How to react to annotation selection on Control

[khho]

Hello Support,
I want to react to the selection of an annotation in the control.

How can I do this?
I don't find an a suitable event to react to in OnEvent method (I only found e.stampSelected).

Maybe there is a way to do this writing a EventListener? On what? What would be the UIX_EventCode?

Kind regards

You may try to handle the e.docSelection.changed. Then:

Code: Select all

int id_e_docSelection_changed = Str2ID("e.docSelection.changed");
int id_selection_annots = Str2ID("selection.annots");
....
OnEvent(eventID, event, from)
{
      if (eventID == id_e_docSelection_changed)
      {
           selEvent = (IPXV_DocSelChangedEvent)event;
           if (selEvent != null)
           {
                 if (selEvent.Selection[id_selection_annots]) 
                 {
                      doc = (IPXV_Document)from;
                      if (doc != null)
                      {
                           annotSel = (IPXV_AnnotSelection)doc.GetSel(id_selection_annots);
                           ...     
                      }
                 }
           }
      }
}

Thank you for this answer.
Unfortunately IPXV_DocSelChangedEvent does not exist at design time in the Interop.PDFXEdit.dll that I use (though it is there at runtime) and to change version might lead to other problems

Is there an alternative way?

I checked this, for example, in our FullDemo app, and it seems everything looks good with that. Just used the PDFXEdit.IPXV_DocSelChangedEvent type there...

But anyway, at the moment, you may simplify the code above by removing using that type. It should work without it too:

Code: Select all

if (eventID == id_e_docSelection_changed)
{                      
       doc = (IPXV_Document)from;
       if (doc != null)
       {
             annotSel = (IPXV_AnnotSelection)doc.GetSel(id_selection_annots);
             ...     
       }
}

HTH.
