WkRadioButtonView

WkRadioButton provides a customizable version of a standard radio button. It has a boolean value that is set to true when the box is checked and false when the box is unchecked. The value is toggled on and off by clicking on the radio button. The state of a checkbox can be queried and changed using the # selection and #set messages, respectively. Radiobuttons trigger a selectionChanged event when their state is changed. The textual label that appears to the right of the check box can be changed at runtime with the #labelString: message.
