Tab between fields in TableViewer

Question

What I\'d like to do is be able to tab between elements in table.

I currently am creating my table like this.

this.tableViewer = 
            new T         


        

Answer 1

I couldn't get the desired behavior with a TraverseListener (it would not traverse within the table), and I had trouble getting it to work with a FocusCellManager and CellNavigationStrategy. I finally found this solution that enables me to tab from column to column within a row and automatically activate the editor.

Viewer viewer =  ...

TableViewerFocusCellManager focusCellManager =
    new TableViewerFocusCellManager(
        viewer,
        new FocusCellHighlighter(viewer) {});

ColumnViewerEditorActivationStrategy editorActivationStrategy =
    new ColumnViewerEditorActivationStrategy(viewer) {

            @Override
            protected boolean isEditorActivationEvent(
                ColumnViewerEditorActivationEvent event) {
                    ViewerCell cell = (ViewerCell) event.getSource();
                   return cell.getColumnIndex() == 1 || cell.getColumnIndex() == 2;
            }

};

TableViewerEditor.create(viewer, focusCellManager, editorActivationStrategy,
    TableViewerEditor.TABBING_HORIZONTAL);
