Qt is a cross-platform application and UI framework. Using Qt, you can write applications once and deploy them across desktop, mobile and embedded operating systems without rewriting the source code.

Qt Product Arch

Develop applications and user interfaces once, and deploy them across Windows, Mac, Linux/X11, embedded Linux, Windows CE and S60 (coming soon) without rewriting the source code.

Qt Visual Studio Integration

Qt is integrated with the Microsoft Visual Studio .NET and Eclipse integrated development environments. This means Qt programmers can use the IDE they are most comfortable with to do cross-platform development.

安装QT SDK 后,默认采用的是动态链接库的编译方式, 要生成静态的版本, 就需要自己重新进行编译.

设置 QMAKESPEC 为 win32-msvc2008 或 win32-msvc2005 的环境变量
设置 QTDIR 环境变量 如: C:\Qt\2009.05\qt
加入 C:\Qt\2009.05\qt\bin 到 PATH中
打开一个 Visual Studio command prompt 命令窗口
echo %QMAKESPEC%
configure.exe --help
C:\Qt\2009.05\qt\mkspecs\win32-msvc2008\qmake.conf
QMAKE_LFLAGS            = -static
configure -static -release -exceptions
nmake

常见错误

cannot open input file 'QtCored4.lib'// 是因为没有进行静态编译. 需先进行前面的操作.

QtUiToolsd.lib没编译出来

编译出的是类似 QtWebKitd4.lib, 而不是 QtWebKit4.lib

Code

Qt hello world

#include <QtGui>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel label("Hello, world!");
    label.show();
    return app.exec();
}

Compiling and executing

1. Create a folder named Hello
2. Copy paste the above program as Hello.cpp in folder Hello
3. At Hello folder run

 a. qmake -project
 b. qmake 
 c. make/gmake/nmake - as needed by OS and your compiler setups

4. Execute ./release/Hello (Or release\Hello.exe in Windows)
