>Second of all, Qt apps are extremely well integrated on Windows, OSX and Linux alike.

I've never seen a QT app that I couldn't immediately tell apart from a native OS X/Cocoa app -- with the exception of Skype, which still doesn't look 100% native, but at least looks like it has a decent skin.

isn't it possible that you've seen qt apps you couldn't tell apart and therefore didn't realise they were built with qt?

Nope, I follow UI toolkits pretty closely and always try to find a native app for a given task first and foremost. After that QT is the second best option, GTK somewhat worse, and Swing and other monstrocities to be avoided at all costs.

It's not subtle either, these things always stick like sore thumbs -- only exception are some that only use very basic widgets and delegate 90% of the work to native ones (like native file open dialogs etc).

But let's see, if you have any

From their page: "The Mac OS X interface is written in Objective-C and uses Growl notifications and dock badging to keep you informed".

They have different OS X (Cocoa/Obj-C), QT and even GTK implementation of the UI.
