repaint

I have built a tetris game. Now in that I have used a JPanel for displaying content and the blocks (using the paintComponents() method). The problem is whenever I try to call the tetris program from another JFrame it does not paint at all. The code for my tetris main menu is: import javax.swing.*; import sun.audio.AudioPlayer; import sun.audio.AudioStream; import java.awt.*; import java.awt.event.*; import java.io.FileInputStream; import java.io.InputStream; @SuppressWarnings("serial") public class Tetris_MainMenu extends JFrame implements ActionListener { @SuppressWarnings("unused") public

How to make repaint for JDialog in Swing? If I click on convert button in JDialog I need to change GUI design of JDialog but it's not happening? Is their any solution? _convertAction = new AbstractAction() { public void actionPerformed(ActionEvent e) { String para = new String(); _task.setBookTypeId(13); initComponents(); // validate(); // repaint(); setVisible(true); } }; I'm setting booking type id is 13 . if(_task.getBookTypeId()== 1){ String colnames[] = {"Leg","Departure", "Date","Time", "Arrival","Date", "Time","How","Aircraft","PIC","Copilot"}; MyTableModel mytablemodel = new

As soon a I use gradients in my code, the repaint isn't done while resizing I get something like that while resizing (black rectangles where it has been resized, see image in the link below). And when i stop resizing, everything is drawn again, but only then. if I don't use g2d.setPaint(gradient); I have a quick redraw http://gui-builder.com/C41142775162.rar public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D)g; //sample of the code GradientPaint gradient = new GradientPaint(startX, startY, greyColor1, endX, endY, new Color(120,120,120)); g2d.setPaint

I created a JFrame, and it contains a JPanel. I created a number of JLabels. I can add the JLabels to the JPanel, and display them correctly. But I want to implement them so as they displayed sequentially ; a time delay between each JLabel to be displayed. After searching the StackOverfLow, I tried some code, but it has no effect!. So How to use a timer to make components(Labels) displayed one after the other by setting a time delay. I Don't want a fix for my code particularly in the answer. Just show how to display any type of components in a delayed manner, each component displayed after a

I'm making a snapshot (via a ShaderEffectSource with live: false ) of an Item, but I'm sometimes (1 cases in 200) getting a blank snapshot. I'm making the snapshot based on a signal like this: Image { onStatusChanged: { if (status == Image.Ready) { snapshotter.makeSnapshot(); } } } This is just as an overall context. I won't post a testcase for now because it's a big app and I haven't yet isolated a testcase. That might be material for a future question. So I'm not asking "where's the bug in my code" yet. Instead I have a simple question that I think may help me fix the bug: Can I be notified

I asked this before, but only theoretically, without an SSCCE. Now, I've created one, and the problem persists. I'd like to know why paintComponent is not called on repaint(x, y, w, h) , but is called on repaint() . Two classes: SANDBOX import java.awt.Dimension; import java.awt.FlowLayout; import javax.swing.JFrame; public class Sandbox { public static void main(String[] args) { JFrame f = new JFrame(); f.setMinimumSize(new Dimension(800, 600)); f.setLocationRelativeTo(null); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setLayout(new FlowLayout()); // Add label f.getContentPane().add
