好的，所以我们制作了一个像俄罗斯方块一样的游戏，所以我得到了如何在JTable上放置一个块（我们使用JTable作为棋盘），现在我需要为游戏设置控件而我不知道怎么做。如何将块移动到左侧或右侧？我应该把它放在哪里？
这是代码
public class TetrisTable extends JFrame {
JFrame frame;
TestPane pane = new TestPane();
char ch;
public TetrisTable() {
pane.setTimer();
}
public void start() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
frame = new JFrame("WORD OF TETRIS");
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(pane);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
private JTable table;
private TetrisTabelModel model;
private int currentRow = 0;
private int currentColumn = 0;
private int blockHeight = 1;
private int blockWidth = 0;
public TestPane() {
model = new TetrisTabelModel();
table = new JTable(model);
table.setDefaultRenderer(Integer.class, new TetrisTabelCellRenderer());
table.setRowHeight(48);
Enumeration<TableColumn> columns = table.getColumnModel().getColumns();
while (columns.hasMoreElements()) {
TableColumn column = columns.nextElement();
column.setPreferredWidth(48);
column.setMinWidth(48);
column.setMaxWidth(48);
column.setWidth(48);
}
setLayout(new GridBagLayout());
add(table);
}
public void setTimer() {
Timer timer = new Timer(1500, new ActionListener() { //dropper
@Override
public void actionPerformed(ActionEvent e) {
int col = (model.getColumnCount() - blockWidth) / 2;
int row = currentRow - blockHeight;
if (row + blockHeight >= model.getRowCount()) {
((Timer) e.getSource()).stop();
} else {
drawShape(row, col, ' ');
currentRow++;
row = currentRow - blockHeight;
drawShape(row, col, ch);
System.out.println(ch);
}
}
public void drawShape(int row, int col, char color) { //naggawa ng shape
for (int index = 0; index < blockHeight; index++) {
if (row >= 0 && row < model.getRowCount()) {
switch (index) {
case 0:
case 1:
model.setValueAt(color, row, col);
break;
case 2:
model.setValueAt(color, row, col);
model.setValueAt(color, row, col + 1);
model.setValueAt(color, row, col + 2);
break;
}
}
row++;
}
}
});
timer.setRepeats(true);
timer.setCoalesce(true);
timer.start();
}
public class TetrisTabelModel extends AbstractTableModel {

}
}

这是GUI（主要）

答案 0 :(得分：0)
JFrame使用BorderLayout。
所以我猜你会把tetris板添加到框架的中心。
然后，对于控件，您可以将包含控件的面板添加到“LINE_START”，“LINE_END”，“PAGE_START”或“PAGE_END”，具体取决于您希望框架的外观。
阅读How to Use BorderLayout上Swing教程中的部分，了解更多信息和工作示例。
另外，不要在Swing应用程序中使用Label，TextField等。这些是AWT组件。相反，在使用Swing时，您应该使用JLabel，JTextField等。
