Cannot compile (missing signal cfg_keepOneEmptyDesktopChanged in class VirtualDesktopBar.h)

[Tardog]

I'm trying to install the widget on Ubuntu 18.04 using the latest master (I tried the latest release as well, with identical results). While following the installation instructions, I consistently run into the following error during make:

[ 16%] Built target org.kde.plasma.virtualdesktopbar-plasmoids-metadata-json
[ 33%] Automatic MOC for target virtualdesktopbarplugin

An idea what's going on there?

It seems older Qt frameworks are more strict about Q_PROPERTY and NOTIFY can only accept signals. For some reason, I can't annotate the notifying methods as signals, due to other build errors. Instead, I've replaced NOTIFY with something else. Please try the latest version.

No errors during compilation/installation after the latest changes. The widget itself works like a charm. Looks good to me! :+1: Thank you for your fast response.
