Becouse your name is in last revision (1.12) of wincontrol.inc, and
becouse I couldn't find who is maintainer of TWinControl at Lasarus
web page, I address to you.
I've read code and found smth strange in
Procedure TWinControl.AlignControl(AControl : TControl);
Everywhere in code such construction used: TControl(Owner)
But it seems to me that it's wrong and Parent should be used instead.
There are difference between Parent and Owner
Parent - visual entity which have our TWinControl as one of children
Owner - container which has ownership relation to our TWinControl.
For example, Owner will Destroy our TWinControl when in his destructor.
And Owner can be non-visual component (not derived fron TControl).
Maybe this can be of use for you.
Or maybe conception of Parent/Owner is not working now in Lasarus.
BTW, who is maintainer (main developer) for TWinControl
"It would be the greatest mistake to think"
