全局应用菜单是否支持 Java 应用？

Question

我是 Java 应用程序（例如 Matlab 和 Maple）的重度用户。全局菜单会支持这些非常重要的包吗？

如果没有，是否有计划这样做？

Answer 1

通过安装 Jayatana，您可以为任何实现 JMenubar 的基于 Java 的应用程序进行全局菜单集成：

• 复制这个脚本
• 将其保存在您的桌面或主目录中。
• 打开终端，输入cd ~/
• 再次输入：bash path_to_the_newly_saved_script

• 按照说明进行操作（您需要互联网连接）。

  #!/bin/bash

  # Before executing this script make sure 
  # you're in your home directory `cd $HOME`
  #--------------------------------------------------
  
  # -------------------------------------NOTICE------------
  # APPLICABLE ONLY IN UBUNTU UNITY 
  # This script installs Jayatana for your JDKs 
  # It supposes you already have set your JAVA_HOME in ~/.bashrc
  # You will be prompted to choose which JDK to set as Default 
  # (choose the corresponding index).
  # In case you already installed jayatana and want to re-install, 
  # please uninstall then install again.

对于ECLIPSE来说，这是不同的。ECLIPSE 包在 libappmenu.so 库中被列入黑名单，因为它与全局菜单的集成在某种程度上被破坏了（菜单有时重复且无序）。EMACS23 也是如此（使用全局菜单时不会出现动态菜单）。因此，在开发人员提供全局修复之前，它们会被列入黑名单。
