checkVersion
fun checkVersion(requiredMajor: <Error class: unknown class>, requiredMinor: <Error class: unknown class>, requiredMicro: <Error class: unknown class>): String?
Checks that the GTK library in use is compatible with the given version.
Generally you would pass in the constants %GTK_MAJOR_VERSION, %GTK_MINOR_VERSION, %GTK_MICRO_VERSION as the three arguments to this function; that produces a check that the library in use is compatible with the version of GTK the application or module was compiled against.
Compatibility is defined by two things: first the version of the running library is newer than the version
Return
null if the GTK library is compatible with the given version, or a string describing the version mismatch. The returned string is owned by GTK and should not be modified or freed.
Parameters
requiredMajor
the required major version
requiredMinor
the required minor version
requiredMicro
the required micro version
