Hello We are developing GUI programs using PyQt5.
I want to implement the ability to subordinate external programs to follow.
When I searched, C# said that I can call the setParent function, win32gui.There is an error when calling SetParent.
The error content is pywintypes.error: (87, 'SetParent', 'parameters incorrect.') .
Therefore, we used ctypes.windll.user32.SetParent() using ctypes, but the error did not occur, but it did not work properly.
I searched yesterday evening and until dawn, but I don't know how to solve it.
I would appreciate it if you could help me if you know how to attach a different window to the window created by PyQt or what I'm overlooking
The code I wrote about SetParent is as follows.
if __name__ == '__main__':
# Class created using pywin32 library
wh = WindowHelper()
app = QtWidgets.QApplication(sys.argv)
Dialog = QtWidgets.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.setWindowFlag(QtCore.Qt.WindowMinimizeButtonHint)
Dialog.show()
# # SetParent
main = Dialog.winId()
hWnd = wh.getWindow (None, "Calculator")
# Calculator does not move along the main window
ctypes.windll.user32.SetParent(hWnd, int(main))
# Error
win32gui.SetParent(int(main), hWnd)
Please refer to the code below.
import sys
from PyQt5.QtWidgets import QApplication, QWidget
from ctypes import *
class App(QWidget):
def __init__(self):
super().__init__()
self.left=50
self.top=50
self.width=1200
self.height=800
self.initUI()
def initUI(self):
self.setGeometry(self.left,self.top,self.width,self.height)
self.show()
if __name__=='__main__':
FindWindow = windll.user32.FindWindowW
SetParent = windll.user32.SetParent
SetWindowPos = windll.user32.SetWindowPos
notepad_handle = FindWindow (0, "No Title - Windows Notebook")
app = QApplication(sys.argv)
ex = App()
SetParent(notepad_handle, int(ex.winId()))
SetWindowPos(notepad_handle, 0, 100, 100, 400, 600, 0)
sys.exit(app.exec_())
