  • JPanel's child components paint/layout problem

    - by Tom Brito
    I'm having a problem that when my frame is shown (after a login dialog) the buttons are not on correct position, then in some miliseconds they go to the right position (the center of the panel with border layout). When I make a SSCCE, it works correct, but when I run my whole code I have this fast-miliseconds delay to the buttons to go to the correct place. Unfortunately, I can't post the whole code, but the method that shows the frame is: public void login(JComponent userView) { centerPanel.removeAll(); centerPanel.add(userView); centerPanel.revalidate(); centerPanel.repaint(); frame.setVisible(true); } What would cause this delay to the panel layout? (I'm running everything in the EDT) -- update In my machine, this SSCCE shows the layout problem in 2 of 10 times I run it: import java.awt.BorderLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.SwingUtilities; public class TEST { public static void main(String[] args) throws Exception { SwingUtilities.invokeAndWait(new Runnable() { @Override public void run() { System.out.println("Debug test..."); JPanel btnPnl = new JPanel(); btnPnl.add(new JButton("TEST")); JFrame f = new JFrame("TEST"); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.getContentPane().setLayout(new BorderLayout()); f.getContentPane().add(btnPnl); f.pack(); f.setSize(800, 600); f.setVisible(true); System.out.println("End debug test!"); } }); } } The button first appers in the up-left, and then it goes to the center. Please, note that I'm understand, not just correct. Is it a java bug? --update OK, so the SSCCE don't show the problem with you that tried till now. Maybe it's my computer performance problem. But this don't answer the question, I still think Java Swing is creating new threads for make the layout behind the scenes.

    - by MyHeadHurts
    So I am working on a gridview that uses the order number to order the table. However, my users are able to ad a row. What i want is something similar to pages that have the arrows next to each row and the user can click up if they want that row to go up. I also want it to change the actual number in the row column. for the one being moved and for the other one being affected. I hope i am being clear enough

  • C++ Logger-Should I use an ordinary xml parser?

    - by Jonathon
    I'm working on a logging system for my 2D engine, and I'm confused on how I should go about creating/editing the file, and how I should output that file. I've learned that XML is more of a data carrier rather than a data displayer like HTML is. I've read that I can use XML to HTML converters. One method I've thought about is writing characters to a file in HTML. Clarity on these matters is what I ask of you, stack overflow.

  • 'Unable to read symbols' error

    - by cannyboy
    When I 'Build and Go' on the device, the console shows: warning: Unable to read symbols for ""/Users/Steve/Blue/build/Debug-iphoneos"/Blue.app/Blue" (file not found). warning: Unable to read symbols for ""/Users/Steve/Blue/build/Debug-iphoneos"/Blue.app/Blue" (file not found). Is this something I should worry about? If so, where should I look to find the root of the issue? The app works OK, but I'm just worried that this might be an AppStore approval issue.
