XmToggleButtonSetState - A ToggleButton function that sets or changes the current state
void XmToggleButtonSetState (widget, state, notify)
XmToggleButtonSetState sets or changes the ToggleButton's current state. Specifies the ToggleButton widget ID. Specifies a Boolean value that indicates whether the ToggleButton state is selected or unselected. If True, the button state is selected; if False, the button state is unselected. Indicates whether XmNvalueChangedCallback is called; it can be either True or False. The XmNvalueChangedCallback is only called when this function changes the state of the ToggleButton. When this argument is True and the ToggleButton is a child of a RowColumn widget whose XmNradioBehavior is True, setting the ToggleButton causes other ToggleButton and ToggleButtonGadget children of the RowColumn to be unselected.
