// This is a mix-in class which handles the enabling policy for
|
|
// CButtonEnabler.
|
|
//
|
|
// For an object to be enabled by a CButtonEnabler attachment, it should
|
|
// mix-in and implement this interface. Note that a default policy is
|
|
// implemented by CButtonEnabler. This is intended for LControl-derived
|
|
// objects which cannot be changed to mix-in MButtonEnablerPolicy and for
|
|
// which the default policy in CButtonEnabler already Does The Right Thingª.
