2D Shapes Path Element - Arc
The Path Element Arc is used to draw an arc to a point in the specified coordinates from the current position.
It is represented by a class named ArcTo. This class belongs to the package javafx.scene.shape.
This class has 4 properties of the double datatype namely −
X − The x coordinate of the center of the arc.
Y − The y coordinate of the center of the arc.
radiusX − The width of the full ellipse of which the current arc is a part of.
radiusY − The height of the full ellipse of which the current arc is a part of.
To draw the Path element arc, you need to pass values to these properties This can be done by passing them to the constructor of this class, in the same order, at the time of instantiation as follows −
ArcTo arcTo = new ArcTo(x, y, radius, radiusY);
Or, by using their respective setter methods as follows −
setX(value); setY(value); setRadiusX(value); setRadiusY(value);
Steps to draw PathElement Arc
To draw an arc to a specified point from the current position in JavaFX, follow the steps given below.
Step 1: Creating a Class
Create a Java class and inherit the Application class of the package javafx.application. You can then implement the start() method of this class as follows.
public class ClassName extends Application { @Override public void start(Stage primaryStage) throws Exception { } }
Step 2: Create the path class object
Create the Path Class Object as shown in the following code block.
//Creating a Path object Path path = new Path();
Step 3: Create a Path
Create the MoveTo path element and set the XY coordinates to the starting point of the line to the coordinates (100, 150). This can be done using the methods setX() and setY() of the class MoveTo as shown below.
//Moving to the starting point MoveTo moveTo = new MoveTo(); moveTo.setX(100.0f); moveTo.setY(150.0f);
Step 4: Creating an Object of the Class ArcTo
Create the path element quadratic curve by instantiating the class named ArcTo, which belongs to the package javafx.scene.shape as shown below −
//Creating an object of the class ArcTo ArcTo arcTo = new ArcTo()
Step 5: Setting Properties to the Arc Element
Specify the x, y coordinates of the center of the ellipse (of which this arc is a part of). Then you can specify the radiusX, radiusY, start angle, and length of the arc using their respective setter methods as shown below.
//setting properties of the path element arc arcTo.setX(300.0); arcTo.setY(50.0); arcTo.setRadiusX(50.0); arcTo.setRadiusY(50.0);
Step 6: Adding Elements to the Observable List of Path Class
Add the path elements MoveTo and arcTo, created in the previous steps to the observable list of the Path class as follows −
//Adding the path elements to Observable list of the Path class path.getElements().add(moveTo); path.getElements().add(cubicCurveTo);
Step 7: Creating a Group Object
Create a group object by instantiating the class named Group, which belongs to the package javafx.scene.
Pass the Line (node) object created in the previous step as a parameter to the constructor of the Group class. This can be done in order to add it to the group as shown below −
Group root = new Group(line);
Step 8: Creating a Scene Object
Create a Scene by instantiating the class named Scene which belongs to the package javafx.scene. To this class, pass the Group object (root) created in the previous step.
In addition to the root object, you can also pass two double parameters representing height and width of the screen along with the object of the Group class as follows −
Scene scene = new Scene(group ,600, 300);
Step 9: Setting the Title of the Stage
You can set the title to the stage using the setTitle() method of the Stage class. The primaryStage is a Stage object which is passed to the start method of the scene class as a parameter.
Using the primaryStage object, set the title of the scene as Sample Application as follows.
primaryStage.setTitle("Sample Application");
Step 10: Adding Scene to the Stage
You can add a Scene object to the stage using the method setScene() of the class named Stage. Add the Scene object prepared in the previous steps using this method as shown below −
primaryStage.setScene(scene);
Step 11: Displaying the Contents of the Stage
Display the contents of the scene using the method named show() of the Stage class as follows.
primaryStage.show();
Step 12: Launching the Application
Launch the JavaFX application by calling the static method launch() of the Application class from the main method as follows.
public static void main(String args[]){ launch(args); }
Example
Following is a program that draws an arc from the current point to a specified position using the class Path of JavaFX. Save this code in a file with the name ArcExample.java.
import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.stage.Stage; import javafx.scene.shape.ArcTo; import javafx.scene.shape.MoveTo; import javafx.scene.shape.Path; public class ArcExample extends Application { @Override public void start(Stage stage) { //Creating an object of the class Path Path path = new Path(); //Moving to the starting point MoveTo moveTo = new MoveTo(); moveTo.setX(250.0); moveTo.setY(250.0); //Instantiating the arcTo class ArcTo arcTo = new ArcTo(); //setting properties of the path element arc arcTo.setX(300.0); arcTo.setY(50.0); arcTo.setRadiusX(50.0); arcTo.setRadiusY(50.0); //Adding the path elements to Observable list of the Path class path.getElements().add(moveTo); path.getElements().add(arcTo); //Creating a Group object Group root = new Group(path); //Creating a scene object Scene scene = new Scene(root, 600, 300); //Setting title to the Stage stage.setTitle("Drawing an arc through a path"); //Adding scene to the stage stage.setScene(scene); //Displaying the contents of the stage stage.show(); } public static void main(String args[]){ launch(args); } }
Compile and execute the saved java file from the command prompt using the following commands.
javac ArcExample.java java ArcExample
On executing, the above program generates a JavaFX window displaying an arc, which is drawn from the current position to the specified point, as shown below.
