Comment 2 for bug 736491

@Dylan, can you please merge you work with the proposed branch? I think all this change in one can make sense :)

The doubleclick event is basically broken right now in nux. You should maybe have a look at the double click connect I've hacked in src/PanelTitlebarGrabAreaView.cpp, ensure that the other function is using the same (I remember someone contributed a patch for that, he possibly didn't connect to the same event) and make the button_flags check here which should give the right value.

Does it make sense? Do not hesitate if you need further help ;)
