QT編譯
打開 “Visual Studio 命令提示”.在“Visual Studio 命令提示”下定位到程序目錄運行：configure -platform win32-msvc2008 -nomake demos -nomake examples -no-opengl -no-qt3support.
運行 “nmake”命令.
使用了Q_OBJECT宏之後在編譯的時候會遇到下面的錯誤：
--------------------Configuration: testqt - Win32 Debug--------------------

解決方法，使用moc命令自動生成moc_*.cpp文件，具體操作入下圖：
