I just became aware that AWT / Swing under Java JDK 1.7 (as of JDK 7u15) does not support Retina displays on Apple Macbook Pros. Netbeans, for example, is nearly unbearable to use for more than a few minutes running on a Retina display and using JDK 1.7. This has been somewhat addressed in a StackExchange question here , and quoting one specific post: Apple's Java 6 JRE will support HiDPI, however it is not currently supported by Oracle's Java 7 JRE. It also doesn't work under the latest dev builds of Java 8. Swing and JavaFX apps are blurry on a Retinia MacBook. This is why IntelliJ still

So I have defined a mouseEventlistener and mousemotionListener to define points as so. protected Point elementPosition = null; public Point endPoint = null; public Axis tempAxis; public Graphics g; class MouseButtonHandler extends MouseAdapter { public void mousePressed(MouseEvent e) { if(e.getModifiers()==InputEvent.BUTTON1_MASK) { elementPosition =new Point(e.getX(), e.getY()) ; if(addType==YLABEL) { YDialog ydia = new YDialog(anApp); ydia.setVisible(true); value =(double) ydia.getValue(); ydia.dispose(); } } } public void mouseReleased(MouseEvent e) { } } class MouseMoveHandler extends

How to give this button background to be as jbutton i want to give this button metal color or grediant color how to make that? import java.awt.*; import java.awt.event.*; RoundButton - a class that produces a lightweight button. Lightweight components can have "transparent" areas, meaning that you can see the background of the container behind these areas. @SuppressWarnings("serial") public class RoundButton extends Component { ActionListener actionListener; // Post action events to listeners String label; // The Button's text protected boolean pressed = false; // true if the button is

public class KL implements KeyListener { public static void main(String[] args) { final JPopupMenu popup = new JPopupMenu(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(300, 200); frame.setVisible(true); } @Override public void keyPressed(KeyEvent arg0) { System.out.println(arg0.getKeyChar()); } @Override public void keyReleased(KeyEvent e) { System.out.println(e.getKeyChar()); } @Override public void keyTyped(KeyEvent e) { System.out.println(e.getKeyChar()); } } That's my class, it's probably something really stupid on my part, but my KeyListener here is not working.

I want to get the data from my textfield and set it to int h. and have that change the size of the rectangle im drawing, but im not sure how to go get the data from the textfield, I tired using e.getsource in actionperfomred but it cannot find my textfield. My code is below: import java.awt.*; import java.awt.event.*; import java.awt.image.*; import java.io.*; import javax.imageio.*; import javax.swing.*; import java.net.*; import java.sql.*; import java.lang.Object; import java.awt.Graphics; import java.awt.Graphics2D; /** * This class demonstrates how to load an Image from an external file *

I am currently working on a 2D shooter with moving background. The background is just a simple image. I want to implement that the image is moving endless from top to bottom. I thought about determining the part of the image that is at the bottom outside the visible part of the frame and paint it on the top again. @Override public void paint(Graphics go) { Graphics2D g = (Graphics2D) go; g.fillRect(0, 0, this.getWidth(), this.getHeight()); g.drawImage(this.imgBackground, 0, this.yBackground, this); } yBackground is the coordinate where the upper left corner of the image is drawn. It is altered

so I have two classes testPanel and testFrame. All the buttons are in the testPanel class. I want to add ActionListeners to the Jbuttons in the testFrame class. How do I go about doing this? testPanel: public class testPanel extends JPanel{ JLabel codeLbl = new JLabel("Code"); JLabel titleLbl = new JLabel("Title"); JLabel priceLbl = new JLabel("Price"); JTextField codeTxt = new JTextField(20); JTextField titleTxt = new JTextField(20); JTextField priceTxt = new JTextField(20); JButton addBtn = new JButton("Add"); JButton updateBtn = new JButton("Update"); JButton delBtn = new JButton("Delete");

I am confused regarding the display of components in a JPanel. Suppose if I create a custom JPanel with translucency of 0.8f as follows :- JPanel panel=new JPanel(){ @Override public void paint(Graphics g) { super.paint(g); BufferedImage img=(BufferedImage)createImage(getWidth(),getHeight()); Graphics2D g2=(Graphics2D) g.create(); g2.setComposite(AlphaComposite.SrcOver.derive(0.8f)); g2.drawImage(img,0,0,null); } @Override public Dimension getPreferredSize() { return new Dimension(300,300); } }; Now I set it as the contentPane of the frame. frame.setContentPane(panel); Now I add some buttons

I have working with swing API for the first time to get the screen resolution for my win application. How to set present screensize in Java Swing? The question depends. Do you want the full screen size or the usable screen size (minus things like the taskbar and the dock)? Do you want the default screen or a specific screen? Full Screen Size, any device... First you need to grab a reference to the current GraphicsEnvironment ... GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); Then you can grab a list of the GraphicsDevice s available on the system... GraphicsDevice
