I'm running Trinity R14.0.4 on OpenSuSE Leap 42.2. Trinity Control Center reports that gtk-qt-engine is not installed, but YaST reports that it is. (See attachments.) This impairs use of some GTK-based applications. I'm not sure how to diagnose this further.

Your YaST search term is too limiting. What you need is both of:
trinity-gtk-qt-engine trinity-gtk3-tqt-engine
plus whatever deps.
Without YaST running, try this from terminal or Konsole:
zypper se -s gtk | grep qt
