or a FlexScrollContainer contains a Browser or Video widget, the blur-effect is applied but does not get updated. For example, when the video starts playing, the new rendered frame does not get displayed with the blur-effect.
- Even if you apply 100% blur for widgets that display any text( such as Label or Calendar widgets), the text on these widgets is not blurred. This is a Native Android limitation. To generate the blur effect for the text, apply a skin with darker background to the Label or Calendar widget. This is true even when the widgets are placed in a FlexContainer with blur effect and the widgets do not have a skin.
- Blur effect will not work on widgets added inside BOX containers.
-
Example 1
To dynamically set the blur-effect for any widget, such as a FlexContainer, use the following code.
Example 2
To dynamically set the blur-effect for any widget, such as a FlexContainer in iOS, use the following code.

Type
String
Read/Write

Input Parameters
Parameter Name | Type | Default Value | Description |
translate | Boolean | true | This is an optional parameter. When the value of this parameter is set as true, the widget moves along with the swipe in the same direction. |
Xboundaries | Array | Size of the current widget | This is an optional parameter and it defines the boundaries of the swipe in the X-axis. |
swipeLeft/swipeRight | JS Object | This is an optional parameter and it is used to define the configuration of the widget while swiping to the left/ right. Each swipeLeft or swipeRightparameter is an array of configuration attributes containing translateRange , callback , translatePos , and translate. This JS Object defines the behavior of the widget during the swipe action. | |
translateRange | Array | Size of the current widget | This is an optional parameter and it defines the sub-boundaries for the action when the swipe action ends. |
translatePos | Array | Previous position of the widget | This is an optional parameter and it determines the final translation position to be applied to the widget when the widget swipe reaches the translateRange value. |
callback | JS Object | null | This is an optional parameter and it defines the callback which needs to be triggered when the finger swipe reaches the sub boundary defined in translateRange. The attributes inside this parameter are described in the following table. |
The following table consists of the parameters of the callback parameter:
Parameter Name | Type | Description |
widgetHandle | This parameter consists of the widget handle or ID of the widget on which the swipe action has been performed. | |
context | JS Object | This is applicable only for widgets inside the Segment with row templates. Each context parameter consists of rowIndex, sectionIndex and widgetref |
rowIndex | Number | This parameter stores the row index of the Segment containing the swiped widget. |
sectionIndex | Number | This parameter stores the section index of the Segment containing the swiped widget. |
widgetref | widgetHandle | This parameter stores the handle of the Segment containing the swiped widget. |
Remarks
- For a Segment, the widgetSwipeMove Property is configured while setting the data of the Segment.
Note: It is not recommended to assign the widgetSwipeMove property on a top Flex container of the segment template widget.
Limitations
- When a translation animation is applied to the same widget that has widgetSwipeMove already configured, the action which has been performed last takes precedence. For example, if you have set a translation animation on a FlexContainer and then set the widgetSwipeMove property, the actions set in widgetSwipeMove take precedence over the translation animation.
- The state of the swipe transition of the widget is not retained.
-
In a Segment, the widgetSwipeMove Property must be configured for the rows so that they reset to the previous position.
- If the widgetSwipeMove property is configured on a top level Flex container of a segment template, the onRowClick event will not be triggered. - Applicable on iOS, Android, and SPA.
- Android limitation: On Android devices, when the user lifts their finger, the transition occurs immediately.
Example
Following is a code snippet for a mail app. Here we have used a Segment for listing the mail and the widgetSwipeMove Property has been configured for the SwipeFlex FlexContainer.
Platform Availability
- Android, iOS, and SPA
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 VoltMX Iris hierarchy, inside of a flexContainer or form. The zIndex property accepts only positive values.
Syntax
Type
Number
Read/Write
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 VoltMX 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.
