runtime pagecontrol with fixed tabsheets on variable number of runtime created tabsheets

Hi
My app creates a variable number of tabsheets at runtime onto a designtime pagecontrol.  That part work fine.  These tabsheets all have the designtime pagecontrol as parent.

the app needs to create a unique 5 tabsheet pagecontrol on each tabsheet created at runtime.
I am not sure how to assign the created pagecontrols to the parent tabsheet of the first pagecontrol.
The only object on each of the 5 tabsheets is a grid of unique records populated before the pagecontrils are displayed.

Do I need to free all the created tabsheets and pagecontrols manually?

depends how you create them. if you use

whatever.create(soemthing);

then no. if you use

whatever.create(nil);

then, maybe. I say maybe, because you can still add all of them to a TObjectList created with .create(true); and that will take care of freeing them. but that again requires code from you, first to create the object list, then to add everything created with nil to it and finally to destroy the object list.

I would recommend using the first way: create(something).

where something can be any tcomponent or descendant, really. usually you would use the same component which is the parent as well since once the parent dies, there is no sense (usually) for the child to live.

Ok,
How does one reference the created tabsheet as the parent in the create method?  I'm not sure exactly how to do that.

Sorry,
Stupid question.

What do I use as the argument for the new pagecontrols and the new tabsheets create method to avoid having to deal with it myself?

I know how to reassign the parent of those objects.

let's assume the parent is "blabla" (a component).

you will do:

page:=tpagecontrol.create(blabla);
page.parent:=blabla;
tab1:=ttabsheet.create(page);
tab1.parent:=page;
get it?

I don't know who is the parent of who (maybe it's the late hours here) so I cannot give you specific example for your code, but hopefully you can logically transcribe the "blabla" to your actual code :)

ciuly,
I was trying to borrow code from another pagecontrol question and should have realized that I needed to assign the create to a variable in order to use it later.

Thanks
