                   java.lang.String label)

Creates a new radio associated with a particular group, and initialized with the given HTML label. All radio buttons associated with the same group name belong to a mutually-exclusive set.

Creates a new radio button associated with a particular group, and initialized with the given label (optionally treated as HTML). All radio buttons associated with the same group name belong to a mutually-exclusive set. Radio buttons are grouped by their name attribute, so changing their name using the setName() method will also change their associated group.

label - this radio button's label

asHTML - true to treat the specified label as HTML

Method Detail

setName

public void setName(java.lang.String name)

If changing this group name results in a new radio group with multiple radio buttons selected, this radio button will remain selected and the other radio buttons will be unselected.

Specified by:

setName in interface HasName

Overrides:

setName in class CheckBox

Parameters:

name - name the group with which to associate the radio button
