当我的应用程序打开一个新的 Java 程序时，如何防止我的应用程序使用新主题重新绘制自己? [英] When my app opens a new java program, how do I prevent my app from repainting itself with a new theme?
本文介绍了当我的应用程序打开一个新的 Java 程序时，如何防止我的应用程序使用新主题重新绘制自己?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
基本上，我正在做的是创建一个用作启动器的 Swing 应用程序.它所做的只是为用户提供 3 个选项，他们可以从中选择打开一个新的 Java 应用程序.3 个不同的java 应用程序都有不同的主题，一个根本没有主题.我正在尝试获取它，因此当我选择一个选项时，我的启动器应用程序不会将其重新绘制为新程序的内容.我希望启动器保持其主题.
Basically what I'm doing is creating a swing application that acts as a launcher. All it does is gives the user 3 options they can choose from to open a new java application. The 3 different java applications all have different themes, and one doesn't have a theme at all. I'm trying to get it so when I select an option, my launcher app doesn't repaint it self to what the new program is. I want the launcher to maintain its theme.
我可能没有正确使用 EventQueue，但我不确定该使用哪一个.
I'm probably not using EventQueue right but I'm not sure which one to use.

This is a class that creates the new application the user selects
package wind;

this.mode = mode;

GUI,
NOGUI;
}
public void initClient() {
switch(mode) {
case APPLICATION:

推荐答案
This Swing based Launcher 使用 ProcessBuilder 在单独的 JVM 中运行程序.您可以通过使用非默认的 看&感觉.注意下图中左侧的 MetalLookAndFeel 和右侧的 AquaLookAndFeel.
This Swing based Launcher uses ProcessBuilder to run programs in a separate JVM. You can assess its suitability for your application by running it with a non-default Look & Feel. Note MetalLookAndFeel on the left and AquaLookAndFeel on the right in the illustration below.
$ java -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel \
-cp build/classes gui.Launcher
