Video Properties

The basic properties of Video widget are:

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\")"
};

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
};

retainFlowHorizontalAlignment Property

This property is used to convert Flow Horizontal Left to Flow Horizontal Right.

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 &&
    !widgetRetainFlexPositionPropertiesValue);
}

The following table illustrates how widgets consider Local flag and Widget flag values.

Properties	Local Flag Value	Widget Flag Value	Action
Mirror/retain FlexPositionProperties	true	true	Use the designed layout from widget for all locales. Widget layout overrides everything else.
Mirror/retain FlexPositionProperties	true	false	Use Mirror FlexPositionProperties since locale-level Mirror is true.
Mirror/retain FlexPositionProperties	true	not specified	Use Mirror FlexPositionProperties since locale-level Mirror is true.
Mirror/retain FlexPositionProperties	false	true	Use the designed layout from widget for all locales. Widget layout overrides everything else.
Mirror/retain FlexPositionProperties	false	false	Use the Design/Model-specific default layout.
Mirror/retain FlexPositionProperties	false	not specified	Use the Design/Model-specific default layout.
Mirror/retain FlexPositionProperties	not specified	true	Use the designed layout from widget for all locales. Widget layout overrides everything else.
Mirror/retain FlexPositionProperties	not specified	false	Use the Design/Model-specific default layout.
Mirror/retain FlexPositionProperties	not specified	not specified	Use the Design/Model-specific default layout.

right Property

This property determines the lower right corner of the widget and is measured from the right bounds of the parent container.

The right property determines the position of the right 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 left edge of the parent container. In flow-vertical layout, value is ignored. In flow-horizontal layout, the value is ignored.

The right property is used only if the width property is not provided.

source Property

The feature specifies the URLs of a video that is to be streamed, the path of the video from the local asset, and the video captured from the camera.

Note: It is mandatory to specify the URLs for all the three different formats. The device browser plays a format that is compatible with the underlying Native SDK.

Syntax


source

Type

JSObject

Read/Write

Yes - (Read and Write)

Remarks

Define the source parameter as a JSObject with key as mp4, mov, or rawBytes. For example:

SPA

{
    mp4: "mp4 URL",
    webm: "webm URL",
    ogg: "ogv URL"
}

iOS

{
    mp4: "mp4 URL",
    mov: "mov URL",
    "rawBytes": camera1.rawBytes
}

Android

{
    mp4: "mp4 URL",
    "rawBytes": camera1.rawBytes
}

The "camera1.rawBytes" in the above examples is the output from the voltmx.camera.rawBytes.

The following table lists the formats supported for different platforms.

Platform	Formats
SPA	MPEG 4 (mp4), webm, and ogv
Android	MPEG 4 and rawBytes
iOS	MPEG 4, MOV (mov), and voltmx.types.rawBytes

In the iOS and Android platforms, by default, mp4 format is selected as the source format even when other formats are defined. For example, if the source is defined as shown below, the application selects the mp4 format as the source and ignores other source files irrespective of order of the definition - that is, in the below example, even "rawBytes":camera1.rawBytes is defined at the beginning of the syntax, still the application selects the mp4 file as source.

"source": { 
      "rawBytes":camera1.rawBytes, 
      "mp4":"URL goes here", 
      "mov": ”URL goes here”
}

In the Android platform, the application selects the rawBytes as the source when the mp4 is not defined in the syntax.

In the iOS platform, when only mov and rawBytes source files are defined in the syntax, the application selects the mov format as the source. and rawBytes is selected as source when only rawBytes source file is defined in the syntax.

You can modify the source type using the setSource method.

Example

/*Sample code to set the source property of a Video widget where myCamera is a Camera widget in frmVideo Form.*/
frmVideo.myVideo.source = {
 "mp4": "http://www.quirksmode.org.html5/videos/big_buck_bunny.mp4",

top Property

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

The top property determines the position of the top 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 top edge of the parent container. In flow-vertical layout, the distance is measured from the bottom edge of the previous sibling widget in the hierarchy. In flow-horizontal layout, the distance is measured from the left edge of the parent container.

Type

String

Read/Write

Read + Write

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.

//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.*/

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;
