Adding a text element to a diagram

[Fabio Riera]

It seems a simple task. How I add a text note to a diagram from my add-in? I found a collection called "Diagram.DiagramObjects", but I can't add a new element there.

Thanks in advance.

Hi Fabio,

the following snippet shows you how to add a note, connect to an element and visualize the note of the element.

Code: [Select]

                       Repository.SaveDiagram(dia.DiagramID);
                      
                       EA.Element elNote = null;
                       try
                       {
                           elNote = (EA.Element)pkg.Elements.AddNew("", "Note");
                           elNote.Update();
                           pkg.Update();
                       }
                       catch { break; }

                       // add element to diagram
                       // "l=200;r=400;t=200;b=600;"

                       // get the position of the Element
                       EA.DiagramObject diaObj = null;
                       foreach (EA.DiagramObject dObj in dia.DiagramObjects) {
                           if (dObj.ElementID == el.ElementID)
                           {
                               diaObj = dObj;
                               break;
                           }
                       }
                          int left = diaObj.left + 2*(diaObj.right - diaObj.left);
                       int right = diaObj.right + 2 * (diaObj.right - diaObj.left);

                       string position = "l=" + left.ToString() +";r=" + right.ToString() + ";t=" + diaObj.top.ToString() + ";b=" + diaObj.bottom.ToString() + ";";
                       EA.DiagramObject diaObject = (EA.DiagramObject)dia.DiagramObjects.AddNew(position, "");
                       dia.Update();
                       diaObject.ElementID = elNote.ElementID;
                       diaObject.Update();
                       pkg.Elements.Refresh();
                       // make a connector
                       EA.Connector con = (EA.Connector)el.Connectors.AddNew("test", "NoteLink");
                       con.SupplierID = elNote.ElementID;
                       con.Update();
                       el.Connectors.Refresh();
                       Util.setElementHasAttchaedLink(Repository, el, elNote);
                       Repository.ReloadDiagram(dia.DiagramID);

                   }

Thanks! Text added successfully!
Is there a document that lists which html tags are allowed in the .Notes property of an Element?

Use Repository.GetFormatFromField and it's pendant.

Yes, don't try to do EA notes formatting yourself, but use use either HTML or RTF to do formatting and let EA convert it to it's own format using the GetFormatFromField and GetFieldFromFormat operations.
