Member Enumeration Documentation

enum MouseMode

Search for all occurrences

In the pointer mode, the cursor behaves in the familiar way and the 'relative motion' values stored in Events are limited by the boundaries of the screen.

In the navigator mode, we warp the position of the pointer as necessary to allow unlimited relative motion, at the expense of a consistent sense of absolute position.

Get a copy of the currently used tonemap parameters or default if missing.

There is no reference in the copy to any currently used parameters, so changing a value in the copy will not have any functional effect. Default implementation just returns the parameters that is set with the default implementation of SetTonemapParameters(const awViewing::PhotographicTonemapData& parameters).
