This is my code : private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { Properties props = new Properties(); props.put("mail.pop3.host", "pop.gmail.com"); props.put("mail.pop3.user", "mymail@gmail.com"); props.put("mail.pop3.socketFactory", 995); props.put("mail.pop3.socketFactory.class", "javax.net

I designed an interface for the welcome screen with one JFrame included two JPanels (JPanel1 on right and JPanel2 on left). The buttons on the left is to switch the Panels in JPanel1. I want to press on a button to replace JPanel1 content with another JPanel but I don`t know how. Please help. Here is a very simple example of something that should approximate your description. On the left, we have a hug button to toggle the content of the right panel. On the right, you have a panel with a given border and a label. When you press the button, the content on the right is swapped with the other

How can you track the movement of a JFrame itself? I'd like to register a listener that would be called back every single time JFrame.getLocation() is going to return a new value. EDIT Here's a code showing that the accepted answered is solving my problem: import javax.swing.*; public class SO { public static void main( String[] args ) throws Exception { SwingUtilities.invokeAndWait( new Runnable() { public void run() { final JFrame jf = new JFrame(); final JPanel jp = new JPanel(); final JLabel jl = new JLabel(); updateText( jf, jl ); jp.add( jl ); jf.add( jp ); jf.pack(); jf.setVisible( true

I am trying to display two rotating wheels with diameter 512untis at different rates but i am not able to remove the previous drawn image graphics and set the rotated graphics at the correct position. For now i am doing a rotation with arbitrary angle. I tried affineTransform and got the rotations but it was weird like all pixels spread away. Im using a while loop with thread.sleep(). The following is the code : //The drawSmallCircle and drawBigCircle return two images. class MyFramePart2 extends JFrame { String name; JPanel big_obj_panel,small_obj_panel; JLabel bigLabel,smallLabel

How would I go upon adding JLabel hovering? Like when you move your mouse over top a JLabel a and new image will overlap it. I know how to make it work with buttons, but the same technique will not work for JLabel s. Will anyone guide me towards adding JLabel hovering? Please and thanks. package src; import java.awt.Dimension; import javax.swing.ImageIcon; import javax.swing.JFrame; import javax.swing.JLabel; /* * @Author - 0x29A * * */ public class Jframe { public static void main(final String args[]) { /* * @Images */ final ImageIcon icon = new ImageIcon("Data/button.png"); final JLabel

This is my current RectangleComponent class and I add it to a panel in my main JFrame but it never appears. I thought it wasn't drawing so I decided to call the paintComponent method in the Rectangle's constructor, and after sorting through 4-5 nullPointerExceptions, nothing has changed. I've read multiple guides on how to draw rectangles and I have seen multiple code examples, but I can never get the panels to work with more than one JComponent. If you could, please take a brief look at my code and see if you can devise a solution. Thank you for your time. Also listed is the Frame I call the

I need to have a undecorated JFrame( setUndecorated(true) ) which need to be shown fullscreen, without overlapping with the taskbar. I have tried the below solutions. Calling setExtendedState(MAXIMIZED_BOTH). Advantage : This works fine as expected, i.e., the window is getting adjusted itself dynamically, except it has the below issues. Issues Initially the window occupies the fullscreen Though the frame get adjusted itself dynamically, it overlaps with the taskbar. Tried the below solution as stated in Does JFrame.setExtendedState(MAXIMIZED_BOTH) work with undecorated frames?
