Feature methods in callbacks
Hi
I'm having trouble with a callback for a balloon popup. So far I have:
balloon hover = sub {
my $f = shift;
my ($note) = $f->notes;
# Note = truncated Notes field. Would like to show more but
# can't get $f->desc to work, and $description doesn't work
# either
return '<b>'.$f->display_name.'</b><br> '.$f->type.' on '.$f->ref.' '.$f->start.' to
'.$f->end.'.<br> Description '.$note.'<br> Match coordinates '.$f->target.'<br> Click for more details.';
}
I'd like to show the full "Note" field, which I realise can be accessed using $description; but when I add
other calls to the feature object e.g. $f->target, $description no longer works.
$f->desc returns a number which I guess is an array length - a surprise to me, because the
Bio::SeqFeature::Lite docs say desc returns a string.
$f->notes (as shown in the stanza) returns a truncated description, however I'd like to show the full caboodle.
Can anyone tell me how to extract the full note field?
I believe the feature class is Bio::SeqFeature::Lite, but a lot of the methods are undocumented and some
which purportedly work according to the GBrowse tutorial aren't listed in the Bio::SeqFeature::Lite
docs. Am I looking at the wrong class?
Thanks :)
