我正在尝试使用Java Swing (GridBagLayout)创建一个控制台。

我不知道为什么，但正如您在左边距看到的那样，网格没有正确的大小。

其中浅蓝色是列表，绿色是图像，橙色是文本面板，黄色是文本字段。

我不知道如何使列表更大，图像更小。同样，文本字段的网格绑定到列表 1，即使列表在 y 1 上，文本字段在 y 2 上。

下面是一些代码。

// Command List
DefaultListModel<String> listInput = new DefaultListModel<String>();
JList<String> list = new JList<String>(listInput);
list.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
JScrollPane scrollPane = new JScrollPane(list);
list.setBackground(new Color(160, 160, 160));
list.setSelectionBackground(new Color(150, 150, 150));
scrollPane.setPreferredSize(new Dimension(20, 20));
manager.setCommandList(listInput);

    c.insets = new Insets(2, 2, 2, 2);
    c.ipady = 0;
    c.ipadx = 100;
    c.gridx = 0;
    c.gridy = 1;
    c.gridwidth = 1;
    c.gridheight = 2;
    c.weightx = 0.1;
    c.weighty = 0.6;
    c.fill = GridBagConstraints.BOTH;
console.add(scrollPane, c);

// Image Displayer
JLabel image = new JLabel(new ImageIcon());
manager.setImageField(image);

    c.insets = new Insets(0, 0, 0, 0);
    c.ipady = 0;
    c.ipadx = 0;
    c.gridx = 0;
    c.gridy = 0;
    c.gridwidth = 1;
    c.gridheight = 1;
    c.weightx = 0.1;
    c.weighty = 0.3;
    c.fill = GridBagConstraints.BOTH;
console.add(image, c);

其中'c'是网格包约束并控制主JPanel。如您所见，列表的网格高度为2，权重为0.6，图像的网格高度为1，权重为0.9，因此不确定为什么列表比图像小4倍。

另一个问题，我已经在持有图像的JLabel中添加了一个侦听器（在调整大小时），无论如何，它没有被调用。我应该将侦听器添加到主面板吗？因为图像只由布局管理器调整大小。

谢谢^^
