from PySide2.QtWidgets import *


def addButton(layout):
    box = QCheckBox("Hi h !")
    layout.addWidget(box)


if __name__ == '__main__':
    app = QApplication(sys.argv)

    widget = QWidget()
    lay = QGridLayout()
    widget.setLayout(lay)
    btn = QPushButton("Press me")
    lay.addWidget(btn)
    btn.released.connect(lambda: addButton(lay))
    widget.show()

    sys.exit(app.exec_())
