98 This mixin provides a method C<displayable_name> for the calling module
99 which returns the a string depending on the settings of the
100 C<UserPreferences> (see also L<SL::Helper::UserPrefernces::DisplayableName>.
101 The value in the user preferences is scanned for a pattern like E<lt>%name%E<gt>, which
102 will be replaced by the value of C<$object-E<gt>name>.
106 The mixin must be configured on import giving a hash with the following keys
107 in the C<use> statement. This is stored in the specs an can be used
108 in a controller setting the preferences to display them.
114 The (translated) title of the object.
118 The C<options> are an array ref of hash refs with the keys C<name> and C<title>.
119 The C<name> is the method called to get the needed information from the object
120 for which the displayable name is configured. The C<title> can be used to
121 display a (translated) text in a controller setting the preferences.
