An option button control com.sun.star.awt.UnoControlRadioButton is a simple switch with two states, that is selected by the user. Usually option buttons are used in groups to display several options, that the user may select. While option buttons and check boxes seem to be similar, selecting one option button deselects all the other option buttons in the same group.

Usually a group box, or horizontal and vertical lines are used, because those controls visually group the option buttons together, but in principal this can be any control. There is no functional relationship between an option button and a group box. Option buttons are grouped through consecutive tab indices only.

The state of an option button is accessed by the State property, where 0 is not checked and 1 is checked.

  Function IsChecked( oOptionButtonModel As Object ) As Boolean
      Dim bChecked As Boolean
      If oOptionButtonModel.State = 1 Then
          bChecked = True
      Else
          bChecked = False
      End If
      IsChecked = bChecked
  End Function
