在PyQt应用程序中运行Windows可执行文件calc.exe等

如何解决在PyQt应用程序中运行Windows可执行文件calc.exe等

我正在尝试使用PyQt5用Python编写的应用程序内部运行Windows可执行文件。我是使用PyQt5的新手，但是尝试一下。

我面临的问题实际上是让有问题的EXE在我的应用程序Frame，Window或QWidget中运行。

目前，我不需要向Windows可执行文件发送或从Windows可执行文件获取响应/结果，我只需要能够在我的应用程序中显示它。

class MyWindow(QWidget):

   def __init__(self):
     super().__init__()

     self.initUI()

   def initUI(self):
     # create a process
     exePath = "C:\\Windows\\system32\\calc.exe"
     # subprocess.Popen(exePath)
     os.system(exePath)
     hwnd = win32gui.FindWindow(0,"Calculator")
     print(hwnd)
     time.sleep(0.05)
     window = QtGui.QWindow.fromWinId(hwnd)

     self.createWindowContainer(window,self)
     self.setGeometry(500,500,450,400)
     self.setWindowTitle('File dialog')
     self.show()

def main():
  app = QApplication(sys.argv)
  w = MyWindow()
  sys.exit(app.exec_())


if __name__ == '__main__':
    main()

我从以下代码中得到的是这样：

解决方法

对不起，我不知道我是否正确理解了您，但我建议您尝试以下方法：

import sys
import subprocess
import threading
import time
import win32gui
from PyQt5.QtCore    import Qt
from PyQt5.QtGui     import QWindow,QPixmap
from PyQt5.QtWidgets import (QWidget,QApplication,QVBoxLayout,QGridLayout,QMainWindow,QLabel) 


class Example(QMainWindow):
    def __init__(self):
        super().__init__()

        self.central_widget = QWidget()
        self.setCentralWidget(self.central_widget)
        
        self.widget = QWidget()
        self.widget.setFixedSize(230,280)
        self.widget.setStyleSheet("background-color: yellow;")
        self.label = QLabel(self)
        self.label.setPixmap(
            QPixmap('images/splash_.jpg').scaled(self.size().width()/2,self.size().height())
        )
        
        self.grid_layout = QGridLayout(self.central_widget)
        self.grid_layout.addWidget(self.widget,2,1)
        
        self.v_layout = QVBoxLayout(self.widget)
        self.initUI()
        self.grid_layout.addWidget(self.label,1,1) 
 
    def initUI(self):
        t = threading.Thread(target=self.runExe)
        t.start()
        #                                                 Calculator
        hwnd1 = win32gui.FindWindowEx(0,"CalcFrame","Калькулятор")
        start = time.time()
        while hwnd1 == 0:
            time.sleep(0.01)
            #                                                 Calculator 
            hwnd1 = win32gui.FindWindowEx(0,"Калькулятор")
            end = time.time()
            if end - start > 5:
                return
        window = QWindow.fromWinId(hwnd1)
        widget = self.createWindowContainer(window,self.central_widget)
        self.v_layout.addWidget(widget)
 
    @staticmethod
    def runExe():
        exePath = "C:/Windows/system32/calc.exe"
        subprocess.Popen(exePath)

 
if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = Example()
    ex.resize(550,400)
    ex.show()
    sys.exit(app.exec_())
