| 42 /* A note on why the polling loops are necessary. | |
| 43 The BeOS Preview 2 implementation of BView->MouseMoved() only notifies | |
| 44 the view when the mouse enters or leaves the view. The documentation | |
| 45 says that you should loop and use GetMouse() to detect mouse motion. | |
| 46 The BeOS Preview 2 implementation of BView->KeyDown() and BView->KeyUp() | |
| 47 are only called for keys that generate ASCII characters. Since we want | |
| 48 to act like a low level raw keyboard, we need to poll the state of the | |
| 49 keys instead of catching the keys in callbacks. | |
| 50 These are documented portions of the BeBook for Preview Release 2 | |
