JavaFX Rectangle

In general, Rectangles can be defined as the geometrical figure consists of four sides, out of which, the opposite sides are always equal and the angle between the two adjacent sides is 90 degree. A Rectangle with four equal sides is called square.

JavaFX library allows the developers to create a rectangle by instantiating javafx.scene.shape.Rectangle class.

Properties

Property	Description	Setter Method
ArcHeight	Vertical diameter of the arc at the four corners of rectangle	setArcHeight(Double height)
ArcWidth	Horizontal diameter of the arc at the four corners of the rectangle	setArcWidth(Double Width)
Height	Defines the height of the rectangle	setHeight(Double height)
Width	Defines the width of the rectangle	setWidth(Double width)
X	X coordinate of the upper left corner	setX(Double X-value)
Y	Y coordinate of the upper left corner	setY(Double( Y-value)

Example 1:

package application;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
public class Shape_Example extends Application{

	@Override
	public void start(Stage primaryStage) throws Exception {
		// TODO Auto-generated method stub
	primaryStage.setTitle("Rectangle Example");
	Group group = new Group(); //creating Group 
	Rectangle rect=new Rectangle(); //instantiating Rectangle 
	rect.setX(20); //setting the X coordinate of upper left //corner of rectangle 
	rect.setY(20); //setting the Y coordinate of upper left //corner of rectangle 
	rect.setWidth(100); //setting the width of rectangle 
	rect.setHeight(100); // setting the height of rectangle 
	group.getChildren().addAll(rect); //adding rectangle to the //group 
	Scene scene = new Scene(group,200,300,Color.GRAY);
	primaryStage.setScene(scene);
	primaryStage.show();
}
public static void main(String[] args) {
	launch(args);
}

}

Output:

Rounded Corner Rectangle

We can make the corners of the rectangle round by just calling the instance setter methods setArcHeight() and setArcWidth(). It sets the height and width of the arc at the corners of Rectangle. The following example implements Rounded corner rectangle.

Example:

package application;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
public class Shape_Example extends Application{

	@Override
	public void start(Stage primaryStage) throws Exception {
		// TODO Auto-generated method stub
	primaryStage.setTitle("Rectangle Example");
	Group group = new Group();
	Rectangle rect=new Rectangle();
	rect.setX(20);
	rect.setY(20);
	rect.setWidth(100);
	rect.setHeight(100);
	rect.setArcHeight(35);
	rect.setArcWidth(35);
	rect.setFill(Color.RED);
	group.getChildren().addAll(rect);
	Scene scene = new Scene(group,200,300,Color.GRAY);
	primaryStage.setScene(scene);
	primaryStage.show();
}
public static void main(String[] args) {
	launch(args);
}

}
