Google To Replace GTK+ With Its Own Aura In Chrome
sfcrazy writes "Google's Chromium team is working on an alternative of Gtk+ for the browser, called Aura. Elliot Glaysher, a Google developer explains, 'We aim to launch the Aura graphics stack on Linux in M35. Aura is a cross-platform graphics system, and the Aura frontend will replace the current GTK+ frontend.' The Free Software community is debating: is Google trying to do Canonical? Couldn't Google just switch to Qt, which is becoming an industry standard?"
And then again, why should anyone have a say on what toolkit Google decide to use for their own browser? Did "the Free Software Community" have anything to say when it was slang vs ncurses, emacs vs vim, gtk vs qt, gnome vs kde? No, because exploring alternate solutions is good for the whole community in the long run. Please stop this poisonous attitude of finding "enemies of the people" among people who dare write free software.
Double-post, but why is this in the news now? All of the linked design docs are from Dec 2011. This stuff is 2 years old.
It's going live now. The stuff has been experimental for that time, it's just now being pushed into Release builds.
Fun fact is that Aura is already enabled on Windows, this is why scrollbars, buttons, combos and everything else now looks like shit and are missing usability features that every other scrollbar on the system has.
Reading through the documents, it doesn't look like a trivial task to recompile all your GTK-2 apps against it. From the UI Toolkit standpoint, it looks like a combination of NextStep and Swing.
AFAIKT Aura is a more than just a UI Toolkit, it's a complete Window Manager. A replacement for Gnome (wow! I hope that takes off!) Apparently it's been running on the Chromebooks. Here is Linus' take on the topic.
The main reason I would be reticent to use it is because Google doesn't always have a strong commitment to backwards compatibility. So you may end up having to rewrite pieces of your code, just to keep them compiling. If you're ok with that though, go for it.
"First they came for the slanderers and i said nothing."
GTK+ 3 is LGPLv2, not GPLv3; it is not developed by the FSF, and never has been. And the GPLv3 is arguably more friendly for businesses than the GPLv2, with its explicit patent provisions, the lack of the termination provision, and the explicit system libraries exception.
I came here to say this.
I'm quite the fan of Qt, but it's far from an industry standard. HTML5 + wrapper probably has as much, if not more, adoption.
And, once you use iOS or Android to dev GUI, some modern, convenient, and well-crafted patterns begin to emerge. They're not perfect, but they're nice to use. Honestly, if Google wants to use their own toolkit and publish it as open source, why should anyone complain about that? Some very interesting ideas may come out of it and be brought into other projects. Just as Mozilla's XUL was clearly aped for Microsoft's XAML, open source contributes to the field as a whole, not just one particular project. There's no need to lick the pizza with open source.
Only the ever-trolling slashdot community could turn Google releasing and dog-fooding an open source project into a bad thing.
i've worked with webkit a *lot*. for example, i helped denis with the port of webkit to directfb. in doing the python-webkit (direct) bindings http://www.gnu.org/software/py... i covered a *lot* of different ports of webkit. here's the summary:
* when compiling the standard webkit to run on a 400mhz ARM9, the gtk port started up in around... i think it was somewhere around 8 seconds. this was tolerable. it used about 130mb of memory to load a single basic page.
* when compiling the DirectFB port to run on the same system, it started up in about 3 to 4 seconds, and used about 1 or 2mb less memory. this was great!
* when compiling the Qt4 port to run on the same system, it took NINETY SECONDS to start up, consumed DOUBLE the amount of memory, and was basically completely intolerable.
the directfb port basically used an older (revision 1.2) version of the lite toolkit. to say it's light-weight would be an understatement: it's absolutely awesome. qt4 has unfortunately turned into a bit of a monster. gtk by comparison has remained reasonably level-headed, and when it (finally!) has the equivalence of COM's co-classes added to the gobject introspection layer gtk will become highly significant, strategically.
the only thing that the directfb-lite port lacked (at the time i was involved) was a window manager. this basically meant that you could only have one browser window open, and you had a callback for dealing with console alerts, which you had to then deal with yourself. i _thought_ about doing the same trick that mozilla does (which is most clearly demonstrated in b2g) - namely to implement the windowing system *in* webkit itself, in a high-level language: that would be cool. not many people are aware that firefox's menus including the toolbars and tabs are actually implemented *in javascript* (!), and the main browser "window" is merely a (secure) frame. b2g is an extension of that.
so anyway, the point is: there are lots of ways this can be achieved. you can implement the window manager externally and treat the browser as an isolated "component". you can go the other route and implement the window manager *using* the browser engine. but the main point is that either way, gtk and qt4 are to be honest complete overkill. it's only when you have things like co-classes built-in to the underlying infrastructure (like COM has) that you get any _real_ flexible benefit from the widget set, and as neither gtk nor qt4 have those, there's honestly really no point having them around.
Is looking darker and darker every year
Actually, Aura has been part of the Chromium project for quite some time, so it isn't any darker today, than it was yesterday, or even last year or two. Most likely, this has more to do with ChromiumOS than Chromium/Chrome.

QT with LGPL could be used freely by google... maybe the problem is control... they could not control GTK and may have fear that QT could neither be controlled by then... Or is just another NIH attack!
