在 PyQt 应用程序中运行 Windows 可执行文件(calc.exe 等) [英] Running a Windows executable (calc.exe, etc) inside a PyQt Application

问题描述

我正在尝试在使用 PyQt5 用 Python 编写的应用程序中运行 Windows 可执行文件.我对使用 PyQt5 还很陌生，但正在尝试.

I'm trying to run a Windows executable inside my application written in Python using PyQt5. I'm fairly new to using PyQt5 but trying.

我面临的问题实际上是让有问题的 EXE 在我的应用程序框架、窗口或 QWidget 中运行.

The problem I'm facing is actually getting the EXE in question to run within my applications Frame, Window or QWidget.

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

At the moment I don't need to send or get responses/results to and from the Windows executable, I only need the ability to show it within my application.

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:

What I get from the following Code is this:

推荐答案

抱歉，我不知道我是否理解正确，但我建议您试试这个:

Sorry, I don't know if I understood you correctly, but I suggest trying this:

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, 0, 0, 2, 1)
        
        self.v_layout = QVBoxLayout(self.widget)
        self.initUI()
        self.grid_layout.addWidget(self.label, 0, 1, 1, 1) 
 
    def initUI(self):
        t = threading.Thread(target=self.runExe)
        t.start()
        #                                                 Calculator
        hwnd1 = win32gui.FindWindowEx(0, 0, "CalcFrame", "Калькулятор")
        start = time.time()
        while hwnd1 == 0:
            time.sleep(0.01)
            #                                                 Calculator 
            hwnd1 = win32gui.FindWindowEx(0, 0, "CalcFrame", "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_())
