It is important to understand the concept of a component's "parent".

When you place a component such as a TButton on a form, the form becomes it's "parent". This is a  visual "containership".

If you now place a TPanel on a form, the same thing happens, but when you drop another TButton on the panel, the panel becomes it's parent, not the form.

In fact if you try and move the second button, it's visibility is "contained" in the bounds of the panel.

So the idea to "bring to front" or modify the "Z-order" is not really relevant here.

The easy way to handle your situation is to just cut and paste - ie cut the component you want to move, and paste it into the component that can contain other components( eg TPanel, TGroupBox, TPageControl etc ). For instance,  you cannot have a TButton contain other components.

kind regards

Gary

PS: Don't get confused with a component's "owner" which is responsible fo it's destruction.
