NAME

       Gtk2::version -	Library Version Information

SYNOPSIS

	 use Gtk2 '1.023';  # require at least version 1.023 of the bindings

	 if ($Gtk2::VERSION >= 1.040 and Gtk2->CHECK_VERSION (2, 4, 0)) {
	    # the GtkFileChooser, new in gtk+ 2.4.0 and first supported in
	    # Gtk2-Perl at 1.040, is available
	 } else {
	    # GtkFileChooser is not available, fall back to GtkFileSelection
	 }

DESCRIPTION

       Since the Gtk2 Perl module is a bridge to an external library with its own versions and API revisions, we have three different versions
       available for inspection.  Which one you need to use at which time depends entirely on the situation.  Gtk2 uses the same scheme as Glib
       and the underlying gtk+ C library; that is, the standard $Gtk2::VERSION for the version of the bindings, all-caps
       (MAJOR|MINOR|MICRO)_VERSION functions for the bound version, and lower-case (major|minor|micro)_version functions for the runtime version.
       See Glib::version and http://developer.gnome.org/doc/API/2.0/gtk/gtk-Feature-Test-Macros.html
       <http://developer.gnome.org/doc/API/2.0/gtk/gtk-Feature-Test-Macros.html> for more information.

       Note also that gtk_check_version() and GTK_CHECK_VERSION() have different semantics in C, and we have preserved those faithfully.

METHODS

   boolean = Gtk2->CHECK_VERSION ($required_major, $required_minor, $required_micro)
       o   $required_major (integer)

       o   $required_minor (integer)

       o   $required_micro (integer)

       Provides a mechanism for checking the version information that Gtk2 was compiled against. Essentially equvilent to the macro
       GTK_CHECK_VERSION. In most cases this function should be used rather than check_version ().

   (MAJOR, MINOR, MICRO) = Gtk2->GET_VERSION_INFO
       Shorthand to fetch as a list the gtk+ version for which Gtk2 was compiled.  See "Gtk2::MAJOR_VERSION", etc.

   integer = Gtk2::MAJOR_VERSION
       The major version of the gtk+ library against which Gtk2 was compiled.  Equivalent to gtk+'s GTK_MAJOR_VERSION.

   integer = Gtk2::MICRO_VERSION
       The micro version of the gtk+ library against which Gtk2 was compiled.  Equivalent to gtk+'s GTK_MICRO_VERSION.

   integer = Gtk2::MINOR_VERSION
       The minor version of the gtk+ library against which Gtk2 was compiled.  Equivalent to gtk+'s GTK_MINOR_VERSION.

   string = Gtk2->check_version ($required_major, $required_minor, $required_micro)
       o   $required_major (integer)

       o   $required_minor (integer)

       o   $required_micro (integer)

       Returns undef if the version of gtk+ currently in use is compatible with the given version, otherwise returns a string describing the
       mismatch.  Note that this is not the same logic as "Gtk2::CHECK_VERSION".  This check is not terribly reliable, and should not be used to
       test for availability of widgets or functions in the Gtk2 module --- use "Gtk2::CHECK_VERSION" for that.  See Glib::version for a more
       detailed description of when you'd want to do a runtime-version test.

   integer = Gtk2::major_version
       The major version of the gtk+ library current in use at runtime.  Equivalent to gtk+'s global variable gtk_major_version.

   integer = Gtk2::micro_version
       The micro version of the gtk+ library current in use at runtime.  Equivalent to gtk+'s global variable gtk_micro_version.

   integer = Gtk2::minor_version
       The minor version of the gtk+ library current in use at runtime.  Equivalent to gtk+'s global variable gtk_minor_version.

   (major, minor, micro) = Gtk2->get_version_info
       Shorthand to fetch as a list the gtk+ version against which Gtk2 is linked.  See "Gtk2::major_version", etc.
