Mopidy Discourse

Chromium on-screen keyboard in Iris search field

Hi all,

this is my first post on this Discourse board, so please don’t mind if I am struggling with bringing all the info together. Thanks for this brilliant piece of software. My question below is mainly focused on the Iris-Extension, so if it’s better to continue the discussion on the Github repo, then please feel free to tell me.

I built a music player for my son based on a 7" touchscreen running Chromium in kiosk mode and based on Mopidy and Iris. As source, I am using Spotify (i.e. the Mopidy-Spotify extension). Currently, the system has been set up using the “RPi-Jukebox-RFID” package but I had installed “bare” Mopidy and Iris beforehand with the same result.

Owing to the touchscreen, I figured it would a good idea to use an on-screen keyboard (OSK) installed as Chromium extension (the ones from Chromium do neatly integrate, automatically pop-up, etc.). However, when I try to search titles using the Search field in Iris, the Enter button seems not to work correctly.

After pushing the enter button on the OSK, the URL changes to …/iris/search/all/ and the search stays empty. Using a USB keyboard, a web client from another device (mobile, laptop) and even the “normal” OSKs like Matchbox, Florence work like a charm. In fact, if I use the USB keyboard to enter one character of the search string and then finalize the search using the OSK “enter” button, then the search also works without any problems.

I tried to log Mopidy, but didn’t see any actions in it related to the search. I then tried to activate Test Mode in Iris and checked the Chromium console. I would love to post the results here, but I am struggling to find chromium debug file (started Chromium using --enable-logging, but the debug-log file is not in the .config folder for some reason, will try to hook up the RPi to a proper setup with screen and keyboard later).

Cheers and many thanks to all the people keeping this nice project up!

/iris/search/all/ is the URL you get if you just press enter without typing anything in the search box, so it sounds like it isn’t recognising the input into that box for some reason.
