Class ClickMe

java.lang.Object

javafx.application.Application

intro.ClickMe

public class ClickMe
extends javafx.application.Application

All JavaFX programs extend a core class named Application, which provides the basic functionality of the program. When you extend the Application class, you must override a start method; JavaFX calls this method when the application starts. Like any Java program, a JavaFX program must have a main method. In a JavaFX program, the main method simply calls the launch method of the Application class, which in turn launches the application and calls the start method.

public ClickMe()

Method Detail

main

public static void main(java.lang.String[] args)

Like any Java program, a JavaFX program must have a main method. In a JavaFX program, the main method simply calls the launch method of the Application class, which in turn launches the application and calls the start method.

Parameters:

args - No command line arguments needed for this program.

start

public void start(javafx.stage.Stage primaryStage)

The start method is an abstract method, which means that there is no default implementation provided as a part of the Application class. Therefore, you must provide your own version of the start method. The start method is responsible for building and displaying the user interface.

Specified by:

start in class javafx.application.Application

Parameters:

primaryStage - the main (or primary) stage for this application, onto which the scene can be set.

buttonClick

public void buttonClick()

The action that will happen upon clicking the button

setupControls

private void setupControls(javafx.scene.layout.BorderPane pane)

Method to establish properties of controls

Parameters:

pane - The layout pane into which the controls will be placed
