title: How to make applications in QtCreator use KDE oxygen theme?
body: <p>I'm aware that the reason it's not already doing this is because KDE uses Qt 4. Unfortunately, I'm using Archlinux, and when I install the KDE window manager, it automatically installs Qt 5. If anyone could tell me how to use Qt 4 on Archlinux, or any other workarounds, I would really appreciate it.</p>
  
  <p>EDIT: I'm talking about applications compiled in qtcreator, I couldn't care less about how qtcreator itself looks.</p>
