FLTK::RadioButton - Button with a circle indicator to it's left, turning it on turns off all other radio buttons in the same Group

Description ^

This button turns the value( ) on when clicked, and turns all other RadioButton widgets in the same group off. It displays a round dot to show the user the current status.

You can control the color of the circle with color( ) and the color of the dot with textcolor( ). You can make it draw different colors when turned on by setting selection_color( ) and selection_textcolor( ) on the widget (these are ignored if set in an inherited style( )).

If you want, you can make any other button act like a RadioButton by doing type(FLTK::Button::RADIO) to it. Be sure to lay out and decorate your interface so it is clear to the user that they are radio buttons.
