我是 Qt5 的新手，我有一個簡單的 QGridLayout 布局掩碼。我想用調整窗口大小的小部件創建一個窗口這是代碼import sysfrom PyQt5 import QtCore, QtGui, QtWidgetsfrom PyQt5.QtWidgets import QFileDialog ,QVBoxLayout,QGroupBox,QGridLayoutclass MainWindow(QtWidgets.QMainWindow, QtWidgets.QFileDialog, QtWidgets.QLineEdit): def __init__(self): super().__init__() self.title = "Calcolo Hash" self.top = 100 self.left = 100 self.width = 800 self.height = 330 self.InitWindow() def InitWindow(self): self.setWindowIcon(QtGui.QIcon("icona_aprie.png")) self.setWindowTitle(self.title) self.setGeometry(self.top, self.left, self.width, self.height) self.creamaschera() self.show() def creamaschera(self): print ("creazione maschera") layout = QtWidgets.QGridLayout() self.txtcartella = QtWidgets.QLineEdit() self.lblprova = QtWidgets.QLabel("Please enter new name:") # self.txtcartella.setGeometry(QtCore.QRect(10, 10, 301, 20)) # self.txtcartella.setObjectName("txtcartella") layout.addWidget(self.lblprova,0,0) layout.addWidget(self.txtcartella,0,1) self.setLayout(layout) # self.horizontalGroupBox.setLayout(layout)if __name__ == "__main__": app = QtWidgets.QApplication(sys.argv) w = MainWindow() #w.show() sys.exit(app.exec_())但是當我運行時，面具是空的。我用 Qt5 設計器制作基礎并將其轉換為 python。我想在最佳訓練中重構課程。錯誤在哪里？

您應該在小部件中設置布局，而不是將其設置為 MainWindow，因為您正在使用 MainWindow 類本身，并且在訪問類 MainWindow 的方法和屬性時，您可以更具體
import sys
from PyQt5 import QtCore, QtGui
from PyQt5.QtWidgets import (QLineEdit, QMainWindow, QWidget,
QGridLayout, QLabel, QApplication)
class MainWindow(QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
self.title = "Calcolo Hash"
self.top = 100
self.left = 100
self.width = 800
self.height = 330
self.InitWindow()
def InitWindow(self):
self.setWindowIcon(QtGui.QIcon("icona_aprie.png"))
self.setWindowTitle(self.title)
self.setGeometry(self.top, self.left, self.width, self.height)
self.creamaschera()
def creamaschera(self):
print("creazione maschera")
Layout = QGridLayout()
self.txtcartella = QLineEdit()
self.lblprova = QLabel("Enter Your Name")
self.lblprova.setGeometry(QtCore.QRect(15, 15, 301, 20))
self.txtcartella.setObjectName("txtcartella")
Layout.addWidget(self.lblprova, 0, 0)
Layout.addWidget(self.txtcartella, 0, 1)
# Widget to setLayout in it since you are using MainWindow as an Class
widget = QWidget()
widget.setLayout(Layout)
# SetCentralWidget without this widget won't be placed
self.setCentralWidget(widget)
# self.horizontalGroupBox.setLayout(layout)
if __name__ == "__main__":
app = QApplication(sys.argv)
MainWindow = MainWindow()
MainWindow.show()
sys.exit(app.exec_())
