我有一个pyQt脚本（在终端中用pyuic5创建），它创建了一个带有一些功能的窗口。这个工作和脚本如下：
from PyQt5 import QtCore, QtGui, QtWidgets
from Main import Ui_Main
from resources.icons import *
import sys
class MainW(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MainW, self).__init__(parent) #pyQt5
self.ui = Ui_Main()
self.ui.setupUi(self)
self.ui.setupUi
self.ui.retranslateUi(self)
# self.ui.setWindowIcon(QtWidgets.QIcon('MeasLogoSm.png'))
# self.ui.setWindowTitle("Meas Sound Measurement Tool")
self.ui.progressBar.setProperty("value", 1)
# measExit = self.ui.menuJBae_Meas.addAction(self.ui.actionExit)
# measExit.triggered.connect(self.Exit)
def Exit(self):
choice = QtGui.QMessageBox.question(self, 'Exit Meas',
"Are You sure to Leave Meas?", QtGui.QMessageBox.Yes | QtGui.QMessageBox.No)
if choice == QtGui.QMessageBox.Yes:
sys.exit()
else:
pass
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
mainapp = MainW()
mainapp.show()
sys.exit(app.exec_())
此后问题出现了。我想创建一些功能。我从菜单中的退出功能开始
我无法将退出脚本链接到脚本。我认为这是因为标准文件有一个对象main，其中所有子对象都与之相关。
我无法弄清楚如何将我的脚本（现在是上面的脚本）与pyuic5的标准脚本（下面的脚本）联系起来

第二个脚本如何使用main中的对象？
答案 0 :(得分：0)
Qt Designer中添加的所有小部件都成为分配给self.ui的对象的属性，这只是一个简单的命名空间。因此，您可以访问actionExit并将其连接到插槽，如下所示：
class MainW(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MainW, self).__init__(parent)
self.ui = Ui_Main()
self.ui.setupUi(self)
# self.ui.setWindowIcon(QtWidgets.QIcon('MeasLogoSm.png'))
# self.ui.setWindowTitle("Meas Sound Measurement Tool")
self.ui.progressBar.setProperty("value", 1)
self.ui.actionExit.triggered.connect(self.Exit)
但请注意Exit方法有一些错误，应该是这样的：
def Exit(self):
choice = QtWidgets.QMessageBox.question(self, 'Exit Meas',
"Are You sure to Leave Meas?",
QtWidgets.QMessageBox.Yes | QtWidgets.QMessageBox.No)
if choice == QtWidgets.QMessageBox.Yes:
self.close()
如果您不想一直输入self.ui，可以使用多继承方法简化一些事情：
class MainW(QtWidgets.QMainWindow, Ui_Main):
def __init__(self, parent=None):
super(MainW, self).__init__(parent)
self.setupUi(self)
# self.setWindowIcon(QtWidgets.QIcon('MeasLogoSm.png'))
# self.setWindowTitle("Meas Sound Measurement Tool")
self.progressBar.setProperty("value", 1)
self.actionExit.triggered.connect(self.Exit)
现在，Qt Designer中添加的所有小部件都是MainW对象的直接属性。
