Deepin: Shortcut for docking window to side/corner of screen
Following your last answer, and looking at the source code ; I found this using DBUS.
You can create a custom shortcut using the following line as command
qdbus com.deepin.wm /com/deepin/wm com.deepin.wm.TileActiveWindow 1
1
is for left, and 2
for right.
I haven't found a keyboard shortcut yet.
However, if you have a touchpad you swipe sideways with three fingers.
This way the focused window docks to a side of the screen.
If somebody finds a hotkey i would still be happy to know about it!
