Description

Both TForm and TPanel have a DoubleBuffered property inherited from TWinControl.

This property is not visible in the object inspector.

This also begs the question: what other properties are also not visible?

Steps to Reproduce:

>File
>New
>VCL Forms application - C++ builder

>Click on the form
>In OI, look for the DoubleBuffered property. There it isn't.

Workarounds

set the double-buffered property in the constructor.

P.S. double buffering doesn't seem to work at reducing flickering any more.
( it used to help in CBuilder 5, but now it is something aweful)

This is because the property isn't published. In Delphi/C++ Builder 2009 this particular property is published.

Just because a property is available (public), doesn't mean that it is a bug because it isn't published.

Your report should be a feature request, not a bug report.

That's nice.

in CBuilder 5 it was published was it not?
When did it get un-published, and why?
