I think your question is quite reasonable. Imagine a Linux host
running X Windows and a terminal like xterm or kconsole.
Then run a program like "top" or "less" in this terminal.
When a user changes the size of the console window, top, less
and other console applications get notified of this change by SIGWINCH.
Now run a similar program using QEMU's user mode emulation.
Why should it not be possible to get SIGWINCH in QEMU and
pass it on to the program in user mode emulation, so it can
behave like a native Linux application and change its appearance?
I don't think that implementing this is very difficult, so it will be
done.
