I like GTK, but it's place is in gnome (which I also like) and no where else, on any other system it looks horrible and out of place, particularly when it comes to things like the file dialog.

Also the devs no longer consider it a cross platform library, everyone using it as one is stuck on GTK2.

GTK is a bazaar style project, if it has issues on some platform then that's because no developers have stepped up to fix issues on that platform.

There's support for Windows native file dialogs since 3.20.

(Not OP) Most gtk applications are very difficult for me to use, for a combination of reasons. I have joint problems that mean I rely on mouse and touch for working with text more than most people. The biggest obstacles are:

1. Gtk constantly clobbers the middle-click clipboard on Linux. In non-gtk programs that's one of my most efficient ways of entering and editing text.

2. Gtk completion dropdowns steal clicks, so typing into a field with completions (that I don't want) with an onscreen keyboard takes at least twice as many button presses as it should.

I have no such problems with Qt (or anything else).

Not-Gnome was never a priority for the developers, conversely, it doesn't work very well on Not-Gnome. That alone disqualifies it for me. Besides that, the docs are simply bad and glib is such a huge mess that I actively avoid touching anything near it with a ten foot pole.

@dom0 @flukus of course, thanks. Didn't think of that as I am a satisfied GNOME user (for the continued focus on UX refinement, simplicity, stability) and was even forgetting people might consider it for non-GNOME.
