[Bioperl-l] accessing params for custom glyphs?

[Smithies, Russell]

This is probably more of a Perl OO problem I'm having, but can anyone
tell me how to access a parameter when I create a custom glyph?

I've created a panel in the usual way then I add a feature with
'my_glyph' and want to pass the value of -new_parameter to the glyph
drawing code.

    $panel->add_track( $feature,
    			-font => gdSmallFont,
			-glyph => 'my_glyph' ,
			-height => 10,
                		-label  => 1,
                		-strand => "forward",
                		-new_parameter => "test",


In my_glyph.pm, I have the usual draw_component sub:

sub draw_component {
  my $self = shift;
  my $gd = shift;
  my ($x1,$y1,$x2,$y2) = $self->bounds(@_);
  my $fg = $self->fgcolor;
  my $params = $self->??????????   <<--- how do I access the value of
"new_parameter" set in the panel drawing code?

  $gd->line($x1,$y1,$x2,$y2,$fg);
  $gd->line($x1,$y2,$x2,$y1,$fg);

}

Any ideas?

Thanx,
