如何在12.04和/或14.04 GTK3中启用助记符？

街上的一句话是“gtk-enable-mnemonics”自版本3.10以来已被弃用，我完全不确定如何让我的应用程序显示助记符。

只有按下alt键才会显示它们。

请看这里：

  • wxPython Button Shortcut Accelerator如何’＆spam’| 堆栈溢出

我已经尝试了本文中有关settings.ini的所有建议，将bool切换为相反的：

在使用GTK3的Ubuntu 14.04上“禁用”Nautilus 3.10.1的助记符：

  1. 如果尚不存在，请创建以下路径和文件。
    /home/YOURUSERNAME/.config/gtk-3.0/settings.ini
  2. 然后加：
    [Settings]
    gtk-enable-mnemonics = 0
  3. 然后注销并重新登录。

  • 设置：GTK + 3参考手册| GNOME开发人员中心

ps请注意，GTK文档说你应该有一个名为XDG_CONFIG_HOME的环境变量，但我没有。 我确实有一个现有的~/.config/gtk-3.0文件夹，它看起来默认情况下没有环境变量。

看起来GTK + -3在版本3.8之后（从版本3.10开始）丢失了“gtk-auto-mnemonics”设置。

3.14.4的以下补丁应该重新启用“gtk-auto-mnemonics”。 它可能也适用于其他GTK + -3版本，如3.16。 编译之后，你只需要这些文件（前两个是符号链接）： 

 libgtk-3.so -> libgtk-3.so.0.1400.4 libgtk-3.so.0 -> libgtk-3.so.0.1400.4 libgtk-3.so.0.1400.4

http://ftp.gnome.org/pub/gnome/sources/gtk+/3.14/gtk+-3.14.4.tar.xz

您可以轻松地开始使用编译的东西（如果需要，用lib替换lib64 ）： 

 LD_LIBRARY_PATH=/folder/where/you/installed/lib64 file-roller

不知道为什么，但看起来GTK +开发人员在删除提供这样有用function的代码方面变得非常棒…… !!!

如果任何GTK +开发人员读到这个：这些代码行是如何伤害任何人或为什么他们删除???

如果有人对原始提交感兴趣：

看起来GTK +人员当时有一个function删除运行：

我想我正在改变错误的主题。 哎呀。

遵循的步骤。

https://stackoverflow.com/a/24095212/2026508

更改自： gtk-auto-mnemonics = 0 <----已禁用

更改为： gtk-auto-mnemonics = 1 <----已启用

在GTK3中更改settings.ini： /usr/share/themes/CURRENT_THEME_NAME/gtk3.0/settings.ini

在GTK2中更改gtkrc： /usr/share/themes/CURRENT_THEME_NAME/gtk2.0/gtkrc

但请确保它是正确/当前主题。
