How to Snap/Minimize/Maximize Window below cursor?

  • 772

The default Keyboard Shortcuts in Ubuntu to maximize a window (Super+Up) or snap it to the sides (Super+Left/Right) relates to the current active window.

While setting up mouse gestures using logiops, I found out that this is a weird behavior. I rather want to maximize/minimize/snap affect the window below my mouse pointer just like the scroll wheel does.

How to do this, e.g. using xdotool ?

  1. You can use xdotool to get the window at the current mouse location (getmouselocation) and then the commands windowminimize or windowactivate + key.

    I made a little script ~/bin/xdowindow (and made it executable using chmod +x):

    #!/bin/sh

[ "$1" = "Maximize" ] && set -- Up

eval $(xdotool getmouselocation --shell)

case $1 in
    Minimize)
        xdotool windowminimize "$WINDOW"
        ;;
    Left|Right|Up)
        xdotool windowactivate "$WINDOW" key --clearmodifiers super+$1
        ;;
    *)
        exit 1
        ;;
esac

    Set custom keyboard shortcuts:

    And then use them in logiops setup:

              {
            direction: "Right";
            mode: "OnRelease";
            action = {
              type: "Keypress";
              keys: [ "KEY_LEFTALT", "KEY_M" ]; // snap window to right
            }
          },

    Note:

    xdotool won't work together with wayland, maybe ydotool can be used then. I will test once I use wayland myself or someone else may jump in and translate the tool.
