FlexContainer Properties

The properties for FlexContainer widget are as follows.

accessibilityConfig Property

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 Volt MX 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 Volt MX 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.

Key Type Description ARIA Equivalent
a11yIndex Integer with no floating or decimal number. This is an optional parameter. Specifies the order in which the widgets are focused on a screen. For all widgets, this parameter maps to the aria-index, index, or taborder properties.
a11yLabel String This is an optional parameter. Specifies alternate text to identify the widget. Generally the label should be the text that is displayed on the screen. For all widgets, this parameter maps to the aria-labelledby property of ARIA in HTML. > Note: For the Image widget, this parameter maps to the alt attribute of ARIA in HTML.
a11yValue String This is an optional parameter. 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. This parameter is similar to the a11yLabel parameter. If the a11yValue is defined, the value of a11yValue is appended to the value of a11yLabel. These values are separated by a space.
a11yHint String This is an optional parameter. 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. For all widgets, this parameter maps to the aria-describedby property of ARIA in HTML.
a11yHidden Boolean This is an optional parameter. 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 For all widgets, this parameter maps to the aria-hidden property of ARIA in HTML.
a11yARIA Object This is an optional parameter. For each widget, the key and value provided in this object are added as the attribute and value of the HTML tags respectively. Any values provided for attributes such as aria-labelledby and aria-describedby using this attribute, takes precedence over values given in a11yLabel and a11yHint fields. When a widget is provided with the following key value pair or attribute using the a11yARIA object, the tabIndex of the widget is automatically appended as zero.{"role": "main"}``aria-label This parameter is only available on the Desktop Web platform.

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\")"
};

Platform Availability

activeStateSkin Property

Specifies the look and feel of a widget when the widget is in focus.

When the activeStateSkin property is configured for a widget, the activeStateSkin is applied to the widget when a user focuses on the widget (either by using the TAB key, mouse-click, or by using the setActive API programmatically).

Syntax


activeStateSkin

Type

String

Remarks

If a widget has the activeStateSkin, focusSkin, and the hoverSkin properties configured, the skins are applied based on the mouse-action performed on the widget:

  • The focusSkin is applied on the mouse-down action on the widget.
  • The hoverSkin is applied on the mouse-over action on the widget.
  • The activeStateSkin is applied on the mouse-release action on the widget.

Example

Setting the activeStateSkin property on an existing widget

//The Active State Skin is a skin created under the Skins tabfrmButton.myButton.activeStateSkin= 'btnActiveStateSkin';

a11yNavigationMode

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

anchorPoint 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

autogrowMode 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:

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

Syntax


autogrowMode

Type

Number

Read/Write

Read only

Remarks

Note: If you want to configure this property in Volt MX Iris, configure the height property of FlexContainer as preferred, then Volt MX Iris generates the autogrowMode property as voltmx.flex.AUTOGROW_HEIGHT.

The default value for this property is voltmx.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 voltmx.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 voltmx.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 voltmx.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 Volt MX Iris generates the autogrowMode property as voltmx.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=voltmx.flex.AUTOGROW_NONE;

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

backgroundColor Property

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.

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";

Platform Availability

  • Android
  • iOS
  • Desktop Web (Not available on Desktop Web Legacy SDK)

backgroundColorMultiStepGradient Property

Specifies the multi-step gradient color for the background of the widget.

Syntax

    • angle [Number]: Specifies the angle for the gradient in degrees, counted counter-clockwise. This property is only applicable for the custom gradient type.
    • colors [Array]: Specifies the colors for the multi-step gradient. Colors is an array of color hex values that indicate the reference color values of the gradient. This parameter contains an array of hexadecimal numbers that represent the colors or constants defined at the theme level.
    • colorStops [Array]: Specifies the color stops for the multi-step gradient. Color Stops 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). This parameter contains an array of numbers that represent the color stops.

Remarks

  • The default value of the gradientType key is voltmx.skin.MULTI_STEP_GRADIENT_TYPE_TO_TOP.
  • Colors can be specified using a 6 digit or an 8-digit hex value with alpha position. For example, ffff65 or ffffff00.

blur 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
};

isMaster Property

Specifies whether the container is a master container.

Syntax


isMaster

Type

Boolean

Read/Write

Read Only after initialization.

Remarks

If the isMaster property is true, the current widget is a master container and all of the rules and limitations of master containers apply to it. For more information, please see Masters in the Overviews section of this guide, as well as Using Masters in the Iris User Guide.

Your app can set the isMaster property in this container's constructor. After that, this property is read-only.

Example


var isMasterContainer = flexContainer1.isMaster;

isModalContainer Property

When you use the FlexContainer as a popup, this property helps to prevent user interaction beyond the edges of the FlexContainer.

Syntax


isModalContainer

Type

Boolean

Remarks

The default value for this property is voltmx.flex.FREE_FORM.

Note: This property can only be set during widget construction.

The available options are:

  • voltmx.flex.FREE_FORM: The calculations for free form layout type are:
    • left is measured from the left bounds of the parent, right is measured from the right bounds of the parent and centerX measured from the left bounds of the parent.
    • top is measured from the top bounds of the parent, bottom is measured from the bottom bounds of the parent and centerY measured from the bop bounds of the parent.
    • For x-axis values are width, left, right, centerX in case of % units are relative to parent's width.
    • For y-axis values are height, top, bottom, centerY in case of % units are relative to parent's height.
  • voltmx.flex.FLOW_HORIZONTAL: The calculations for horizontal layout type are:
    • left is measured from right edge of the left sibling widget and right is measured from the left edge of the right sibling widget.
    • horizontal space between two widgets is right of the left sibling widget + left of the right sibling widget.
    • order of the widgets appearing in the flow is the order in which the widgets are added.
    • top and bottom properties are measured from the boundaries of the parent.

  • voltmx.flex.FLOW_VERTICAL: The calculations for vertical layout type are:

    • top is measured from bottom edge of the top sibling widget and bottom is measured from the top edge of bottom sibling widget.
    • vertical space between two widgets is bottom of the top sibling widget + top of the bottom sibling widget.
    • order of the widgets appearing in the flow is the order in which the widgets are added.
    • left and right properties are measured from the boundaries of the parent.
    • voltmx.flex.RESPONSIVE_GRID: When you assign the value of the layoutType property as voltmx.flex.RESPONSIVE_GRID, you can assign different layouts for different breakpoints. Here are the some of the things to consider when you assign the Responsive Grid layout.
    • Widgets are aligned from left to right with the span and offset values provided in the Look tab of the Properties panel.
    • You can only provide FlexContainer widget as the direct child after assigning this value to the parent.
    • The FlexContainer cell respects height, minHeight, maxHeight property only.
    • If the width of a child widget exceeds the width of the container widget, the next child widget is wrapped and placed in the next row.

Type

String

Read/Write

Read + Write

Input Parameters

Parameter NameTypeDefault ValueDescription
translateBooleantrueThis 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.
XboundariesArraySize of the current widgetThis is an optional parameter and it defines the boundaries of the swipe in the X-axis.
swipeLeft/swipeRightJS 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.
translateRangeArraySize of the current widgetThis is an optional parameter and it defines the sub-boundaries for the action when the swipe action ends.
translatePosArrayPrevious position of the widgetThis 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.
callbackJS ObjectnullThis 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 NameTypeDescription
widgetHandle This parameter consists of the widget handle or ID of the widget on which the swipe action has been performed.
contextJS ObjectThis is applicable only for widgets inside the Segment with row templates. Each context parameter consists of rowIndex, sectionIndex and widgetref
rowIndexNumberThis parameter stores the row index of the Segment containing the swiped widget.
sectionIndexNumberThis parameter stores the section index of the Segment containing the swiped widget.
widgetrefwidgetHandleThis 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.

//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.  
var swipeMoveConfig = {
 "translate": true,
 "Xboundaries": ["-60%", "60%"],
 "swipeLeft": [{
  "translateRange": ["-60%", "0%"],
  "callback": null,
  "translatePos": "-60%",

width Property

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


width

Type

Number, String, and Constant

Read/Write

Read + Write

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.
  • voltmx.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";

Platform Availability

zIndex 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 Volt MX 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 Volt MX 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;
