Hi I'm not such a professional at programming so i come here to ask how i can make this possible.
Issue: Client game is running once fullscreen mode clicked i want it to call setUndecorated() but cant while the frame is already visible.
I realized that i would need to create a new frame but im unsure how to transfer everything over, i have tried myself and all i get is a blank white screen of the new frame.
Here is my code:
public Jframe(String args[]) {
super();
try {
sign.signlink.startpriv(InetAddress.getByName(server));
initUI();
} catch (Exception ex) {
ex.printStackTrace();
}
}
public void initUI() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
JPopupMenu.setDefaultLightWeightPopupEnabled(false);
frame = new JFrame();
frame.setLayout(new BorderLayout());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setBackground(Color.BLACK);
gamePanel = new JPanel();
gamePanel.setLayout(new BorderLayout());
gamePanel.add(this);
JMenu fileMenu = new JMenu("Menu");
String[] mainButtons = new String[] { "-", "Donate", "-", "Vote", "-", "Hiscores", "-", "Forums", "-", "Exit"};
for (String name : mainButtons) {
JMenuItem menuItem = new JMenuItem(name);
if (name.equalsIgnoreCase("-")) {
fileMenu.addSeparator();
} else {
menuItem.addActionListener(this);
fileMenu.add(menuItem);
}
}
JMenuBar menuBar = new JMenuBar();
JMenuBar jmenubar = new JMenuBar();
Jframe.frame.setMinimumSize(new Dimension(773, 556));
frame.add(jmenubar);
menuBar.add(fileMenu);
frame.getContentPane().add(menuBar, BorderLayout.NORTH);
frame.getContentPane().add(gamePanel, BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
frame.setResizable(true);
init();
} catch (Exception e) {
e.printStackTrace();
}
I hope any of you can help i really appreciate thanks!
If this is for a game then most likely you don't want this. You should take a look at
http://download.oracle.com/javase/tutorial/extra/fullscreen/exclusivemode.html
I may be pointing out the obvious, as well as facilitating the wrong approach, but can't you just make it not visible then make it visible again?
i.e.
myFrame.setVisible(false);
myFrame.setUndecorated(true);
myFrame.setVisible(true);
However, there is a better approach, as "ghostbust555" pointed out.
This is the setFullScreenWindow() that answer was referring to:
public void goFullScreen() {
GraphicsDevice myDevice =
GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
// wrap in try because we don't want to lock the app in fullscreen mode
try {
myDevice.setFullScreenWindow(myFrame);
// do your stuff
...
} finally {
myDevice.setFullScreenWindow(null);
}
}

I would like to apply my own close and minimize buttons. Is there any way to change the JFrame design?
The trick lies in the PLAF and setDefaultLookAndFeelDecorated(true) (Specifying Window Decorations).
E.G.
import java.awt.BorderLayout;
import javax.swing.*;
public class FrameCloseButtonsByLookAndFeel {
FrameCloseButtonsByLookAndFeel() {
String[] names = {
UIManager.getSystemLookAndFeelClassName(),
UIManager.getCrossPlatformLookAndFeelClassName()
};
for (String name : names) {
try {
UIManager.setLookAndFeel(name);
} catch (Exception e) {
e.printStackTrace();
}
// very important to get the window decorations.
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame f = new JFrame(UIManager.getLookAndFeel().getName());
f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
JPanel gui = new JPanel(new BorderLayout());
f.setContentPane(gui);
JTree tree = new JTree();
tree.setVisibleRowCount(4);
gui.add(tree, BorderLayout.LINE_START);
gui.add(new JScrollPane(new JTextArea(3,15)));
JToolBar toolbar = new JToolBar();
gui.add(toolbar, BorderLayout.PAGE_START);
for (int ii=1; ii<5; ii++) {
toolbar.add(new JButton("Button " + ii));
if (ii%2==0) {
toolbar.addSeparator();
}
}
f.pack();
f.setLocationByPlatform(true);
f.setVisible(true);
}
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
new FrameCloseButtonsByLookAndFeel();
}
});
}
}
think you are after a JWindow
http://docs.oracle.com/javase/7/docs/api/javax/swing/JWindow.html
You can then create your own buttons which actions can minimize/close your window
The only thing I'm aware that can be done is to add a WindowListener to the JFrame and handle closing events in that listener. You can make virtually anything, like displaying dialogs or even cancelling the closing of the JFrame.
See this tutorial for more details about how to write such listeners.
As for minimizing: as far as I know, there is no way to control or modify such behaviour, it's completely controlled by the operating system.
The only way to change the aspect of the minimize/close/maximize buttons is to use a custom LookAndFeel and setting JFrame.setDefaultLookAndFeelDecorated (true);.
Set jframe undecorated.
Place a jlabel for each button.
Put own icon for each Btn.
Put mouseListeners for each jlabel and
specify code eg, System.exit(0);/set ICONIFIED option
So I'm going into GUI's in Java, and am trying to create a simple main menu for a timer. All is well until I've attempted to add a background for the GUI. Adding the background works, however all other components are now gone, (the button). How could I fix this?
EDIT: Here is my new code.
public class MainMenu {
// JFrame = the actual menu / frame.
private JFrame frame;
// JLabel = provides text instructions or information on a GUI —
// display a single line of read-only text, an image or both text and an image.
private JLabel background;
// JButton = button.
private JButton alarmClockButton;
// Constructor to create menu
public MainMenu() {
frame = new JFrame("Alarm Clock");
alarmClockButton = new JButton("Timer");
// Add an event to clicking the button.
alarmClockButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// TODO: CHANGE TO SOMETHING NICER
JOptionPane.showMessageDialog(null, "This feature hasn't been implemented yet.", "We're sorry!",
JOptionPane.ERROR_MESSAGE);
}
});
// Creating the background
try {
background = new JLabel(new ImageIcon(ImageIO.read(getClass()
.getResourceAsStream("/me/devy/alarm/clock/resources/Background.jpg"))));
} catch (IOException e) {
e.printStackTrace();
}
frame.setLayout(new FlowLayout());
frame.setContentPane(background);
frame.add(alarmClockButton);
frame.setComponentOrientation(ComponentOrientation.LEFT_TO_RIGHT);
frame.setVisible(true);
frame.setSize(450, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
alarmClockButton.setForeground(Color.RED);
}
}
Thank you!
frame.setContentPane(background);
You use the label as the content pane. The problem is that the label doesn't use a layout manager by default.
You need to add:
background.setLayout( new BorderLayout() ); // or whatever layout you want
frame.setContentPane(background);
Now you can add the button directly to the frame. You don't need the panel.
Or if you want to get fancy you can use the Background Panel which gives you the option to scale or tile the background image.
Instead of making the ContentPane as JLabel, you can wrap the JLabel in a JPanel, then add this JPanel as the ContentPane :
public class MainMenu {
public static void main(String[] args) {
new MainMenu();
}
// JFrame = the actual menu / frame.
private JFrame frame;
private JPanel panel;
private JPanel bkgPanel;
// JLabel = provides text instructions or information on a GUI —
// display a single line of read-only text, an image or both text and an
// image.
private JLabel background;
// JButton = button.
private JButton alarmClockButton;
// Constructor to create menu
public MainMenu() {
frame = new JFrame("Alarm Clock");
panel = new JPanel();
bkgPanel = new JPanel();
alarmClockButton = new JButton("Timer");
// Add an event to clicking the button.
alarmClockButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// TODO: CHANGE TO SOMETHING NICER
JOptionPane.showMessageDialog(null, "This feature hasn't been implemented yet.", "We're sorry!",
JOptionPane.ERROR_MESSAGE);
}
});
// Creating the background
try {
background = new JLabel(new ImageIcon(
ImageIO.read(getClass().getResourceAsStream("/me/devy/alarm/clock/resources/Background.jpg"))));
bkgPanel.add(background);
} catch (IOException e) {
e.printStackTrace();
}
frame.setContentPane(bkgPanel);
frame.add(panel);
panel.add(alarmClockButton);
frame.setVisible(true);
frame.setSize(450, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
alarmClockButton.setForeground(Color.RED);
}
}
I'm new to Java GUI, and am having issues displaying an image. My intention is to display a large image and allow the user to click on regions of the image to indicate where certain features are located. Anyway, I'm getting a rough start because I can't even get the image to appear, despite reading Oracle's explanation and other solutions.
I've created a JFrame and used its setContentPane() method to add a JPanel and JLabel. I use the setIcon() method of the JLabel to add an image to it, or at least that's my intention...
Any advice is appreciated, especially if there's a better way of doing this. I'll be using OpenCV to process images, and plan to convert them to Java image (or BufferedImage) before displaying them.
Here is the code. I left out the libraries to save space.
public class Pathology {
public static void main(String[] args) {
PrimaryFrame primaryFrame = new PrimaryFrame();
primaryFrame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE);
primaryFrame.setSize(1500, 900);
primaryFrame.setVisible( true );
primaryFrame.setContentPane(primaryFrame.getGui());
try {
primaryFrame.setImage(ImageIO.read(new File("C:\\Users\\Benjamin\\Pictures\\Pathology\\C\\001.png")));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
GUI Class:
public class PrimaryFrame extends JFrame{
//private JTextField textField1;
JPanel gui;
JLabel imageCanvas;
public PrimaryFrame() {
super( "Pathology-1" );
//setLayout(new FlowLayout());
//textField1 = new JTextField("Chup!", 50);
//add(textField1);
}
public void setImage(Image image) {
imageCanvas.setIcon(new ImageIcon(image));
}
public void initComponents() {
if (gui==null) {
gui = new JPanel(new BorderLayout());
gui.setBorder(new EmptyBorder(5,5,5,5));
imageCanvas = new JLabel();
JPanel imageCenter = new JPanel(new GridBagLayout());
imageCenter.add(imageCanvas);
JScrollPane imageScroll = new JScrollPane(imageCenter);
imageScroll.setPreferredSize(new Dimension(300,100));
gui.add(imageScroll, BorderLayout.CENTER);
}
}
public Container getGui() {
initComponents();
return gui;
}
}
Would you laugh at me if I'd tell you that you just have to put the primaryFrame.setVisible( true ); to the end of the main method? :)
For furture understanding, you don't have to call frame.setVisible(true) every time you want to add/update something in the frame (in an ActionListener, for example). Instead you can call frame.revalidate() and frame.repaint(). (Where frame can be replaced with the particular panel)
You need to setVisible(true) after the call to setImage():
primaryFrame.setImage(ImageIO.read(new
File("C:\\Users\\Benjamin\\Pictures\\Pathology\\C\\001.png")));
because any update to the GUI after setVisible() will not be shown.
That's it and the code should be like this:
public class Pathology {
public static void main(String[] args) {
PrimaryFrame primaryFrame = new PrimaryFrame();
primaryFrame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE);
primaryFrame.setSize(1500, 900);
primaryFrame.setContentPane(primaryFrame.getGui());
try {
primaryFrame.setImage(ImageIO.read(new File(
"C:\\Users\\Benjamin\\Pictures\\Pathology\\C\\001.png")));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
primaryFrame.setVisible( true );
}
}
I've already tried loads of code from Stack. For some reason it's just not setting the ImageIcon for my JFrame, the comments are other attempts that have not worked;I avoided calling super so that I could reference the JFrame -- GUIPhotoAlbum extends JFrame; code:
public GUIPhotoAlbum ()
{
super("PhotoAlbum");
ImageIcon img = new ImageIcon("Photos/albumIcon.png");
this.setIconImage(img.getImage());
/*
try{
setIconImage(ImageIO.read(new File("Photos/albumIcon.png")));
}catch(Exception e){
System.out.print("Didn't work.");
}
*/
setSize(875, 625);
this.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
this.setLayout(new BorderLayout(5, 5));
initComponents();
initMenuBar();
initTopPanel();
add(topPanel, BorderLayout.CENTER);
initBottomPanel();
add(bottomPanel, BorderLayout.SOUTH);
addListeners();
setLocationRelativeTo(null);
setVisible(true);
}
EDIT
I'm running the program like this, where I try to set the ImageIcon of JFrame in the GUIPhotoAlbum() constructor; here's the driver:
public class AlbumDriver
{
public static void main (String [ ] args)
{
SwingUtilities.invokeLater
(
new Runnable()
{
#Override
public void run()
{
GUIPhotoAlbum pa = new GUIPhotoAlbum();
}
}
);
}
}
What am I doing wrong here?
PS I've tried BufferedImage, ImageIcon, using File.. and I'm using a Mac
Mac does not support frame icons, as seen in this answer.
Use this to change Dock Image in mac:
File imageFile = new File("Your image Path");
Image image = ImageIO.read(imageFile);
Application.getApplication().setDockIconImage(image);
For windows use this:
YourFrameObject.setIconImage(image);
The problem is, you class appears to be extending from JFrame but you're creating a new instance of a JFrame and setting it's icon instead...
JFrame newFrame = new JFrame("PhotoAlbum");
ImageIcon img = new ImageIcon("Photos/albumIcon.png");
newFrame.setIconImage(img.getImage());
Don't create the second instance of the JFrame, there's no need for newFrame in this instance...
For example...
public GUIPhotoAlbum ()
{
super("PhotoAlbum");
ImageIcon img = new ImageIcon("Photos/albumIcon.png");
setIconImage(img.getImage());
/*
//when uncommented, exception is never thrown
try{
setIconImage(ImageIO.read(new File("Photos/albumIcon.png")));
}catch(Exception e){
System.out.print("Didn't work.");
}
*/
// Hint use pack instead, but only after
// You've finished adding the components to the frame
setSize(875, 625);
setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
setLayout(new BorderLayout(5, 5));
initComponents();
initMenuBar();
initTopPanel();
add(topPanel, BorderLayout.CENTER);
initBottomPanel();
add(bottomPanel, BorderLayout.SOUTH);
addListeners();
setLocationRelativeTo(null);
setVisible(true);
}
