Question

My question is How can we find the currently selected column number in the selected row of a SWT Table in Eclipse RCP?

Answer 1

Inside a Listener – e.g. for SWT.Selection – you can use viewer.getCell(...) as illustrated in the following example:

myTableViewer.getTable().addListener(SWT.Selection, new Listener() {
    @Override
    public void handleEvent(Event event) {
        Point p = new Point(event.x, event.y);
        ViewerCell cell = myTableViewer.getCell(p);
        int columnIndex = cell.getColumnIndex();
        //...
    }
});
