您应该在小部件中设置布局,而不是将其设置为 MainWindow,因为您正在使用 MainWindow 类本身,并且在访问类 MainWindow 的方法和属性时,您可以更具体
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_())
