Close a QMainWindow from full screen

blackout69

Hello
I have my own QAxWidget application that I need to embed on a QMainWindow

WId wid = (WId)FindWindow(L"ScreenClass", nullptr);
window = QWindow::fromWinId(wid);

For internal application requirements, I am forced and run QMainWindow with the following flag:

this->setWindowFlags(Qt::WindowDoesNotAcceptFocus);

The application works well, the only problem is that I can't find an event to close the application with Escape key.
I tried that, but it doesn't work because of the WindowDoesNotAcceptFocus flag.

void FullScreen::keyPressEvent(QKeyEvent *event)
{
  if (event->key() == Qt::Key_Escape)
	{
		close();
	}
}

While with a double click it exits.

void FullScreen::mouseDoubleClickEvent(QMouseEvent *event)
{
	 close();
}

What I ask, some ideas to close the application with a key on the keyboard.
Thank you in advance
