[DUG] Move/Paste Controls

[Conor Boyd]

The other thing to note with TBevel specifically is that it is not a
windowed control (it doesn't inherit from TWinControl), so it's never
going to "own" anything placed on it, and you can't place other
components "into" it.
 
Better off using a TPanel, with the borders set as desired, and then
when you drop/drag components on to it, they will be both owned and on
top of the TPanel.
 
Cheers,
 
C.

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.
