TToggleBox is TCustomCheckBox descendant which implements a labelled control with state values like a check box control. TToggleBox differs from TCheckBox in that it displays only the Caption text for the control; the graphical check mark representation is not used. TToggleBox is similar in appearance to a push button control. The control state determines whether the button is drawn using its up or down position.
The programmer must ensure that the OnClick event handler recognizes the State of the control, takes the appropriate Action, and stores the State into the appropriate storage.
