Thanks for the answer Paolo and Alex, I just skipped the pick() call and use
it via update().
Now it compiles but I dont get any picking feedback, so I must do something
wrong.
I implemented it similar to sample4. All I want is, whenever I receive a
MFC-Message about an left doubleclick within my scene window,
I want to get the according geometry node (actually the dcs node). No
interaction, focus etc.

So here is what I do:

###at Init:
m_pPicker = new pfvMousePicker;
m_pPicker->setNodeDataSlot("PICKER");

m_pPicker->setChannel(channel_);

m_pPicker->setState(PFPICKER_FOCUS_EVENT, NULL, NULL);

###when I insert a new object into the scene:

pSOI = new SceneObjInteractor(); //my own interactor class, mostly the same
as in sample 4

pSOI->node = pDCS; //i dont know if this is redundant according to the next
line

pSOI->nodeSetup(pDCS, m_pPicker);

###then when i receive a left mousebutton dblclick message:

pfvInteractor* piatest;

m_pPicker->update(); //btw i also call m_pPicker->update() every frame

m_pPicker->getPickResults(&piatest);

int id = -1;

if(piatest)

{

    id = (int) ((SceneObjInteractor*)pia)->GetId(); //memberfunction of my
interactor class

}

m_dlgLibrary.SelectSceneObjPerID(id);

and here, even when i am right before a huge object and doubleclick,

m_pPicker->getPickResults(&piatest); always delivers piatest == NULL;

furthermore i have breakpoints in each memberfunction of my interactor
class, except of the cunstructor, none is ever called

what did i miss?

thnx in advance

Denis

P.S. btw there is a typo in pfMousePicker.h in the #ifndef line
