java - 无法在 JPanel 中添加标签

Question

我想在 JPanel 内添加标签。

下面是代码和屏幕。

JPanel tableListPanel = new JPanel(new BorderLayout(5, 5));
        tableListPanel.setPreferredSize(new Dimension(150, 100));
        tableListPanel.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createEmptyBorder(0, 5, 5, 5),
                BorderFactory.createTitledBorder("Added Tables")));

        PosButton btnRemoveTable = new PosButton("REMOVE");

      // code to add lable.
      tableListPanel.add(new JLable("Test")):

Answer 1

更改此行:

tableListPanel.add(new JLabel("Test")):

对于:

tableListPanel.add(new JLabel("Test"), BorderLayout.WEST): 
//You can also use BorderLayout.EAST, BorderLayout.NORTH or BorderLayout.SOUTH

编辑:

可能还想更改此设置(仅当第一个更改本身不起作用时):

JPanel tableListPanel = new JPanel(new BorderLayout(5, 5));

对于:

JPanel tableListPanel = new JPanel(new BorderLayout());

将 JLable 更改为 JLabel。
