| 13 | Renderers are used in wxWindows for two similar but different things: | |
| 14 | (a) wxUniversal uses them to draw everything, i.e. all the control | |
| 15 | (b) all the native ports use them to draw generic controls only | |
| 16 | ||
| 17 | wxUniversal needs more functionality than what is included in the base class | |
| 18 | as it needs to draw stuff like scrollbars which are never going to be | |
| 19 | generic. So we put the bare minimum needed by the native ports here and the | |
| 20 | full wxRenderer class is declared in wx/univ/renderer.h and is only used by | |
| 21 | wxUniveral (although note that native ports can load wxRenderer objects from | |
| 22 | theme DLLs and use them as wxRendererNative ones, of course). | |
