FLTK VS GTK+

Another dark horse is FLTK: https://www.fltk.org/. For utilities this might be your best choice, especially because static linking is supported. This is mostly a C++ solution but there are bindings to other solutions.

Fl_Flex (shameless plug!) is now officially in upstream FLTK since 1.4 for a "flexbox style" layout manager.

Go ahead and sell an FLTK product then. I'm sure you go to https://www.fltk.org/ and think those GUI's look awesome you delusional moron

FLTK

A few examples: Dear ImGui, SFML, FLTK. Probably even Tk could be used.

FLTK (Fast Light Toolkit) is a lightweight, cross-platform supported toolkit for building GUIs. FLTK is supported on Windows, macOS, and UNIX systems and was originally built for C++. If you use the FLTK toolkit to create a GUI application, the application looks the same on all supported operating systems.

There are a lot of options and they're not that hard to find... Qt, wxWidgets, FLTK, IUP come immediately to mind.

FLTK. It's a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X.

This is the GTK file chooser, not to be confused with the gnome file browser (nautilus). The repo is there. The issue for this particular bug is there. My merge request is there.

GTK and Gnome are almost 25 years old, and they're nowhere as messy as the Windows

I'm trying to port a small GTK3 project over to GTK4 and I'm stuck for a week or so at wrapping my head around menu bars. In GTK3 I used `GtkMenuBar` which is replaced by `GtkPopoverMenuBar` as far as I understand, but I don't understand how. All examples I've found for GMenuModel implemented that hamburger symbol which I don't like (example given).

git clone gtk repo, git checkout the gtk-3-24 branch.

GNOME does maintain GTK. It is the core of their development platform. Its code is even hosted on GNOME's Gitlab

in '~/.config/gtk-3.0/gtk.css' file. Please note this may break some apps somehow. Also, this is not solution, it's only a workaround. It's better to communicate with GTK developers here: https://gitlab.gnome.org/GNOME/gtk

Yeah, that's the Gtk file dialog. Please file a bug report at https://gitlab.gnome.org/GNOME/gtk.

I'm trying to make a text editor in gtk (yes I know there are already plenty of those, but it is a project to learn, not for actual use), and I got pretty far already I would think. I'm basically following the GTK docs for GTK4 and cross checking them with the examples from the GTK git. However I am stuck on something. The current most state of my program is broken, as I get this error when trying to start the program:
