For now (vsn 2.10.4) there are only a few view classes using controllers; |
52 |
however, over time, more will be converted, since separating the controller |
|
127 | 53 |
offers much more flexibility |
54 |
(although view initialization becomes a bit more complex). |

Those which are interested should redefine the corresponding |

device-Key/Button-Press/Release/Motion methods. |
69 |
Of course, it is always possible to map between device and logical |
|
70 |
coordinates, using `view transformation applyTo/applyInverseTo:', |
|

if both coordinates are required (which is unlikely). |
