I'm trying to add stereo to visad as was discussed here:
http://www.unidata.ucar.edu/staff/russ/visad/msg15790.html
and I'm having some problems making it work as part 2 of that email indicated,
extending FancySSCell and SpreadSheet.
The problem I am having is that the only time you can call super() is on the
first line of the constructor. Therefore, the only time I can call
setSSCellClass() is after I call super() in my extension. However, calls to
setSSCellClass() that are performed after the constructor appear to be ignored.
I verified this by directly modifying my copy of SpreadSheet.java to call
setSSCellClass() at the very beginning of StereoSSCell's constructor, with my
extension of FancySSCell. When I did this, the code I added to setup stereo
was called. I then put that call on the last line of the constructor, and
tried again. This time my code was not executed (the constructor does not get
called).
One possible workaround that I am aware of is simply copying the entire
constructor from SpreadSheet.java into my extension of SpreadSheet, but that
would obviously not be considered proper OO programming, and I would like to
know if there is another way to do it.
Thanks,
