Java Reference
In-Depth Information
Once the random values are generated, they will be applied to the
Text
nodes,
which will be drawn onto the scene graph. The following code snippet applies position
(x, y), color (RGB), and rotation (angle in degrees) onto the
Text
node:
Text text = new Text(x, y, "Java 8 Recipes");
text.setFill(Color.rgb(red, green, blue, .99));
text.setRotate(rot);
root.getChildren().add(text);
You will begin to see the power of the scene graph API by its ease of use.
Text
nodes can be easily manipulated as if they were
Shapes
. Well, actually they are
Shapes
. Defined in the inheritance hierarchy,
Text
nodes extend from the
javafx.scene.shape.Shape
class and are therefore capable of doing interesting
things such as being filled with colors or rotated about an angle. Although the text is
colorized, this still tends to be somewhat boring. However, in the next recipe you will
learn how to change a text's font.
14-3. Changing Text Fonts
Problem
You want to change text fonts and add special effects to the
Text
nodes.
Solution 1
Create a JavaFX application that uses the following classes to set the text font and ap-
ply embedded effects to
Text
nodes:
•
javafx.scene.text.Font
•
javafx.scene.effect.DropShadow
•
javafx.scene.effect.Reflection
