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 Accessibility appendix.

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.

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

a11yLabel [String]

Optional. Specifies alternate text to identify the widget. Generally the label should be the text that is displayed on the screen.

a11yValue [String]

Optional. Specifies the current state/value associated with the widget so that the user can perform an action. For example, a checkbox is in selected state or unselected state. On the Android platform, the text specified for a11yLabel is prefixed to the a11yValue.

a11yHint [String]

Optional. 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.

a11yHidden [Boolean]

Optional. 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

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

• 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

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"    
};

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
};

Platform Availability

• iOS, Android, Windows, and SPA

This property determines the bottom edge of the widget and is measured from the bottom bounds of the parent container.

The bottom property determines the position of the bottom edge of the widget’s bounding box. The value may be set using DP (Device Independent Pixels), Percentage, or Pixels. In freeform layout, the distance is measured from the bottom edge of the parent container. In flow-vertical layout, the value is ignored. In flow-horizontal layout, the value is ignored.

The bottom property is used only if the Height property is not provided.

Remarks

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.

When the viewType is PICKER_VIEW_TYPE_FLAT:

This property is used to enable and configure left or right swipe actions for a widget. The widgetSwipeMove Property can be used for all widgets . The most common use case is for implementing swipe action for individual rows in Segment.

Syntax

widgetSwipeMove

Type

String

Read/Write

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, 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.*/
//Example of a swipe move configuration.

This property determines the width of the widget and is measured along the x-axis.

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

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.
• 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.
frmHome.widgetID.width = "50dp";

frmHome.widgetID.width = "10%";

frmHome.widgetID.width = "10px";

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 Kony hierarchy, inside of a flexContainer or form. zIndex accepts both negative and positive values.

Syntax

zIndex

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.

Example

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