PyQt6 spacing/border issue

Captain Haddock

PyQt6 .. how do I get the QLabel to appear in the upper right without any spacing or border that appears when running the code below:

import sys

from PyQt6 import QtWidgets, QtCore, QtGui
from PyQt6.QtWidgets import QApplication, QMainWindow


class Main(QMainWindow):
    def __init__(self, parent=None):
        super(Main, self).__init__(parent)

        self.setupUI(self)

    def setupUI(self, Main):

        Main.setObjectName("Main")
        Main.resize(800, 480)
        Main.setStyleSheet("background: blue")

        frame = QtWidgets.QWidget(self)
        frame.setStyleSheet("background-color:green")
        frame.setFixedHeight(100)
        self.setCentralWidget(frame)

        layout = QtWidgets.QHBoxLayout()
        layout.setSpacing(0)
        frame.setLayout(layout)

        label = QtWidgets.QLabel()
        label.setObjectName("label")
        label.setStyleSheet("background: red")
        label.setMinimumSize(1, 1)
        label.setAlignment(QtCore.Qt.AlignmentFlag.AlignCenter)
        label.setFixedWidth(100)
        label.setFixedHeight(100)

        layout.addStretch(True)
        layout.addWidget(label)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    showMain = Main()
    showMain.show()
    sys.exit(app.exec())

add:
layout.setContentsMargins(0,0,0,0)
