如何在 KDE 中以编程方式创建键盘快捷键？

发布于 2024-09-09 10:45:57 字数 594 浏览 3 评论 0原文

我可以使用控制中心界面的输入操作部分为 Ctrl-F1 和 Ctrl-F2 创建键盘快捷键，使它们启动脚本。目前感兴趣的平台是 CentOS 5 上的 KDE 3.5，但 4.x 也是直接利益较少。

然而，我需要的是从 shell 脚本创建相同的快捷方式，在安装 RPM 后运行：此 RPM 创建一个用户，然后完全预配置其 KDE 环境。到目前为止，我已经能够执行类似的操作

cat > kdesktoprc <<- EOM
[Desktop0]
WallpaperMode=NoWallpaper
EOM

，然后在第一次登录时，KDE 设置将从那里正常启动。我想我想做的是预置这个特定帐户，但我不想干扰任何其他当前或未来的帐户同一个主机。

不幸的是，我无法使用输入进行相同的工作 Actions，其配置稍微复杂一些。尝试之前为了进一步解决这个问题，我决定询问是否有更好的方法。

换句话说，是否有一个命令来创建键盘快捷键（我没有我认为我可以使用 DCOP，因为当时 KDE 不会运行）？

我浏览了 kconf_update 机制的提示，但无法确定它是否适合我的用例：是否有可用的参考？

先感谢您，

I am able to create keyboard shortcuts for Ctrl-F1 and Ctrl-F2, making them launch a script, using the Control Center interface, Input Actions section. The platform of interest is KDE 3.5 on CentOS 5 at present, but 4.x is also of
less immediate interest.

What I need, however, is to create the same shortcuts from a shell script, run after installation of an RPM: this RPM creates a user and then preconfigures its KDE environment completely. So far, I've been able to do stuff like

cat > kdesktoprc <<- EOM
[Desktop0]
WallpaperMode=NoWallpaper
EOM

and then upon first login the KDE setup would pick up from there just fine.
I guess what I am trying to do is preseeding this specific account, but I
don't want to interfere with any other present or future account on the
same host.

Unfortunately, I have not been able to make the same work with Input
Actions, whose configuration is somewhat more involved. Before attempting
to unravel it further, I decided to ask if there was a better way.

In other words, is there a command to create a keyboard shortcut (I don't
think I can use DCOP, because KDE would not be running at the time) ?

I skimmed hints to the kconf_update mechanism, but was unable to ascertain if it was appropriate for my use case: is there a reference available ?

Thank you in advance,

我找到了一种似乎有效的方法。首先，我创建一个 .khotkeys 文件，
将其命名为 zzz.khotkeys，并将其存储在 /usr/hsare/apps/khotkeys 下。一个好的
其起点是 printscreen.khotkeys 文件。

此 .khotkeys 文件有两个部分，一个包含热键定义的 [Data] 部分，以及一个 [Main] 部分，其中我们拥有其他键，

Id=zzz

用于记住哪些键定义已导入。

要使 zzz.khotkeys 中的定义生效，您可以使用它

/usr/lib/kconf_update_bin/khotkeys_update --id zzz

，它似乎调用与中的“导入”按钮等效的功能
“输入操作”用户界面。

这一步在我的场景中遇到了许多障碍，即运行所有
RPM 安装的 %post 脚本中的上述内容。

首先，如果 khotkeys_update 无法联系 X 服务器，它就会失败；在
表面上这似乎很愚蠢，因为它只需要执行文本整理，
但这可以通过将其调用放在 .kde/Autostart 中的 .desktop 文件中来解决。

其次，khotkeys_update 看起来并不完全像一个已发布的接口
随着时间的推移可以信赖；因为这是针对 CentOS/KDE 3.5 的
在一个预计不会发生任何变化的环境中，我很荣幸能够
认为这是一个小问题。如果有已发布的（shell）接口
执行导入，我找不到它（我没有调查DCOP）。

最后，同样的脚本直接定制了其他配置
.kde/share/config 下的文件还在 .kde/Autostart 下添加了一个名为
zzz-keys.desktop 看起来像是

[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=ZZZ Hotkeys
Comment=Ensure ZZZ keyboard shortctus are available
Exec=/usr/lib/kconf_update_bin/khotkeys_update --id zzz

第一次添加热键（它们最终位于 khotkeysrc 内）
并且在后续调用中被跳过，因为 khotkeysrc 包含一个密钥
名称 AlreadyInstalled 也更新为包含“zzz”等
后续运行 khotkeys_update 会找到它并且不会添加重复项。

I found an approach which appears to work. First, I create a .khotkeys file,
call it zzz.khotkeys, and store it under /usr/hsare/apps/khotkeys. A good
starting point for that is the printscreen.khotkeys file.

This .khotkeys file has two sections, a [Data] section with the hotkey definition(s), and a [Main] section where among other keys we have

Id=zzz

which is used to remember which key definitions have been already imported.

To put the definitions in zzz.khotkeys into effect, you could use this

/usr/lib/kconf_update_bin/khotkeys_update --id zzz

which seems to invoke functionality equivalent to the "Import" button in
the "Input Actions" user interface.

This step incurs a number of obstacles in my scenario, which is running all
of the abovce in the %post script of an RPM install.

First, khotkeys_update fails if it cannot contact an X server; on the
surface this seems silly, as it should only need to perform text wrangling,
but this can be addressed by placing its invocation inside a .desktop file in .kde/Autostart.

Second, khotkeys_update does not exactly look like a published interface
which can be relied upon over time; since this is for CentOS/KDE 3.5 in
a context where little evolution is expected, I enjoy the privilege to
consider this a minor issue. If there is a published (shell) interface to
perform the import, I could not find it (I did not investigate DCOP).

In the end, the same script which directly customized other configuration
files under .kde/share/config also adds under .kde/Autostart a file named
zzz-keys.desktop which looks like

[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=ZZZ Hotkeys
Comment=Ensure ZZZ keyboard shortctus are available
Exec=/usr/lib/kconf_update_bin/khotkeys_update --id zzz

which gets the hotkeys added the first time (they end up inside khotkeysrc)
and is skipped on subsequent invocations, because khotkeysrc includes a key
name AlreadyInstalled which is also updated to include "zzz", so on
subsequent runs khotkeys_update finds it and does not add duplicates.
