Subject: Add 'activate' callback for the cylinder completion
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=bf33bf879faf08ef515be9c539e537a5d6df1f17;p=ext%2Fsubsurface.git

Add 'activate' callback for the cylinder completion

This makes us fill in the size/pressure data for a cylinder even if we
just type the name (rather than pick an entry from the list)
