Привет, я новичок в python (до лекции 2 и половины MIT 6001 Введение в информатику и программирование в Python). Тем не менее я начал играть с Gtk & Glade, PyQt5 и Designer.
follow { ссылка } Я использовал pyuic5 для преобразования моего файла prova.ui, сгенерированного Designer, и импортировал его в код ниже:
import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from prova1 import Ui_MainWindow
class MyWindow(QMainWindow):
def __init__(self):
super().__init__()
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.ButtonQ.clicked.connect(self.QPushButtonQPressed)
self.ButtonA.clicked.connect(self.QPushButtonAPressed)
def QPushButtonQPressed(self):
# This is executed when the button is pressed
print('pppppppp exit from QQQQQQQQQQQQQQQQQQQQQQQQQQQQQ')
sys.exit()
def QPushButtonAPressed(self):
# This is executed when the button is pressed
print('exit from AAAAAAAAAAAAAAAAAAAAAAA')
sys.exit()
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MyWindow()
w.show()
sys.exit(app.exec_())
, но когда я запустил его в терминале, я получил :
File "./main.py", line 80, in <module>
w = MyWindow()
File "./main.py", line 38, in __init__
self.ButtonQ.clicked.connect(self.QPushButtonQPressed)
AttributeError: 'MyWindow' object has no attribute 'ButtonQ'
ошибка !!!!
при использовании loadui c вроде:
import sys
from PyQt5 import QtWidgets, uic
class Ui(QtWidgets.QMainWindow):
def __init__(self):
super(Ui, self).__init__()
uic.loadUi('prova1.ui', self)
self.ButtonQ.clicked.connect(self.QPushButtonQPressed)
self.ButtonA.clicked.connect(self.QPushButtonAPressed)
self.show()
def QPushButtonQPressed(self):
# This is executed when the button is pressed
print('pppppppp exit from QQQQQQQQQQQQQQQQQQQQQQQQQQQQQ')
sys.exit()
def QPushButtonAPressed(self):
# This is executed when the button is pressed
print('exit from AAAAAAAAAAAAAAAAAAAAAAA')
sys.exit()
app = QtWidgets.QApplication(sys.argv)
window = Ui()
app.exec_()
программа работает как положено, то есть показывает окно gui и выйти, если нажата кнопка A или Quit
согласно файлу prova1.ui, преобразованному с помощью pyuic5, prova1.py:
# Form implementation generated from reading ui file 'prova1.ui'

Я уверен, что ошибка как-то связанные с определениями классов, но не может действительно gr asp это? Любая помощь?
