[Biojava-l] AlignmentRenderer works with TranslatedSequencePanel but not SequencePanel???

[Mark Southern]

The attached example code renders an alignment when used with a
TranslatedSequencePanel but not with a SequencePanel - the SequencePanel
remains blank.

A diff of TranslatedSequencePanel and SequencePanel shows they are quite
different. I am not sure what is going on.


Can anyone give me some pointers as to how to get this to work in a
SequencePanel? I would prefer this since SequencePanel can be scrolled in a
JScrollPane and TranslatedSequencePanel cannot.

Cheers,

Mark.
