FlexContainer Properties

The properties for FlexContainer widget are as follows.

ClosedaccessibilityConfig Property

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"    
};

Platform Availability

  • Available in the IDE
  • iOS, Android, SPA, and Desktop Web
Closeda11yNavigationMode

The property helps to specify the type of navigation order that should be used in the FlexContainer.

Syntax

a11yNavigationMode

Type

Number

Read/Write

Read + Write

Remarks

You can define any one of the following values to the property:

  • constants.ACCESSIBILITY_NAVIGATION_MODE_NATIVE: Native accessibility navigation. Applies the platform's default accessibility navigation order. This is the default value for the property.
  • constants.ACCESSIBILITY_NAVIGATION_MODE_PARENT: Applies a custom navigation for widgets based on the a11yIndices set to the child widgets.
  • constants.ACCESSIBILITY_NAVIGATION_MODE_DEFAULT: Derives the property value from its immediate parent going all the way to form level.

Example

//Sample code to set the a11yNavigationMode property to a FlexContainer widget.

myForm.myFlexContainer.accessibilityConfig = {
    "a11yNavigationMode": constants.ACCESSIBILITY_NAVIGATION_PARENT   
};

Availability

iOS

ClosedanchorPoint Property

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
ClosedautogrowMode Property (Deprecated)

This property is enables you to grow the height of the FlexContainer when child widgets or content is added on the FlexContainer. The options are:

The autogrowMode property is used to set the height of a widget dynamically based on the derived height of the widget’s content, or from the child widget’s contents. The options are:

  • kony.flex.AUTOGROW_NONE (value is 0)
  • kony.flex.AUTOGROW_HEIGHT (value is 1)

Syntax

autogrowMode

Type

Number

Read/Write

Read only

Remarks

Note: If you want to configure this property in Kony Visualizer, configure the height property of FlexContainer as preferred, then Kony Visualizer generates the autogrowMode property as kony.flex.AUTOGROW_HEIGHT.

The default value for this property is kony.flex.AUTOGROW_NONE.

Note: If one or all the child widgets height or other properties such as centerY, top, bottom, minHeight or maxHeight are used in determining the height given in percentage (%), then the autogrowMode property will not work for the FlexContainer and its height fallback to default configuration value.

Rules and priorities of autogrowMode property

  • The autogrowMode property is ignored if the height of the widget is computable either through explicit value or implicit calculation.

  • If the autogrowMode property is configured as kony.flex.AUTOGROW_HEIGHT, then preferredSize (based on content or child widgets ) is computed, and min/max constraints are applied.
  • If the autogrowMode property is configured as kony.flex.AUTOGROW_NONE, the default value is applied with min/max constraints.
  • The height of a FlexContainer widget will not grow dynamically if the height of any widget changes because of the change in widget's skin state (such as from normal to focus).
  • If a widgets top value is given in negative values, then the widget is clipped in case of Free Form and overlapped on the previous widget in case of Flow Vertical.
  • The autogrowMode property is not supported for a FlexContainer widget that is placed inside an HBox or a VBox.
  • For example, a FlexContainer (flexA) has a FlexContainer (flexB), which is not set to grow dynamically, whose clipBounds is set to false. The children of flexB that are out of the bounds of flexB do not have any effect on the height of flexA. Only the heights of direct children of flexA will decide the height of flexA.
  • In templates, FlexContainer will grow only in SegmentedUI Table View only. In all other views, autogrowMode property is not supported.
  • The autogrowMode property for a FlexContainer is not supported in the Tab Widget.
  • In the Windows platform, the autogrowMode property of a SegmentedUI is not supported inside a FlexContainer.
  • The autogrowMode property of a SegmentedUI with a large number of rows leads to performance and memory issues.
  • Excessive usage of auto grow flex containers inside a form will impact the performance of the application.
  • Rendering of widgets with preferred height or preferred width will take more time in mobile and tablet browsers compared to desktop browsers.
  • When animating the height property of the child widget of a FlexContainer in iOS, Windows, and SPA platforms, after the animation is complete, then parent containers height increases based on the value provided in 100th step when fillMode is configured as kony.anim.FILL_MODE_FORWARDS.
  • When animating the height property of the child widget of a FlexContainer in the Android platform, the parent container's height grows along with the child widget's height.

When to Use

Case1: If the height of the FlexContainer is dependent on the heights of the child widgets that are added.

Case2: If you are using the FlexContainer in a SegmentedUI template, where each row of the SegmentedUI row height is dependent on the child widgets content. Configure the height property of the FlexContainer as preferred, then Kony Visualizer generates the autogrowMode property as kony.flex.AUTOGROW_HEIGHT.

Example

//Sample code to set the autogrowMode property of a FlexContainer widget.
//Here, flexcontainer1 FlexContainer retains the height given in the height Property.
frmHome.flexcontainer1.autogrowMode=kony.flex.AUTOGROW_NONE;

//Here, flexcontainer1 FlexContainer uses the child widget content to determine its height.
frmHome.flexcontainer1.autogrowMode=kony.flex.AUTOGROW_HEIGHT;

Platform Availability

ClosedbackgroundColor Property

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]
};

Platform Availability

  • iOS, Android, Windows, and SPA
Closedblur 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

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
};

Syntax

frame

Type

JSObject

Read/Write

Read only

Remarks

The frame values are correct when you app is processing the doLayout event. Accessing the frame property in the postShow event handler is not suggested as the layout cycles are still being calculated and the frame values might not be up to date.

Example

Getting the frame property on an existing widget


//Getting the derived width of an existing widget
var flexcontainerWidth = frmHome.flexcontainer1.frame.width;

//Getting the derived height of an existing widget
var flexcontainerWidth = frmHome.flexcontainer1.frame.height;

//Getting the derived left position of an existing widget
var flexcontainerLeft = frmHome.flexcontainer1.frame.x;

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.

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";

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

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;
