So I have been trying to make a custom oval shape using QGraphicsEllipseItem.

Upon reading the Qt's official documentation regarding QGraphicsEllipseItem, I didn't seem to find out how to manage it.

Here is the custom oval shape:

If you want to implement complex shapes then a possible solution is to use QPainterPathItem:

from PyQt5.QtCore import QRectF
from PyQt5.QtGui import QColor, QPainterPath
from PyQt5.QtWidgets import (
    QApplication,
    QGraphicsPathItem,
    QGraphicsScene,
    QGraphicsView,
)


def main():
    app = QApplication([])

    radius = 20
    length = 100

    square = QRectF(0, 0, 2 * radius, 2 * radius)

    path = QPainterPath()
    path.moveTo(radius, 0)
    path.arcTo(square, 90, 180)
    path.lineTo(length, 2 * radius)
    square.moveRight(length + 2 * radius)
    path.arcTo(square, -90, 180)
    path.lineTo(radius, 0)

    item = QGraphicsPathItem()
    item.setBrush(QColor("red"))
    item.setPen(QColor("green"))
    item.setPath(path)

    scene = QGraphicsScene()
    view = QGraphicsView(scene)
    scene.addItem(item)
    view.show()

    app.exec_()


main()
