Well, the reason is simple: I've a preview class which takes an OSG node, attaches it to a manager and renders once. The node has then to be removed from the previewGraph. To accomplish this the refcount of the node has to be incremented before removing it.
The result is that the node has refcount zero when passing it to the preview class and returns with refcount one. Side effect: if attached to another root refount becomes 2 and is never deleted (when root is deleted). I've to subref the previewed node once added again to the root node. This is dirty and not code clear... I'll find a solution... thanks anyway, Josef On Thu, Jun 26, 2008 at 4:00 PM, Carsten Neumann <[EMAIL PROTECTED]> wrote: > Hello Josef, > > Josef Grunig wrote: >> Hi, >> >> Is it possible to set the refcount of a Node to zero without letting >> OpenSG to destroy it. > > there is only an interface to increment/decrement the ref count, not to > set its value and subRef will always destroy the container if the ref > count becomes <= 0. > Since in 1.x ref counting is basically done manually, you can create a > Node and keep it with a ref count of zero, but only if you don't make it > another Node's child. > However, all this is quite hacky and relies on knowledge of > implementation details.
