IFRadioController

The IFRadioController object keeps track of all IFRadioButton components in one group and makes sure only one is selected. Radio buttons can be added to a group either by passing them to the radio controller through the add() method, or by specifying a controller when creating a new radio button.

Method Summary

IFRadioController()
IFRadioController(String label)

• label, the name of the radio button group.

add(IFRadioButton button)

• Adds a radio button to the controller's list of buttons it manages.
• button, the button to be added.

remove(IFRadioButton button)

• Removes a radio button from the controller's list of buttons it controls.
• button, the button to be removed.

getSelected()

• Returns the currently selected `IFRadioButton` object. If none is selected, it returns `null`.

getSelectedIndex()

• Returns the numerical index of the currently selected `IFRadioButton`. If none is selected, its value is `-1`.
