multiple GraphicsWindows, this singleton is accessable via GUIEventEvent::getAccumulatedEventState().
Added use of this new singleton in GraphicsWindow* implementations.
Added WindowSizeHandler to osgkeyboard to help with debugging of event state
between windows.
Created a new GraphicsThread subclass from OperationThread which allows the
GraphicsContext specific calls to be moved out of the base OperationThread class.
Updated the rest of the OSG to respect these changes.
completed the new registration of the plugin-readerwriters
("REGISTER_OSGPLUGIN") according to your osgstaticviewer-example (see
attachment, based on today's svn)."
Added and cleaned up DeleteHandler calls in osgViewer to help avoid crashes on exit.
Changed DatabasePager across to dynamically checcking osg::getCompileContext(..)
Updated wrappers.
The current code takes the mouse cursor position and adds it to the
window (left,top) position, and sends the mouse cursor there. But this
doesn't take into account the window decoration.
The new code converts the given (x,y) coordinates from the client area
coordinate system to the screen instead using ClientToScreen. I think
this is the natural windows way to do it.
Tested on XP with osgviewer
"
Note from Robet Osfield, made a few changes to layout to make it more consistent
with the rest of the OSG and used #if 0 instead if (0) blocks.

Found in the join file the fix for the bug found by Rafa.
Problem :
osgIntrospection::Value grp(new osg::Group);
osgIntrospection::ValueList vlcall;
vlcall.push_back(osgIntrospection::Value("toto"));
const osgIntrospection::MethodInfo *m =
grp->getType.getCompatibleMethod("setName", vlcall, true);
if (m)
{
m->invoke(grp, vlcall); // ** SEGFAULT here
}
Algorithm explanation :
The "invoke" method try to convert "grp", which reflect an
"osg::Group*", in a
"osgIntrospection::Value", which reflect a "osg::Node*".
This because
the "setName(const char *)" method found by
"grp->getType.getCompatibleMethod"
is an "osg::Object" type method.
When osgIntrospection do this conversion it try :
- to found a "osgIntrospection::Converter" to convert
from "osg::Group*" to "osg::Node*"
- to found a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
- to converte an Enum to int or unsigned int
- to convert the value in its "value string representation",
then converte this string in the destination value
Else it throw a "TypeConversionException".
Bug :
1)
When osgIntrospection try to found a chain of
"osgIntrospection::Converter"
It could do any downcast or (Type to SuperType) or upcast
(SuperType to Type).
This mean the the chain could be :
osg::Group to osg::Transform to osg::Camera to
osg::CullSettings to osg::CullStack to
osg::CollectOccludersVisitor to
osg::NodeVisitor to osg::Referenced to osg::Object
During the convertion with this chain, A METTRE failed and
the pointer in
"grp" is set NULL. But the "grp" is always a valid
"osgIntrospection::Value"
and so, osgIntrospection accept the conversion. Then it try
to use this pointer
to call the "setName" function. And Bing SEGFAULT.
2)
In "bool Reflection::accum_conv_path( ... )"
the convection path isn't accumulate in the recursive loop.
this cause multi request of a conversion path, and a
slowdown in the
conversion algorithm.
3)
Use of the last conversion way in a conversion from
pointer to pointer
this mean you can do this :
"osg::Node*" to " value string representation" to "osg::Material*"
What a bad thing !!!
Solution :
1)
Introduce the concept of dynamic_cast and static_cast.
now, to do a conversion, osgIntrospection does this :
- to found a "osgIntrospection::Converter" to convert
from "osg::Group*" to "osg::Node*"
- to found a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
only with static_cast, downcast (Type to SuperType)
- to found, if the source and the destination are two pointer,
a chain of "osgIntrospection::Converter" to convert
from "osg::Group*" to "one or many type" to "osg::Node*"
only with dynamic_cast, upcast (SuperType to Type)
- to convert an Enum to int or to unsigned int
- to convert the value in its "value string representation",
then convert this string in the destination value
Else it throw a "TypeConversionException".
Add the "enum CastType" to distinguish the static_cast or
dynamic_cast converter.
Add file OpenSceneGraph/include/osgIntrospection/CastType
2)
add a line to accumulate converter in converter Path.
3)
add a line to check if source and destination are pointer.

COLLADA modules STLDatabase, LIBXMLPlugin and stdErrPlugin are
statically included in the main COLLADA library on Linux and shouldn't
be linked separately - those libraries do not exist in the default Linux
build and the compilation will fail.
Second issue - the current version of the COLLADA plugin (both current
HEAD in Subversion and the one in stable 2.0) do not work right with the
stable COLLADA DOM 1.4.1. I am getting the following error:
