我正在尝试将带有“X”按钮的标题栏添加到应用程序中。我已经读过Java中的Look& Feel,但我不知道我缺少什么(我刚刚创建了一个桌面应用程序,添加了一个JFrame表单,并且拖了一个表 - 没有逻辑)。

答案 0 :(得分:2)
I just created a Desktop Application, added a JFrame Form,
and dragged'n'dropped some buttons - no logic yet
有这些标准Top-Level Containers
JFrame
- &gt;有三个按钮最小化,最大化和关闭
JDialog
- &gt;只有一个按钮关闭
JWindow
- &gt;默认情况下是un_decorated,没有任何按钮
通过使用/更改另一个Look & Feel
,按钮数量(Top-Level Containers
)基本没有任何变化
