title: Delphi: scroll PageControl tab area to the right
body: <p>After runtime creation of new tabs, I see that last tab is overlapped by system [&lt;] and [>] buttons in the tab header area. How to scroll this area to the rightmost position? Img from one c++ app which looks same as my app. Delphi 7.</p>
