To where -- I'm told -- Windows developers expect it to go: the debug output 
(Qt uses the Win32 call OutputDebugStringW), to the detriment of many a 
helpgiver on IRC who often faces the dialog:

 <user> My function isnt called, I put a qDebug there and nothing!!!11one
 <helpgiver> Are you using Windows?

If you use Qt Creator or Visual Studio, they will capture the output and show 
it for you. If you don't use either of those tools, you should run 
dbgview.exe[1].

The advantage is that you do not need to set the application to console mode, 
since the output is not in stderr.

By the way, another must-have tool for Windows developers is depends.exe[2], 
the replacement for ldd and otool -L, the usual answer to "My application 
won't load on my friend's system" problem.
