所有选项卡末尾的按钮关闭窗口

Question

我有一个要求，将最小化和关闭按钮放在我的JTabbedPane结束的右角。为了清楚起见，圆圈区域是两个按钮，我需要（我有一个未修饰的帧）

任何人都可以请指导我如何实现这一目标？我的问题是（更多）按钮定位（在JTabbedPane上），而不是实现最小化/关闭的功能

谢谢！

Answer 1

所有添加到JTabbedPane中的组件都将被包装在标签中。这意味着将按钮直接添加到JTabbedPane是不可能的。如果您希望直接将关闭按钮和最小化按钮作为选项卡窗格的一部分（而不是稍微放在一边），我建议使用按钮将自定义选项卡组件（JTabbedPane.setTabComponentAt()）添加到选项卡窗格中。由于该按钮是该选项卡的唯一组件，选择实际的“选项卡”本身是不可能的，只有按钮事件会发生。使用JTabbedPane不可能修复选项卡的位置，这将导致这两个“按钮选项卡”在您选择的布局内浮动。在其左侧插入更多制表符会导致始终以关闭和最小化按钮结束制表符列表。

我得到了解决这个问题：只要把工具栏选项卡面板
