A tab instance for a TabGroup.
A TabGroup tab instance. Each tab includes a button and one or more windows, which
holds the "contents" of the tab. Users can select a tab by clicking on the tab button.
Use the Titanium.UI.createTab method or <Tab> Alloy element to create a tab.
Use TabGroup.setActiveTab to switch between tabs in a tab group. The Titanium.UI.currentTab property provides a global reference to the currently active tab.
The behavior of tabs and tab groups follows the platform's native navigation style, which varies significantly between platforms.
On iOS, the tab maintains a stack of windows. Windows on top of the stack can partially or totally obscure windows lower in the stack. Calling open opens a new window on top of the window stack. When a window is closed, either by the user or by code, the window is removed from the stack, making the previous window visible. The root tab window cannot be removed.
On iOS the tab controls are generally kept on screen to allow a user to
navigate inside the app. Tab controls are hidden when the user is performing a modal
task (for example, composing a message). In this case, the app should provide a button
in the navigation bar to return to the previous screen. On iOS, the window should also
be opened as modal. On iOS, The tab controls can also be hidden by opening the new window
with tabBarHidden set to true.
When closing a tab window in iOS, you should always use the Tab.close method to ensure that the tab group maintains its navigation state.
On Android, the tab does not maintain a stack of windows. Calling open opens a new, heavyweight window, which by default covers the tab group entirely. This seems quite different from the iOS model, but it is the standard model for Android applications. Users can use the Back button to close the window and return to the tab group.
On Android, tab windows can be closed using either
Tab.close or Window.close. Since
no window stack is maintained, only a single window opened using
Tab.open can be closed using Tab.close.
As on iOS, the root tab window cannot be closed.
In this example, we create a simple tab and add it to a tab group.
var window = Ti.UI.createWindow({
title: 'My Tab'
});
var tab = Ti.UI.createTab({
window: window,
title: 'My Tab',
icon: 'myicon.png'
});
tabGroup.addTab(tab);
Previous example an an Alloy view.
<Alloy>
<TabGroup id="tabGroup">
<Tab id="tab" title="My Tab" icon="myicon.png">
<Window id="window" title="My Tab" />
</Tab>
</TabGroup>
</Alloy>
true if this tab is active, false if it is not.
true if this tab is active, false if it is not.
The tab can be activated by setting the property, but since this property is platform-specific, using TabGroup.setActiveTab is recommended instead.
Icon URL for this tab when active.
Requires: iOS 5.0 and later
iOS 5.0 and later only.
If unspecified, iOS uses a tint color to indicate the active tab. See icon for more information.
If the icon provided is larger than [30 pixels (60 pixels in the retina variant)] (https://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/MobileHIG/IconsImages/IconsImages.html), this image will be scaled to fit.
On iOS prior to 5.0, the default tint color is always used and this property remains unset.
Defines if the active icon property of the tab must be used as a mask. This property is applicable on iOS 7 and greater.
Requires: iOS 7.0 and later
This is the equivalent of the iconIsMask property, but for the active icon. When this is true, the active icon is tinted with the color specified in tabsTintColor. When this is false the image is rendered as is, though the title of the tab is still tinted.
Default: true
Defines the color of the title of tab when it's active.
Requires: iOS 5.0 and later
The color of the title of the tab when it's active. If not defined, it will use the default tint color.
The name of the API that this proxy corresponds to.
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, Button
returns Ti.UI.Button.
Sets the color of the tab when it is inactive.
For information about color values, see the "Colors" section of Titanium.UI.
Default: Transparent
Overrides: Titanium.UI.View.backgroundColor
Disabled background color of the view, as a color name or hex triplet.
For information about color values, see the "Colors" section of Titanium.UI.
Default: Same as the normal background color of this view.
Disabled background image for the view, specified as a local file path or URL.
Default: If `backgroundDisabledImage` is undefined, and the normal background image `backgroundImage` is set, the normal image is used when this view is disabled.
Sets the color of the tab when it is focused.
On the Android platform, this sets the color of the active tab.
For information about color values, see the "Colors" section of Titanium.UI.
Default: Same as the normal background color of this view.
Overrides: Titanium.UI.View.backgroundFocusedColor
Focused background image for the view, specified as a local file path or URL.
For normal views, the focused background is only used if focusable is true.
Default: If `backgroundFocusedImage` is undefined, and the normal background image `backgroundImage` is set, the normal image is used when this view is focused.
Background image for the view, specified as a local file path or URL.
Default: Default behavior when `backgroundImage` is unspecified depends on the type of view and the platform. For generic views, no image is used. For most controls (buttons, text fields, and so on), platform-specific default images are used.
Selected background color of the view, as a color name or hex triplet.
For information about color values, see the "Colors" section of Titanium.UI.
focusable must be true for normal views.
Default: Background color of this view.
Selected background image url for the view, specified as a local file path or URL.
For normal views, the selected background is only used if focusable is true.
Default: If `backgroundSelectedImage` is undefined, and the normal background image `backgroundImage` is set, the normal image is used when this view is selected.
Badge value for this tab. null indicates no badge.
If this item displays a badge, this color will be used for the badge's background. If set to null, the default background color will be used instead.
Requires: iOS 10.0 and later
For information about color values, see the "Colors" section of Titanium.UI.
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
View's clipping behavior.
Setting this to Titanium.UI.iOS.CLIP_MODE_ENABLED enforces all child views to be clipped to this views bounds. Setting this to Titanium.UI.iOS.CLIP_MODE_DISABLED allows child views to be drawn outside the bounds of this view. When set to Titanium.UI.iOS.CLIP_MODE_DEFAULT or when this property is not set, clipping behavior is inferred. See section on iOS Clipping Behavior in Titanium.UI.View.
Default: Undefined. Behaves as if set to Titanium.UI.iOS.CLIP_MODE_DEFAULT.
Base elevation of the view relative to its parent in pixels.
Requires: Android 5 and later
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.
Icon URL for this tab.
Icon URL for this tab.
On iOS, tab icons are usually white with a transparent background. The system uses a transparent tint color to indicate whether the tab is active or inactive. In the inactive state, the tint color is based on the tab bar's color tabsBackgroundColor, which defaults to black. In the active state, the tint color is usually blue. Prior to Titanium 3.1, there was no way to override the default active icon tint.
Titanium 3.1 introduced some new ways to customize tab icons, which are supported in iOS 5.0 and above:
You can specify the active tab's tint color as activeTabIconTint.
You can set separate icon images for the active and inactive states. If
activeIcon is set, then icon is used in the
inactive state, and activeIcon is used in the active state. No default tint
is applied to either icon.
If the icon provided is larger than [30 pixels (60 pixels in the retina variant)] (https://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/MobileHIG/IconsImages/IconsImages.html), this image will be scaled to fit if used with activeIcon, and cropped at the bottom otherwise.
The icon inset or outset for each edge.
Use this property for example to center an icon without providing a title. To do that, set the
insets to {top:6} and/or {left:6}. The right and bottom are calculated internally to prevent the
icon from mutating.
Default: All insets are zero.
Defines if the icon property of the tab must be used as a mask. This property is applicable on iOS 7 and greater.
Requires: iOS 7.0 and later
When this property is true, the color data of the image specified as the icon is ignored and the image is used as an alpha mask. When this is false, the color data of the image is preserved.
Default: true
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
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.
When on, animate call overrides current animation if applicable.
If this property is set to false, the animate call is ignored if the view is currently being animated.
Default: undefined but behaves as false
The preview context used in the 3D-Touch feature "Peek and Pop".
Requires: iOS 9.0 and later
Preview context to present the "Peek and Pop" of a view. Use an configured instance of Titanium.UI.iOS.PreviewContext here.
Note: This property can only be used on devices running iOS9 or later and supporting 3D-Touch. It is ignored on older devices and can manually be checked using Titanium.UI.iOS.forceTouchSupported.
Background color of the wrapper view when this view is used as either Titanium.UI.ListView.pullView or Titanium.UI.TableView.headerPullView.
Default: Undefined. Results in a light grey background color on the wrapper view.

The view's tintColor. This property is applicable on iOS 7 and greater.
Requires: iOS 7.0 and later
This property is a direct correspondant of the tintColor property of UIView on iOS. If no value is specified, the tintColor of the View is inherited from its superview.
Default:
Defines the color of the title of tab when it's inactive.
Requires: iOS 5.0 and later

Root-level tab window. All tabs must have at least one root-level tab window.
Adds the specified callback as an event listener for the named event.
Name of the event.
Callback function to invoke when the event is fired.
Applies the properties to the proxy.
Properties are supplied as a dictionary. Each key-value pair in the object is applied to the proxy such that myproxy[key] = value.
A dictionary of properties to apply.
Closes the top-level window for this tab.
On iOS, this method should be used when closing a window opened from a tab, to correctly maintain the iOS tab group's navigation state. Note that the window to be closed must be passed in as a parameter:
myTab.close(tabWin);
On Android, this method does not take a window parameter.
myTab.close();
On Android, if a window has been opened in front of the tab using Tab.open,
a subsequent call to Tab.close is equivalent to calling close on that window.
No window stack is maintained, so only the most-recently opened window on a given
tab can be closed in this way.
All platforms accept an optional options parameter. The only supported property
for this dictionary is the animated flag, which specifies whether the window
close should be animated. animated is true by default.
Window to close. This parameter must be omitted on Android.
Dictionary of display and animation settings to use when closing the window.
Identical to the options parameter to Window.close.
iOS only supports the animated parameter.
Translates a point from this view's coordinate system to another view's coordinate system.
Returns null if either view is not in the view hierarchy.
Keep in mind that views may be removed from the view hierarchy if their window is blurred or if the view is offscreen (such as in some situations with Titanium.UI.ScrollableView).
If this view is a Titanium.UI.ScrollView, the view's x and y offsets are subtracted from the return value.
A point in this view's coordinate system.
If this argument is missing an x or y property, or the properties can not be
converted into numbers, an exception will be raised.
View that specifies the destination coordinate system to convert to. If this argument is not a view, an exception will be raised.
Finishes a batch update of the View's layout properties and schedules a layout pass of the view tree.
deprecated since 3.0.0
Use the <Titanium.Proxy.applyProperties> method to batch-update layout properties.
Since the layout pass scheduled is asynchronous, the rect
and size values may not be available immediately after
finishLayout is called.
To be notified when the layout pass completes, add a listener for the postlayout event.
Fires a synthesized event to any registered listeners.
Name of the event.
A dictionary of keys and values to add to the Titanium.Event object sent to the listeners.
Gets the value of the backgroundColor property.
Overrides: Titanium.UI.View.getBackgroundColor
Gets the value of the backgroundFocusedColor property.
Overrides: Titanium.UI.View.getBackgroundFocusedColor
Returns the matching view of a given view ID.
The ID of the view that should be returned. Use the id property in your views to
enable it for indexing in this method.
Inserts a view at the specified position in the children array.
Useful if the layout property is set to horizontal or vertical.
Pass an object with the following key-value pairs:
view (Titanium.UI.View): View to insertposition (Number): Position in the children array to
insert the view. If omitted, inserts the view to the end of the array.Opens a new window.
On iOS, the new window is opened as the top window in the tab's window stack. On Android, the new window is opened as a new, heavyweight window, obscuring the tab group.
Window to open.
Dictionary of display and animation settings to use when opening the window.
Identical to the options parameter to Window.open.
iOS only supports the animated parameter.
Closes all windows that are currently opened inside the tab.
Note that only the close event of the most recently opened window is fired.
Options supporting a single animated boolean property to determine whether the windows
will be animated while being closed (default: false).
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);
Name of the event.
Callback function to remove. Must be the same function passed to addEventListener.
Replaces a view at the specified position in the children array.
Useful if the layout property is set to horizontal or vertical.

Starts a batch update of this view's layout properties.
deprecated since 3.0.0
Use the <Titanium.Proxy.applyProperties> method to batch-update layout properties.
To prevent a layout pass each time a property is modified, call startLayout before
changing any properties that may change this view's layout. This initiates a batch update
mode where layout changes are deferred.
Call finishLayout to end batch update mode and trigger a layout pass. For example:
view.startLayout();
view.top = 50;
view.left = 50;
view.finishLayout();
Note that any property changes made during the batch update may be deferred until
finishLayout is called. This may vary somewhat by platform. For example, changing the
text of a label may trigger a layout pass. In iOS, updating the label text is
deferred.
See also: updateLayout, finishLayout, postlayout event.
Returns an image of the rendered view, as a Blob.
The honorScaleFactor method is only supported on iOS.
Function to be invoked upon completion. If non-null, this method will be performed asynchronously. If null, it will be performed immediately.
Determines whether the image is scaled based on scale factor of main screen. (iOS only)
When set to true, image is scale factor is honored. When set to false, the image in the blob has the same dimensions for retina and non-retina devices.
Performs a batch update of all supplied layout properties and schedules a layout pass after they have been updated.
deprecated since 3.0.0
Use the <Titanium.Proxy.applyProperties> method to batch-update layout properties.
This is another way to perform a batch update. The updateLayout method is called with a
dictionary of layout properties to perform the batch update. For example:
view.updateLayout({top:50, left:50});
This is equivalent to the following:
view.startLayout();
view.top = 50;
view.left = 50;
view.finishLayout();
See also: startLayout, finishLayout, postlayout event.

Name of the event fired.
True if the event will try to bubble up if possible.
Set to true to stop the event from bubbling.
Fired when this tab is clicked in the tab group.
There is a subtle difference between singletap and click events.
A singletap event is generated when the user taps the screen briefly without moving their finger. This gesture will also generate a click event.
However, a click event can also be generated when the user touches, moves their finger, and then removes it from the screen.
On Android, a click event can also be generated by a trackball click.

Fired when the device detects a long press.
A long press is generated by touching and holding on the touchscreen. Unlike a longclick,
it does not respond to the trackball button.
The event occurs before the finger is lifted.
A longpress and a longclick can occur together.
In contrast to a longclick, this event returns the x and y coordinates of the touch.

Fired when a layout cycle is finished.
This event is fired when the view and its ancestors have been laid out. The rect and size values should be usable when this event is fired.
This event is typically triggered by either changing layout properties or by changing the orientation of the device. Note that changing the layout of child views or ancestors can also trigger a relayout of this view.
Note that altering any properties that affect layout from the postlayout callback
may result in an endless loop.
