FlexScrollContainer 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
};

Specifies the background color of the widget in hex format. The background can be a single color or a gradient of several colors.

Syntax

backgroundColor

Type

String

Read/Write

Read + Write

Remarks

This property does not have default value.

This property has more priority compared to the values coming from the configured skin.

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.

The value can specify either a solid color, or a gradient:

Solid color:

Solid colors can be specified using a 6 digit or an 8 digit hex value with alpha position. For example, ffffff or ffffff00.

When the 4-byte color format (RGBA) string is used, an alpha (A) value of FF specifies that the color is transparent. If the value is 00, the color is opaque. For example, red complete opaque is FF000000. Red complete transparent is FF0000FF. The values 0x and # are not allowed in the string.

Gradient:

A gradient is specified as follows:

Form1.widgetID.backgroundColor = {
    "angle": 45,
    "colors": ["ea5075", "f1fa70", "eefd04"],
    "colorStops": [0, 90, 100]
};

Where:

• angle is the angle of the gradient in degrees, counted counter-clockwise.
• colors is an array of color hex values that indicate the reference color values of the gradient.
• colorStops are the locations of the reference colors on the gradient, from 0 (the start of the gradient) to 100 (the final value of the gradient).

Example

Form1.lbl1.backgroundColor = {
    "angle": 45,
    "colors": ["ea5075", "f1fa70", "eefd04"],
    "colorStops": [0, 90, 100]
};

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
};

• 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.

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.
