创建一个舍入的JFrame / ContentPane

问题描述

我正在创建一个带圆角的登录窗口。一切都很好，请参阅图片，但我遇到了使JFrame / ContentPane透明化的挑战。每个角落都有白色区域（箭头所示），我似乎无法删除，因为我无法为JFrame或ContentPane将opague设置为false。

I'm creating a login window with rounded corners in java. Everything is OK, see pic, but i'm having challenges making the JFrame / ContentPane transparent. There are white areas at each corner (shown by the arrows) that i seem not to be able to remove since i can't set opague to false for the JFrame or ContentPane.

如何删除这些白色区域的任何想法

推荐答案

对你没什么帮助，但Java7将支持透明和形状的窗口：。这些已在Java 6u10中提供，但不是公开的，即，您需要使用不受支持的com.sun ...类，以后可能会更改并破坏您的程序。

Not much help to you but Java7 will support transparent and shaped windows: More info here. These are available already in Java 6u10 but not publicly, ie, you need to use an unsupported com.sun... class that might change in future and break your program.
