TPanel: A defined rectangular area of the form into which other components can be placed to group them functionally and geographically
Most of the properties are defined in ancestor classes including TCustomPanel, TCustomControl and TWinControl
Any controls such as buttons or check boxes that are placed inside the panel become its children, and inherit many of its properties. If the Panel is moved, the child controls move with it. Any part of a child control that falls outside the panel becomes invisible.
