Hi ,

I was using nebula grid which is like a swt widget.
Due to some problem i have to use a viewer.While searching i have got
something like Gridviewer.I cannot use tableviewer cause table dosent
support row headers.

When i use the class GridViewer it extends BaseTableviewer.When i searched
in j face directory structure i dint find any class as
BaseTableViewer.While searching i again found out that its name is changed
to AbstarctTableViewer.can any one throw some light in this issue?

if i use abstarctableViewer as the class for GridViewer to extend it asks
for some more methods to be overridden.How will this impact..?

Hi,

Well JFace in 3.3 opened its API to allow external components to use it
easily to provide implementations for their widgets. The current problem
of Nebula is that the JFace API is not stable yet (API freeze is M5) and
a subject to change even in the next few weeks. Nebula is always going
to be one step behind because of this.

The history for AbstractTableViewer can be read in the following bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=154329

AbstractTableViewer is certainly the class who has to be subclassed and
I think Chris already has a working solution but is waiting for
potential API-Changes mentioned in the following bugs:

- https://bugs.eclipse.org/bugs/show_bug.cgi?id=167325
will break current API

- https://bugs.eclipse.org/bugs/show_bug.cgi?id=151295
adds new feature which maybe has to be reimplemented by Nebula

- https://bugs.eclipse.org/bugs/show_bug.cgi?id=167323
Provide a subclassable AbstractTreeViewer for Nebula

But Chris can certainly tell you more about the whole thing (at least
for the Nebface-Implementations). If you need informations on JFace I'm
certainly the one to ask because all the code providing those new
features and has been contributed by me. I hope I can get all the
mentioned stuff in for 3.3M5 but I can't promise because it's not my
decision ;-)

If you ask me, JFace provides so many new features for editing and MVC
concepts in 3.3 that together with Nebula's widgets it will push Eclipse
in 3.3 a big step forward no matter if you use the native widgets or
custom drawn ones like those from Nebula.

Feel free to ask questions provide ideas for new classes, ... .

The grid viewer is under active development and will likely be released
very soon. I'm just real busy right now.

Agreed 100%. Kudos to all the work you've done in JFace Tom. I think
you've made a big difference.

if i use the grid which serves all my GUI functinality ,it cannot be
registered for Iselectionprovider .

There can be one way though.!My grid has to implement the
iselectionprovider and provide the implementation for it.

can any one of u help me out in this..?can u provide a sample snippet of
how to provide implementation for iselectionprovider..or , or is it better
i go with gridviewer ..?

Hi,

Please wait for GridViewer to be ready it will be the best choice IMHO
because you get many features new in 3.3 for free. If you need a
solution tomorrow you need to implement the viewer your own but then you
won't profit from the great new things mentioned in my last mail.
