Pasting annotations - is there an event?

[schmoli]

Using viewer 201

I noticed when pasting an annotation from either the same pdf or another, EVERYTHING is pasted, including creation date, modification date, author, and readOnly status. I am about to delve into the documentation looking, but figured it couldn't hurt to throw this question out as I don't see it on first, second, or third glance, but I would like to perhaps change a few things about an annotation when I paste it, specifically the readOnly bit, but perhaps also the author and the creation date.

My reasoning is we lock all annotations at save time, so if a user opens a 'complete' document, and copies a locked annotation (lets say created by someone else entirely), and then goes and loads a new document, and pastes said annotation, it is also read only.

Alternatives I will look into are: not allowing pasting (last resort really), not allowing copying of read-only annotations (I would be ok with this), or just some easy way to trigger when it happens and I can go in and update said annotation(s).

Hi, schmoli.

I can suggest you one solution, not simple but it will work..

Add code to process event about changing the selection.

Code: Select all

pdfViewer.SetProperty("Notifications.Selection.Filter", -1);
....
function OnEvent(Type, Name, DataIn, DataOut, Flags)
{
   if (Type == PXCVA_OnNamedNotify) and 
      (Name == "Notifications.Selection") then
   {
      string annotSelIsReadonly;
      pdfViewer.GetProperty("Notifications.Selection.Document", DataOut, 0);
      int docID = DataOut;
      pdfViewer.DoDocumentVerb(docID, NULL, "GetSelectedAnnot", DataIn, DataOut, 0);
      int pageIndex = DataOut[0];
      if (pageIndex >= 0)
      {
            int annotIndexOnPage = DataOut[1];
            pdfViewer.RunJavaScript("var aa = this.getAnnots(" + pageIndex + "); if (aa.length) aa[" + annotIndexOnPage + "].readOnly;", out annotSelIsReadonly, docID, 0);
      }
      string cmdState = "Online";
      if (annotSelIsReadonly == "true")
            cmdState = "Offline";
      pdfViewer.SetProperty("Commands["Copy"].State", cmdState, 0);
      pdfViewer.SetProperty("Commands["Cut"].State", cmdState, 0);
   }
}

I forgot to reply when I solved this but what I did is examine the annotations before the paste operation, and then again after -- any new annotations I was able to find I update whatever properties I need to change.
