Java 鼠标悬停在区域上，以便进行二维扫描？

我在谷歌上找不到答案，但是对于

Slick2D

，是否有

鼠标悬停在区域上？谷歌只给了我
Java
的
mouseoverea
的结果。我只是想知道是否有
Slick2D
的
mouseoverea
，以及它的外观

这是我的代码：

我还在努力。。。但是这个类不需要
鼠标平均区域
，而
菜单
类需要


这就是我上面的代码。我只需要一个
mouseoverea
用于
Slick2D
。谷歌没有帮助。希望你能

另外，能否在
Slick2D
中设置
TextField
？我不知道我能不能。我知道在普通的
Java
中你可以，但是在
Slick2D
中你可以吗

如果有任何错误，请不要担心，我可以修复它们。

谢谢
