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

Hi, when I try to run fingerpaint, I encounter the following issue:

Traceback (most recent call last):
  File "/home/<user>/.local/bin/fingerpaint", line 8, in <module>

Touchpad used is SYNA2393:00 06CB:7A13, OS is Ubuntu 20.04 with GNOME 3.36.8.

When I try to run fingerpaint, I get this error:

Using touchpad: XXXXXXX Touchpad
Traceback (most recent call last):
  File "/home/XXX/.local/bin/fingerpaint", line 8, in <module>

I am running Fedora 34, with GNOME DE. (I changed some personal information for XXX).

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?

I am wondering whether Wayland is supported now, is xinput still needed? There was an issue on the AUR: https://aur.archlinux.org/packages/fingerpaint-wayland

https://github.com/Wazzaps/fingerpaint/blob/12b865681dbe4b5602bc052e9f6dd7d515554952/fingerpaint/fingerpaint.py#L298-L305

I get this error when I tap on the touchpad:

$ fingerpaint -o test.png Using touchpad: SYNA3082:00 06CB:8265 Touchpad Traceback (most recent call last): File "$HOME/.local/bin/fingerpaint", line 8, in sys.exit(cli()) File "$HOME/.local/lib/python3.6/site-packages/fingerpaint/fingerpaint.py", line 288, in cli main(args) File "$HOME/.local/lib/python3.6/site-packages/fingerpaint/fingerpaint.py", line 207, in main make_ui(handler_loop(), scaled, devname, args) File "$HOME/.local/lib/python3.6/site-packages/fingerpaint/fingerpaint.py", line 89, in make_ui width=int(args.line_thickness * aa_factor), joint='curve', fill=(0, 0, 0) TypeError: line() got an unexpected keyword argument 'joint'

right now fingerpaint opens up in small windows which is sort of limited in visual sense when we want to doodle. It would be nice to have a maximize window option

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.

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)

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?

For an easy installation, clicking Install at Snap Store in Ubuntu, which is the first Linux distro for many new users now coming to Linux. Solus, KDE Neon, Manjaro, MakuluLinux, Ubuntu MATE, Zorin OS etc. support snapd by default too.

Request was put up originally to here: https://forum.snapcraft.io/t/fingerpaint-draw-with-touchpad-or-sign-a-signature-easily-only-non-beginner-friendly-installation-available/31234

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!

I'm using Manjaro Gnome with Wayland and installed the fingerpaint-wayland aur.

When I use the following command: fingerpaint - o test.png I get the following output:

Using touchpad: SynPS/2 Synaptics TouchPad Unexpected touchpad state: "", are you using Gnome?
