Hi, 請問一下,
我想用 GridBagLayout 排出下面的面版:
┌────┬────┬────┐
│Button 1│Button 2│Button 3│
├────┴─┬──┴────┤
│ Button 4 │ Button 5 │
└──────┴───────┘
我使用以下程式碼:
public static void main(String[] args)
{
JPanel panel = new JPanel();
panel.setLayout(new GridBagLayout());
JButton b1 = new JButton("Button 1");
JButton b2 = new JButton("Button 2");
JButton b3 = new JButton("Button 3");
JButton b4 = new JButton("Button 4");
JButton b5 = new JButton("Button 5");
GridBagConstraints c = new GridBagConstraints();
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
c.gridwidth = 2;
panel.add(b1, c);
c.gridx = 2;
panel.add(b2, c);
c.gridx = 4;
panel.add(b3, c);
c.gridx = 0;
c.gridy = 1;
c.gridwidth = 3;
panel.add(b4, c);
c.gridx = 3;
panel.add(b5, c);
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(panel);
frame.setSize(400, 400);
frame.setVisible(true);
}
結果出來變成:
┌────┬────┬────┐
│Button 1│Button 2│Button 3│
├────┼────┴────┤
│Button 4│ Button 5 │
└────┴─────────┘
我想半天仍不知我錯在哪裡,
所以想來請教板上的各位, 先謝謝了!
