如何在12.04和/或14.04 GTK3中启用助记符？

8

在大街上说的是，自3.10版以来，“ gtk-enable-mnemonics”已被弃用，我根本不确定如何使我的应用程序显示助记符。

仅当我按键时，它们才会显示alt。

请在这里查看：

我已经尝试了本文中有关settings.ini的所有建议，将布尔值切换为相反的值：

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

  1. 创建以下路径和文件（如果尚不存在）。
    /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。

ps请注意，GTK文档说您应该有一个名为的环境变量，XDG_CONFIG_HOME但我没有。我确实有一个现有~/.config/gtk-3.0文件夹，并且看起来默认情况下它在其中查找，而没有环境变量。

我真的对这个答案感到困惑，因为这个问题似乎在询问如何启用始终显示助记符的功能，但是此答案涉及禁用助记符的问题。

好点，我不知道为什么要把这个作为答案发布。

在3.8版（从3.10版开始）之后，GTK + -3似乎丢失了“ gtk-auto-mnemonics”设置。

用于3.14.4的以下修补程序应重新启用“ gtk-auto-mnemonics”。它可能还将与其他GTK + -3版本（如3.16）一起使用。编译后，您只需要这些文件（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

您可以通过以下方式轻松开始使用编译后的内容（如有必要，请替换lib64为lib）：

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

不知道为什么，但是看起来GTK +开发人员在删除提供像这样有用的功能的代码方面真的很棒。

如果有任何GTK +开发人员阅读以下内容：这些代码行如何对任何人造成伤害或为什么将其删除？

如果有人对原始提交感兴趣：

看起来GTK +当时有功能删除功能：

我想我改变了错误的主题。哎呀。

遵循步骤。

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

更改自：gtk-auto-mnemonics = 0 <----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

但是请确保它是正确/当前的主题。
