Small question: Can the DataBinding stuff only be done with EMF? When I go to the Bindings tab I can find my TableViewer but not the model I created.

So, to load the table viewer I pass a workgroup as the input object as in: tableviewer.setInput(workgroup).
You don’t see this happening anywhere in the code, but eventually eclipse passes the workgroup to the ContentProvider getElements method that you mention. I know the input element is a Workgroup, so in the getElements method I cast inputElement to Workgroup. I then use the workgroup’s memberSet to derive the array of objects that the method must return:

public Object[] getElements(Object inputElement) {
Workgroup w = (Workgroup) inputElement;
return w.getMemberSet().toArray();
}


I hope this clarifies.

You made a nice example, which is probably very usefull for me.
I was just wondering, is it somehow possible to see what code is in the classes:
com.oxbsystems.study.domain.workgroup.Person and
com.oxbsystems.study.domain.workgroup.Workgroup ?

Because I still do not really understand how you can return the Workgroup in the ContentProvider.getElements(Object InputElement)

Would be great if you can provide it to me.

Kind regards,

As you point out, all other columns will be resized automatically. The example uses only ColumnWeightData, but there are situations in which it makes sense to also use ColumnPixelData for some columns (not all). Perhaps you will get a behavior that is closer to what you expect by using the following code for the first column:
layout.setColumnData(tblclmnFirst, new ColumnPixelData(150, true, true));

This will set the first column to 150 pixels and the column will not resize if other columns get resized. However, if the first column gets resized, the other columns will get resized as well.
