I wrote the following .desktop file for my application named Qtag:
I copied it to /usr/share/applications, but I still cannot find my app in the menu (I use KDE Plasma 5 application launcher). When I try to open the file in Dolphin (the KDE file manager), it says that there is no Type=... entry in the file.
I use KDE Plasma 5. The executable and the icon are in the right places (qtag is in /usr/local/bin). Can anybody help me, please? Thank you.
