Re: [riena-dev] Questions related to CompositeTable 
Hi Stefan,

please see my inlined response for details. Your questions are all
related to limitations of CT, so we will need to submit patches for
something to happen. I would be quite interested in doing that, having
already submitted a few patches against CT.

There is an open bugzilla request to support this - see 186270. At a
minimum it needs a patch that works with current code.

I opened Bug 287624. This works as you describe, ONLY if there are no
composites used inside the Row class (i.e. no createCell()). Once
there are composites inside the Row-Composite the focus stays within
those.

Not supported by GridRowLayout / ResizableGridRowLayout. See Bug
287625. I think this would be relatively easy to add.

As a workaround you can replace Row():
   setLayout(new ResizableGridRowLayout())
with
   setLayout(new GridLayout(3, false));

only then will createCell():
   GridDataFactory.swtDefaults().grab(false, false).align(SWT.FILL,
SWT.TOP).applyTo(cell);

have any effect. However doing this means that you lose the ability to
resize via the header (that is what ResizableGridRowLayout provides).
In that case should probably remove the Header all together.

Best regards,
Elias.
