When adding a button, how do I designate which rendering window to show it?

[DYT-Flyer]

A couple of other questions:
Is there a way to prevent the user from min/max/stretching the window when played?
Is there a way to define preference for overlap (button1 appears over button2)?

1. what do you mean "when palyed"?
2. I guess by the order of adding them to the rendering window... but I never tested it..

1. Sorry, I was referring to when Plotter.show() is called.
2. This works, I didn't know if there is a more advanced option.

1. oh, no there isn't, that's owned by the operative system
2. ok, no , the only way is that i guess..

Is there a way to define the size of the buttons?

Yes, e.g.: plotter.addButton(buttonfunc, states=[" Play ","Pause"], size=90)
try vedo --search button
