const

Get whether at least of one of this viewers windows are realized.

void osgViewer::CompositeViewer::realize

void osgViewer::CompositeViewer::setThreadingModel

(

ThreadingModel

threadingModel

)

Set the threading model the rendering traversals will use.

ThreadingModel osgViewer::CompositeViewer::getThreadingModel

(

)

const [inline]

Get the threading model the rendering traversals will use.

void osgViewer::CompositeViewer::setEndBarrierPosition

(

BarrierPosition

bp

)

Set the position of the end barrier. AfterSwapBuffers will may result is slightly higher framerates, by may lead to inconcistent swapping between different windows. BeforeSwapBuffers may lead to slightly lower framerate, but improve consistency in timing of swap buffers, especially important if you are likely to consistently break frame.

BarrierPosition osgViewer::CompositeViewer::getEndBarrierPosition

(

)

const [inline]

Get the end barrier position.

void osgViewer::CompositeViewer::setEventQueue

(

osgGA::EventQueue *

eventQueue

)

[inline]

(

)

[inline]

const osgGA::EventQueue* osgViewer::CompositeViewer::getEventQueue

(

)

const [inline]

void osgViewer::CompositeViewer::setKeyEventSetsDone

(

int

key

)

[inline]

Set the key event that the viewer checks on each frame to see if the viewer's done flag should be set to signal end of viewers main loop. Default value is Escape (osgGA::GUIEVentAdapter::KEY_Escape). Setting to 0 switches off the feature.

int osgViewer::CompositeViewer::getKeyEventSetsDone

(

)

const [inline]

get the key event that the viewer checks on each frame to see if the viewer's done flag.

void osgViewer::CompositeViewer::setQuitEventSetsDone

(

bool

flag

)

[inline]

if the flag is true, the viewer set its done flag when a QUIT_APPLICATION is received, false disables this feature

bool osgViewer::CompositeViewer::getQuitEventSetsDone

(

)

const [inline]

Returns:

true if the viewer respond to the QUIT_APPLICATION-event

virtual int osgViewer::CompositeViewer::run

(

)

[virtual]

Execute a main frame loop. Equivialant to while (!viewer.done()) viewer.frame(); Also calls realize() if the viewer is not already realized, and installs trackball manipulator if one is not already assigned.

virtual void osgViewer::CompositeViewer::frame

(

double

simulationTime = USE_REFERENCE_TIME

)

[virtual]

Render a complete new frame. Calls advance(), eventTraversal(), updateTraversal(), renderingTraversals().

		bool	onlyValid = true
	)

void osgViewer::CompositeViewer::setRealizeOperation

(

osg::Operation *

op

)

[inline]

Set the graphics operation to call on realization of the viewers graphics windows.

osg::Operation* osgViewer::CompositeViewer::getRealizeOperation

(

)

[inline]

Get the graphics operation to call on realization of the viewers graphics windows.

bool osgViewer::CompositeViewer::areThreadsRunning

(
