No, I'm sorry, I'm not a Lazarus developer.

Ah, OK. I inserted the solution from Ondrej in my current project and it 
really seems to be the better approach. If there is no other opinion to 
that topic, you can ignore my initial hint.

Now, there is only the gap of Lazarus and Delphi compatibility versus 
Lazarus consistency.
I don't know, how many other Lazarus user use the TPageControl.OnChange 
event in the same manner as I do. If no one else, there is no barrier to 
change it to Delphis behaviour ;)

Offtopic: Maybe is Delphis behaviour not really consistent. For example, 
TEdit.OnChange is fired, if the TEdit.Text is changed by user or code.

Kind regards
