I mean... a top-level window. A form if you prefer.

Not necessarily.

> Can it be a visible control?  A container?

The systray needs a X11 parent window. Alas only a top-level window is guaranteed to have one whatever the underlying GUI toolkit. So it's simpler to always use a op-level window, and the new X11Systray.Move() method to position your systray inside your top-level window.

> Is the systray affected by the form's automatic arrangement or must it be handled manually?

The systray must be moved and resize manually with X11Systray.Move().
The systray icons must be moved and resized manually as before during the X11Systray_Arrange() method.

> Do you have any sample/test code?

I will see if I can make one for you.

But I have to tell you that X11 systray is deprecated, will may be removed sooner than later, and that you should really make a DBus system tray instead,
following these specifications :
