Suppose I have a JPanel Called panel , and already with a paintComponent , I drew some shapes like rectangles. I can get a buffered image out of my panel like: int w = panel.getWidth(); int h = panel.getHeight(); BufferedImage bi = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB); Graphics2D g = bi.createGraphics(); panel.paint(g); ImageIO.write(bi1, "png", new File("test.png")); How can I get a High Resolution image out of my panel ? (the current output image is just based on the resolution of my JPanel in my monitor) I tried AffineTransform , but it doesn't do what I need. Note that I

I am trying to create a program that automatically searches for a text field on the screen and types a word repetitively into that text field. Is there any class that can find a text field? Or is there any way in which a text field can be found? Because I know that the Robot class can type text, I just need to either get the cursor onto the text field and use the mousePress() and mouseRelease() methods. Thanks Alex Lynch I can't directly give you a solution, but I messed around with some code and may be able to point you in the right direction. Java, as you probably know, runs in the JVM. This

Is there a way I can rig a PrinterJob in Java to NOT actually print to a printer so that I can get the graphics objects for each page? I tried setting the PrintService to null, but Java wouldn't allow that. This is so that I can retrieve an accurate Print Preview for the document without essentially rebuilding PrinterJobs functions from the ground-up in a different context. Here's the code for the print function in my program: public int print(Graphics graphics, PageFormat pageFormat, int page) throws PrinterException { deepCopyString = string; FontMetrics metrics = graphics.getFontMetrics

I have a method running on the EDT and within that I want to make it execute something on a new (non EDT) thread. My current code is follows: @Override public void actionPerformed(ActionEvent arg0) { //gathering parameters from GUI //below code I want to run in new Thread and then kill this thread/(close the JFrame) new GameInitializer(userName, player, Constants.BLIND_STRUCTURE_FILES.get(blindStructure), handState); } You can create and start a new Java Thread that executes your method from within the EDT thread : @Override public void actionPerformed(ActionEvent arg0) { Thread t = new Thread

I have a problem following from my previous problem . I also have the code SwingUtillities.invokeAndWait somewhere else in the code base, but when I remove this the gui does not refresh. If I dont remove it the error I get is: Exception in thread "AWT-EventQueue-0" java.lang.Error: Cannot call invokeAndWait from the event dispatcher thread at java.awt.EventQueue.invokeAndWait(Unknown Source) at javax.swing.SwingUtilities.invokeAndWait(Unknown Source) at game.player.humanplayer.model.HumanPlayer.act(HumanPlayer.java:69) The code in HumanPlayer.act is: public Action act(final Action[]

wondered if anyone could point me in the right directon, i have developed a pong game and it needs double buffering due to flickering. Iv tryed some of the post on here to try and make it work, but im still a beginner with the swing awt suff, any help would be amazing thanks. public class PongPanel extends JPanel implements Runnable { private int screenWidth = 500; private int screenHeight = 300; private boolean isPaused = false; private boolean isGameOver = false; private int playToPoints = 10; private Padel player1,player2; private Ball ball; private Thread gameThread; private Image dbImage;

I get RGB24 byte array and want to show it in Java. public void getByteArray(byte byteArray[]){ int count1 = 0; byte temp1 = 0; for (int i = 0; i < byteArray.length; i++) { //The order of RGB24 is red,green and blue.Change the //order to blue,green and red so that java can use TYPE_3BYTE_BGR to recognize it if (count1 == 0) { temp1 = byteArray[i]; count1++; } else if(count1 == 1) { //do nothing count1++; } else if(count1 == 2) { byteArray[i - 2] = byteArray[i]; byteArray[i] = temp1; count1=0; } } image = new BufferedImage(width, height, BufferedImage.TYPE_3BYTE_BGR); image.getWritableTile(0, 0

I've created an application using Swing with a text area (JTextArea). I want to create an "edit" menu, with options to cut and copy text from the text area, and paste text from the clipboard into the text area. I've seen a couple of ways to do this, but I wanted to know what the best way is. How should I implement the cut/copy/paste? Robin I would personally opt for re-using the standard cut, copy and paste actions. This is all explained in the Swing drag-and-drop tutorial: adding cut, copy and paste . The section about text components is the most relevant for you. A quick copy-paste of some
