Question

いくつかの機能を持つウィンドウを作成するPyQtスクリプト（端末にpyuic5で作成）があります。この作品とスクリプトは以下の通りです：

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_()) 

これ以降問題が発生します。私はいくつかの機能を作りたい。私はメニューの終了機能から始めました。
終了スクリプトをスクリプトにリンクさせることができません。標準ファイルにはすべてのサブオブジェクトが関連しているオブジェクトmainがあるため、このファイルが作成されると思います。 私はどのように私はこの2番目のスクリプトはmainからオブジェクトを使用することができます取得

（下記スクリプト）私はpyuic5から標準のスクリプトで私のスクリプト（今すぐ上位1）を関連付けることができる方法を見つけ出すことはできませんか？

Answer 1

Qt Designerに追加されたすべてのウィジェットは、単純な名前空間であるself.uiに割り当てられたオブジェクトの属性になります。だから、actionExitにアクセスし、このように、スロットに接続することができます：

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) 

をしかしExit方法は多少の誤差があることに注意して、その代わりに次のようになります。

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() 

あなたがしたい場合はこれで、すべてのWIDを

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) 

：self.uiすべての時間を入力する必要がなくなり、あなたはマルチ継承のアプローチを使用して、物事を少し簡略化することができますQt Designerで追加されるのは、MainWオブジェクトの直接の属性です。
