CollectionView Properties

Enables you to control accessibility behavior and alternative text for the widget.

For more information on using accessibility features in your app, refer the Accessibility appendix in the Quantum Application Design Guidelines Guide.

Syntax

accessibilityConfig

Type

JSON Object

Read/Write

Read + Write

Remarks

• The accessibilityConfig property is enabled for all the widgets which are supported under the Flex Layout.

NOTE: From Quantum Visualizer 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.

Accessibility in Components

• In a FlexForm containing direct widgets and components, while providing values to the aria-labelledby and the aria-describedby properties for widgets directly inside the FlexForm, you must not provide the Id of the widgets inside the components.
• In a component containing direct widgets and child components, while providing values to the aria-labelledby and the aria-describedby properties for widgets directly inside the component, you must not provide the Id of the widgets inside the child components.

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.
• The i18n key support in accessibilityConfig property depends on the languages supported by the TTS(Text-To-Speech) engine of the mobile device. If the TTS engine of the mobile device does not support a language, the text provided in the accessibilityConfig property is not read by the TTS engine.

Accessibility in Desktop Web Platform

• To use the accessibilityConfig property on the Desktop Web platform, ensure that you disable the Legacy JS Mode in the Project Settings > Responsive Web section.
• 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 Desktop web applications support only a few ARIA tags. To achieve more accessibility features, use the attribute a11yARIA. The tags added to a11yARIA will be added to the DOM.

• The tagName attribute supports the following tags in the Label Segment, FlexContainer, and FlexScrollContainer widgets:

  Widget Name	Supported tags	Example	Remarks
  Label	label(default) div span h1, h2, h3, h4, h5, h6	The following example shows how to assign the tags to the Label widget. /*Sample code to assign the span tag to the Label widget*/ "accessibilityConfig": { "tagName": "span" }
  Segment	ul(default) ol div table dl	The following example uses the role and tagName attributes to modify the HTML tag of Segment widget. /*Sample code to assign the div tag to the Segment widget*/ "accessibilityConfig": { "a11yARIA": { "role": "grid" }, "tagName": "div" }	You can assign values to the role attribute inside the a11yARIA only when you modify the tag to div. You can only assign the following values to the role attribute of a Segment widget: grid table and button.
  FlexContainer	div (default) th td tr dt dd	The following example uses the role and tagName attributes to modify the HTML tag of a FlexContainer widget. /*Sample code to assign the td tag to a FlexContainer widget*/ var flx = new kony.ui.FlexContainer({ "accessibilityConfig": { "tagName": "td" } });	This is a read-only property. When you specify the value as tr for the tagName property of a FlexContainer widget, ensure that you use the Flex Horizontal Layout Type. The height of the FlexContainer widget is inherited from the height of the child widgets present inside it.
  FlexScrollContainer	div (default) th td dt dd	The following example uses the role and tagName attributes to modify the HTML tag of a FlexScrollContainer widget. /*Sample code to assign the td tag to a FlexScrollContainer widget*/ var flx = new kony.ui.FlexScrollContainer({ "accessibilityConfig": { "tagName": "td" } });	This is a read-only property.

Example 1

This example uses the Login scenario to explain how to provide accessibility to the usernameText TextBox widget inside the frmLogin Form. The frmLogin form also contains the usernameLbl Label widget (with the text Username) and rulesLbl Label widget(that contains the username policies).

//This is a generic property that is applicable for various widgets.
/*Here, we have shown how to use the accessibilityConfig Property for a TextBox widget.You need to make a corresponding use of the accessibilityConfig property for other applicable widgets.*/
frmLogin.usernameText.accessibilityConfig = {
  "a11yLabel": "Label",
  "a11yValue": "Value",
  "a11yHint": "Hint",
  "a11yARIA": {
    "tabindex" /* Integer with no floating/decimal numbers*/: 1,
    "role" /*Prescribed string value as per wcag guidelines*/: "main",
    "aria-labelledby": "usernameLbl"
    "aria-describedby": "rulesLbl"
  }
};

Example 2

This example creates a Label widget (lblSpan) inside the frmSample FlexForm. This sample code uses the tagName property to change the HTML tag of the lblSpan Label from label tag to span tag.

/*Here, we have shown how to use the accessibilityConfig Property for a Label widget. You need to make a corresponding use of the accessibilityConfig property for in Segment widget as well.*/
var lblspan = new kony.ui.Label({
  "accessibilityConfig": {
    "tagName": "span"
  },
  "id": "lblspan",
  "isVisible": true,
  "left": "460dp",
  "skin": "CopyslLabel0b3521e51e03b44",
  "text": "span tag",
  "top": "92dp",
  "width": kony.flex.USE_PREFFERED_SIZE,
  "zIndex": 1
}, {
  "contentAlignment": constants.CONTENT_ALIGN_MIDDLE_LEFT,
  "padding": [0, 0, 0, 0],
  "paddingInPixel": false
}, {});

frmSample.add(lblspan);

Example 3

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": kony.i18n.getLocalizedString("key1")     
};
/*Sample code to implement internationalization in accessibilityConfig property in Desktop Web platform.*/

Form1.myButton.accessibilityConfig = {
    "a11yLabel": "kony.i18n.getLocalizedString(\"key3\")"
};

Specifies the set of values for each item.

Syntax

data

Array

Read/Write

Read Only

Remarks

The data is categorized into Sections and items. The Sections information is optional. You can set the data in three different formats.

• Format1: Set the data without any sections.
• Format 2: Set the data with sections where section header is a name.
• Format 3: Set the data with sections where header is driven by template.

The below table explains the type and description of template key:

Example

//Sample code to define data property for a CollectionView widget.
frmCollection.myCollection.data = [{
 "dataId1": "data1",
 "dataId2": "data2",
 "dataId3": "data3",
 "accessibilityConfig": "acObject"
}, {
 "dataId1": "datax",
 "dataId2": "datay",
 "dataId3": "dataz",
 "template": "box1",
 "accessibilityConfig": "acObject"
}];

Example of Format 1

[{
    "dataId1": "foo",
    "dataId2": "foo",
    "dataId3": "foo",
    "accessibilityConfig": "acObject"
}, {
    "dataId1": "bar",
    "dataId2": "bar",
    "dataId3": "bar",
    "template": "boxRef2",
    "accessibilityConfig": "acObject"
}, {
    "dataId1": "bar",
    "dataId2": "bar",
    "dataId3": {
        "isVisible" :true,
      "skin" : "nskin",
      "focusSkin": "fskin",
      "text" : "Foo"
    },
    "accessibilityConfig": "acObject"
}]

In the above example, template is the standard key which can be optionally to override the common itemTemplate provided with a specific template for the item. For template always the value has to be valid box reference, if not it falls back to the common itemTemplate. mentainfo is another standard key which can be used to specify meta information about the item. in iOS the specific standard parameter that metainfo can support isselectable.

In the above examples, the values of dataId1, dataId2 are shown as string, but dataId3 is key value pair. The key value pair format allows you to set the properties specific to the widget. In the above example, we are setting the isVisible property to ture and text property to "Foo", skin property with ID nskin and focusSkin to a skin with ID fskin. If a string is provided, typically is mapped to the text property for button and labels and the src property for the image.

Example of Format 2

/*set the data with sections where section header is a name. 
This example has two sections and each section with two rows.*/
[
    ["section1", [{
        "dataId1": "foo",
        "dataId2": "foo",

        "dataId2": "bar",
        "dataId3": "bar",
        "accessibilityConfig": "acObject"
    }], "acObject"]
]

Type

Array

Read/Write

Read + Write

Remarks

The index is with respect to the order in which data is set with data property.

Programmatically setting the selectedItem Index will not make any visible differences in the item, however it will bring the item at the index into the view able area on the screen.

Setting this value before the parent form is shown may result in the value not being changed. To avoid this you can set this value in the onDidFinishDataLoading callback for the CollectionView widget.

Setting this value it to null/nil clears the selection state.

The selectedItemIndex is not updated when clicked on any child widget of a itrem.

selectedItemIndex Array format:

[sectionIndex1, [itemIndex1],

For example,
[1,3] indicates 4th item in 2nd section.
[1,4] indicates 5th item in 2nd section.

If data contains the sections then the selectedIndex indicates the selected itemindex within the section.

Example

//Sample code to set the selectedItemIndex property for a CollectionView widget as four.

In case of MULTI_SELECT there can be more than one selected index and the array represents the same.

In case of SINGLE_SELECT and DEFAULT_BEHAVIOR the array contains only one element indicating the selectedIndex.

Setting it to null/nil clears the selection state and also sets the selectedIndices to null/nil.

The selectedItemIndices is not updated when clicked on any child widget of a item.

When this property is read from the SegmentedUI the list structure depends on the usage of sections.

selectedItemIndices Array format:

[
 [sectionIndex1, [itemIndex1, itemIndex2, ...],
 [sectionIndex3, [itemIndex4, itemIndex5, ...],
 .....
]

For example:

• [ [0, [2] ] ] indicates 3rd item is selected in the first selection.
• [ [0, [1, 4] ] ] indicates 2nd and 5th items are selected in the first section.
  
• [ [0, [0, 3] ], [2, [1, 3, 4] ] ] indicates the 1st, 4th items, of 1st section and also 2nd , 4th and 5th items in 3rd section.
  

NOTE: selectedItemIndices is not updated when a item is swiped in PAGE_VIEW or COVERFLOW_VIEW. It is updated only when clicked on a item.

Behavior when data is modified in the segment

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 and Android.
• 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.

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 Quantum Visualizer 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 Quantum Visualizer 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.

kony.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 kony.ui.FlexContainer({ 
  "id": "flx"
  "zIndex": kony.flex.ZINDEX_AUTO
});

//Sample code to set the ZIndex value to Auto
flx.zIndex = kony.flex.ZINDEX_AUTO;

Example

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