I think the array called Scalars[] in MappingDialog.java holds the input
"map from" fields. Since it is declared private, it will be difficult to
access it from VisadAPI.java without making it public. I'm trying not to
hack into MappingDialog.java to change it to public, but it looks like there
isn't a class variable in BasicSSCell or FancySSCell that references that
cell's MappingDialog box on which I could call a public accessor method that
would return the Scalar[] array. Does anyone know if such a class variable
for a cell's mapping dialog box already exists?

Thanks,
Michelle

Hi, 

I was trying to find a way to select multiple cells at once by pressing
"Control" and selecting the desired cells with the mouse button. Would you
recommend adding more fields in SpreadSheet.java like "CurX2" and "CurY2" to
represent the 2nd cell that was selected by the user? And then add a method
in SpreadSheet.java to handle 2 cells?

Also, for the structure that holds the input fields which are different for
each file that appear in the "map from" column of the dialog box, it would
seem like those fields are stored in "Scalars[]" or "MathTypes[]" declared
in MappingDialog.java, but I'm not sure if one of those is the data
structure holding those fields.

And when I set up my array holding all the possible "Map To" fields that
show up in the mapping dialog when you run the program, I counted 44
different fields in the "Map To" section but in MappingDialog.java, there
are 50 different entries for MapNames[][] and MapTypes[][]. Why don't the 6
extra fields like "Hue" and "Saturation" appear in the dialog box?

Thanks,
Michelle

Hi Curtis,

When I load a data file into a spreadsheet cell, the input fileds such as 
latitude, longitude, etc are different per each file. Do you know which
class 
I can find those fields that appear in the left column of the mapping dialog

box called "Map From"? I'm looking for an array or some data structure that 
holds those fields so that I can map each input field to a corresponding 
Display type such as CylRadius that shows up in the "Map To" section of the 
mapping dialoge box.

Also, when a user clicks with the mouse on a particular cell to select it, I

can access that selected cell with the variables "CurX" and "CurY". However,

do you know if there is a way in the code to access multiple cells when the 
user selects more than 1 cell with the "Control" button and the mouse 
simultaneously?

Thanks,
Michelle
