<![CDATA[Kivy python cross-platform app framework?]]>Seems like the Kivy framework should be relatively easy to get working on UT, as it can be made to work with SDL2 it seems, or in the hopefully near future also with Wayland. It seems to work well on Android, iOS and Desktop and there was a previous attempt to get it working:
https://github.com/kivy/kivy/wiki/Ubuntu-Touch

https://kivy.org/

Way above my skills to get it working, but there is a nice XMPP client for it, which I would try to port once this framework is supported 🙂

Any one interested?

It appears that SDL2 isn't being detected / used, and thus no window is being created.

Also, do you happen to be using focal? I'm not sure if there are additional steps required for that.

using this command doesn't work ,

[CRITICAL ] [App ] Unable to get a Window, abort.
Exception ignored in: 'kivy.properties.dpi2px'

Edit1: ah, wait it's a PPA. Sorry was too quick to reply.

Edit2: No actually Clickable seems to support PPA as well, I guess? https://clickable-ut.dev/en/latest/clickable-json.html#dependencies-ppa

No repo yet - I'm just testing things for now. To test, I made / writable and then installed kivy from this ppa https://launchpad.net/~kivy-team/+archive/ubuntu/kivy?field.series_filter=xenial like so (SDL2 is also required, but should be installed automatically - not certain though as I had it preinstalled):

apt-get install kivy python3-pil

And then to run:

DESKTOP_FILE_HINT=unity8.desktop python3 <file.py>

It gives a Segmentation Fault sometimes, but rerunning usually fixes it.

Do you have a repository somewhere online?

Porting Kivy exposes some interesting potential, and it works for the most part out of the box - though some glitches will need to be fixed before it's stable.

What exactly is the disconnect here?
