Use mingw, msys, and QT to write the interface in windows.

If you want to write interfaces in windows, there are many c ++ interface libraries, such as the built-in MFC Library in VC ++. However, if you use these libraries ProgramPorting to other platforms is a very painful process. QT is a very good C ++ interface library, which is cross-platform, well-structured and easy to use. Now we will briefly introduce how to use mingw and msys to compile QT programs in windows.
1) install mingw and msys
2) install QT
Download the corresponding installation file and install it all the way. After installing QT, add the QT path to the environment variables of windows. Here is:
C: \ QT \ 4.4.3 \ bin
In this way, you can use the QT command at any location in cmd.
3) set the hello World Section CodeCopy it in. The help files of QT include:
# Include <qapplication>
# Include <qpushbutton>
Int main (INT argc, char * argv [])
{
Qapplication app (argc, argv );
Qpushbutton Hello ("Hello world !");
Hello. Show ();
Return app.exe C ();
}
To facilitate compilation, you can save the code file to a single folder.
4) use qmake to create a project
Qmake-Project
Qmake
Run the preceding two commands in the target code folder. The first command generates a qthello. pro file, the second command qmake will be based on this. pro file to create makefile files related to the platform.
5) run the make command in msys for compilation.
If the compilation succeeds, the two sub-folders debug and release will be created under this folder, which contains the executable files generated after you make.
