jlabel

I have Java Swing application ToolTipMouseTest The critical line is label.setToolTipText("label" + i); . Once it is commented out very click on a label produces 2 mousePressed in console. With this line enabled click on labels would produce nothing. Is this expected behaviour or a bug? My goal is to show tooltips without disabling MouseListener from working. Almost SSCCE, but without imports: public class ToolTipMouseTest { public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { new ToolTipMouseTest(); } }); } public ToolTipMouseTest()

Is there a way to rotate Swing text such as in a JLabel between 0 and 360 (or between -180 and 180) degrees in 1 degree steps? Yes. Look at Graphics2D.rotate(). For a JLabel, I think you could override the paintComponent() method to call rotate(x), then call the existing paintComponent(), then call rotate(-x). e.g. protected void paintComponent(Graphics g) { Graphics2D g2 = ( Graphics2D )g; g2.rotate(theta); super.paintComponent(g2); g2.rotate(-theta); } I haven't tried this. You might need to add an offset, see Graphics2D.rotate(double theta, double x, double y) I do not believe that Swing

I need to create a label with Java Swing that is clickable and able to open the default browser on the desktop and redirect it to a specific url. My code is able to open up the browser but not redirecting it to the correct url (the default home page is loaded). My test code: import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.io.IOException; import java.net.*; public class LinkTest extends JFrame { public LinkTest() { JPanel p = new JPanel(); JLabel link = new JLabel("Click here"); link.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR)); link.addMouseListener

I have an icon in a JLabel as shown below: Is it possible to add another icon (e.g. a flag representing a country) between the color icon and the text? For example, I want to add an icon depicting the U.S. flag between the red icon and US . Thanks! Yes, use nested JLabel with BoxLayout in the container label: JLabel container = new JLabel(); container.setLayout(new BoxLayout(container, BoxLayout.X_AXIS)); JLabel icon1Label = new JLabel(); JLabel icon2Label = new JLabel(); icon1Label.setIcon(icon1); icon2Label.setIcon(icon2); container.add(icon1Label); container.add(icon2Label); Try

I have 6 JLabel and each is having a different instance of a mouselistener class attached. How to know which JLabel has been clicked ? These JLabel form a two dimentional array. John Snow You use getSource to get a refrence to the object which is clicked on: label1.addActionListener(new yourListener()); label2.addActionListener(new yourListener()); public class yourListener extends MouseAdapter{ public void mouseClicked(MouseEvent e){ JLabel labelReference=(JLabel)e.getSource(); labelReference.someMethod(); } } The easiest way I did something like that was, to use JButtons and make them look

After scratching around I found that it's best to implement a custom image component by extending a JLabel. So far that has worked great as I can add multiple "images" (jlabels without the layout breaking. I just have a question that I hope someone can answer for me. I noticed that in order to animate JLabels across the screen I need to setlayout(null); and setbounds of the component and then to animate eventually setlocation(x,y); . Is this a best practice or a terrible way to animate a component? I plan on eventually making an animation class but I don't want to do so and end up having to

I'm looking for a way to display the current date and time on a JFrame as a JLabel but have it update automagically. Once it is drawn to the pane, I shouldn't need to worry about manually updating it because it will refresh say, every 2 seconds. Is there a proper way of doing this? Instead of manually changing the JLabel's text value every 2 seconds. Use the javax.swing.Timer to ensure that updates to the Swing component occur on the EDT. Timer t = new javax.swing.Timer(2000, new ActionListener(){ @Override public void actionPerformed(ActionEvent e){ yourLabel.setText(...); } }); t.start();

I'm generating some JComponents in code and using the GridBag layout to arrange them. My layout consists of 12 rows and 3 columns, with each row consisting of a JSlider, a JCheckBox and a JLabel. Here's the code I'm using to generate the UI: final int NUM_MOTORS = 12; // This is the panel I'm adding the components to. pnlMotorSliders.setLayout(new GridBagLayout()); GridBagConstraints c = new GridBagConstraints(); for (int i = 0; i < NUM_MOTORS; ++i) { c.gridy = i; // Create the slider JSlider slider = new JSlider(SwingConstants.HORIZONTAL, 10, 4085, 10); c.fill = GridBagConstraints.HORIZONTAL;
