Wayland-Crosshair

A simple crosshair overlay for wayland using wlroots zwlr_layer_shell_v1. This code is an adaptation of wlroots examples/layer-shell.c and hello-wayland.

Requirements

Build: cmake pkgconf imagemagick wayland wayland-protocols wlroots

Run: wayland wlroots

Building

mkdir cmake-build
cd cmake-build
cmake ..
make

Installation

Copy wayland_crosshair and toggle-crosshair into the PATH, e.g. ~/bin.

On KDE, go to System Settings -> Shortcuts -> Add Command, enter toggle-crosshair and add a custom shortcut.

Note

I only tested this on KDE Plasma 5. For me, the crosshair is always in the center of the currently active screen. I don't know how it behaves on different window managers or scaling options.
