How can I get the page where a page item is localized?

Question

Hi<br /><br />I move some page items to the next spread using kMoveToSpreadCmdBoss. This works fine. But when I want to get the page uid where the page item is localized now (I use Utils<ILayoutUtils>()->GetOwnerPageUID to do that) I get the uid of the spread and not the uid of the page where the page item is localized.<br /><br />- What is wrong?<br />- What can I do to get the page uid?<br /><br />Thanks<br />Hans

Hans,<br /><br />I recently had to do the same, so I'll show you what I have done.  I start by getting the spline item UIDRef and the value that Utils<ILayoutUtils>()->GetOwnerPageUID gives you.  Then I figure out which side of the spread the item falls on:<br /><br />InterfacePtr<IGeometry> splineGeo(ItemRef, IID_IGEOMETRY);<br /><br />PMRect itemRect = splineGeo->GetStrokeBoundingBox();<br /><br />PMPoint currPoint = itemRect.LeftTop();<br /><br />InnerToPasteboard(splineGeo, &currPoint);<br />     <br />if(currPoint.X() < 0){<br />     //it's a left-hand page<br />     left = true;<br />}<br /><br />Once I know which side the item is on, I can calculate which page the item falls on(where OwnerUID is the UID that the call to GetOwnerPageUID returns):<br /><br />UID GetOwningPageUID(IDocument *docPtr, UID OwnerUID, bool left)<br />{<br />        UID rc;<br />     int32 index;<br />     <br />     //get the database <br />     IDataBase *db = ::GetDataBase(docPtr);<br /><br />     //Get the list of pages<br />     InterfacePtr<IPageList> pgList(docPtr, IID_IPAGELIST);<br /><br />     index = pgList->GetPageIndex(OwnerUID);<br /><br />     if(index >= 0){<br />          //the passed in UID refers to a page<br />                rc = OwnerUID;<br />     }else{<br />                //dealing with a spread UID<br />          UIDRef pageSpreadUIDRef(db, OwnerUID);<br /><br />          InterfacePtr<ISpread> pgSpread(pageSpreadUIDRef, UseDefaultIID());<br /><br />          int32 pageCount = pgSpread->GetNumPages();<br /><br />          if(pageCount == 1){<br />               rc = pgSpread->GetNthPageUID(0);<br />          }else if(pageCount <= 2){<br />               if(left){<br />                    rc = pgSpread->GetNthPageUID(0);<br />               }else{<br />                    rc = pgSpread->GetNthPageUID(1);<br />               }<br />          }else{<br />                     rc = nil;<br />          }<br />     }<br /><br />     return rc;<br />}<br /><br />I hope this helps.<br /><br />Dan
