=head1 WIDGET METHODS

=over 4

=item I<$tree>-E<gt>B<Fill>(?I<-nocache =E<gt> 1>?, ?I<-forked =E<gt> 0|1>?, ?I<-fillcb =E<gt> ...>?)

Find Pod modules and fill the tree widget. If I<-nocache> is
specified, then no cache will be used for loading.

A cache of Pod modules is written unless the B<-usecache>
configuration option of the widget is set to false.

If C<-forked> is specified, then searching for Pods is done in the
background, if possible. Note that the default is currently
unspecified.

A callback may be specified with the C<-fillcb> option and will be
called after the tree is filled.
