Question

There is a column which displaying row numbers, I want to stop user to traverse to cells in it using arrow keys.

In above picture, the cell with text “testDO3” is currently focused and highlighted, the row number column is used to select the whole row, so I want to make it not travsersable.

---

here is my own solution:

tv.getTable().addTraverseListener(new TraverseListener(){
            public void keyTraversed(TraverseEvent e) {
                ViewerCell cell = focusCellManager.getFocusCell();
                if(e.keyCode == SWT.ARROW_LEFT && cell.getColumnIndex() == 2){
                    e.detail = SWT.TRAVERSE_NONE;
                    e.doit = true;
                }
            }

        });

Assuming you’re using JFace cell navigation, then sub-class CellNavigationStrategy and use in constructor of TableViewerFocusCellManager.
