QtInfo

QtInfo has two main goals:

Display basic Qt-related information in an easy-to-report-to-developer way. It is NOT a hardware-info tool, nor does it try to display information that is not available via Qt APIs
Demonstrate how to dynamically detect available functionality to address a fragmented deployment base (optimize for best available featureset instead of lowest common denominator). It's not about having an elegant #WorksForMe, it's about #WhatEverItTakes to run on as many Qt platforms as possible.

Platforms known to run or ran QtInfo in some shape or form (see screenshots below), in reverse order of appearance:

(Windows Phone - Work in progress, waiting for Qt 5.3)
Android
SailfishOS
BlackberryOS 10
MeeGo (meego.com MeeGo)
MeeGo Harmattan 1.2
Symbian^3
MacOS X
Windows
Maemo 5
Linux

Qt 4.5 needs to be installed for the application to work. For a declarative UI, Qt 4.7 or better is needed. QtInfo has (preliminary) Qt5 support, but unlike the rest of the libraries, it is not runtime-detected yet (the plan is to have dual binaries eventually).

Currently displays (all the info is obtained at run-time, not compile-time):

Mobility version
Installed Qt modules
Qt build and licensing info
