JTabbedPane Tab组件的MouseEvents没有渗透 [英] MouseEvents for a JTabbedPane Tab component are not bleeding through

问题描述

我有一个带有自定义标签组件的 JTabbedPane 。该组件包含 JLabel （显示标签标题）和 JButton （关闭按钮）。当我更改 JLabel 中的文本时， JLabel 停止接收鼠标事件，我无法再选择该选项卡直接点击标签，如果我点击标签，然后我可以选择标签。有什么想法？

I have a JTabbedPane with a custom tab component. That component contains a JLabel (To display the tab title) and a JButton (A close button). When I change the text in the JLabel the JLabel stops receiving mouse events and I can no longer select that tab when I click directly on the label instead if I click around the label then I can select the tab. Any ideas?

代码片段：

class ShellPanelTabComponent extends JPanel implements ActionListener{

    private ShellPanel panel;
    private JLabel label;

    public ShellPanelTabComponent(final ShellPanel panel){
      super(new FlowLayout(FlowLayout.LEFT, 0, 0));
      this.panel = panel;
      setOpaque(false);

      label = new JLabel(panel.getTitle());
      label.setFocusable(false);
      add(label);
      label.setBorder(BorderFactory.createEmptyBorder(2,0,0,5));

      //now the button
      CloseButton closeButton = new CloseButton(panel);
      add(closeButton);
      closeButton.addActionListener(this);
    }

    public void actionPerformed(ActionEvent ae) {
      panel.getShell().removeShellPanel(panel);
    }

    /**
     * @return the label
     */
    public JLabel getLabel() {
      return label;
    }
  }

推荐答案

问题与我在进行更多挖掘后发布的问题有关：使用setToolTipText的解决方法鼠标事件？

The problem is related to the one that I posted here after I did more digging: Workaround for setToolTipText consuming mouse events?
