I have a function that when you click a point it draws a path between that clicked point and start point. I do have a checkable button that activates and disables the tool, so I am trying to intergrate that. However, all of this has a major issue: I cannot draw multiple paths without it connecting from the last point of the original one, meaning I get this one infinetly drawable line. No matter me disabling or re-enabling the tool, it still starts from the original first drawn path.

        elif event.button() == Qt.MouseButton.RightButton:
            self.points.append(self.mapToScene(event.pos()))

            if len(self.points) > 1:
                path = QPainterPath()

                path.moveTo(self.points[0])

                for point in self.points[1:]:
                    path.lineTo(point)  # Add line segment to existing path

                # Create and configure CustomPathItem only once (outside loop)
                if not hasattr(self, "path_item"):
                    self.path_item = CustomPathItem(path)
                    self.path_item.setPen(self.pen)
                    if self.button3.isChecked():
                        self.path_item.setBrush(QBrush(QColor(self.stroke_fill_color)))
                    self.path_item.setZValue(0)
                    self.path_item.setFlag(QGraphicsItem.GraphicsItemFlag.ItemIsSelectable)
                    self.path_item.setFlag(QGraphicsItem.GraphicsItemFlag.ItemIsMovable)
                    self.canvas.addItem(self.path_item)

                # Update path of existing item within the loop
                self.path_item.setPath(path)

            super().mousePressEvent(event)

I don’t know if I explained my issue, so if clarification is needed, please ask. Any help is appreciated.
