Version Information Variables and functions to check the GTK+ version GTK+ provides version information, primarily useful in configure checks for builds that have a configure script. Applications will not typically use the features described here. @void: @Returns: @void: @Returns: @void: @Returns: @void: @Returns: @void: @Returns: @required_major: @required_minor: @required_micro: @Returns: Like #gtk_major_version, but from the headers used at application compile time, rather than from the library linked against at application run time. Like #gtk_minor_version, but from the headers used at application compile time, rather than from the library linked against at application run time. Like #gtk_micro_version, but from the headers used at application compile time, rather than from the library linked against at application run time. Like #gtk_binary_age, but from the headers used at application compile time, rather than from the library linked against at application run time. Like #gtk_interface_age, but from the headers used at application compile time, rather than from the library linked against at application run time. Returns %TRUE if the version of the GTK+ header files is the same as or newer than the passed-in version. @major: major version (e.g. 1 for version 1.2.5) @minor: minor version (e.g. 2 for version 1.2.5) @micro: micro version (e.g. 5 for version 1.2.5)
