Question about using of xpStyle components by rhoStyle

Hi.

  I'm using xpStyle components 2.6
(http://www.rhostyle.com/xpStyle.html
) and I want to add my own
button in main window title. I drop TxpWindow component on my form,
set window style to "XPOlive" and define OnCustomButtonDraw event.

  Then I rum my application, but my button does not appear in window
title.

  Anybody knows how to solve this problem?

Thank you.
