ListBox Properties

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 VoltMX 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 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 in a11yLabel, a11yValue, and a11yHint fields.

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

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\")"
};

Specifies the anchor point of the widget bounds rectangle using the widget’s coordinate space.

Syntax

anchorPoint

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

Form1.widget1.anchorPoint = {
    "x": 0.5,
    "y": 0.5
};

Remarks

The default value for the property is false.

• If set to true, the skin is applied to the popup.
• If set to false, the skin is not applied to the popup.

Specifies the background color of the widget.

Syntax

backgroundColor

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.

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

blur

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.

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

Form1.myFlexContainer.blur = {
    "enabled": true,
    "value": 60
};

Example 2

To dynamically set the blur-effect for any widget, such as a FlexContainer in iOS, use the following code.

Form1.widget1.blur = {
    "enabled": true,
    "value": 60,
    "style": constants.BLUR_EFFECT_DARK
};

Remarks

• 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 shadow property of the configured skin. Even if there is no skin configured for the widget, this property updates the skin.

• 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 textShadow property of the configured skin. Even if there is no skin configured for the widget, this property updates the skin.

For editview viewType

• Users can use this viewType to change the colour of a drop-down item on hover, which is not possible with the select attribute provided by.html for list. You can customize drop-down items to a great extent and use this to cater to the needs of users with respect to drop-down type widgets in a better manner. This is applicable only for Desktop Web.
• Assumptions:

  • The ListBox widget has to be dynamically created in order to use the editview viewType, which is defined as a platform-specific property (pspconfig) for this widget.

  • You can update masterData, selectedKey, editableAreaSkin, viewtType, and autoSuggest.

• Limitations:

  • The editview viewType is available only in Desktop Web.

  • The editview viewType supports only single select, so there is no option of selectedKeys.

Input Parameters

The following table consists of the parameters of the callback parameter:

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.

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

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

zIndex

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.

//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;
