Hi,
unfortunately now I found an unexpected behavior with the non-osgFX solution.
Pushing wireframe button on and off quite fast from my application I get
sometimes a crash, sometimes the surface disappears and I can see just the
wireframe (there's no way to get the surface visible again). OSG 3.1.4 are used
in this case.
The crash happens at the end of this piece of code (osg/State):
Code:
inline bool applyAttribute(const StateAttribute*
attribute,AttributeStack& as)
{
if (as.last_applied_attribute != attribute)
{
if (!as.global_default_attribute.valid())
as.global_default_attribute =
dynamic_cast<StateAttribute*>(attribute->cloneType());
as.last_applied_attribute = attribute;
attribute->apply(*this);
And here is the call stack:
Code:

attribute, osg::State::AttributeStack & as) Line 1596 + 0xe bytes C++
