Hide OSX menu bar from Qt Application?

fhdns

I want to hide OSX Menu bar and OSX Dock panel. I tried to use this code:

int main(int argc, char *argv[]) {
  QApplication app(argc, argv);
  QDialog* dlg = new QDialog();
  QPushButton* btn = new QPushButton(this);
	connect(btn, &QPushButton::clicked, [this](){
  	[NSApp setPresentationOptions: [NSApp presentationOptions] | NSApplicationPresentationHideMenuBar | NSApplicationPresentationHideDock];
	})
	dlg->show();
  return app.exec();
}

This code hides Dock panel, but doesn't hide Menu bar. by experimentation it was found that the menu does not disappear because Application launched as agent with Info.plist option:

		<key>LSUIElement</key>
		<string>1</string>

If I delete LSUIElement, OSX Dock and Menu bar will be hided, but I don't want that Application has been shown in Dock.

I don't want to use full screen mode dlg->setFullscreen() bexause it creates new OSX screen.

How to doesn't show Application in Dock and hide OSX Menu Bar and Dock panel when Application is active?

Hi,

Out of curiosity, can you describe what your application does that it needs all of these elements hidden ?
