Ik this a late response for you and you already found a solution for text widgets, but for anyone else who’s ending up here by following various tutorials, you shouldn’t modify your widgets directly with a setter. Instead, look for methods for modifying the values that you need to change. For instance, the method/node for setting an image in an image widget is called “Set Brush from Texture”. It’s not as intuitive as getters and setters but it’s what you’re supposed to do as far as I can tell.
