This package has Build-Depends on GTK 2 (libgtk2.0-dev), or produces
binary packages with a Depends on GTK 2.

GTK 2 was superseded by GTK 3 in 2011 (see
<https://bugs.debian.org/947713>). It no longer receives any significant
upstream maintenance, and in particular does not get feature development
for new features like UI scaling on high-pixel-density displays (HiDPI)
and native Wayland support. GTK 3 is in maintenance mode and GTK 4 is
approaching release, so it seems like a good time to be thinking about
minimizing the amount of GTK 2 in the archive.

GTK 2 is used by some important productivity applications like GIMP, and
has also historically been a popular UI toolkit for proprietary software
that we can't change, so perhaps removing GTK 2 from Debian will never be
feasible. However, it has reached the point where a dependency on it is
a bug - not a release-critical bug, and not a bug that can necessarily
be fixed quickly, but a piece of technical debt that maintainers should
be aware of.

A porting guide is provided in the GTK 3 documentation:
https://developer.gnome.org/gtk3/stable/migrating.html

Some libraries (for example libgtkspell0) expose GTK as part of their
API/ABI, in which case removing the deprecated dependency requires
breaking API/ABI. For these libraries, in many cases there will already
be a corresponding GTK 3 version (for example libgtkspell3-3-0), in which
case the GTK 2-based library should probably be deprecated or removed
itself. If there is no GTK 3 equivalent, of a GTK 2-based library,
maintainers should talk to the dependent library's upstream developers
about whether the dependent library should break API/ABI and switch
to GTK 3, or whether the dependent library should itself be deprecated
or removed.

A few packages extend GTK 2 by providing plugins (theme engines, input
methods, etc.) or themes, for example ibus and mate-themes. If these
packages deliberately support GTK 2 even though it is deprecated, and
they also support GTK 3, then it is appropriate to mark this mass-filed
bug as wontfix for now. I have tried to exclude these packages from
the mass-bug-filing, but I probably missed some of them.

Please find attached patches that port this package to GSettings,
GTK 3 and GooCanvas.  (Only the first two patches in the series are
relevant; the rest are unrelated improvements I consider worth doing,
but YMMV).

While gtk+2.0 removal from Debian is somewhere in the future, this
brings us one step closer to removing libgnomecanvas (only two
packages are left depending on it, not counting amide).

I tested it quite a lot with files downloaded from here:
https://www.rubomedical.com/dicom_files/.  However, as this is a
complex and feature-rich program, it's quite possible that I've missed
something.  (It also goes without saying that I'm not a user of this
package and my knowledge in this area is approximately zero.)

Some time ago Andreas Tille added me as member of Debian Med because
of adun.app, however I wouldn't want to abuse my push access.  I would
suggest that someone from the regular uploaders of this package
reviews the patches first, possibly contacting upstream as well.
Please test extensively, these are major and invasive changes.

P.S.  Someone on the upstream bug tracker suggested that this should
be an intermediate step towards GTK 4.  I could agree but porting to
GTK 4 has to wait for the release of GooCanvas 4.0.  The latest
release (3.0, not yet packaged for Debian) is still based on GTK 3.

We believe that the bug you reported is fixed in the latest version of
amide, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 967252@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
