KRunner will do this for you, actually. If you type “calc”, and the plasmoid
runner is installed, you’ll get a match offering to run the plasmoid in a
window. Well, it doesn’t actually *say* that, since that’s jargon, but that’s
what the match does.
For plasmoids suited to being run as an app they should also install a
.desktop file with this command in it so that it is completely transparent to
All of the above occurs in Plasma Active, so we know it works well from a

We did it for Plasma Active because we found ourselves needing it there. I
know it was blogged about by both myself and Marco (perhaps others?), but
blogs are indeed easily missed. It should become more visible with Qt5 where
(as you note below) we can realistically start creating full desktop apps with
QML, making the lines are blurry enough on Desktop to start using it there. In
Active, the lines are already blurry / non-existent ... but more people use
Desktop still ;)

Agreed; I think it really starts to make sense with the advent of the QtQuick
