imageicon

问题 ImageIcon icon= new ImageIcon("a.gif"); JLabel jLabel1=new JLabel(icon); jLabel1.setVisible(true); card1.add(jLabel1); I am a newbie to Java and I am facing a problem to add image in a panel in applet. My image is in the same folder. My applet is visible without any problem but only image is not displayed. 回答1: public void init() URL imageURL = new URL(getDocumentBase(), "a.gif"); Image image = getImage(imageURL); ImageIcon icon = new ImageIcon(image); // ... The ImageIcon constructor that

问题 so I have this JButtons to which I add Icons. The Icons are too large initially, so I resize them beforehand, and it works fine. Except that when I resize the window, the JButtons change size, but not the Icons, which is problematic. Is there a way to have an Icon just fill the JButton it is attached to? Bit of code to make it clearer: public JewelClass(){ setBackground (new Color (30,30,30)); addActionListener(this); setLayout(new GridLayout()); ImageIcon icon = new ImageIcon(src/carre.jpg);

问题 Ok so I've been researching this one quiet a bit. I am fairly new to java but thought that this one would be easy. Ive tried just about every way that has been answered on this site and still no luck, and usually when I look here I am able to find a answer that fits what I am looking for. Does anyone know how to change the Java icon in the top corner of the JFrame. I'm pretty positive that its not my file path either because all my images are in the same folder and they all work, this is the

问题 In Eclipse, when I run the code, this works: import javax.swing.ImageIcon; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; public class Main { public static void main(String[] args) { JFrame frame = new JFrame("test viewing images"); frame.setSize(600,300); frame.setLocationRelativeTo(null); // centered on monitor frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); /** * Menu Bar stuff */ JMenuBar menuBar; JMenu menu; JMenuItem

问题 Icon icon = new ImageIcon(getClass().getResource( "/img/icon.gif" ) ); aButton = new JButton("Its a button", icon); Is there some kind of method that can stop an animated from playing? I was thinking of assigning a static jpg of the gif, then when I hover, assign the animated gif, but I don't think there is an event for taking off mouse in MouseMotionListener so I can load back the static jpg. The gif loops in the button, however, if I hover over it, it disappears. How can I make the gif

问题 I've been trying to convert a ImageIcon to BufferedImage ... And I've had no luck. I have a pre-existing ImageIcon that needs to be converted to a Buffered Image for the vast amount of BufferedImage operations that exist. I have found a few ways, but all of them are hugely CPU intensive. 回答1: What's wrong with: BufferedImage bi = new BufferedImage( icon.getIconWidth(), icon.getIconHeight(), BufferedImage.TYPE_INT_RGB); Graphics g = bi.createGraphics(); // paint the Icon to the BufferedImage.
