OK, so assuming an OS similar to X, can a single app support two
forms on different displays, and/or move forms between displays?
That's the job of the desktop/window manager, on every OS. When a form
shall be updated on screen, the manager determines the monitor from
the form's screen coordinates, then asks the form to paint itself.
Moving forms means nothing but changing their screen coordinates, then
request an screen update.
My understanding is that moving forms *between* *displays* requires
rather more than that, in fact I'm not sure it's doable on X (if it were
then we wouldn't need Xinerama, Xdmx etc.).
Try to move a form with the mouse to an different monitor. This works on
Linux without additional libraries. Linux also can show the same form on
all desktops, without additional code or libraries.
If you mean "desktops" for "displays", or different X sessions, that's a
bit different. But even then it's only a process property, on which
desktop or X session a form is shown.
