Radio Button

Radio buttons are used to select one of several options, usually within a dialog box. A radio button contains a small circle with text next to it. When selected, the circle has a smaller, filled circle inside it. Selecting one button in a set deselects the previously selected button, so only one of the options in the set is selected at a time.

The window class name for a radio button is "BUTTON".
