check box for stacked text, that enables/disables other controls dependent
|
|
on its state.

|
|
|
It is possible to register more controls that have to be enabled/disabled
|

together with this helper object (optionally dependent on the stacked text
|
|
check box), using the function AddDependentWindow(). All registered windows
|
|
are handled on a call of Enable(), or Show(), or on changing the state of
|
|
the "Stacked text" check box.
|
|
|
|
Note: The member function SetStackedState() should be used instead of
|
|
direct modifications of the "Stacked text" check box. Otherwise the update
|
|
mechanism of registered controls will not work.
