我想在JTabbedPane上方的右上方添加按钮和标签。

您可以通过使用适当的布局嵌套Components来在JTabbedPane上方添加Container。例如，要在JTabbedPane的上方和右上方放置JLabel和JButton，您可以使用BoxLayout - 在mouseClicked实现中添加JTabbedPane：

pane.removeAll();
Box vert = Box.createVerticalBox();
Box top = Box.createHorizontalBox();
top.add(Box.createHorizontalGlue());
top.add(new JLabel("Top Label"));
top.add(new JButton("Top Button"));
vert.add(top);
vert.add(tabbed);
pane.add(vert);
....

您的要求不明确，因此您可能必须使用背景颜色和边框位置（例如，将边框添加到vert而不是tabbed）以满足您的要求。

如何在边框中添加按钮？
