#
# A base class for creating DHTML confirmation types.
#
# The real work is done by the onclick_function and onclick_handler methods. In
# general it should only be required to override the default onclick_handler
# method and provide the specific Javascript required to invoke the DHTML confirm
# dialog of your choice.
#
# It is up to this dialog, if the user confirms the intended action, to invoke
# the function window.gFireModalLink() to trigger the intended action of the link.
# For example, using the Modalbox library, you would use something like:
#
# Modalbox.hide( {
# afterHide: function() {
# window.gFireModalLink();
# } } );
#
# By default the only action recognized is :value which is used to add a
# dhtml_confirm attribute to the link <a> tag. This value is detected by the
# ActiveScaffold link and triggers the DHTML confirmation logic.
#
