/** a helper class which monitors certain states of an XWindow2, and ensures
that they ' re consistent with respective properties at an XModel .
For form controls , window states - such as " Enabled " - can be set by various
means . You can set the respective control model property , you can directly manipulate
the XWindow2 , or the state can change implicitly due to VCL actions . In any case ,
we need to ensure that the state does not contradict the model property " too much " .
As an example , consider a form control which , according to its model ' s property , is disabled .
Now when the parent VCL window of the control ' s VCL window is enabled , then the control ' s
window is enabled , too - which contradicts the model property .
A WindowStateGuard helps you preventing such inconsistent states .
The class is not threadsafe .
