comparison Framework/Scene2DViewport/OneGesturePointerTracker.h @ 700:059e1fd05fd6 refactor-viewport-controller
Introduced the ViewportController that sits between the application and the
Scene2D to handle the trackers and measuring tools. This is a work in progress.
The Scene2D is no longer an observable. Message sending is managed by the
ViewportController.
Move some refs to shared and weak to prevent lifetime issues.

28 This base is class allows to write simple trackers that deal with single | |

30 mouse operations need to be handled. | |
31 | |
32 In order to write such a tracker: | |
33 - subclass this class | |
34 - you may store the initial click/touch position in the constructor | |
35 - implement PointerMove to react to pointer/touch events | |
36 - implement Cancel to restore the state at initial tracker creation time | |
