PickerView Properties

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

For more information on using accessibility features in your app, refer the Accessibility appendix in the Quantum Application Design Guidelines Guide.

Syntax

accessibilityConfig

Type

JSON Object

Read/Write

Read + Write

Remarks

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

NOTE: From Quantum Visualizer 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.

Accessibility in Components

• In a FlexForm containing direct widgets and components, while providing values to the aria-labelledby and the aria-describedby properties for widgets directly inside the FlexForm, you must not provide the Id of the widgets inside the components.
• In a component containing direct widgets and child components, while providing values to the aria-labelledby and the aria-describedby properties for widgets directly inside the component, you must not provide the Id of the widgets inside the child components.

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.
• The i18n key support in accessibilityConfig property depends on the languages supported by the TTS(Text-To-Speech) engine of the mobile device. If the TTS engine of the mobile device does not support a language, the text provided in the accessibilityConfig property is not read by the TTS engine.

Accessibility in Desktop Web Platform

• To use the accessibilityConfig property on the Desktop Web platform, ensure that you disable the Legacy JS Mode in the Project Settings > Responsive Web section.
• 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 Desktop web applications support only a few ARIA tags. To achieve more accessibility features, use the attribute a11yARIA. The tags added to a11yARIA will be added to the DOM.

• The tagName attribute supports the following tags in the Label Segment, FlexContainer, and FlexScrollContainer widgets:

  Widget Name	Supported tags	Example	Remarks
  Label	label(default) div span h1, h2, h3, h4, h5, h6	The following example shows how to assign the tags to the Label widget. /*Sample code to assign the span tag to the Label widget*/ "accessibilityConfig": { "tagName": "span" }
  Segment	ul(default) ol div table dl	The following example uses the role and tagName attributes to modify the HTML tag of Segment widget. /*Sample code to assign the div tag to the Segment widget*/ "accessibilityConfig": { "a11yARIA": { "role": "grid" }, "tagName": "div" }	You can assign values to the role attribute inside the a11yARIA only when you modify the tag to div. You can only assign the following values to the role attribute of a Segment widget: grid table and button.
  FlexContainer	div (default) th td tr dt dd	The following example uses the role and tagName attributes to modify the HTML tag of a FlexContainer widget. /*Sample code to assign the td tag to a FlexContainer widget*/ var flx = new kony.ui.FlexContainer({ "accessibilityConfig": { "tagName": "td" } });	This is a read-only property. When you specify the value as tr for the tagName property of a FlexContainer widget, ensure that you use the Flex Horizontal Layout Type. The height of the FlexContainer widget is inherited from the height of the child widgets present inside it.
  FlexScrollContainer	div (default) th td dt dd	The following example uses the role and tagName attributes to modify the HTML tag of a FlexScrollContainer widget. /*Sample code to assign the td tag to a FlexScrollContainer widget*/ var flx = new kony.ui.FlexScrollContainer({ "accessibilityConfig": { "tagName": "td" } });	This is a read-only property.

Example 1

This example uses the Login scenario to explain how to provide accessibility to the usernameText TextBox widget inside the frmLogin Form. The frmLogin form also contains the usernameLbl Label widget (with the text Username) and rulesLbl Label widget(that contains the username policies).

//This is a generic property that is applicable for various widgets.
/*Here, we have shown how to use the accessibilityConfig Property for a TextBox widget.You need to make a corresponding use of the accessibilityConfig property for other applicable widgets.*/
frmLogin.usernameText.accessibilityConfig = {
  "a11yLabel": "Label",
  "a11yValue": "Value",
  "a11yHint": "Hint",
  "a11yARIA": {
    "tabindex" /* Integer with no floating/decimal numbers*/: 1,
    "role" /*Prescribed string value as per wcag guidelines*/: "main",
    "aria-labelledby": "usernameLbl"
    "aria-describedby": "rulesLbl"
  }
};

Example 2

This example creates a Label widget (lblSpan) inside the frmSample FlexForm. This sample code uses the tagName property to change the HTML tag of the lblSpan Label from label tag to span tag.

/*Here, we have shown how to use the accessibilityConfig Property for a Label widget. You need to make a corresponding use of the accessibilityConfig property for in Segment widget as well.*/
var lblspan = new kony.ui.Label({
  "accessibilityConfig": {
    "tagName": "span"
  },
  "id": "lblspan",
  "isVisible": true,
  "left": "460dp",
  "skin": "CopyslLabel0b3521e51e03b44",
  "text": "span tag",
  "top": "92dp",
  "width": kony.flex.USE_PREFFERED_SIZE,
  "zIndex": 1
}, {
  "contentAlignment": constants.CONTENT_ALIGN_MIDDLE_LEFT,
  "padding": [0, 0, 0, 0],
  "paddingInPixel": false
}, {});

frmSample.add(lblspan);

Example 3

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": kony.i18n.getLocalizedString("key1")     
};
/*Sample code to implement internationalization in accessibilityConfig property in Desktop Web platform.*/

Form1.myButton.accessibilityConfig = {
    "a11yLabel": "kony.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
};

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, Visualizer 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.

Form1.btn1.backgroundColor = "ea5075";

This property is used to retain flex positional property values as they were defined. The flex positional properties are left, right, and padding.

NOTE: Locale-level configurations take priority when invalid values are given to this property, or if it is not defined.

The mirroring widget layout properties should be defined as follows.

function getIsFlexPositionalShouldMirror(widgetRetainFlexPositionPropertiesValue) {
    return (isI18nLayoutConfigEnabled &&
    localeLayoutConfig[defaultLocale]
    ["mirrorFlexPositionalProperties"] == true &&

The changes made to the viewType property will not be reflected in the Visualizer canvas. But the changes will be reflected in the output.

The view of the PickerView widget in Android platform was same as the PickerWheel widget of the native iOS platform. From version 7.0 onwards, a new view of the PickerView is introduced for Android.

If a project containing PickerView is created in 7.0 version, the default value for the viewType property is PICKER_VIEW_TYPE_FLAT. In case the projects created using versions prior to 7.0, the default value of the viewType property is PICKER_VIEW_TYPE_WHEEL to support the backward compatibility.

In other words, PICKER_VIEW_TYPE_WHEEL is the default look and feel of the PickerView widget in versions prior to 7.0. From Visualizer 7.0 onwards, the default look and feel is PICKER_VIEW_TYPE_FLAT. In either case, you can change the value of viewType property if required.

widgetSwipeMove

Type

String

Read/Write

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 and Android.
• 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.

• 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.
• kony.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.

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 Quantum Visualizer 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 Quantum Visualizer 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.

kony.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 kony.ui.FlexContainer({ 
  "id": "flx"
  "zIndex": kony.flex.ZINDEX_AUTO
});

//Sample code to set the ZIndex value to Auto
flx.zIndex = kony.flex.ZINDEX_AUTO;
