GUI using C++

Question

How can you design GUI for a program using C++ ?

Answer 1

Yes, you can. But the standard C++ language and the Std library does not have direct support for graphics/GUI because this is often platform specific and left to 3rd parties.
Some C++ vendors do bundle their own libraries along with the std library, and these include graphics support. For example Microsoft C++ comes with MFC, Embarcadero C++ Builder comes with VCL, etc.
There are also 3rd party libraries available that support graphics/GUI like wxWidgets, Qt, Ultimate++ and others.

Answer 2

Hi @Jidesh, an OS does not need a GUI for apps at the kernel level - it is all command line / console stuff! Applications bundled with the OS that have GUIs are developed exactly like any other app with a GUI.
For Windows a lot of the legacy C++ apps used MFC for the GUI parts. On the Unix/Linux side, for example, the KDE GUI framework is developed using Qt.

Answer 3

Of course! Check out Qt!
