This snippet traps double clicks in a Sublime Text plugin. I kid you not.

gistfile1.py

trapping_views = {VIEW_BREAKPOINT: dbg.callbacks.on_breakpoints_dblclick,VIEW_STACK: dbg.callbacks.on_stack_dblclick}

class UnityTrapDoubleclickCommand(TextCommand):
    def run_(self, args):
        print 'on dbl click'
        special_handler = trapping_views.get(self.view.name(),None)
        print args

        if not special_handler is None:
            line = self.view.line(self.view.sel()[0])
            special_handler(line)
        else:   # default handling by Sublime Text
            system_command = args["command"] if "command" in args else None
            if system_command is None: return
            system_args = dict({"event": args["event"]}.items() + args["args"].items())
            self.view.run_command(system_command, system_args)
