Hi,
i am trying to set up a table containing EObject instances:
TableViewer viewer = new TableViewer(myTable);
//viewer.setLabelProvider(new AdapterFactoryLabelProvider(new
MyModelItemProviderAdapterFactory()));
viewer.add(myEObjectList.toArray());
If I use this without a LableProvider the rows are created i can see the
standard toString representations of the EObjects. But if i use the
Labelprovider Second line in the snippet), the rows remain white. I use
the same LabelProvider for a treeview, where it works fine:
public class LabelProvider extends AdapterFactoryLabelProvider implements
ILabelProvider {
public LabelProvider() {
super(new ModelItemProviderAdapterFactory());
}
}
Thanks for any help.

Hi
I finally found the problem:
1. I had to turn on "Create column provider" in genModel
2. Set the lableprovider before populating the table!
Anyway, thanks Ed!
