get_major_version

function get_major_version():Number {
    // Gjs wrapper for gtk_get_major_version()
}

Returns the major version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 3.)

This function is in the library, so it represents the GTK+ library your code is running against. Contrast with the #GTK_MAJOR_VERSION macro, which represents the major version of the GTK+ headers you have included when compiling your code.

Since 3.0
