How to use it like TPageControl
Make some new panel, which will be like TPageControl. Place ATTabs on it, make Align=alTop. Now you create several Forms or Frames onto this panel (they have Parent:=Panel1). How to switch these frames on changing tabs?
1) Add tabs OnChange event handler. 2) In this event handler make a) hiding all frames, b) showing frame, which is assigned to current TabIndex.
When you create a new tab, you can set its TabObject property. Set TabObject to a frame. When OnChage occurs, get TabIndex, call GetTabData for this index, and read TabObject for this tab. Show frame, which is stored in this TabObject, hide all others.
