checkVersion

Checks that the GTK library in use is compatible with the given version.

Generally you would pass in the constants [gtk.types.MAJOR_VERSION], [gtk.types.MINOR_VERSION], [gtk.types.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 required_major.required_minor.required_micro. Second the running library must be binary compatible with the version required_major.required_minor.required_micro (same major version.)

This function is primarily for GTK modules; the module can call this function to check that it wasn’t loaded into an incompatible version of GTK. However, such a check isn’t completely reliable, since the module may be linked against an old version of GTK and calling the old version of [gtk.global.checkVersion], but still get loaded into an application using a newer version of GTK.
