NAME

       Gtk2::Ex::FormFactory::DialogButtons - Standard Ok, Apply, Cancel Buttons

SYNOPSIS

         Gtk2::Ex::FormFactory::DialogButtons->new (
           clicked_hook_before => CODEREF,
           clicked_hook_after  => CODEREF,
           ...
           Gtk2::Ex::FormFactory::Container attributes
           Gtk2::Ex::FormFactory::Widget attributes
         );

DESCRIPTION

       This class implements a typical Ok, Apply, Cancel buttonbox in a Gtk2::Ex::FormFactory
       framework.

       If you associate an application object attribute the value needs to be a hash which may
       contain the keys 'ok', 'apply' and 'cancel' to control the activity of the correspondent
       buttons. Wheter inactive buttons should be render insensitive or invisible is controlled
       by the Gtk2::Ex::FormFactory::Widget attribute inactive.

       By default the following methods of the associated Gtk2::Ex::FormFactory instance are
       triggered:

         Ok        Gtk2::Ex::FormFactory->ok
         Cancel    Gtk2::Ex::FormFactory->cancel
         Apply     Gtk2::Ex::FormFactory->apply

NOTES

       No Cancel and Apply buttons are generated if the associated Gtk2::Ex::FormFactory has the
       sync attribute set. A synchronized FormFactory applies all changes immediately to the
       underlying objects, so there is no easy way of implementing the Apply and Cancel buttons.

       You can implement these by your own e.g. by registering a copy of your object to
       Gtk2::Ex::FormFactory::Context and hook into the button clicks using the
       clicked_hook_before attribute described beyond.

OBJECT HIERARCHY

         Gtk2::Ex::FormFactory::Widget
         +--- Gtk2::Ex::FormFactory::DialogButtons

ATTRIBUTES

       Attributes are handled through the common get_ATTR(), set_ATTR() style accessors, but they
       are mostly passed once to the object constructor and must not be altered after the
       associated FormFactory was built.

       clicked_hook_before = CODEREF("ok"|"apply"|"cancel")
           Use this callback to hook into the clicked signal handler of the buttons. Argument is
           the name of the button actually clicked ("ok", "apply" or "cancel"). If the callback
           returns TRUE, Gtk2::Ex::FormFactory's default handler for the button is called
           afterwards. Return FALSE to prevent calling the default handler.

       clicked_hook_after = CODEREF("ok"|"apply"|"cancel")
           This callback is called after the default handler. This is useful if you want to exit
           your program cleanly if your main dialog was closed. First Gtk2::Ex::FormFactory
           closes the dialog window for you, doing all necessary cleanup stuff. Afterward you
           simply call Gtk2->main_quit to exit the program.

           The callback's return value doesn't matter.
