public class RadioButtonSet

extends Object

implements HTMLItem

The class RadioButtonSet is used to create a set of HTML radio buttons to be used in Forms. The set of radio buttons are physically connected so that selecting one button in the set automatically de-selects the previously selected button. All radio buttons in one RadioButtonSet must have the same in the NAME tag, that's what makes a number of radio buttons connected, i.e. gives the buttons their "radio button" property. To create a radio button set, inside an HTML form, that looks like this:

you would need HTML code like this:

   Radio buttons: 
   <INPUT TYPE="radio" NAME="myRadio" VALUE="radio1">Radio 1
   <INPUT TYPE="radio" NAME="myRadio" VALUE="radio2">Radio 2
   <INPUT TYPE="radio" NAME="myRadio" VALUE="radio3">Radio 3
 

   RadioButtonSet rbs = new RadioButtonSet("myRadio", "Radio buttons:", false);
   rbs.addRadioButton("radio1", "Radio 1");
   rbs.addRadioButton("radio2", "Radio 2");
   rbs.addRadioButton("radio3", "Radio 3");
   String myString = rbs.toHTML();
