Some help with cast to QPointer wished for.
Message 1 in thread
Hi List
I have a definition like this:
QPointer<svNodeChain*> hostChain; in a class named svNode
And I try to assign to this in another class like so:
void* temp = this;
nodens->hostChain = temp;
Where nodens is of type svNode* and hostChain is as above
but I keep getting errors of this kind:
Error 1 error C2679: binary '=' : no operator found which takes a right-hand operand of type 'void *' (or there is no acceptable conversion) c:\RAS\ver_0.1\Ras_Application\svNodeChain.cpp 48
I have tried const_cast<svNodeChain> and reinterpret_cast<svNodeChain*> and a lot of old c hacks but I cant seem to make
the compiler accept that one pointe just should be treated as another kind of pointer. Do anyone spot the error ?

Yes I am aware of that and svNodeChain does inherit QObject.

Take a look into the docs: No need to specify the type as pointer,
QPointer<svNodeChain> should do. If that doesn't help: What about
qobject_cast? Or declaring temp with the correct type right away?
