they are written to disk, either inline or as an external file. Added support for
this in the .ive plugin. Default of WriteHint is NO_PREFERNCE, in which case it's
up to the reader/writer to decide.
when applying styles to a Label element the code below runs in a infinite loop.
The reason for this is that nothing increments the Reader "r" in the case when applying a style to label,
so I advance the reader when no match was found.
( To replicate the error apply style to any label)
replaced this:
while(!r.eof()) if(_styles[style]->applyStyle(t, r)) inc = true;
with this:
while(!r.eof())
{
if(_styles[style]->applyStyle(t, r))
inc = true;
else
r.advanceOverCurrentFieldOrBlock();
}
I tested it and it works well for me, I did not find any problems with it.
2. Added style support for Canvas element, event though there is no styles to apply yet.
It is usefull for someone who inherits from Canvas class to develop another element.
If applyStyle(Canvas) does not exist
there is no way to apply style to the element that inherited from Canvas element.
Added virtual
bool applyStyle(Canvas).
and in added call to apply style if the Object is of type Canvas:
StyleManager::_applyStyleToObject(osg::Object* obj, const std::string& style) {
...
else if(!std::string("Canvas").compare(c))
return _coerceAndApply<Canvas>(obj,style,c);

"I made several modifications:
* The cause of my errors was that my OSG source directory path contains spaces. To fix this issue I wrapped all paths with quotes, as stated in doxygen documentation.
* I also received some warning messages about deprecated doxygen settings, which I fixed by updating the doxygen file, i.e. running \u2018doxygen \u2013u doxygen.cmake\u2018. By running this command deprecated doxygen options are removed, some option comments have changed and quite some options have been added (I kept their default settings unless mentioned).
* I was surprised to find that the doxygen OUTPUT_DIRECTORY was set to \u201c${OpenSceneGraph_SOURCE_DIR}/doc\u201d, which does not seem appropriate for out of source builds; I changed this to \u201c${OpenSceneGraph_BINARY_DIR}/doc\u201d. (On the other hand, maybe a cmake selectable option should be given to the user?)
* Fixed two warnings I received about unexpected end-of-list-markers in \u2018osg\AnimationPath and \u2018osgUtil\CullVisitor due to excess trailing points in comments.
* Fixed a warning in osgWidget\StyleInterface due to an #include directive (strangely) placed inside a namespace.
* Fixed a warning in osg\Camera due to the META_Object macro that confused doxygen. Adding a semi-colon fixed this.
* Removed auto_Mainpage from the INCLUDE option, because I am positive that this file does not belong there; It never generated useful documentation anyway.
* I added the OSG version number environment variable to the PROJECT_NUMBER option so that the version number is now shown on the main page of generated documentation (e.g. index.html).
* Changed option FULL_PATH_NAMES to YES, but made sure STRIP_FROM_PATH stripped the absolute path until the include dir. This fixed an issue that created mangled names for identical filenames in different directories. E.g. osg/Export and osgDB/Export are now correctly named.
* Changed option SHOW_DIRECTORIES to yes, which is a case of preference I guess.

New attribute DatabasePager::_expiryFrames sets number of frames a PagedLOD child is kept in memory. The attribute is set with DatabasePager::setExpiryFrames method or OSG_EXPIRY_FRAMES environmental variable.
New attribute PagedLOD::PerRangeData::_
frameNumber contains frame number of last cull traversal.
Children of PagedLOD are expired when time _AND_ number of frames since last cull traversal exceed OSG_EXPIRY_DELAY _AND_ OSG_EXPIRY_FRAMES respectively. By default OSG_EXPIRY_FRAMES = 1 which means that nodes from last cull/rendering
traversal will not be expired even if last cull time exceeds OSG_EXPIRY_DELAY. Setting OSG_EXPIRY_FRAMES = 0 revokes previous behaviour of PagedLOD.
Setting OSG_EXPIRY_FRAMES > 0 fixes problems of children reloading in lazy rendering applications. Required behaviour is achieved by manipulating OSG_EXPIRY_DELAY and OSG_EXPIRY_FRAMES together.
Two interface changes are made:
DatabasePager::updateSceneGraph(double currentFrameTime) is replaced by DatabasePager::updateSceneGraph(const osg::FrameStamp &frameStamp). The previous method is in #if 0 clause in the header file. Robert, decide if You want to include it.
PagedLOD::removeExpiredChildren(double expiryTime, NodeList &removedChildren) is deprecated (warning is printed), when subclassing use PagedLOD::removeExpiredChildren(double expiryTime, int expiryFrame, NodeList &removedChildren) instead. "
viewer.addEventHandler(new osgViewer::ScreenCaptureHandler(
new osgViewer::WriteToFileCaptureOperation("filename", "jpg")));
and the filename will be what you want. The WriteToFileCaptureOperation will add the context ID and the file number (if in SEQUENTIAL_NUMBER mode) to the file name.
(The attached also clarifies some notify messages, and corrects the comment when adding the handler in osgviewer.cpp)
I also remembered, the current architecture could allow a different CaptureOperation for each context, but currently the API only allows setting one CaptureOperation for all contexts. This could be improved if need be.

it was just handling static state.
implementation of the atomic increment and decrement into a implementation
file.
This way inlining and compiler optimization can no longer happen for these
implementations, but it fixes compilation on win32 msvc targets. I expect
that this is still faster than with with mutexes.
Also the i386 gcc target gets atomic operations with this patch. By using an
implementation file we can guarantee that we have the right compiler flags
available."
