Usage is as follows: \code #include "jkqtmathtext/jkqtmathtext_imexport.h" class JKQTMATHTEXT_LIB_EXPORT exportedClassName { ... }; JKQTMATHTEXT_LIB_EXPORT void exportedFunctionName(); \endcode These macros append the appropriate \c __declspec(dllexport) and \c __declspec(dllimport) to the function/class body and thus tell windows compilers to export these sysmbols from the shared library, or import them from a shared library. Note that these attributes are only necessary on windows systems! These macros are controlled by two other macros: - \c JKQTMATHTEXT_LIB_IN_DLL declares that the application should link against a shared version of JKQTMathText, i.e. \c JKQTMathTextSharedLib_XYZ . This needs to be defined while compiling the library and while compiling any application linking against \c JKQTMathTextSharedLib_XYZ. - \c JKQTMATHTEXT_LIB_EXPORT_LIBRARY is only defined while compiling JKQTMathText into \c JKQTMathTextSharedLib_XYZ and ensures thet the symbols are exported. If it is not defined (e.g. while compiling an application), the symbols are imported . */ /*! \def JKQTMATHTEXT_LIB_IN_DLL \ingroup jkqtmathtext \brief declares that the application should link against a shared version of JKQTMathText, i.e. \c JKQTMathTextSharedLib_XYZ .
