add Window to Panel

My application has a HorizontalLayout first. On the right component, there is a VerticalLayout. This VerticalLayout has two components. The bottom component needs a lot of Sub-Windows on it. I realize Window must be added into UI. Is there some way to implement my requirements. Thanks!

Maybe what you need are

Panel
s
.

Window
s
are pop-up UI components (like in your OS, most likely :wink: ).
