Explain the Fill property of 2D shapes in JavaFX
The fill property specifies/defines the color with which the interior area of the shape is to be filled. You can fill a particular shape with the desired color using the fill() method of the javafx.scene.shape.Shape class.
By default, the value of this property for the shapes (objects) line, path and polyline are Color.BLACK and, for all the remaining shapes the default value of this property is null i.e. they will not be filled with any color (they will be left opaque).
Example
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Line;
import javafx.scene.shape.Polygon;
import javafx.scene.text.Font;
import javafx.scene.text.FontPosture;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class FillExample extends Application {
public void start(Stage stage) {
Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12);
Text label1 = new Text("Fill: Default");
label1.setFont(font);
label1.setX(260.0);
label1.setY(125.0);
Polygon rhombus1 = new Polygon(300.0, 0.0, 250.0, 50.0, 300.0, 100.0, 350.0, 50.0);
Text label2 = new Text("Filling Line");
label2.setFont(font);
label2.setX(60.0);
label2.setY(275.0);
//Constructing a line
Line line = new Line();
line.setStartX(50.0);
line.setStartY(200.0);
line.setEndX(150.0);
line.setEndY(200.0);
line.setStrokeWidth(10.0);
line.setFill(Color.DARKBLUE);
Text label3 = new Text("Fill: Blue");
label3.setFont(font);
label3.setX(270.0);
label3.setY(275.0);
Polygon rhombus3 = new Polygon(300.0, 150.0, 250.0, 200.0, 300.0, 250.0, 350.0, 200.0);
rhombus3.setFill(Color.BLUE);
Text label4 = new Text("Fill: Chocolate");
label4.setFont(font);
label4.setX(440.0);
label4.setY(275.0);
Polygon rhombus4 = new Polygon(490.0, 150.0, 440, 200.0, 490.0, 250.0, 540.0, 200.0);
rhombus4.setFill(Color.CHOCOLATE);
//Creating a Group object
Group root = new Group(label1, label2, label3, label4, rhombus1, line, rhombus3, rhombus4);
//Creating a scene object
Scene scene = new Scene(root, 595, 310);
//Setting title to the Stage
stage.setTitle("Fill Example");
//Adding scene to the stage
stage.setScene(scene);
//Displaying the contents of the stage
stage.show();
}
public static void main(String args[]){
launch(args);
}
}Output
