TickerDialog not showing

[fordprefect]

P.P.S:

there seems to be an error in an error message; when you supply only one positional argument to addBoolLabelItem, the error reads:
TypeError: addBoolLabelItem() takes at least 1 argument (2 given) which should most likely be the other way round (at least 2 arguments and just 1 given)

and I suggest to add documentation strings to the BasicConfigurable.add* resources, to ease scripting (I use that tooltip feature in the IDE quite a lot). Pleeeeease...
