| 26 | * CcShell is an interface that represents an instance of a control | ||
| 27 | * center shell. It provides access to some of the properties of the shell | ||
| 28 | * that panels will need to read or change. When a panel is created it has an | ||
| 29 | * instance of CcShell available that represents the current shell. | ||
