/** An abstract base class for button policies.
A state machine implementation of the various button policies used by the
dialogs. Only the policy is implemented here. Separate ButtonController
classes are needed for each GUI implementation.
Policy | ReadOnly | Apply Button | Repeated Apply
========================================================================
OkCancel | N | N | -
OkCancelReadOnly | Y | N | -
OkApplyCancel | N | Y | Y
OkApplyCancelReadOnly | Y | Y | Y
NoRepeatedApply | N | Y | N
NoRepeatedApplyReadOnly | Y | Y | N
Preferences | N | Y | No (Ok-Close)
Ignorant | N/A | N/A | N/A
========================================================================
Policy
The name of the policy
ReadOnly
Does the policy treat read-only docs differently to read-write docs?
This usually means that when an SMI_READ_ONLY input arrives then
all the buttons are disabled except Cancel/Close. The state
machine tracks the inputs (valid/invalid) and has states for all
combinations. When an SMI_READ_WRITE input arrives the appropriate
machine state is entered (just as if the document had always been
read-write).
NOTE: If a dialog doesn't care about the read-only status of a document
(and uses an appropriate policy) it can never get into a read-only state
so isReadOnly() can only ever return false even though the document may
be read-only.
Repeated Apply
Simply means that it is alright to use the Apply button multiple times
without requiring a change of the dialog contents. If no repeating is
allowed the Ok+Apply buttons are deactivated. The Preferences dialog
has its own special version of repeated apply handling because its Ok
button is actually a Save button -- its always reasonable to Save the
preferences if the dialog has changed since the last save.
The IgnorantPolicy is a special case that allows anything.
