If you use a blank QWidget, you won't have to do that setContentsMargin() workaround, right?

Yes, that's exactly what I'm doing. QFrame works fine for doing the same thing with the added benefit of easier styling around the edges. But if you *really want* I can switch it to a blank QWidget... it makes absolutely no difference though.

Fix various nitpicks

Hi ngraham:

• Switch to using QTreeView's methods for expand/collapse
• Filter threshold is 2 chars like KOpenWithDialog to avoid cluttering
• Reverted unnecessary changes (will do a different revision for refactor, error fixing, and clang-tidy style)
