Does an X client process always have one or more GUI window(s)?
Conversely, if a process has one or more GUI window(s), is it an X client process?
Does an X client never have a controlling terminal? Does the concept of "controlling terminal" only apply to processes which have no GUI window?
Thanks.

An X client does not need to open a window; there are many utilities, e.g.,xdpyinfoorxwininfo, which talk to the X server but don't open windows. A process which use a GUI window to interact with the user may or may not be an X client, depending on what mechanism is uses to use that window. For example, a shell uses a terminal emulator window to interact with the user, but it's not an X client. An X client may or may not have a controlling terminal; for example, runxclockfrom the command line in a terminal emulator, and press Ctrl-C to check whetherxclockterminates or not.

Not to mention that on some moderny Linux distributions there are many graphical programs which don't use X at all, because for example they use Wayland.
