Hi,

current implementation of GridViewer found in CVS is a work in progress.
If you need a working solution you'll have to check out the relevant
projects from CVS and apply the patch from the following bug to JFace
and Nebface from CVS-HEAD:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=172646

thanks tom!

can u help me in one more problem..?

Now if i use GridViewer constructor which takes in a grid object like

public GridViewer(Grid grid){
}

For the grid which will be passed to grid viewer will have row headers
and column headers already constucted.

This implies that on a grid viewer a grid is placed with row headers and
column headers.Is it possible that now if i use content providers and
label providers now for the viewer so that the content and label are set
on the grid like the grid items..?
i thought of the above case as i need columnheaders and roe headers..!

can i achieve it in that way or can i get column headers and row headers
using gridviewercolumn and gridviewerrow classes.and actually
gridviewerRow class has some problem.it says that super class constructor
not visible..!

can u give any suggestion regarding this?

Hi,

I'll take a look at when I have time but I think the best thing would be
if you wait for next week where we will hopefully finish Viewer-Support
in JFace in M6 cycle. Then you don't need any CVS-Patches who maybe
don't cleanly apply to HEAD because there have been other changes.

I think Chris can maybe tell you more at when the Viewer code will
afterwards walk to nebface but because I always update because Grid is
my current test case I expect to see a commit in nebface shortly after
we have fixed JFace-API, sad enough we failed the M5 freeze but we
didn't wanted to rush in with new API would have to remove in M6 because
it doesn't satisfied our (customers) needs.

JFace is one of central projects which has very strict rules and adding
API is not a process of a day there but we evolved great 3.3 ;-) For the
time being I'd say you can use TableViewer and switch to gridviewer
afterwards. Subscribe yourself to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=172646 and you'll get
informed when we released a fix.

Hi,

This is a compile time issue and as already said I can't reproduce on my
system.

Well,

column-headers won't be accessible through JFace-APIs you always need to
use GridColumn#setText() or GridViewerColumn#getColumn()#setText(), ...

How to access row-headers is a question will have to think about and I
must admit that I haven't thought about this until now because there's
nothing SWT support so maybe GridViewer needs some extra bits for this
but I'm not 100% sure how to deal with that for now. Do you want to have
LabelProvider-Support for Row-Headers, this is not an easy task because
when structural changes happen insert/remove this would mean that all
subsequent rows have to be updated.

Yes. But you can use I-Builds who are created in between. I'm sorry that
we didn't made it to M5 but time was too short and there are very strict
rules in eclipse specially for so central components like JFace (if
JFace is broken the whole eclipse is broken because it's the foundation
of the whole UI-Framework as much as SWT)

We could have rushed the new API in for M5 but we had some small issues
with the current implementation (nothing you need to be worried about as
a customer but you don't ever get a guarantee from me that there won't
be changes). Because of the things outline above (foundation component,
....) we decided together (Boris = JFace-Viewers-Lead and me) that it's
not the best to bring in things in the last minute.

Now because we didn't added the required bits for M5 we need UI-PMC
approval to get the API in for M6 but we are confident that our API
change is so important (bring so much power to viewers) that we get the
approval! I think Chris is only waiting for us to finish the proposed
API changes because he gets a viewer for free ;-)

My current setup is developing with Eclipse 3.3M4 with a checkout of the
platform-ui from CVS and Nebula/Nebface but I think there have been
minor changes to JFace HEAD so the patch won't apply any more cleanly
but I haven't tried.

Aferwards apply the patch from the bug I mentionned in one of previous
mails and everything should compile.

Hi,

Please read my answer in the other thread how to get support with a
patched versions from JFace, Nebula, ... CVS-HEAD. In the patch also an
example how to use GridViewer is included.

And as said I currently don't have any solution for you when it comes to
row-headers in terms of viewers some smart people have to jump up fast
if JFace should provide some API for this I don't have time to provide
any solution in time, which doesn't mean that you can't do all this your
own.
