Bug#994580: zenity: Zenity --question return values inconsistent

[Anon1336]

Package: zenity
Version: 3.30.0-2
Severity: normal
Tags: a11y upstream

Dear Maintainer,

When calling Zenity with --question the return values SHOULD be 0 or 1 (or
ever-increasing numbers if buttons are added). However, the return value is
either nothing or 0. Example:

someVar=$(zenity --question [blah] [blah]) && echo $someVar
OR
zenity --question [blah blah] && echo $?

Please note: I have tried the latest Zenity version from sid and the problem
persists.

This can affect shell scripts for which Zenity was designed. There
is an obvious workaround, [[ -z "$someVar" ]], the trouble will come when/if
this is fixed. The better workaround, when considering more than two buttons
as well, is a case statement so that any return except what which is fixed or
unfixed, is handled instead. It will obviously still cause a little conflict,
but it needs to be fixed, the sooner, the better. Obviously this an upstream
problem, but it's an easy fix.

Regards,
J
