Grid: setting checked state of the item according to the model [message #478913]

Hi,

We are using GridTableViewer in our project, and while it works fine
updating item texts and images, I couldn't find the way to update checked
state of the item for a certain column according to the model changes. Can
anyone advise on how to do this? For now we only need to update it at the
grid creation time, so we can just do that by hand, but we'll definitely
need to track real-time changes in the future.

Thanks in advance,
Stanislav

I managed to overcome this by extending GridTableViewer and doing the job
in doUpdateItem(). However, my solution is hardcoded to work with my
model. I'd like (and I think we all would like) to have a generic
approach, something similar to a CheckboxTableViewer for default SWT
table. The one problem that doesn't allow to simply copy the code of the
CheckboxTableViewer is that grid can have any column checkable. I think
CheckboxGridTableViewer should differ in the setCheckStateProvider(),
allowing to set them for different GridViewerColumns, and in
doUpdateItem(), where we need to check all checkStateProviders that were
set and check/uncheck item at necessary indices.

I'd like to write and contribute this stuff, but I fear I won't be able to
find time for this, so if anybody want to help me and all the Nebula
community will greatly appreciate this.

Regards,
Stanislav

At least please file a bugzilla and then one who has time can work on it.
