    public class QNoNativeResourcesException

extends java.lang.RuntimeException

The QNoNativeResourceException is used to indicate that the C++ native resources of a Java object are destroyed while it is still referenced in Java.

Most Qt Jambi objects consist of a C++ part, i.e., native C++ resources, and a Java peer that wraps the public functions of the native objects. In most cases one can rely on the Java memory model and let objects be garbage collected, in which case this kind of exception will never occur (the garbage collector will only collect unreferenced memory in Java).

In some cases, the ownership of an object is transferred to C++, for instance, when QObjects are passed a parent or items are added to a QGraphicsScene. In these cases the C++ part of the object can be deleted explicitly by, for instance, using the C++ "delete" keyword. When the C++ part of the object has been deleted it can no longer be used and this exception is thrown.

It is possible to check if an object has a valid C++ part or not by checking that the value of nativeId() is non-null.
