[Mac OS] Resize window for two monitors

[ecspertiza]

Hi all. I have problem with mac os and resize windows for tow monitors.

I try call

QQuickView::showFullscreen();

QQuickView::showFullscreen();

To copy to clipboard, switch view to plain text mode 

but QQuickView resize on primary desktop.

ok, i try call

void Window::show() 
{
 
  QRect screenRect;
  QList<QScreen *> screenList = QGuiApplication::screens();
 
  for (int i = 0 ; i < screenList.count(); ++i) {
      screenRect = screenRect.united(screenList.at(i).geometry());
  }
 
  setGeometry(screenRect);
  QQuickView::show();
}

void Window::show() 
{

  QRect screenRect;
  QList<QScreen *> screenList = QGuiApplication::screens();

  for (int i = 0 ; i < screenList.count(); ++i) {
      screenRect = screenRect.united(screenList.at(i).geometry());
  }

  setGeometry(screenRect);
  QQuickView::show();
}

To copy to clipboard, switch view to plain text mode 

i see half window on primary screen, and all, tow half not visible.

How i can resize window for tow monitors ?
