Mouse Control Modes

The value returned by the QTVRGetCurrentMouseMode function is an unsigned long integer that encodes the current mouse control modes. If a bit in the integer is set, the corresponding mode is one of the current mouse modes. The mode bits are addressed using these constants:

enum {
    kQTVRPanning                                    = 1L << 0,
    kQTVRTranslating                                = 1L << 1,
    kQTVRZooming                                    = 1L << 2,
    kQTVRScrolling                                  = 1L << 3,
    kQTVRSelecting                                  = 1L << 4
};

Notice that several modes can be returned, not just the highest priority one. That means a return value could have both zooming and translating set, for example.

Constant descriptions

kQTVRPanning
If this bit is set, the mouse controls panning of standard objects, using objects-only controllers.
kQTVRTranslating
If this bit is set, the mouse controls translation for all objects.
kQTVRZooming
If this bit is set, the the mouse controls zooming for all objects.
