Subject: Add a completion for the cylinder type entry combo box
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;ds=sidebyside;h=0b4814a95d822ff99258f465cb123cd3f821eec2;p=ext%2Fsubsurface.git

Add a completion for the cylinder type entry combo box

This allows us to start typing the cylinder description and we'll get a
matching list that we can select.  This is similar to selecting one from
the model, and works in addition to the explicit selection.
