Running OpenBoard in a window

These days I'm forced again to do lessons from remote. My school asked me to refer to Google Meet for the videoconferences and one thing I disliked was the Jam interactive whiteboard, which is completely inadequate for scientific subjects. On the other hand OpenBoard, my favourite board tool that I successfully use with Zoom, seemed not to be recognized as an application to be shared, because it runs fullscreen.

After some googleing I found a patch from this guy (I big thank for his work!) which forces OpenBoard to run in a window, but at the cost of passing a variable at compilation time. I modified the logic of that patch so that a user can set how OpenBoard will run just modifying a configuration option. The "run in a window" feature is disabled by default, so it will not bother those teachers who are already familiar with the interface, but it can be easily switched on by advanced users.

To get OpenBoard running in a window just switch this option to true in the /opt/openboard/etc/OpenBoard.config file


Each user can do the same overriding this setting in his/her personal ~/.local/share/OpenBoard/OpenBoardUser.config file.

Known issues

As someone else already reported here, when sharing the OpenBoard window with zoom, its bottom is partially unavailable for about 50px. You can always put the toolbar at the top, but it's clearly a malfunction. I've only encountered this problem the very first time I runned zoom with the new feature and it doesn't seem like something well reproducible.
