Ubuntu 18.04 上 Dash to Dock 中的动态垃圾桶图标

我想为我的 Dock 制作一个垃圾图标。Dash 到 Dock没有可以添加的垃圾图标，所以我打算做一个。我想要垃圾箱已满当有东西被添加到垃圾箱时，图标，我想要清空垃圾垃圾桶里没有东西时显示的图标。有人能告诉我怎么做吗？这是我的桌面文件：

[Desktop Entry]
Type=Application
Name=Trash
Comment=Trash
Icon=user-trash
Exec=nautilus trash://
Categories=Utility;
Actions=trash;

[Desktop Action trash]
Name=Empty Trash
Exec=/home/zacharygough/trash.sh -e

根据垃圾桶的状态自动更改 .desktop 文件的图标

在此处输入图片描述 在此处输入图片描述

Gio.Filemonitor用于监视状态（空或非空）的小脚本trash:///

如何使用

  1. 将以下脚本复制到一个空文件中，并命名watchout.py

  2. 替换以下行：

    # edit path to .desktop files and icon names below
self.fpath = "/home/jacob/Desktop/test.desktop"
self.iconempty = "user-trash"
self.iconfull = "user-trash-full"

    ...self.fpath如果你想要self.iconempty和self.iconfull

  3. 使用以下命令运行脚本：

    python3 /path/to/watchout.py

就是这样！

如果一切正常，请将相同的命令添加到启动应用程序。
