copied!<p>After long research I haven't found such feature so I guess there's any. Tk is very simple interface, which allows programmer to build 'high-level' features from the basics. So my desired behaviour this way.</p> <pre><code>def onDoubleClick(self, event): ''' Executed, when a row is double-clicked.
