I need to use Qt for a GUI on a "legacy" .NET application used managed C++. The .NET backend is used for system level calls. I'll be using VS2005 There's a lot of good information at this page <http://doc.trolltech.com/4.1/activeqt-dotnet.html> at Trolltech. But it doesn't cover everything. My main concerns center around using QApplication, QMainWindow, and .NET events. Has anyone used Qt with .NET and "managed" C++? Any tips?
