Checking if QBool is available in Qt

Question

Qt4 had QBool that is not available in Qt5 ( http://qt-project.org/doc/qt-5.0/qtdoc/sourcebreaks.html ). Does anyone have a clue how to check if QBool is available in curret compilation?

CHecking Qt version should be enough. Is there possibility / way to check Qt's version like VC++'s _MSC_VER where we can check VC++ version and choose what to compile by pre-processors

Both Qt4 and Qt5 define QT_CORE_LIB (when QT += core set in project file)

Thanks

您可以使用QT_VERSION宏。
