Threading
All data access should occur on background thread
JavaFX Script is currently single threadedNever create JavaFX objects on a background thread!
Use the Task APISubclass from JavaTaskBase

Writing a Custom Task
Step 1: Subclass from JavaTaskBase
Step 2: Create a Java implementation peer
Step 3: Callback from the peer to the task on completion
Step 4: Create FX objects, do FX work on the FX thread
Step 1: Subclass
public class LoginTask extends JavaTaskBase { public-init var username:String; public-init var password:String;
public-read var token:String; }
Step 2: Create Peer
public class LoginTaskImpl implements RunnableFuture { private JiraSoapService jira; private String username; private String password; String token;
public LoginTaskImpl(JiraSoapService jira, String username, String password) { this.jira = jira; this.username = username; this.password = password; }
public void run() throws Exception { token = jira.login(username, password); } }
Step 3: Callback
public class LoginTask extends JavaTaskBase, FinishedHandler { ... var impl:LoginTaskImpl;
override protected function create():RunnableFuture { impl = new LoginTaskImpl(jira, this, username, password) } }
Step 3: Callbackpublic class LoginTaskImpl implements RunnableFuture { ... private FinishedHandler handler;
public LoginTaskImpl(JiraSoapService jira, FinishedHandler handler, String username, String password) { ... this.handler = handler; }
public void run() throws Exception { token = jira.login(username, password); handler.backgroundWorkFinished(); } }
Step 4: FX
public class LoginTask extends JavaTaskBase, FinishedHandler { ... override public function backgroundWorkFinished():Void { FX.deferAction(function():Void { token = impl.token; }); } }

Progress Indicator
Small circular progress indicator
Bind directly to task.percentDone
Example:
var task = CustomTask { ... } ProgressIndicator { progress: bind task.percentDone }

TextBox
Single or Multiline (single style) text input
Useful for building other controlslike a search box
Example: var t:TextBox = TextBox { promptText: “Search” action: function() { startSearch(t.text); t.text = “”; } }

ListView
Horizontal or Vertical
Massively Scalable
Custom CellsDynamically variable row heights
Animated cells
Standard ListView
var list = ListView { items: [“Apples”, “Oranges”, “Pears”] }
Custom Cell
var list = ListView { items: [“Apples”, “Oranges”, “Pears”] cellFactory: function() { ListCell { node: ... } } }

CSS
CSS is our strategy for styling. If you use our UI Controls, you use CSS.
Caspian is our default CSS stylesheet
CSS is fast, and works on mobile, desktop, and tv
Stick to the spirit of HTML CSS, but do not be bound by it

Break control skins in stylable parts
In some ways similar to HTML CSS’s Box but not that same
Can be Rectangle with independently rounded corners or any arbitrary path
Can have multiple background fills, background images, border strokes and border images
Regions: Background Fills
Regions: Stroke Borders
Regions: ScrollBar
