通过边缘绑定显示启动器

当鼠标进入“触发”区域时显示启动器

当鼠标指针进入某个区域（图像中的激活区域）时，下面的脚本会激活（自动隐藏）启动器。

由于必须向目标启动器图标画一条直线并不方便，启动器激活后，我在屏幕左侧（右）创建了一个 200px 的区域，您可以在其中自由移动无需再次隐藏发射器（移动区域）。

如何使用

1. 该脚本用于xdotool获取鼠标位置：

   sudo apt-get install xdotool
   

2. 将脚本复制到一个空文件中，另存为trigger_launcher.py

3. 在脚本的头部部分，我设置了适合您的屏幕组合和顶部对齐的值。但是，如果您将脚本与其他屏幕（尺寸）一起使用，或者您想更改（触发）边距，则可以在脚本的头部进行更改：

   # the script assumes the two screens are top-alligned (!)
   
   #-- set the area to trigger the launcher (from left bottom of second screen) below:
   vert_marge = 50
   hor_marge = 200
   #-- set the width of the left screen below:
   width_screen1 = 1680
   #-- set the height of the right screen below:
   height_screen2 = 900
   #---
   

4. 使用以下命令测试脚本：

   python3 /path/to/trigger_launcher.py
   

5. 如果一切正常，将其添加到您的启动应用程序：Dash > Startup Applications > Add。添加命令：

   /bin/bash -c "sleep 15&&python3 /path/to/trigger_launcher.py"

下面的版本有 3 秒的时间中断，而不是“移动区域”，正如您在评论中提到的那样。
