| 13 | wxRenderer class is used to draw all wxWindows controls. This is an ABC and |
| 14 | the look of the application is determined by the concrete derivation of |
| 15 | wxRenderer used in the program. |
| 16 | |
| 17 | It also contains a few static methods which may be used by the concrete |
| 18 | renderers and provide the functionality which is often similar or identical |
| 19 | in all renderers (using inheritance here would be more restrictive as the |
| 20 | given concrete renderer may need an arbitrary subset of the base class |
| 21 | methods) |
