Detailed Description

Manager of the QVR application's control flow and its processes and windows.

The QVRManager object is typically created right after the QApplication object. Afterwards, the application typically sets its preferred OpenGL context properties, and then initializes the QVRManager object:

QApplication app(argc, argv);
QVRManager manager(argc, argv);
// Set OpenGL context properties:
QSurfaceFormat format;
format.setProfile(QSurfaceFormat::CoreProfile);
format.setVersion(3, 3);
QSurfaceFormat::setDefaultFormat(format);
// Start the QVR application
MyQVRApp myqvrapp;
if (!manager.init(&myqvrapp))
    return 1;
return app.exec();

Constructor & Destructor Documentation

◆ QVRManager()

QVRManager::QVRManager	(	int &	argc,
		char *	argv[]
	)

This constructor creates the manager object.

The following command line options are intereted by the QVR manager and removed from argc and argv:

--qvr-config=<config.qvr>
Specify a QVR configuration file.
--qvr-timeout=<msecs>
Set a timeout value in milliseconds for all interprocess communication. The default is -1, which means to never timeout.
--qvr-log-level=<level>
See QVRLogLevel.
--qvr-log-file=<filename>
Write all log messages to the given file instead of the standard error stream.
--qvr-sync-to-vblank=<0|1>
Disable (0) or enable (1) sync-to-vblank. This overrides the per-process setting in the configuration file.
--qvr-fps=<n>
Make QVR report frames per second measurements every n milliseconds.
--qvr-autodetect=<list>
Comma-separated list of VR hardware that QVR should attempt to detect automatically. Currently supported keywords are 'all' for all hardware, 'oculus' for Oculus Rift, 'openvr' for OpenVR hardware, 'googlevr' for Google VR hardware, 'gamepads' for gamepads. Each entry can be preceded with '~' to negate it. For example, use '--qvr-autodetect=all,~oculus' to try autodetection for all hardware except Oculus Rift. This option only takes effect if no --qvr-config option was given.

This function will create all child processes and all windows, depending on the QVR configuration, and it will call the initialization functions of app.

Applications that implement their own navigation methods in QVRApp::update() should set the preferCustomNavigation flag.
