Performance Memory Usage

7

bbUI.js
Time for a demo!

9

Configuration document
 Config.xml:
 <rim:navigation mode=“focus”/>
 <feature id=“blackberry.system.event” />
 <feature id=“blackbery.app” />

 If using dropdowns on BlackBerry 5/6/7:
 <feature id=“blackberry.ui.dialog” />

 If using menus
 <feature id=“blackberry.ui.menu”/>
 <feature id=“blackberry.app.event”/>
10

Toolkit Initialization

 Mandatory initialization using bb.init(myoptions)
 Should be the first code you run on your main page
myoptions = {
onbackkey: null, // Custom handler for back key on BlackBerry 5/6/7 smartphones
onscreenready: null, // Manipulate your screen before it's inserted into the DOM
ondomready: null, // Manipulate your screen after it's inserted into the DOM
bb10ActionBarDark: false, // If set to true, the action bar will use the dark theme
bb10ControlsDark: false, // If set to true, the controls and screen will use the dark theme
bb10ForPlayBook: false, // If set to true, PlayBook will be considered a BB10 device
bb10AccentColor: '#2D566F', // An accent color to be used for title bars and other areas
bb10HighlightColor: '#00A8DF„ // A highlight color to use when a user selects an item
}

11

Screens

 Each screen is an individual HTML fragment file
 data-bb-type=“screen”

 Transition effects

 Title bar
 Back button on PlayBook
 Appears as an action bar back button on BlackBerry 10

12

Screen Code

<div data-bb-type="screen" data-bb-title="My Screen">

<div data-bb-type="title"
data-bb-caption="Title bar caption"

</div>

<p> Hello World ! </p>

</div>

Screen Management

 App = Single page
 bbui-0.9.1.js/css files loaded once into this single page
 Screen = HTML fragment
 Screens loaded via AJAX

 Screen stack
 bb.pushscreen(…), bb.popscreen()
 bbUI.js traps HW “back” key to auto-close screens on BB5/6/7
 bbUI.js automatically handles “back” if you specify a back button
on PlayBook or BlackBerry 10
14

Screen Events

 onscreenready
 Assigned once, passed screen element
 Fires synchronously

 ondomready

});
</script>
</head>
<body onload="bb.pushScreen('menu.htm’,'menu');">
</body>
</html> 16

Styling & Scripting

 Screen specific CSS
 Inline OR linked (relative to app root)

 Dynamic resolution handling
 Fonts
 Images

 Screen specific JS
 Unload event fired if you need to do some clean-up

17

Alice.js
A Lightweight Independent CSS Engine

32

Framework Goals

 Visual effects library
 Hardware accelerated for fast animations and transitions
 Adds randomization to effects so they never go stale

 One line of code
 Apply an effect to any HTML element

 Open and collaborative
 http://blackberry.github.com/Alice
 Apache 2 license
33

AliceJS Philosophy

 Simplicity
 One line of code for any effect
 CSS likeness
 Easy to one day perhaps integrate in the standard
 DOM-level animations
 Not just for image galleries
 Rich
 Collection of effects
 Organics
 effects are always mysteriously slightly different

Alice.js
Time for a demo!

35

Using Alice.js
<html>
<body>
<img id="e1" src="images/logo.png" onClick="animate(‘e1’)">
<input id="e2" type="text" onClick="animate(‘e2’)" />

<script src="js/src/alice.core.js"></script>
<script src="js/src/alice.plugins.cheshire.js"></script>
<script>
var a = alice.init();

function animate(id) {
a.wobble([id], 10, "center", "1000ms", "ease-in-out");
}
</script>
</body>
</html>
36

CSS Likeness

JavaScript Code:
a.wobble(["e1", "e2"], {value: 20, randomness: 80}, "center",
{value: 1000, randomness: 20}, "ease-in-out");

Putting CSS glasses on, it could look like this:
#MyDiv {
animate-wobble: randomize(20deg, 80%) center randomize(1000ms, 20%) ease-in-out;
}

Or
#MyDiv {
animate-wobble-rotation: 5 80%;
animate-wobble-anchor: center;
animate-wobble-duration: 1000ms 20%;
animate-wobble-timing-function: ease-in-out;
}

15 OOTB Sub-Effects

Bounce RaceFlag
Dance Slide
Drain Spin
Fade Toss
Hinge Twirl
PageFlip Wobble
Pendulum Zoom
PhantomZone ...

Use the builder tool to create your own effects
