Add a radio button widget to the scene.

Radio buttons work in groups. Only one button in a group can be on at at the same time. Typically you should add two or more buttons belonging to a same radio button group. Each button should be passed a callback function. This function will be called when a radio button in a group is switched on, assuming it was not already on.

Parameters:

valuebool, default: False

The default state of the button. If multiple buttons in the same group are initialized with to True state, only the last initialized button will remain on.

title: str, optional

String title to be displayed next to the radio button.

positionsequence[float], default: (10.0, 10.0)

The absolute coordinates of the bottom left point of the button.
