Raspberry Pi (Raspberry Pi) is a mini computer that is about the size of a credit card. It was originally designed for students to design a low-cost computer programming aids, because of its rich diversity people to apply it to a variety of projects.As a DIY King
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 us

Sometimes it is because the target platform does not allow or cannot install the required compiler, and some features of the compiler are required. Sometimes it is because the resources on the target platform are poor, it is impossible t
