Tooltip not shown in swt

I am trying to set tooltip for items in a TreeViewer in swt. 

ColumnViewerToolTipSupport.enableFor(viewer);

DocumentTreeLabelProvider labelProvider = new DocumentTreeLabelProvider();
viewer.setLabelProvider(new DecoratingLabelProvider(labelProvider, labelProvider));

The labelProvider class looks like this: 

public class DocumentTreeLabelProvider extends ColumnLabelProvider implements ILabelDecorator {
    ...

    @Override
    public String getToolTipText(Object element) {
        return "tooltip"; //$NON-NLS-1$
    }
    ...
}

The problem is that tooltips are never displayed and I have no idea why ??

ColumnViewerToolTipSupport only looks at the main label provider for the column (DecoratingLabelProvider in your case).

You will have to use a label provider which supports tool tips for the main label provider, DecoratingStyledCellLabelProvider for example. Extend that label provider to add the getToolTipText method.
