[Lazarus] Is TTabControl deprecated?

[Krzysztof]

Hi,

I'm looking for component which have "pages" functionality, but I want
draw it by my self. TPageControl and TNotebook has no events for that.
Only TTabControl has OnDrawTab event and OwnerDraw property but it
seems that this control is incomplete or abandoned:
- OnDrawTab event exists but where draw it? FCanvas is in private
section and there is no public property
- OwerDraw property is not used anywhere

Regards.
