# Titanium.UI.TabbedBar
A button bar that maintains a selected state.
# Overview
A tabbed bar is a button bar that
maintains a state (visually distinguished as a pressed or selected look).
It is closely related to the ButtonBar
control. See the description of
Titanium.UI.ButtonBar for information on styling tabbed bars and buttons
bars.
Use the Titanium.UI.createTabbedBar method to create a Tabbed Bar.
# Examples
# Simple Tabbed Bar with 3 items
var bb1 = Ti.UI.createTabbedBar({
labels: ['One', 'Two', 'Three'],
backgroundColor: '#336699',
style: Ti.UI.iOS.SystemButtonStyle.BAR,
width: 200,
height: 25,
top: 50
});
win.add(bb1);
# TabGroup like behavior for views instead of windows
var win = Ti.UI.createWindow({ layout: 'vertical' });
var tabbedBar = Ti.UI.createTabbedBar({
labels: ['One', 'Two', 'Three'],
backgroundColor: '#336699',
height: '10%',
width: Ti.UI.FILL
});
var scrollView = Ti.UI.createScrollView({
scrollingEnabled: false,
height: '90%',
scrollType: 'horizontal',
layout: 'horizontal'
});
for (i = 0; i < tabbedBar.labels.length; i++) {
scrollView.add( Ti.UI.createView({ backgroundColor: '#'+Math.random().toString(16).substr(-6)}))
}
tabbedBar.addEventListener('click', function(e) {
scrollView.scrollTo(e.index * win.rect.width, 0, {animated: true});
})
win.add(scrollView);
win.add(tabbedBar);
win.open();
# Properties
# labels
Array of labels for the tabbed bar.
The labels can be specified either using an array of strings, in which case each string defines the title for a button, or using an array of simple dictionary objects, BarItemType, which can specify title, image, width and enabled state for each button.
# style
Style of the tabbed bar.
Specify one of the constants:
For iOS:
Titanium.UI.iOS.SystemButtonStyle,
either PLAIN
, BORDERED
, or BAR
.
The BAR
style specifies a more compact style and allows the bar's background
color or gradient to show through.
For Android:
[Titanium.UI.TABS_STYLE_*]
In Android style is only supported in the creation dictionary
of the proxy.
Default: Titanium.UI.iOS.SystemButtonStyle.PLAIN for iOS, Ti.UI.TABS_STYLE_DEFAULT for Android
# Events
# click
Fired when a button is clicked.
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.
