I am developping a gui application on Python with PySide2. I'm using fromWinId and createWindowContainer functions to embed an external window app in my app. It's perfectly working on Windows, I can access my embedded app (Paint app for example). But on Linux, it's not working the same. I manage to get the window id of the external app and to embed it my app, but when it's embedded, I only have a frozen image of the external app. This is my code :
import Xlib.display
from PySide2.QtGui import QWindow
from PySide2.QtWidgets import QWidget, QApplication, QPushButton, QMainWindow, QVBoxLayout
def _get_window_id_win32(title):
import win32gui
return win32gui.FindWindow(None, title)
def get_window_id_linux(name):
display = Xlib.display.Display()
root = display.screen().root
window_ids = root.get_full_property(display.intern_atom('_NET_CLIENT_LIST'), Xlib.X.AnyPropertyType).value
for window_id in window_ids:
window = display.create_resource_object('window', window_id)
window_name = window.get_wm_name()
if window_name and name in window_name:
return window_id
def run_app(window_id):
app = QApplication([])
main = QMainWindow()
widget_central = QWidget()
layout = QVBoxLayout()
button = QPushButton()
button.setText('CLICK')
layout.addWidget(button)
window = QWindow.fromWinId(window_id)
widget = QWidget.createWindowContainer(window)
layout.addWidget(widget)
widget_central.setLayout(layout)
main.setCentralWidget(widget_central)
main.show()
app.exec_()
if __name__ == '__main__':
window_id = get_window_id_linux('Window Title') # REPLACE 'Window Title' by the title of the window you want to embed
# window_id = _get_window_id_win32('Window Title') IF YOU WANT TO TEST ON WINDOWS
if window_id:
run_app(window_id)
