public class NewSimpleGUI
extends Frame
implements WindowListener, KeyListener

A simple (but growing) and extendible interactive graphical interface designed for novice Java programmers. It is recommended that you subclass this class when you build your first GUI programs. To make your program work, you'll need to override the paintStuff method, the handleKey method, and possibly the setCaption method. You should also call the setTitle() method that NewSimpleGUI inherits from Frame. You may also override any of the methods described in Java's WindowListener and KeyListener interfaces.

Your main() should construct a new object in your class and then call the begin() method for that object.

See Circles for a sample use of this class.

Constructors

o NewSimpleGUI

 public NewSimpleGUI()

Create a new window with a default title.

Methods

o begin

 public final void begin()

Run the GUI.

o setCaption

 public void setCaption(String caption)

Set the caption.

o handleKey

 public void handleKey(char key)

Deal with the user pressing a key on the keyboard. Quits if the user presses a q. This method should be overriden. If the user doesn't press a key you care about, you may want to to call super.handleKey(key).

o paintStuff

 public void paintStuff(Graphics g)

Paint stuff on the screen. Right now, just prints some sample text. This method should be overriden.

o paint

 public void paint(Graphics g)

Paint stuff on the screen.

Overrides:: paint in class Container

o keyPressed

 public void keyPressed(KeyEvent e)

Handle the user pressing a key. Right now, does nothing, but is included because this implements KeyListener.

o keyReleased

 public void keyReleased(KeyEvent e)

Handle the user releasing a key. Right now, does nothing, but is included because this implements KeyListener.

o keyTyped

 public void keyTyped(KeyEvent e)

Handle the user typing a key. Uses handleKey() to determine what to do.

o windowActivated

 public void windowActivated(WindowEvent we)

Handle the window becoming active. Right now, does nothing, but is included because this implements KeyListener.

o windowClosed

 public void windowClosed(WindowEvent we)

Handle the window finishing closing. Exits the program, since I don't know how to do anything else.

o windowClosing

 public void windowClosing(WindowEvent we)

Handle the window starting to close. Gets rid of the window.

o windowDeactivated

 public void windowDeactivated(WindowEvent we)

Handle the window becoming inactive. Right now, does nothing, but is included because this implements KeyListener.

o windowDeiconified

 public void windowDeiconified(WindowEvent we)

Handle the window becoming uniconified. Right now, does nothing, but is included because this implements KeyListener.

o windowIconified

 public void windowIconified(WindowEvent we)

Handle the window becoming iconified. Right now, does nothing, but is included because this implements KeyListener.

o windowOpened

 public void windowOpened(WindowEvent we)
