ENH: clear() method for widgets.RadioButtons

[raamana]

Enhancement proposed

Right now, RadioButtons can be created without activating any of the individual buttons, but they can not be cleared once created. It can be achieved in a dirty way, by hacking properties of the associated artists. However, I feel they need to come with a clear() method which deactivates previously selected one - it simply has to do two things: update the button colour and set value_selected to None. If this is acceptable, I'll be happy to send in a PR.

I think this is a reasonable feature request. Would it make sense to also add such a convenience feature to the check boxes widget?

that's true - I can do that as well.

Checkboxes can at least be all unchecked individually. So there would be no definitive need for such feature as in the case of radio buttons. But since this would probably be equally easy to add, why not.

I also would like to modify the behaviour of CheckButtons.set_active() method - which is currently a toggle function - to reflect its name better (sets a button regardless of its previous state). If its important to keep the current behaviour as it reflects the mouse click behaviour, we should rename it as toggle to reduce the cognitive overload and confusion :)

We are sticklers with regards to backwards compatibility. Yes, the name choice wasn't great. What would be fine is to accept an optional boolean argument that would be the state to set the checkbox to.

But feel free to update the docstring of the method to make this behaviour more apparent.
