Building mobile web apps with Mobello

Mobello
HTML5 and JavaScript Mobile Web App Framework

But…
inconsistent HTML5 support

lack of mobile components

Have a look…

Configurations

config.json

config({
require : ‘/main.js’,
classname : ‘HelloCtrl’,
title : ‘HelloWorld’,
icon : ‘icon.png’,
version : ‘1.0’,
vendor : ‘kt corp’
});

Source Code - that’s it!
main.js

$class(‘HelloCtrl’).extend(tau.ui.SceneController).define({
loadScene: function () {
var scene = this.getScene();
scene.add(new tau.ui.Button({
label: ‘Hello Mobello!’
}));
}
});

SceneController
 Load or create Scene
 Handle UI logic

Scene

SceneController

$class(‘demo.SceneCtrl’).extend(tau.ui.SceneController).define({
loadScene: function () { Create UI
var scene = this.getScene();
var btn = new tau.ui.Button({label: ‘Tap Me!’});
btn.onEvent(‘tap’, this.btnTapped, this);
scene.add(btn);
},

btnTapped: function (e, payload) { Event Handler
alert(‘btn tapped!’);
},
...
});

SequenceNavigator
 heuristic scene loading
 manage navigation history
SequenceNavigator

ContactList ContactInfo

SequenceNavigator
$class(‘ContactsNavigator’).extend(tau.ui.SequenceNavigator).define({
init: function () {
this.setRootController(new ContactList());
},
handleNav: function (info) {
this.pushController(new ContactInfo(info));
}
});

// Contact list
$class(‘ContactList’).extend(tau.ui.SceneController).define({
...
});

// user info
$class(‘ContactInfo’).extend(tau.ui.SceneController).define({
...
});

ParallelNavigator
 deterministic scene loading
 selective scene switching

Scene1 Scene2

ParallelNavigator
SceneCtrl2
SceneCtrl1

ParallelNavigator
$class(‘ParallelNavi’).extend(tau.ui.ParallelNavigator).define({
init: function () {
this.setControllers([new SceneCtrl1(), new SceneCtrl2()]);
},
});

$class(‘SceneCtrl1’).extend(tau.ui.SceneController).define({
...
});

$class(‘SceneCtrl2’).extend(tau.ui.SceneController).define({
...
});

Animation
var anim = new tau.fx.Animation({
from: {'background': 'red'},
to: {'background': 'yellow'}
}, { // options
duration: 2500,
iterationCount: 2,
delay: 1000
}
);

anim.animate(btn);

Transition
var tran = new tau.fx.Transition({duration: ‘1000ms’});
tran.setStyle(‘width’, ‘150px’);
tran.setStyle(‘height’, ‘200px’, {
timingFunction: ‘ease-out’, duration: ‘1500ms’
});

tran.animate(btn1)

Basics

var btn = new tau.ui.Button({label: ‘Touch’});

=
var btn = new tau.ui.Buttion();
btn.setLabel(‘Touch’);

var panel = new tau.ui.Panel({
components: [btn, ...]
});

btn.onEvent(tau.rt.Event.TAP, this.handleTap, this);
...

Button
var btn1 = new tau.ui.Button({
label: ‘default',
styleClass: {
type: ‘default’ // normal, dark, red, ...
}
});

...

var btn2 = new tau.ui.Button({
label: ‘rectangle’,
styleClass: {
shape: ‘rectangle’ // round, corner
}
});

Table
var tbl = new tau.ui.Table({
group: true,
indexBar: tau.ui.Table.INDEXBAR_EN
});

var cell = new tau.ui.TableCell({
title: ‘apple’,
groupName: ‘A’
}));

tbl.add(cell);
...

Carousel
var carousel = new tau.ui.Carousel({vertical:true});

var panel1 = new tau.ui.Panel({
styles: {backgroundColor: ‘red’}
});

var panel2 = new tau.ui.Panel({
styles: {backgroundColor: ‘orange’}
});
...

carousel.setComponents(
[panel1, panel2, ... ]
);

ActionSheet
var actionsheet = new tau.ui.ActionSheet({
popupTitle: ‘TEST’,
components: [
new tau.ui.Button({label: ‘button1’}),
new tau.ui.Button({label: ‘Button2’}),
new tau.ui.Button({label: ‘Button3’})
]
});

ScrollPanel

var panel = new tau.ui.ScrollPanel({
hScroll: false,
pullToRefresh: ‘down’,
styles: {backgroundColor: ‘black’,
width: ‘100%’, height: ‘50%’
}
});

Dialog
tau.alert(‘The TextArea class... ’, {title: ‘alert’});
tau.confirm(‘The TextArea class... ’, {title: ‘confirm’});
tau.prompt(‘Please enter your name’, {title: ‘prompt’,
placeholderLabel: ‘name...’,});

Forms
TextArea

DatePicker

TextField

Segmented Buttons

Theming
 Sass & Compass
 predefined themes
 default
