Revit API : "PickObject" not displaying dialog window
Question: I just did what is written
[here](http://stackoverflow.com/questions/21296317/revit-python-pick-object-
select-object), but I got a problem with `__window__.Topmost = True`.

(So, I'm running directly from the Shell)

Here is my complete code :

    
    
    def Test(self) :
       __window__.Hide()
       sel = __revit__.ActiveUIDocument.Selection
       pickedRef = sel.PickObject(ObjectType.Element, "Please select a group");
       __window__.Show()
       __window__.Topmost = True
       return pickedRef
    

Indeed, if I do that, I got an error message saying that 'return' is outside
function. If I change the 'return' line with something else, like `elem =
Element.GetGeometryObjectFromReference(pickedRef)`, then it says that there is
an unexpected indent (of course I checked indentation, should be ok normally).

Finally, if I comment the `__window__.Topmost` line, then I got no error
message.

Do you also experience problems with that ?

But then my biggest issue is that in the end, I get to select an element, but
I see no dialog window popping up with the expected message "please select a
group"). Where does that come from ? I guess the "topmost" command just brings
back the shell on top, so it doesn't come from that...

Any clue ?

Thanks a lot !


Answer: I answered to your comment in french on my website :

PickObject Method is not supposed to make any window popping up. It shows an
help message at bottom left corner, check this image : ! [Revit extract with
message](http://pythoncvc.net/wordpress/wp-

Here is a working code :

    
    
    def pickobject():
        from Autodesk.Revit.UI.Selection import ObjectType
        __window__.Hide()
        picked = uidoc.Selection.PickObject(ObjectType.Element, "Select object")
        __window__.Show()
        __window__.Topmost = True
        return picked
    

Moreover, you are not supposed to add "self" in this context. It will return
the following error : Traceback (most recent call last): File "", line 1, in
TypeError: pickobject() takes exactly 1 argument (0 given)
