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GTK 2 was superseded by GTK 3 in 2011 (see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.

Hi smcv,

[...]
upstream). My career has moved into a different direction and it does
not look like anyone else picked up the project upstream in the meantime.
So: it is unlikely that LTRsift will be ported to GTK3 in the near
future or even in the medium term. I am truly sorry but that's how it is.

I am prepared to accept removal of LTRsift as a consequence of
potential removal of GTK2 from Debian, should it ever happen.

Best regards
Sascha

As announced [1], we are trying to remove gtk2 from forky. Therefore,
I am raising the severity of this issue.

Hello,

Bug #967603 in ltrsift reported by you has been fixed in the
Git repository and is awaiting an upload. You can see the commit
message below and you can check the diff of the fix at:

https://salsa.debian.org/med-team/ltrsift/-/commit/4bb3a3ec6090888079ad685057c1823fe58f1aa6
------------------------------------------------------------------------
Port LTRsift from GTK+ 2 to GTK+ 3

The GTK+ 2 development files are no longer available in Debian.
Update the build system to use GTK+ 3, adapt the custom widgets to
GTK+ 3 (GtkObject removal, GtkComboBoxText, dialog content area,
GtkWidget allocations and the draw signal) and use the renamed
key symbols.

Closes: #967603
