and my comment still stands, as you hover over the property a HINT message should flag the user that it is being
controlled elsewhere and a solution to it..
Yes I do use my brain once in a while @HeavyUser
Items that get locked out due to other settings within the Object inspector should have a little helper notice.
But don't let me stand in the way of progress.
The same happens if you try to change the size in code...
The component itself (could be TLabel, or TSomeThirdPartyComponent) does not tell the IDE why it does not accept the new value. The Component will just ignore the new value. (some 3rd party may throw exceptions, or whatever else...)
Anyway, such a feature (OI, hint/feedback/...) is still do-able. It needs a
generic way to store the additional info in a way design time code can access it.
I think a patch implementing such a generic way in a pre-discussed / bespoken manner, and then a patch which adds such info in the generic way for existing components - those would be welcome.
