I want to add an image (small icon) to the javax.swing.JFrame title bar. How can I do it? mre Since JPanel doesn't have a title bar, I'm assuming that you're referring to JFrame . That being said, use setIconImage(...) . Here is an example of using setIconImages() . import java.awt.Image; import javax.swing.*; import javax.imageio.ImageIO; import java.net.URL; import java.util.*; class FrameIcons { public static void main(String[] args) throws Exception { URL url16 = new URL("http://i.stack.imgur.com/m0KKu.png"); URL url32 = new URL("http://i.stack.imgur.com/LVVMb.png"); final List<Image>

I'm new to swing, and was wondering why sometimes my application comes up as blank, and sometimes it displays the components. It seems to be sporadic. There are no exceptions thrown or anything like that. It just frequently comes up as a blank JFrame. At times when I close the application and run it again, it shows the components correctly, but it mainly comes up as blank. Am I doing something wrong in the code? I'm using the Eclipse IDE, if it matters. Here's the code: import java.applet.Applet; import java.awt.BorderLayout; import java.awt.FlowLayout; import java.awt.GridLayout; import java

So, I was trying to make a rectangle move with a KeyEvent ( KeyListener ) and whenever I try to hit the key, the rectangle doesn't move. The rectangle is drawn, but whenever I hit the left and right keys, nothing happens. I have two classes, one is my main class with the keyEvents and the frame and the other, draws the rectangle and holds the function to move the rectangle. Here is my code: import java.awt.event.KeyEvent; import java.awt.event.KeyListener; import javax.swing.JFrame; public class mainFrame extends JFrame implements KeyListener{ mainDraw Draw = new mainDraw(); public void

I have a JFrame , which have some options. When OK button is pressed i want the same JFrame to clear the contents and add new contents. I have tried it but the problem is new JFrame is popped out. What am I doing wrong? import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.IOException; import java.net.InetAddress; import java.net.UnknownHostException; import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.*; public class GuiFrame extends JFrame { final JFrame f = new JFrame("Test"); public void Starter(){

How do I draw an Image to a JPanel or JFrame, I have already read oracle's tutorial on this but I can't seem to get it right. I need the image " BeachRoad.png " to be displayed on a specific set of coordinates. Here is what I have so far. public class Level1 extends JFrame implements ActionListener { static JLayeredPane EverythingButPlayer; static Level1 l1; public Level1() { EverythingButPlayer = new JLayeredPane(); BufferedImage img = null; try { img = ImageIO.read(new File("BeachRoad.png")); } catch (IOException e) { } Graphics g = img.getGraphics(); g.drawImage(img,0, 0,
