Hi Curtis,
Hi Curtis,

Do you know if there is a way to determine whether a Data object of type
Scalar is a "Real" object or a "Text" object? It looks like
DataImpl.getType() (and Data.getType()) returns a MathType but MathType.java
does not have record whether it is a ScalarType and then if it is, whether
it is a RealType or TextType. 

Alternatively, I could use DataUtility.getScalarTypes() to put the scalar
types into a vector as I did before in a method, but I still have the
problem of not being able to extract whether it was a RealType or TextType.

Thanks,
Michelle

Hi Michelle,

SpreadSheet's top-level selectCell(int, int) method calls
FancySSCell.setSelected(boolean). With a little bit of
digging into the visad.ss source code, or even scanning the
Javadocs, you can uncover things like this yourself.
