Subject Re: DO NOT REPLY [Bug 48962] New: XSSFColor.getRgb() always returns null
Date Tue, 30 Mar 2010 16:50:50 GMT

Have been playng about with some code recently because I was trying to track
down that part of the API where the raw xml is parsed. Sadly, that came to
nought as I was confronted with factory methods that I could not 'hack' in
order to track which concrete call instances were created; these factory
methods were in compiled classes within archives and I did not have access
to the source sadly.

So, I returned to the xml and had a second look. It was at that point that I
saw something a little confusing. I believed I had been setting the
background colour of the cell but that value was not recorded at all in the
xml. What was recorded was the rgb value for the cells foreground colour and
this value was returned correctly when i called the getRgb method on the
XSSFColor object returned by calling the getFillForegroundXSSFColor() method
on the cells style. So, it may be the case that you are trying to
interrogate the wrong object.

Yours
