The document discusses user experience (UX) design and CSS styling in JavaFX. It includes the following key points: 1. Don Norman discusses the importance of design and UX, noting that good design makes people happy and memorable experiences. 2. The document provides an overview of CSS support and styling in JavaFX, including how CSS maps to node properties, common syntax features, and differences from HTML CSS. 3. Examples are given of using CSS to style elements of a sample login screen user interface in JavaFX, including styling the overall dialog, background elements, form boxes, buttons and text.

4. So you don’t need to have everything perfect…
they do a really good job of making the lines [at
Disneyland] as bearable as possible. And that’s
what user experience design is about, it’s about
memories… that in the end, you love it.

14. CSS In JavaFX 2.0

15. Why CSS?
• CSS is a domain specific language
–Very good for declaring visual states
• CSS empowers designers
• CSS is a standard
• CSS is widely adopted
• Separation of concerns
• Interoperability
–Ability to use a single HTML stylesheet and have it
apply to the page + the applet
–Ability to have a single JavaFX stylesheet and have it
apply to the app + embedded HTML 15

16. What Is A Scene Graph?
• A directed acyclic graph (or tree)
–Each parent has 0 or more children
–Each child has at most a single parent
–There are no cycles (i.e. a-> b->a)
• Each node represents a visual element
–Rectangle
–Button
–Text
• Each node has visual state
–Transforms
–Paints 16

Scene
Button “Cancel”
Button “First”
Group
Button “Second” Button “Third”

18. The DOM vs. The Scene Graph
• The DOM is also a directed acyclic graph
• DOM nodes also have visual stat
• DOM mixes up semantic & visuals
–<div> vs. <b> vs. <em>
• The scene graph has custom layouts
–The DOM only uses the HTML Box model
• The APIs are quite different
–We like to think the scene graph is significantly better

20. JavaFX and CSS
Stage stage = new Stage();
Label label = new Label();
label.setText(“Hello World”);
stage.getScene().getContent().add(label);
stage.setVisible(true);
20

21. Showing The Label
21

22. Adding The CSS File
Stage stage = new Stage();
Label label = new Label();
label.setText(“Hello World”);
Scene scene = stage.getScene();
scene.getContent().add(label);
scene.getStylesheets().add(“/example.css”);
stage.setVisible(true);
22

23. The example.css File
.label {
-fx-font: bold 20pt “Amble”;
-fx-text-fill:
linear (0%, 0%) to (0%, 100%)
stops (0.0, red) (1.0, black);
}
23

24. Showing The Styled Label

25. CSS Primer: Syntax
25
Rule Selector DeclarationPseudoclass
.label : hover {
-fx-font: bold 20pt “Amble”;
-fx-text-fill:
linear (0%, 0%) to (0%, 100%)
stops (0.0, red) (1.0, black);
}

26. Syntax Of A Declaration
26
Attribute Value
-fx-font: bold 20pt “Amble”

27. What Is A “selector”?
• A pattern used to match a Node in the scene
–Match against the Node’s class, styleClass, id, and
pseudo-class state (hover, pressed, selected,
focused, etc)
27
Label { … } Matches any Node with class Label
(but not subclasses!)
.label { … } Matches any Node with styleClass “label”
#title { … } Matches any Node with id “title”
* { … } Matches any Node
.label:hover { … } Matches any Node with styleClass “label”
and “hover” equal to true

28. Adding A Button
Stage stage = new Stage();
Label label = new Label();
label.setText(“Hello World”);
Scene scene = stage.getScene();
scene.getContent().add(label);
Button button = new Button();
button.setText(“About”);
button.setGraphic(image(“/about_32.png”));
scene.getContent().add(button);
scene.getStylesheets().add(“/example.css”);
stage.setVisible(true); 28

29. Showing The Styled Label

30. Attributes => Node Properties
• CSS attribute names map 1:1 with a property on
a scene graph node
–Names are “css-ized”
–All names are prefixed with –fx-
30
-fx-text-fill setTextFill(Paint p)
-fx-fill setFill(Paint p)
-fx-font setFont(Font font)
-fx-scale-x setScaleX(float value)

31. Deviations From HTML CSS
• Attribute names differ
–HTML CSS has HTML specific attribute names
–JavaFX CSS has JavaFX specific attribute names
• JavaFX has more pseudoclasses
–Controls sometimes have custom pseudoclasses
–ToggleButton, Cell has a “selected” pseudoclass
–Cell has “even” and “odd” pseudoclasses
31

32. Additions To HTML CSS
• Lookup
• Color Functions
–derive
–ladder
• Gradients
• Multiple background fills
• Multiple borders
• Effects
–dropshadow
–innershadow
