The FNC Page Control has a property Pages that you must double-click to see some page properties that are not accessible any other way.
There are two properties there: .Visible and .TabVisible
In the VCL, you can set TabVisible := False and still show the page by setting ActivePageIndex to it.
In this case, the two properties seem to be tied together: if you check one, the other one is checked, and vice versa.
I want to be able to have a "Filter" button that shows a page when it's clicked but its tab is never visible.
However, with TabVisible set to False, that page won't show when you set ActivePageIndex to that Page#.
Is this "as-designed" or an oversight?
