Overview

FingerPaint

This utility lets you draw using your laptop's touchpad on Linux.

Pressing any key or clicking the touchpad will finish the drawing.

Your touchpad will not control the cursor while drawing, though external mice should still work.

It has support for both X11 (all desktop environments), and Wayland (just Gnome at the moment).

    Program hangs after closing GUI

    I noticed that the script doesn't end after closing the GUI using the keyboard. Without looking in detail I think this could be because keyboard events are not caught in this line, only using the mouse buttons works: https://github.com/Wazzaps/fingerpaint/blob/ff7090b4a5a0b999dc75ef687911e8c04299f3f4/fingerpaint/fingerpaint.py#L189-L191

  • Logitech K400 Plus trackpad not recognized

    Logitech K400 Plus trackpad not recognized

    I have a Logitech K400 Plus keyboard.

    It has a trackpad and left/right buttons built into in

    It interfaces to the computer via Logitech Unifying Receiver.

    Fingerpaint does not recognize it as a trackpad.

    Is there a way to inform Fingerpaint to use this trackpad?

  • Loosen dependencies

    Loosen dependencies

    Tightening the dependencies in your setup.py makes it hard for some packaging managers (pacman) to install the package. It is also not necessary to keep a specific version. I tested it using the newer version Pillow v8.3.1

    Also, (for me at least) there seems to be some issue with the Arch package python-pyudev giving the wrong version which also messes with this requirement.

    Feel free to just cherry-pick from https://github.com/jhossbach/fingerpaint/commit/9afe96d339f59353a4e7b4b22353e9ca331c2074.

    Hey there, it might be a good idea to create a version tag / release for the package. I can pick up from there and create an AUR package.

  • fingerpaint and fingerpaint-wayland AUR packages are the same?

    fingerpaint and fingerpaint-wayland AUR packages are the same?

    I checked PKGBUILDs of both the packages, and they both seem the same. Maybe I guess, earlier they were separate? If they are same now, as both wayland and xorg functionality is in same code, please consider making a request at AUR for deletion to avoid any confusion for some people who use both wayland and xorg on their systems (like me, i generally use wayland, but sometimes have to switch to xorg, when i am somewhere where people may use my laptop)

    Support for wlroots based compositors

    Besides GNOME and KDE, wlroots (wlr) is the only big thing on wayland right now on which a lot of compositors are based (like sway, hyprland, river). If wlroots is supported, all these compositors would get supported. Any plans for the support for wlr?

    Feature Request: "hover" cursor

    This is a great & fun project - thanks for making it. I saw it on OMG! Ubuntu.

    Would you consider implementing a mode where we only see a cursor at the point on the canvas that a touch corresponds to...and then it only draws while holding down a key?

    Thank you!
