Problem with component containing component

[Mateusz [PEYN] Adamus]

Hi

I'm writing really simple (doesn't look that way anymore) component.

I want to create a panel with another panel in it.

Main panel is MyPanel and inner panel is just InnerPanel.

OK. So i started with creating new component which inherits from TPanel.

Then I overidden constructor and added code creating the InnerPanel

<delphi>

FInnerPanel := TPanel.Create( self );
FInnerPanel.Parent := self;
FInnerPanel.Align := alTop;
FInnerPanel.Caption := 'InnerPanel1';

</delphi>

OK, I installed it and put MyPanel on my form in some test project.
Everything looked great - I had panel with my InnerPanel.

But then I tried to put some other components on my InnerPanel and hit
the wall. I can't put components on it :-( It looks like delphi doesn't
even know that there is panel inside MyPanel.

So, my question is: How can I change MyPanel so that Delphi would see
InnerPanel?

I know it can be done 'couse there is PageControl, it has TabSheets in
it and Delphi sees them.

On another group someone told me to use DefineProperties procedures. So
I looked on google and found something but I can't make any thing of it
:-( It would be really great if you could make some tutorial source code
for me.

TIA
