前言： 使用焦点事件处理程序，而不是鼠标移动处理程序来执行此 。

您可以使用 win32gui 强制嵌入式窗口处于活动状态，即使它已被qt吸收。

win32gui.BringWindowToTop(hWnd)
win32gui.SetFocus(hWnd)

在这个例子中，我包含了它，每次它检测到GUI中的鼠标移动时都会运行。理想情况下，您希望每次单击QWidget内部时都要执行它，但我对PyQT5相对来说并不熟悉，而且还没有学会如何正确地执行。

示例中的固定代码：

class MainWindow(QMainWindow):
    Launches the terminal
    def __init__(self, command: str, substring: str):
        super(MainWindow, self).__init__()
        win = latchToWindow(command, substring)
        self.hwnd = win._hWnd
        widget = widgetMouseTracking(self.hwnd)
        widget.setMouseTracking(True)
        layout = QGridLayout(widget)
        self.setCentralWidget(widget)
        self.window = QtGui.QWindow.fromWinId(self.hwnd)
        self.windowcontainer = self.createWindowContainer(self.window, widget)
        layout.addWidget(self.windowcontainer, 0, 0)
class widgetMouseTracking(QWidget):
    def __init__(self, windowsID):
        super().__init__()
        self.id = windowsID
    def mouseMoveEvent(self, a0: QtGui.QMouseEvent):
        win32gui.BringWindowToTop(self.id)
        win32gui.SetFocus(self.id)
def latchToWindow(winLaunchCommand: str, gettitle: str):
    Used when there are additional dialogs and you need to grab a specific one
    :param winLaunchCommand:
    :param title:
    :return:
    makeNewWindow(winLaunchCommand)
    while True:
        windows = pygetwindow.getAllWindows()
        for win in windows:
            tempTitle = win.title
            if gettitle in tempTitle:
                return win
        time.sleep(0.1)
def makeNewWindow(winLaunchCommand: str):
    Makes a new window with that command, and returns that window
    :param winLaunchCommand:
    :return:
    windows = pygetwindow.getAllWindows()
    os.popen(winLaunchCommand)
    while True:
        newWindow = pygetwindow.getAllWindows()
        if len(newWindow) != len(windows):
            for win in newWindow:
                if win.title != "":
                    if win not in windows:
                        time.sleep(0.05)
                        return win
if __name__ == '__main__':
    app = QApplication(sys.argv)
    app.setStyle("fusion")
    # This doesn't work with keyboard and mouse
    form = MainWindow("start cmd.exe", "cmd.exe")
