问题
The below is on the way to providing the results I am looking for, but unfortunately when this displays there is a large gap between tables on each page. It is so that I can only fit two of them on the screen per tab (with just two rows per table).
private void display() {
JFrame f = new JFrame("Test");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(new JLabel("Test"));
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
class ResultsPanel extends JPanel implements ActionListener {
private ArrayList<Venue> venueList;
private Timer timer;
QueueItem[] queue;
Reporter reporter;
private JPanel resultsPane1;
private JPanel resultsPane2;
private JTable[] table1;
private JTable[] table2;
private int totalItems;
public String[] page1ColumnNames = {
"Name",
"Wins",
"Losses",

"Win %",
"Avg Turns"};
public String[] page2ColumnNames = {
"Name",
"H%Total",
"H%inRange",
"KO/F rcvd",
"KO/F Infl",
"HChances",
"HitsTotal",
"Wounds Inflicted",
"Wounds Received"};
public String[][] page1Data = new String[2][6];
public String[][] page2Data = new String[2][9];
public void initResults() {
timer = new Timer(500, this);
timer.start();
}
@Override
public void actionPerformed(ActionEvent e) {
Object src = e.getSource();
try {
Thread.sleep(1);
} catch (InterruptedException d) {
System.err.println("Caught : InterruptedException" + d.getMessage());
}
repaint();
}

How would I go about fixing this? Thanks
Edit: Edited to add full code per request... most of it is irrelevant to what is going on here. Also removed setPreferredSize, but still same result.
Edit 2:
FYI, the blank spot in "Draws" is unrelated.
回答1:
Absent a complete example, it's hard to be sure what you're seeing. Given that one should avoid setPreferredSize(), note that JTable implements Scrollable and can calculate it's own preferred size. Unfortunately, the arbitrary Dimension calculated may be causing the problem. Overriding getPreferredScrollableViewportSize() to return a multiple of getRowHeight(), for example, may be a useful alternative.
