How to find out which page contains a specific ITextFrame

Question

Hi all,<br /><br />I would like to ask if it is possible to find out which page contains a specific text frame?<br /><br />I used the following code to find the ITextFrame that contains the caret<br />ISelectionManager* mgr = activeContext->GetContextSelection();<br />InterfacePtr<ITextEditSuite> esuite(mgr, UseDefaultIID());<br />InterfacePtr<ITextTrackerAccess> tracker(esuite, UseDefaultIID());<br />ITextFocus* focus = tracker->QueryTextFocus();<br />ITextModel* model = focus->QueryTextModel();<br />IFrameList* flist = model->QueryFrameList();<br />RangeData range = textFocus->GetCurrentRange();<br />TextIndex cposition = range.Start(0);<br />int32 fidx;<br />ITextFrame* frm = flist->QueryFrameContaining(cposition, &fidx);<br />UIDRef frmUIDRef = ::GetUIDRef(frm);<br /><br />However, when I use the following code to iterate through the pages, I cannot find any UID that matches the ITextFrame<br />for (int32 sIdx = 0; sIdx < spreadList->GetSpreadCount(); sIdx++) {<br />  UIDRef spreadUIDRef(database, spreadList->GetNthSpreadUID(sIdx));<br />  InterfacePtr<ISpread> spread(spreadUIDRef, UseDefaultIID());<br />  for (int32 pIdx = 0; pIdx < spread->GetNumPages(); pIdx++) {<br />    spread->GetItemsOnPage(pageIndex, &uidList);<br />    if (uidList.Contains(frmUIDRef.GetUID()) == kTrue) {<br />      ...<br />    }<br />  }<br />}<br /><br />Any help is appreciate. Thank you.<br /><br />Ikki

I think your frmUIDRef is too far down the hierarchy to show up in GetItemsOnPage(). Try getting the IHierarchy interface from frmUIDRef and calling QueryParent(). That should get you from the kFrameItemBoss to the kMultiColumnItemBoss. Do the same again and you'll get to the kSplineItemBoss, which should appear in GetItemsOnPage().
If you're running the debug version of InDesign, you can use the Test menu to run the Diagnostics > Document Structure > Trace Content Hierarchy command, which will print out the UIDs of all the items on a page and let you see what's happening.
