developers need to build an art-level graphical user interface. QT is easy to scale and allows for real component programming. Basically, Qt is the same type of thing as the MOTIF,OPENWIN,GTK on the X Window and the Mfc,owl,vcl,atl on the Windows platform.To put it simply, QT can write programs that are easily ported to other platforms, basically recompiling the program.install qt on Raspberry PiInstall using the following commandsudo apt-get install
