# Overview

The PreviewActionGroup is created by the Titanium.UI.iOS.createPreviewActionGroup method. You need to set the title property when creating a PreviewActionGroup object.

Use this class to configure a group of preview actions used in the Titanium.UI.iOS.PreviewContext. The actions are of the type Titanium.UI.iOS.PreviewAction.

For an example, see Titanium.UI.iOS.PreviewContext.

# Properties

# actions

Availability

5.1.0

actions :Array<Titanium.UI.iOS.PreviewAction>

The preview actions assigned to this preview action group.

Provides an array with elements of the type Titanium.UI.iOS.PreviewAction. Note: Apple does not allow adding a preview group to another preview group, so only one hirarchie level is allowed.

# apiName READONLY

Availability

5.1.0

apiName :String

The name of the API that this proxy corresponds to.

The value of this property is the fully qualified name of the API. For example, Titanium.UI.Button returns Ti.UI.Button.

# bubbleParent

Availability

5.1.0

bubbleParent :Boolean

Indicates if the proxy will bubble an event to its parent.

Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.

Default: true

Returns

Type: void

# applyProperties

Returns

Type: void

# removeEventListener

Availability

5.1.0

removeEventListener(name, callback) → void

Removes the specified callback as an event listener for the named event.

Multiple listeners can be registered for the same event, so the callback parameter is used to determine which listener to remove.

When adding a listener, you must save a reference to the callback function in order to remove the listener later:

var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);

To remove the listener, pass in a reference to the callback function:

window.removeEventListener('click', listener);

Parameters

Name	Type	Description
`name`	String	Name of the event.
`callback`	Callback<Titanium.Event>	Callback function to remove. Must be the same function passed to `addEventListener`.

Returns

Type: void
