void osgViewer::ViewerBase::addUpdateOperation | ( | osg::Operation * | operation | ) |
Add an update operation.

|

Return true if viewer threads are running.

pure virtual |
check to see if the new frame is required, called by run(..) when FrameScheme is set to ON_DEMAND.
Implemented in osgViewer::CompositeViewer, and osgViewer::Viewer.
void osgViewer::ViewerBase::checkWindowStatus | ( | ) |
Check to see if any windows are still open. If not, set viewer done to true.
void osgViewer::ViewerBase::checkWindowStatus | ( | const Contexts & | contexts | ) |
Check to see if windows are still open using the list of contexts given as a parameter. If no windows are open, stop rendering threads and set viewer done to true. This function is more effective than checkWindowStatus() as it does not query the context list and should be used whenever context list is already available in your code.
|
inline |
Return true if viewer's work is done and should exit the frame loop.

void osgViewer::ViewerBase::removeUpdateOperation | ( | osg::Operation * | operation | ) |
Remove an update operation.
|
virtual |
|
virtual |
Execute a main frame loop. Equivalent 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.
Reimplemented in osgViewer::CompositeViewer, and osgViewer::Viewer.
|
inline |
Set the done flag to signal the viewer's work is done and should exit the frame loop.
void osgViewer::ViewerBase::setEndBarrierPosition | ( | BarrierPosition | bp | ) |
Set the position of the end barrier. AfterSwapBuffers may result in slightly higher framerates, but may lead to inconsistent 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.
|
inline |
Set the EventVisitor.
void osgViewer::ViewerBase::setIncrementalCompileOperation | ( | osgUtil::IncrementalCompileOperation * | ico | ) |
Set the incremental compile operation. Used to manage the OpenGL object compilation and merging of subgraphs in a way that avoids overloading the rendering of frame with too many new objects in one frame.
|
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.
|
inline |
if the flag is true, the viewer set its done flag when a QUIT_APPLICATION is received, false disables this feature
|
inline |
Set the graphics operation to call on realization of the viewers graphics windows.
|
inline |
Hint to tell the renderingTraversals() method whether to call relaseContext() on the last context that was made current by the thread calling renderingTraverals(). Note, when running multi-threaded viewer no threads will be made current or release current. Setting this hint to false can enable the frame loop to be lazy about calling makeCurrent and releaseContext on each new frame, helping performance. However, if you frame loop is managing multiple graphics context all from the main frame thread then this hint must be left on, otherwise the wrong context could be left active, introducing errors in rendering.
