My point of sale software Kassa uses a second monitor to display a client receipt screen.
I am using two main screens for that. The client screen is full screen.
(linux Mint 17.3 64 bit KDE flavour)
void DoMain()
{
	KassaAppWindow app(&session);
	One<KassaClientScreen> clientscreen;
#ifdef PLATFORM_LINUX
	app.OpenMain();
#endif
	if (KassaSettings::UseClientScreen())
	{
		clientscreen.Create();
#ifdef PLATFORM_LINUX
		clientscreen->OpenMain();
#endif
	}
	Ctrl::EventLoop();
}

The above works both on Linux and Windows, however on Linux the client screen also shows on the task bar. That creates confusion and not useful for a full screen display. Is there a way to not show it on the task bar? Note that on Linux I need to Call OpenMain() on the client screen or it won't show at all. On Windows calling OpenMain will freeze the program.

Is this related to the other taskbar issue?

Yes, same project, but not exactly the same. This is about an application with 2 main windows of which I don't want one of them on the task bar. The other is about popups that make dialog windows appear on the task bar.
Alternatively I've been thinking of making the second monitor window a separate program, but that one shouldn't appear on the taskbar at all. Maybe only as tray icon with a fullscreen display on the second monitor.

What about clientscreen->Open(&app) ?
