Problem accessing figures in docs.huihoo.com/gtkmm/programming-with-gtkmm-3

It’s great that this is being kept somewhere that it can still be found. Unfortunately, the figures all give 404 errors when you try to open them.

The maintainers could solve this issue with a trivial edit.

The links all have an ending of “.en” . However, the images in the repository do not.

For example, the link

https://docs.huihoo.com/gtkmm/programming-with-gtkmm-3/3.8.0/en/figures/treeview_list.png.en

gives an error, because the actual image is here:
https://docs.huihoo.com/gtkmm/programming-with-gtkmm-3/3.8.0/en/figures/treeview_list.png

Wouldn’t it be dandy if the owner would take a few minutes and remove the “.en” suffixes from the links?

What is docs.huihoo.com? Looks like a Chinese site. I won’t even try to change anything there.

If you had used gtkmm4, I would have recommended gnome.pages.gitlab.gnome.org/gtkmm-documentation

There is no similar site for gtkmm3. After all, it’s old. Have you thought of switching to gtkmm4?

What I can recommend for Programming with gtkmm 3 is:
Download a fairly new tarball, for instance
https://download.gnome.org/sources/gtkmm-documentation/3.24/gtkmm-documentation-3.24.5.tar.xz
Expand it, and open docs/turorial/html/index.html. It does not work with old tarballs, like 3.8.0 from June 2013.
