# Overview

Android iPhone iPad
Android iPhone iPad

An option dialog is created using Titanium.UI.createOptionDialog or Alloy <OptionDialog> element. See Examples below for usage.

This dialog is presented differently on each platform, as described below.

# Android

On Android, the dialog is shown in the middle of the display (not touching the edges), with the option items represented in a picker. The previously-selected, or default, item can be set on creation.

You can assign a Titanium.UI.View to the Titanium.UI.OptionDialog.androidView property to define a custom dialog UI and layout, or you can assign a set of options to the Titanium.UI.OptionDialog.options property, but not both. If both of these properties are set, the custom view will appear but the options will be hidden.

Buttons below the picker may be optionally defined using the buttonNames property. The click event returns a Boolean value to indicate whether either an option item or a button was clicked.

# iOS

The destructive property may be set for an item, to give a visual cue that selecting it results in an irreversible action. Option dialogs are automatically cancelled when the application is paused/suspended.

# iPhone

On iPhone, this dialog is shown at the bottom edge of the display, with the option items represented as vertical buttons.

# iPad

On iPad, this dialog is shown in the middle of the display, or as a popover-like dialog if another view or control is specified via an argument passed to the open() method.

Note that on iPad, the cancel button is not displayed -- users can cancel the dialog by clicking outside of the dialog.

# Caveats

Care should be taken not to define any properties that are not documented, as this may produce unexpected results. For example, setting a message property will prevent the picker of option items from being displayed on Android.

# Examples

# Dialog with 3 Options

Ti.UI.backgroundColor = 'white';
var win = Ti.UI.createWindow({
  title: 'Click window to test',
  backgroundColor: 'white'
});

var opts = {
  cancel: 2,
  options: ['Confirm', 'Help', 'Cancel'],
  selectedIndex: 2,
  destructive: 0,
  title: 'Delete File?'
};

win.addEventListener('click', function(e){
  var dialog = Ti.UI.createOptionDialog(opts).show();
});
win.open();

# Dialog with 2 Options and 1 Button on Android and 3 Options on iOS

var win = Ti.UI.createWindow({
  title: 'Click window to test OptionDialog',
  backgroundColor: 'white'
});

var opts = {
  title: 'Delete File?'
};

var isAndroid = Ti.Platform.osname === 'android';

if (isAndroid) {
  opts.options = ['Confirm', 'Cancel'];
  opts.buttonNames = ['Help'];
} else {
  opts.options = ['Confirm', 'Help', 'Cancel'];
}

var dialog;
win.addEventListener('click', function() {
  dialog = Ti.UI.createOptionDialog(opts);

  dialog.addEventListener('click', onSelectDialog);
  dialog.addEventListener('cancel', function(e) {
    alert('Dialog canceled! e.cancel = ' + e.cancel + ', e.index = ' + e.index);
  })

   dialog.show();
});

function onSelectDialog(e) {
  if (isAndroid) {
    if (e.button === false && e.index === 0) {
      alert('Confirm option selected! e.index = ' + e.index);
    }
    if (e.button === false && eventeindex === 1) {
      alert('Cancel option selected! e.index = ' + e.index);
    }
    if (e.button === true && e.index === 0) {
      alert('Help Button clicked! e.index = ' + e.index);
    }
  }
}

win.open();

# Alloy XML Markup

Previous example as an Alloy view. You can set Titanium.UI.OptionDialog.cancel and Titanium.UI.OptionDialog.destructive on a <Option/> tag.

optiondialog.xml:

<Alloy>
    <Window id="win" onClick="showOptions" title="Click window to test"
        fullscreen="false" onExit="true" backgroundColor="white">

        <!--
            The OptionDialog tag declares an option dialog,
            which will need to be opened by the controller.
        -->
        <OptionDialog id="dialog" title="Delete File?">

            <!-- The Options tag sets the options property. -->
            <Options>
                <Option destructive="true">Confirm</Option>
                <Option platform="ios">Help</Option>
                <Option cancel="true">Cancel</Option>
            </Options>

            <!-- The ButtonNames tag sets the Android-only buttonNames property. -->
            <ButtonNames>
                <ButtonName>Help</ButtonName>
            </ButtonNames>

            <!-- Add a View for the androidView property here. -->

        </OptionDialog>

        <!-- Add views here -->

    </Window>
</Alloy>

optiondialog.js:

function showOptions(){
    $.dialog.show();
}

# Properties

# androidView

Availability
0.8
androidView :Titanium.UI.View

View to load inside the message area, to create a custom layout.

On Android you can either define a custom view with this property, or you can assign a set of options to the options property, but not both. If you do, the custom view will appear but not the options you defined.

In an Alloy application you can specify this property with either an <AndroidView/> or <View/> element inside the <OptionDialog/> element, for example:

<Alloy>
    <OptionDialog id="dialog" title="Delete File?" onClick="clickCB">

        <!-- Add View or AndroidView for the androidView property -->
        <AndroidView platform="android" layout="vertical">
            <Label color="red" text="Warning!  This change is permanent and you cannot undo it!" />
        </AndroidView>

        <ButtonNames>
            <ButtonName>Confirm</ButtonName>
            <ButtonName>Cancel</ButtonName>
        </ButtonNames>
    </OptionDialog>
</Alloy>

# apiName READONLY

Availability
3.2.0
3.2.0
9.2.0
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
3.0.0
3.0.0
9.2.0
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

# buttonNames CREATION ONLY

Availability
0.8
buttonNames :Array<String>

List of button names.

This property creates buttons underneath the picker options. The dialog only supports up to three buttons.

# cancel

Availability
0.8
0.8
9.2.0
cancel :Number

Index to define the cancel option.

On iOS, set to -1 to disable the cancel option.

On iPad, the cancel option must be set to either -1 or the index of the last option. For example, if there are 3 options and one of them is a cancel button, the cancel button must be the last option (index 2). If cancel is set to a different value, the last entry in the options array is not displayed.

Note that the cancel button is never shown on iPad, since the user can cancel the dialog by clicking outside of the dialog.

Default: undefined (Android), -1 (iOS)

# destructive CREATION ONLY

Availability
0.8
9.2.0
destructive :Number

Index to define the destructive option, indicated by a visual cue when rendered.

Default: -1

# elevation

Availability
5.0.0
elevation :Number

Base elevation of the view relative to its parent in pixels.

The elevation of a view determines the appearance of its shadow. Higher elevations produce larger and softer shadows.

Note: The elevation property only works on Titanium.UI.View objects. Many Android components have a default elevation that cannot be modified. For more information, see Google design guidelines: Elevation and shadows.

# filterTouchesWhenObscured

Availability
9.3.0
filterTouchesWhenObscured :Boolean

Discards touch related events if another app's system overlay covers the view.

This is a security feature to protect an app from "tapjacking", where a malicious app can use a system overlay to intercept touch events in your app or to trick the end-user to tap on UI in your app intended for the overlay.

Setting this property to true causes touch related events (including "click") to not be fired if a system overlay overlaps the view.

Default: false

# hiddenBehavior

Availability
6.1.0
hiddenBehavior :Number

Sets the behavior when hiding an object to release or keep the free space

If setting hiddenBehavior to HIDDEN_BEHAVIOR_GONE it will automatically release the space the view occupied. For example: in a vertical layout the views below the object will move up when you hide an object with hiddenBehavior:Titanium.UI.HIDDEN_BEHAVIOR_GONE.

Defaults to Titanium.UI.HIDDEN_BEHAVIOR_INVISIBLE.

This API can be assigned the following constants:

# horizontalMotionEffect

Availability
7.3.0
9.2.0
horizontalMotionEffect :MinMaxOptions

Adds a horizontal parallax effect to the view

Note that the parallax effect only happens by tilting the device so results can not be seen on Simulator. To clear all motion effects, use the <Titanium.UI.clearMotionEffects> method.

# id

Availability
0.9
0.9
9.2.0
id :String

View's identifier.

The id property of the Ti.UI.View represents the view's identifier. The identifier string does not have to be unique. You can use this property with getViewById method.

# lifecycleContainer

Availability
3.6.0
lifecycleContainer :Titanium.UI.Window | Titanium.UI.TabGroup

The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.

If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.

# opaquebackground

Availability
3.2.0
9.2.0
opaquebackground :Boolean

Boolean value indicating if the option dialog should have an opaque background.

This property is useful to ensure that the option dialog will display contents properly on the iPAD idiom without ghosting when scrolling. This property is only respected on the iPAD idiom on iOS7 and above.

Default: false

# options CREATION ONLY

Availability
0.8
0.8
9.2.0
options :Array<String>

List of option names to display in the dialog.

On Android you can assign a set of options to the OptionDialog with this property, or assign a custom view to the androidView property, but not both. If you do, the custom view will appear but not the options you defined.

# persistent

Availability
3.0.0
3.0.0
9.2.0
persistent :Boolean

Boolean value indicating if the option dialog should only be cancelled by user gesture or by hide method.

This property is useful to ensure that the option dialog will not be ignored by the user when the application is paused/suspended.

Default: true
