Detailed Description

This interface handles the data for widgets with 3 possible states. The most common widgets that use this data interface are

Radio buttons and Checkboxes.

Member Enumeration Documentation

anonymous enum

enum for DefaultIID to make UseDefaultIID() work for this interface

3 possible states for the widget

virtual void ITriStateControlData::Deselect	(	bool16	invalidate = `kTrue`,
		bool16	notifyOfChange = `kTrue`
	)

pure virtual

Set the state of the widget to be kUnselected. Optionally invalidate and notify observers

virtual TriState ITriStateControlData::GetState ( ) const

pure virtual

Get the current state of the widget

virtual bool16 ITriStateControlData::IsDeselected ( ) const

pure virtual

Check if the state of the widget is currently kUnselected

virtual bool16 ITriStateControlData::IsSelected ( ) const

pure virtual

Check if the state of the widget is currently kSelected

virtual bool16 ITriStateControlData::IsUnknown ( ) const

pure virtual

Check if the state of the widget is currently kUnknown

virtual void ITriStateControlData::Select	(	bool16	invalidate = `kTrue`,
		bool16	notifyOfChange = `kTrue`
	)

pure virtual

Set the state of the widget to be kSelected. Optionally invalidate and notify observers

virtual void ITriStateControlData::SetState	(	TriState	newState,
		bool16	invalidate = `kTrue`,
		bool16	notifyOfChange = `kTrue`
	)

pure virtual

Set the state of the widget to a new state. Optionally invalidate and notify observers

virtual void ITriStateControlData::SetUnknown	(	bool16	invalidate = `kTrue`,
		bool16	notifyOfChange = `kTrue`
	)

pure virtual

Set the state of the widget to be kUnknown. Optionally invalidate and notify observers
