Hi Daniel: Sadly, no. It's primarily because there's only one querymap for
potentially
all the layers so symbolization could become quite complex as different layers
are processed.
A better solution is to store a selection style with each layer. Depending on
your application
you might be able to work around this limitation using dynamic expressions. For
example:
# selected feature layer
LAYER
NAME 'selected'
...
LABELITEM 'keyfield'
CLASS
EXPRESSION '%keyvalue%'
...styles to draw the feature in a selected manner...
METADATA
keyvalue_validation_pattern 'some regex to make sure the keyvalue is of
the proper form'
END
END
END
Then if using the CGI you could call MapServer with a primary key from the
selected
feature, e.g.:
/cgi-bin/mapserv?map=...&layer=selected&keyvalue=1234
If your app knows stuff about the selected feature (either as part of a
template presentation or
perhaps the query was done via ajax) then this works nicely.

Hello MapServer Users,
I've been using the Querymap-Feature of MapServer. As I understand the
objects are highlighted by changing the color. It would be very nice to
have the possibility to define other style-properties like SIZE,
OUTLINECOLOR, etc. Is this possible?
Best regards
Daniel Degasperi
