PyQt5 Отследить изменение размера окна?

Question

[MrZed]

Как отследить изменение размера окна?
Нашёл код тут:

import sys
from PyQt5 import QtCore, QtGui
from PyQt5.QtWidgets import QApplication, QMainWindow


class Window(QMainWindow):
    
    resized = QtCore.pyqtSignal()   # 1
    
    def __init__(self):
        super(Window, self).__init__()

        self.resized.connect(self.someFunction)   # 2
        
    def resizeEvent(self, event):
        self.resized.emit()
        return super(Window, self).resizeEvent(event)

    def someFunction(self):
        print("someFunction")        


if __name__ == '__main__':

    app = QApplication(sys.argv)
    window = Window()
    window.setGeometry(300, 100, 600, 600)
    window.show()
    sys.exit(app.exec_())

Как перенести функцию в мой код:

from PyQt5 import QtCore, QtGui, QtWidgets
import sys

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(650, 450)
        self.pushButton = QtWidgets.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(120, 160, 391, 111))
        self.pushButton.setObjectName("pushButton")

        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", "PushButton"))

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

# Тут код программы


sys.exit(app.exec_())

Обьяснил не очень, но надеюсь понятно.

self.resized.connect(self.someFunction)
Вот это вот суёте в setupUi, накидываете на него свою функцию. Всё.

Сделал так:

from PyQt5 import QtCore, QtGui, QtWidgets
import sys

class Ui_Form(object):
    def setupUi(self, Form):
        resized = QtCore.pyqtSignal() 
        self.resized.connect(self.someFunction)
        Form.setObjectName("Form")
        Form.resize(650, 450)
        self.pushButton = QtWidgets.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(120, 160, 391, 111))
        self.pushButton.setObjectName("pushButton")

        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", "PushButton"))

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

# Тут код программы

sys.exit(app.exec_())

Получаю ошибку:

File "C:\Users\User\Desktop\main.py", line 7, in setupUi
    self.resized.connect(self.someFunction)
AttributeError: 'Ui_Form' object has no attribute 'resized'

MrZed, Ui_Form должен наследоваться от MainWindow,

[MrZed]

Вот так?!

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        
        resized = QtCore.pyqtSignal() 
        self.resized.connect(self.someFunction)
        
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(693, 377)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(250, 140, 231, 71))
        self.pushButton.setObjectName("pushButton")
        MainWindow.setCentralWidget(self.centralwidget)

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

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


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())
