基本上我正在做的是创建一个充当启动器的swing应用程序。它所做的就是为用户提供3种选择,可以选择打开新的Java应用程序。 3个不同的java应用程序都有不同的主题,其中一个根本没有主题。我试图这样做,所以当我选择一个选项时,我的启动器应用程序不会将它自己重新绘制为新程序。我希望发射器能够保持其主题。
我可能没有正确使用EventQueue,但我不确定使用哪一个。

这个基于Swing的Launcher
使用ProcessBuilder
在单独的JVM中运行程序。您可以通过使用非默认Look & Feel运行应用程序来评估其是否适合您的应用程序。请注意左侧的MetalLookAndFeel
和下图中右侧的AquaLookAndFeel
。
$ java -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel \
-cp build/classes gui.Launcher
