In Visual Studio, build the test project
in [MotionBuilder]\OpenRealitySDK\samples\tools\toolqttest.
Start MotionBuilder, and choose from
the Open Reality menu FBQtTest. The Open Reality menu is not present
by default; it is added when MotionBuilder detects the presence
of plugins in [MotionBuilder]\bin\[win32|x64]\plugins.
Open Reality > FBQtTest launches a
tool containing a native Qt widget created with QtAssitant, and
a normal FBButton.
