(as of 3.3) API of ColumnLabelProvider, TableViewerColumn etc.
Google found me some articles explaining why this is a good thing
because you could reuse a labelprovider, for example like this:
public class StockValueProvider extends ColumnLabelProvider {
@Override
public String getText(Object element) {
return ((Stock)element).modification.doubleValue() + "%";
}
Now, what I don't get is why this is supposed to be reusable in any
relevant way - The way I see it, the only case you can use this
StockValueProvider is when you have a public "modification" attribute in
a Stock class. What if this modification attribute is a member of
another class, but I still want it displayed with a percentage sign
appended. Then I write another label provider ? Am I missing something
obvious here ?
So anyway, how do you implement a tooltip that pertains to the entire
row, and not just one column :0)
