Java Swing - JTable not showing
flowlayout, java, jpanel, jtable, swing
Solution
if I remove the controlPanel at the top, it sometimes shows and sometimes not.
everything is hidden in `Server.getSongTableModel()`, nobody knows without posting an SSCCE with hardcoded value returns from
GUI has issue with Concurency in Swing
XxxModel loading data continiously with building GUi, then exception caused described problems
The code that I use inside my constructor of my JTable is provided in the same application, so it's no network error
no idea what you talking about
have to create an empty GUI, see InitialTread
showing GUI, then to start loading data to JTable
then starting Workers Thread (Backgroung Task) from `SwingWorker` or (descr. Network issue) better `Runnable#Thread` (confortable for catching an exceptions and processing separate threads)
output from `Runnable` to the Swing GUI must be wrapped into `invokeLater()`
Problem
I'm having some troubles with Java Swing. I'm trying to make a frame with a control panel at the top with some buttons in it. and below that i want a JTable to show I've been trying but the table is not showing. If I remove the controlPanel at the top, it sometimes shows and sometimes not. The code that I use inside my constructor of my JTable is provided in the same application, so it's no network error ``` public ServerMainFrame(GuiController gc){ this.gc = gc; initGUI(); } private void initGUI() { System.out.println("initiating GUI"); createFrame(); addContentPanel(); addControls(); //openPopUpServerSettings(); addSongTable(); } private void createFrame() { this.setTitle("AudioBuddy 0.1"); this.setVisible(true); this.setDefaultCloseOperation(EXIT_ON_CLOSE); this.setSize(800, 600); this.setResizable(false); this.setLocationRelativeTo(null); } private void addContentPanel() { JPanel p = new JPanel(); p.setLayout(new FlowLayout()); p.setSize(new Dimension(800, 600)); this.setContentPane(p); } private void addControls() { JPanel controlPanel = new JPanel(); controlPanel.setLayout(new FlowLayout()); controlPanel.setBorder(BorderFactory.createLineBorder(Color.black)); controlPanel.setSize(700,100); // Buttons JButton play = new JButton("Play"); JButton pause = new JButton("Pause"); JButton stop = new JButton ("Stop"); JButton next = new JButton("Next"); JButton prev = new JButton("Previous"); controlPanel.add(play); controlPanel.add(pause); controlPanel.add(stop); controlPanel.add(next); controlPanel.add(prev); // Currently playing JLabel playing = new JLabel("Currently playing:"); controlPanel.add(playing); JLabel current = new JLabel("Johnny Cash - Mean as Hell"); controlPanel.add(current); this.getContentPane().add(controlPanel); } private void addSongTable() { JTable songTable = new JTable(Server.getSongTableModel()); songTable.setVisible(true); JPanel tablePanel = new JPanel(); tablePanel.setVisible(true); tablePanel.add(songTable); songTable.repaint(); this.getContentPane().add(tablePanel); JButton btnMulticastList = new JButton("send list to clients"); btnMulticastList.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { Server.MulticastPlaylist(); } }); getContentPane().add(btnMulticastList); } ```
