Titanium.UI.ButtonBar

viewAndroidiPhoneiPadmacOSsince Android 10.0.0, iPhone 0.8, iPad 0.8, macOS 9.2.0

An iOS button bar component.

Android	iOS

The button bar is a set of buttons joined into a single control. On iOS, you can set up the buttons with either a title or image, but not both. On Android, you can set up the buttons with a title, image, or both.

Use the Titanium.UI.createButtonBar method or <ButtonBar> Alloy element to create a button bar.

The TabbedBar control is a button bar where the last selected button mantains a pressed or selected state. The following discussion applies to both button bar and tabbed bar.

Examples

Simple 3 button button bar

const win = Ti.UI.createWindow();
const buttonBar = Titanium.UI.createButtonBar({
  labels:['One', 'Two', 'Three']
});
buttonBar.addEventListener('click', (e) => {
  console.log(`Clicked on button index: ${e.index}`);
});
win.add(buttonBar);
win.open();

<Alloy>
    <Window id="win">
        <ButtonBar id="buttonBar">
            <!-- The Labels tag sets the ButtonBar.labels property -->
            <Labels>
                <!-- Specify text with node text or the title attribute. -->
                <!-- Can also specify the enabled, image and width attributes. -->
                <Label>One</Label>
                <Label>Two</Label>

BooleanAndroidsince 12.4.0

Parameters	Type	Description
name	String	Name of the event.
callback	Callback<Titanium.Event>	Callback function to invoke when the event is fired. 4 fields bubbles Boolean True if the event will try to bubble up if possible. cancelBubble Boolean Set to true to stop the event from bubbling. source Object Source object that fired the event. type String Name of the event fired.

Parameters	Type	Description
animation	Titanium.UI.Animation \| Dictionary<Titanium.UI.Animation>	Either a dictionary of animation properties or an Animation object.
callback?	Callback<Object>	Function to be invoked upon completion of the animation.

Parameters	Type	Description
point	Point	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.
destinationView	Titanium.UI.View	View that specifies the destination coordinate system to convert to. If this argument is not a view, an exception will be raised.

Parameters	Type	Description
callback?	Callback<Titanium.Blob>	Function to be invoked upon completion. If non-null, this method will be performed asynchronously. If null, it will be performed immediately.
honorScaleFactor?	Boolean	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.

Event properties	Type	Description
x	Number	X coordinate of the event from the `source` view's coordinate system.
y	Number	Y coordinate of the event from the `source` view's coordinate system.
obscured	Boolean	Returns `true` if the long press passed through an overlapping window belonging to another app. 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.

Event properties	Type	Description
scale	Number	The scale factor relative to the points of the two touches in screen coordinates.
velocity	Number	The velocity of the pinch in scale factor per second.
time	Number	The event time of the current event being processed.
timeDelta	Number	The time difference in milliseconds between the previous accepted scaling event and the current scaling event.
currentSpan	Number	The average distance between each of the pointers forming the gesture in progress through the focal point.
currentSpanX	Number	The average X distance between each of the pointers forming the gesture in progress through the focal point.
currentSpanY	Number	The average Y distance between each of the pointers forming the gesture in progress through the focal point.
previousSpan	Number	The previous average distance between each of the pointers forming the gesture in progress through the focal point.
previousSpanX	Number	The previous average X distance between each of the pointers forming the gesture in progress through the focal point.
previousSpanY	Number	The previous average Y distance between each of the pointers forming the gesture in progress through the focal point.
focusX	Number	The X coordinate of the current gesture's focal point.
focusY	Number	The Y coordinate of the current gesture's focal point.
inProgress	Boolean	Returns `true` if a scale gesture is in progress, `false` otherwise.
