Go-to reference in GTK versus Qt debates, valued for a candid account from experienced developers who tried both toolkits.

Dirk Hohndel explains why the Subsurface dive log project migrated from Gtk to Qt, the obstacles encountered, and advice for other applications frustrated with Gtk. It is a linux.conf.au 2014 talk.

“One of the best discussions on the subject, made by old hackers, but new guys to GUI programming, who tried both” (HN, 2014)

> don't make the mistake of thinking their libraries are meant for others to use I agree. This presentation convinced me: [this video] GTK+ is really just a toolkit for GNOME projects. All other users are secondary.

I think this gets to the core of the problem. The API is out there and open, yet no one (or at least not many people) have decided to try and make a nice GUI client for Linux. Perhaps it's not a problem with Google but more a problem with publishing desktop/GUI software for Linux still being a complete pain in 2015. There's a fantastic talk from Dirk Hohndel last year about how much pain he's gone through creating and publishing a dive logging GUI application for Linux: [this video] If someone like Dirk, who has access to no less than Linus Torvalds himself, has so much trouble creating a modern GUI app on Linux today then how much luck will anyone else have?

on HN thread GTK has a new website
Qt has a company behind so is more professional, better documentation, better cross platform support, less bugs. This video [this video] is about the reasons Subsurface (a diving app started by Linus Torvalds) changed from GTK to Qt. Things might have improved from GTK I can't tell and also for simpler GUIs GTK might be enough.

on HN thread Trinity Desktop Environment R14.0.9 Release Notes
Look at GNOME, notice the giant paddings, title bards see look at the checkboxes,scrollbars etc. Also is not a secret that GNOME developers considered at least touch screens if not tablet when designing the GUI. IMo an informative video on GTK and Qt , it explains what issues you can have with GTK, is about the subsurface application(created by Linus Torwalds that moved to Qt because GTK is bad and even Linus could not get good answers from Red Hat guys) [this video]

on HN thread How Does One Create A Gtk+ Application?
I just watched this [1] video from Dirk Hohndel describing the migration motives and process from Gtk+ to Qt for subsurface (started by Linus). TLDR: * Qt has a community of people developing applications, has good documentation (precise, good coverage) and people who care * Gtk+ has a bunch of Gnome developers, if you want to develop an application, you're out of luck [1]: [this video]

on HN thread KDE makes Qt
Counter point: Dirk Hohndel explains how the Subsurface team was able to implement a much cleaner and simpler GUI in QT than in GTK: [this video] (I've already posted this link in another comment, but here it is again just for relevance) Maybe people don't make that many complex GUIs in GTK cause it's just too hard?

on HN thread Quantum OS - OS based on Linux which conforms to Material Design guidelines
Subsurface, a program for divers, was another high-profile switch. High profile because Linus started it. If he and a bunch of other pretty smart kernel hackers can't figure out GTK, that says something. [this video] On a related note, GNU Radio has a foot in both Qt and WxWidgets and intends to focus on Qt going forward.

> Really depends on what is your definition of "OOP" here I smell a no-true-scotsman incoming.. >> Both Smalltalk and Erlang make use of OOP the way it was originally intended by its inventor, Alan Kay. > ah, the bad definition of OOP then. Message-based OOP is usually considered to be superior to inheritance by even OOP advocates, and even composition-based OOP by many. I don't see your evidence for "bad definition of OOP". >Hint : most C apis that look like > foo* foo_create(void); > int foo_get_bananas(foo ); > void foo_print(foo , int, int); > void foo_free(foo ); > > are OOP, not procedural. They just lack the syntax sugar. Not every API that uses a struct is OOP. If your foos use inheritance, virtual dispatch etc, then yes it's OOP. But usually it's just something like a struct to store state instead of having globals or multiple parameters even. >> Linus Torvalds is widely known for his open criticism of C++ and OOP. > yet he went on doing C++ for user-space code : [this video] He's a pragmatist first and foremost, and the GUI libraries he uses (Qt) and the programmers that work on GUI code use C++, he said. I doubt he would write his own GUI framework in C++.

> That first link especially is hyperbolic disingenuous bad faith nonsense. … I glanced briefly over the other articles and it seems like they're the same utter drivel… …I've explained at length why, and why their UX choices were justified, before… Yep. There we go. Saying anything about GNOME that isn't adoring praise immediately draws out the victim-playing accusations of bad faith, and refusal to engage with the actual problems. How dare anybody scrutinize the way GNOME developers treat and conduct themselves around other people. Nobody can ask GNOME to listen to them, but everybody else must listen to GNOME. There's genuinely something strange going on with the mindset around the whole project; it's like they've actively weeded out anybody with any functioning empathy, self-awareness, or non-zero neuroplasticity… It's not GNOME that's crazy; it's literally everybody else [1][2][3][4][5][6[][7][8][9][10] that's ever tried to work with GNOME! They must be out to get you. --- 1: Solus/Budgie — See second link above. 2: Linux Mint — [link] [link] > We want to send a strong signal upstream and towards other projects. We cannot and will not support applications which do not support our users and environments. 3: Transmission — [link] (Cited in first link, which you dismissed as "Hyperbolic disingenuous bad faith nonsense".) 4: System76 (as villified by GNOME) — [link] (Mentioned in second link, which again you dismissed as "utterly stupid and wrong" "utter drivel".) 5: SpaceFM
