Hide taskbar and make window full screen

[tmparisi]

I would like to be able to make my application go completely full screen when it is run. This means that the windows taskbar/startbar should not be viewable and the window buttons (minimize, maximize, close) should also not be available. I want to keep employees from exiting out of the application and/or clicking on anything in the start bar. My current code looks like:

	public void start() {
		try {
			PlasticXPLookAndFeel.setMyCurrentTheme(new ExperienceBlue());
			UIManager.setLookAndFeel(new PlasticXPLookAndFeel());
			//UIManager.setLookAndFeel(new javax.swing.plaf.nimbus.NimbusLookAndFeel());
			UIManager.put("ComboBox.is3DEnabled", Boolean.FALSE);
		} catch (Exception e) {
		}

		rootView = RootView.getInstance();

		TransparentPanel panel = new TransparentPanel(new BorderLayout());
		panel.setOpaque(true);
		panel.add(rootView);

		posWindow.setContentPane(panel);
		posWindow.setSize(ApplicationConfig.getPreferences().getInt("wwidth", 900), ApplicationConfig.getPreferences().getInt("wheight", 650));
		Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
		posWindow.setLocation(ApplicationConfig.getPreferences().getInt("wlocx", ((screenSize.width - posWindow.getWidth()) >> 1)), ApplicationConfig.getPreferences().getInt("wlocy", ((screenSize.height - posWindow.getHeight()) >> 1)));
		posWindow.setMinimumSize(new Dimension(800, 600));
		posWindow.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
		posWindow.setVisible(true);

		initDatabase();
	}

What's the error/problem?

[tmparisi]

No error, just want to be able to hide the taskbar and the minimize/maximize/close buttons.

I added:

posWindow.setUndecorated(true);

to get rid of the frame buttons (minimize/maximize/close buttons) and now I need to figure out how to hide the taskbar, this way the program is effectively showing full screen.

Current code is as follows:

private Application() {
		applicationIcon = new ImageIcon(getClass().getResource("/icons/icon.png"));
		posWindow = new PosWindow();
                //Get rid of minimize,maximize,close buttons
                posWindow.setUndecorated(true);
		posWindow.setGlassPaneVisible(true);
		posWindow.setTitle(getTitle());
		posWindow.setIconImage(applicationIcon.getImage());
		posWindow.addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent e) {
				shutdownPOS();
				
			}
		});
	}

	public void start() {
		try {
			PlasticXPLookAndFeel.setMyCurrentTheme(new ExperienceBlue());
			UIManager.setLookAndFeel(new PlasticXPLookAndFeel());
			//UIManager.setLookAndFeel(new javax.swing.plaf.nimbus.NimbusLookAndFeel());
			UIManager.put("ComboBox.is3DEnabled", Boolean.FALSE);
		} catch (Exception e) {
		}

		rootView = RootView.getInstance();

		TransparentPanel panel = new TransparentPanel(new BorderLayout());
		panel.setOpaque(true);
		panel.add(rootView);

		posWindow.setContentPane(panel);
		posWindow.setSize(ApplicationConfig.getPreferences().getInt("wwidth", 900), ApplicationConfig.getPreferences().getInt("wheight", 650));
		Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
		posWindow.setLocation(ApplicationConfig.getPreferences().getInt("wlocx", ((screenSize.width - posWindow.getWidth()) >> 1)), ApplicationConfig.getPreferences().getInt("wlocy", ((screenSize.height - posWindow.getHeight()) >> 1)));
		posWindow.setMinimumSize(new Dimension(800, 600));
		posWindow.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
		posWindow.setVisible(true);

		initDatabase();
	}

Thanks, that seems to work except it causes 1 problem now:

I have a shutdown button that displays an 'are you sure?' type message.

public void shutdownPOS() {
		int option = JOptionPane.showOptionDialog(getPosWindow(), com.floreantpos.POSConstants.SURE_SHUTDOWN_, com.floreantpos.POSConstants.CONFIRM_SHUTDOWN, JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, null, null);
		if(option != JOptionPane.YES_OPTION) {
			return;
		}
		
		int width = posWindow.getWidth();
		int height = posWindow.getHeight();
		ApplicationConfig.getPreferences().putInt("wwidth", width);
		ApplicationConfig.getPreferences().putInt("wheight", height);

		Point locationOnScreen = posWindow.getLocationOnScreen();
		ApplicationConfig.getPreferences().putInt("wlocx", locationOnScreen.x);
		ApplicationConfig.getPreferences().putInt("wlocy", locationOnScreen.y);

		System.exit(0);
	}

When I click the 'shutdown' button now, the entire application minimizes into the taskbar. Once I click on its icon in the taskbar to bring it back up, the shutdown verification message is displayed.

Any idea why the entire application is minimizing?

My current code for the window looks like:

private Application() {
		applicationIcon = new ImageIcon(getClass().getResource("/icons/icon.png"));
		posWindow = new PosWindow();
                
                
                
                //Get rid of minimize,maximize,close buttons
                posWindow.setUndecorated(true);
                posWindow.setResizable(false);
                GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().setFullScreenWindow(posWindow); //Delete
                //posWindow.setVisible(true); //delete
                posWindow.setGlassPaneVisible(true);
		posWindow.setTitle(getTitle());
		posWindow.setIconImage(applicationIcon.getImage());
		posWindow.addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent e) {
				shutdownPOS();
				
			}
		});
	}

	public void start() {
		try {
			PlasticXPLookAndFeel.setMyCurrentTheme(new ExperienceBlue());
			UIManager.setLookAndFeel(new PlasticXPLookAndFeel());
			//UIManager.setLookAndFeel(new javax.swing.plaf.nimbus.NimbusLookAndFeel());
			UIManager.put("ComboBox.is3DEnabled", Boolean.FALSE);
		} catch (Exception e) {
		}

		rootView = RootView.getInstance();

		TransparentPanel panel = new TransparentPanel(new BorderLayout());
		panel.setOpaque(true);
		panel.add(rootView);

		posWindow.setContentPane(panel);
		
		posWindow.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
		posWindow.setVisible(true);

		initDatabase();
	}

Please help!

Well, there's a reason behind the word exclusive in the description of the API.

Exit full screen mode before you attempt to show the dialog.

db: So there is no other way to accomplish this full screen task besides this API? Unfortunately the open source application that I am customizing uses far too many dialogs, and using this full screen method makes the application unusable.

Is it better that I just hide the taskbar an then increase the size of the window? If so, how would this be accomplished, and small examples would be very much appreciated!
