Question

我想知道是否可能：

使用最大化按钮制作一个jdialog（可以是模态）（是否可以自定义但最大化帧？）
或制作jframe（具有默认最大化按钮）模式？

有很多关于此的话题，但我找不到干净的解决方案。只有setEnabled（）等技巧

提前感谢大家！

Answer 1

AFAIK不可能，因为顶级容器来自Native OS，
然后鼠标双击到JFrame的工具栏调整大小容器以填充整个屏幕尺寸，第二次双击ćlick恢复lastz已知尺寸
JDialog
不响应来自Native OS的工具栏中的mouse_events，仅响应来自RootPane的

请看一下这个，你可以在你的问题中使用JDialog。

Java modal window with maximize button

带有最大化按钮的java模态框架
