C Specification

The XrEventDataVisibilityMaskChangedKHR structure specifies an event which indicates that a given view mask has changed. The application should respond to the event by calling xrGetVisibilityMaskKHR to retrieve the updated mask. This event is per-view, so if the masks for multiple views in a configuration change then multiple instances of this event will be sent to the application, one per view.

typedef struct XrEventDataVisibilityMaskChangedKHR {
    XrStructureType            type;
    const void*                next;
    XrSession                  session;
    XrViewConfigurationType    viewConfigurationType;
    uint32_t                   viewIndex;
} XrEventDataVisibilityMaskChangedKHR;


Member Descriptions
  • type is the XrStructureType of this structure.

  • viewConfigurationType is the view configuration whose mask has changed.

  • viewIndex is the individual view within the view configuration to which the change refers.
