Yes, but a long time ago in the first year of the project. In this Dec. 2011 post: https://github.com/vmagnin/gtk-fortran/issues/27 My thoughts were: >But in that case, there is no "c:identifier" attribute in the tag (how to identify a pointer ?) > >Advantages: > - parsing XML is easier than using regular expressions which must take > into account many exceptions and peculiarities. > - The binding would be more complete (to what extent ?). >Drawbacks: > - GIR format is not well documented. > - Cairo is not (yet ?) supported.

Or would it be more adequate to > improve cfwrapper.py ? Note that it was how I see things at that time. I don't know if my feeling was right (I was a total beginner with GTK), and I don't know how things have changed since that time. It is still a possibility that could be interesting in the long term. It would surely be cleaner than parsing with regular expressions.

Gtkmm is one of the oldest language bindings for GTK. 2011 is after the creation of g-i, and after Python and Perl got ported to it from their own ad hoc header parser plus ancillary metadata.

Well 172 open issues https://gitlab.gnome.org/GNOME/gobject-introspection/issues but indeed there is some activity. I think 3 years ago when I started the gobject-introspection bindings it was nearly death. >gtkmm is an old binding, and it's very much set it its ways.

It most definitely is not. The project is actively maintained, and it recently got even a full description of the XML schema: https://gitlab.gnome.org/GNOME/gobject-introspection/blob/master/docs/gir-1.2.rnc The documentation has also been updated: https://gi.readthedocs.io/en/latest/ Starting with the API docs was really hard, took me some > hundreds hours before useful code generation started. libgirepository is mostly meant to be used by dynamic languages, not for code generation. It's also heavily modelled on the requirements of existing language bindings like pygobject for Python; Glib::Object::Introspection, for Perl; and GJS for JavaScript. API can be added, but the on disk file format is stable, so it cannot really be changed outside of the current boundaries of its ABI. Code generation typically starts from the GIR file format—for instance, the Rust bindings use it to generate static bindings: https://github.com/gtk-rs/gir Note that Gtkmm does > not use GObject introspection still. > gtkmm is an old binding, and it's very much set it its ways. Newly written bindings should not go down the same route.

But a warning: GObject introspection is not that much fun, as it is in zombie state. Starting with the API docs was really hard, took me some hundreds hours before useful code generation started. Well, I started from scratch, but with some help of Mr Mansour. Maybe a start with a copy, maybe from python would have been easier. Note that Gtkmm does not use GObject introspection still. ___ gtk-list mailing list gtk-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-list

Re: gtk-fortran 19.04 released
Dear Stefan, I am one of the main authors and administrators, working on the python script used to parse the GTK .h header files and generate the Fortran interfaces. I wrote some messages in the GTK+ forum in 2011 about gtk-fortran, but it seems I had not registered at that time: http://gtk.10911.n7.nabble.com/new-gtk-fortran-binding-td16952.html Personally I am a simple user of GTK3, using it to create simple GUIs for scientific computing, like in that example: https://github.com/vmagnin/gtk-fortran/blob/gtk3/screenshots/julia_pixbuf-kubuntu_16_04.png I just need to visualize results progressively during long computations (which can last 10 minutes, or several hours, sometime several days). I have long worked with Compaq Visual Fortran (now Intel Fortran) 15 to 20 years ago, which was offering the QuickWin library to create Fortran programs with graphical windows, but of course only under... Windows. Having migrated toward Linux since mid 2000's, I have looked for a free equivalent cross-platform tool for a long time, and finally launched the gtk-fortran project at the beginning of 2011. There have been high and lows in the development of gtk-fortran but I found some time and new energy these last six months to make a lot of cleaning in the project and make a new release. Concerning the "new discourse forum", I am not sure of what you mean. I do not see such a forum on this page: http://gtk.10911.n7.nabble.com/ If the "Gtk+ - General" forum is not the good place to post my message, I apologize. It just seemed the less bad place for a Fortran thing... -- Sent from: http://gtk.10911.n7.nabble.com/Gtk-General-f47634.html ___ gtk-list mailing list gtk-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-list

I know how much work such bindings take, I created the Nim bindings twice, oldgtk3 lowlevel bindings, and high level gintro ones :-) Are you the main author, or do you have at least some understanding of GTK3?

gtk-fortran 19.04 released
Hello, Launched in 2011, the gtk-fortran library offers interfaces to around 1 GTK functions (GTK, GDK, GdkPixbuf, Cairo, Pango, ATK, GLib, GObject, GIO) using the ISO_C_BINDING module. Although mainly developed under Linux, you can easily use it under Windows via MSYS2. It runs also under UNIX systems like BSD and macOS. Note that gtk-fortran offers also an interface to PLplot. It is distributed under GNU GPLv3 license. The 19.04 release is based on GTK 3.24.8, GLib 2.60.0 and GTK 2.24.32. Main new features are: - tools to identify deprecated GTK functions, - parallel building (make -j) for the gtk3 branch, - an improved and updated documentation, - bug fixes in the examples - ... Concerning the future, the project is slowly preparing to the arrival of GTK 4. A migration from CMake to Meson (now used by GTK) is also considered. New contributors are of course welcome ! (We are not Legion).
