Re: [nebula-dev] Lazy initialisation of grid

[Christopher J Gross <chris.gross@xxxxxxxxxx>]

Hi Jonathan,

The Grid supports SWT.VIRTUAL that would
primarily work for your scenario.  The virtual functionality will
work like Table.  This will tell you when a row's data is required.
 This should likely be enough but does not have a method to let you
know when you can release data that is no longer necessary.  It is
something you could reasonably do yourself.  Perhaps just set a limit
on the # of model classes you want at any given time and when new data
is required, release the least recently accessed models to make room.  

Regards,
-Chris

Hi. I am in the need of a spreadsheet widget that can
be used for viewing large amounts of data. More than what would be reasonable
to have in memory at the same time. I would need to be able to just load
the cells currently viewed (from ex. a database). I wonder if this can
be done (without to much work) with the Grid widget? 

My feeling is that I would have to extend the GridItem class but that feels
a little bit like biting of more than i can chew...

Do you have any suggestions?
