Please, how is it possible to add symbol to score via plugin?

I tried following, but it is not working.
What I am doing wrong please?
Thank You.

var sym = newElement(Element.SYMBOL);
sym.symbol = "noteheadSlashDiamondWhite";
cursor.add(sym);

Thanks, but it still doesnt work.
Here is comlete snippet.

import QtQuick 2.0
import MuseScore 3.0
 
MuseScore {
      version:  "3.0"
      description: "This demo plugin creates a new score."
      menuPath: "Plugins.createscore"
      requiresScore: false
 
      onRun: {
            var sel = curScore.selection;
            var cursor = curScore.newCursor();
            cursor.rewind(0);
            cursor.track = 0;
            var text = newElement(Element.SYSTEM_TEXT);
            text.text = "text";
            var sym = newElement(Element.SYMBOL);
            sym.symbol = "<sym>noteheadSlashDiamondWhite</sym>";
            cursor.add(text); // works
            cursor.add(sym); //doesnt work
            Qt.quit();
            }
      }

I'm not sure you can add symbols that way.
You can add staff text however, and set the text property to the symbol you want enclosed in sym tags

Thanks, it seems to be usable workround at the moment.

Does it mean, it is not possible to create symbols via plugin?

Here are few examples (made in Musescore, not by plugin).
First symbol is assigned to staff (this can be probably hacked by staff text).
Scond is assigned to note. Can be this done somehow?

Thanx.

The issue seems to be that you are trying to add a symbol to a rest while a cursor assumes that symbols should be added only to notes. So if you position a cursor to a note before adding the symbol then your code should work fine. In UI you can add a symbol to a rest so this is apparently something that was missed when adding that functionality to a cursor, but otherwise creating symbols is possible with plugins.

So this code change:

diff --git a/mscore/plugin/api/cursor.cpp b/mscore/plugin/api/cursor.cpp

-                  // To be added to a note
-                  case ElementType::SYMBOL:
+                  // To be added to a note (and in case of SYMBOL also to a rest)
+                  case ElementType::SYMBOL: {

+                        if (curElement->isRest()) {
+                              s->setParent(curElement);
+                              _score->undoAddElement(s);
+                              }

                   case ElementType::FINGERING:
                   case ElementType::BEND:
                   case ElementType::NOTEHEAD: {

should fix this, shoudn't it?

See https://github.com/musescore/MuseScore/pull/7868 (for 3.x, check the artifacts to test)
and https://github.com/musescore/MuseScore/pull/7869 (for master)

Edit: both have been merged, so should be found in the development builds at https://musescore.org/en/download#Development-builds shortly

Thanks, for this.
But UI allows to add symbols to segment too (if it is not a bug), like staff text.

So, in case, it is not a bug, may be, question, if it wouldn't be better to cursor add it to segment.

And note.add(symbol) would add it to note (it does, in fact).
