Ii. Overview

　　　　

A single-choice button is a double-state button that can be selected or not selected. When a single-choice button is not selected, you can press or click it to select it. However, in contrast to the check box, the user cannot unselect the check box once selected. (Note: You can use the code to control the check box. The effect of clicking on the interface is that the check box cannot be unselected once selected ).

Multiple radio buttons are usually used together with radiogroup. When a single-choice group contains multiple single-choice buttons, selecting one of them will cancel other selected single-choice buttons. (For example, see here)

 

Iii. Public Methods

Public void toggle ()

Change the single-choice button to the opposite of the selected one.

If this single-choice button is selected, this method will not switch the single-choice button. (Translator's note: Please refer to the source code:
