You got some magic things, if you are using argument like this :
:Parameters:
`<empty>`
To make dispatching work, you need at least one
input listener. If not, application will leave.
(MTWindow act as an input listener)
`widget`
If you pass only a widget, a MTWindow will be created,
and your widget will be added on the window as the root
widget.
`slave`
No event dispatching are done. This will be your job.
`widget + slave`
No event dispatching are done. This will be your job, but
we are trying to get the window (must be created by you before),
and add the widget on it. Very usefull for embedding PyMT
in another toolkit. (like Qt, check pymt-designed)
