Получаю ошибку:

AttributeError: 'Ui_Form' object has no attribute 'grab'

Мой код:
file.py:

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(522, 185)
        self.pushButton = QtWidgets.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(20, 100, 481, 71))
        self.pushButton.setObjectName("pushButton")
        self.lineEdit = QtWidgets.QLineEdit(Form)
        self.lineEdit.setGeometry(QtCore.QRect(20, 20, 481, 71))
        self.lineEdit.setObjectName("lineEdit")

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.pushButton.setText(_translate("Form", "Screenshot"))

main.py:

from PyQt5 import QtCore, QtGui, QtWidgets, uic
import sys
from file import Ui_Form
import os

app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()

def buttonHandler(self):
        ui.grab().save('save.png', 'png')
        os.startfile('image.png')
        print('END')

ui.pushButton.clicked.connect( buttonHandler )

sys.exit(app.exec_())

Александр, Спасибо! Нашёл решение!

def buttonHandler():
	Form.grab().save('save.png', 'png')

[Александр]

Вы сами нашли решение, что надо использовать метод grab объекта widget?
