Qt's default webkit user agent
by Benjamin Meyer 01 Dec '08

01 Dec '08

As it is today Qt's default user agent (in qwebpage.cpp) is hard coded to: "Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en) AppleWebKit/523.15 (KHTML, like Gecko) Safari/419.3 Qt" Seeing as this library will be used inside of many other applications it makes sense to include by default at least the application name/version when they are set. QCoreApplication gives us several strings which can be used. applicationName, applicationVersion, organizationDomain, organizationName But at a bigger question, what should be included (or not included) with the default user agent? Is there docs anywhere that suggest what webkit library users should use as their user agent string? -Benjamin Meyer

proxying thru curl
by Giri Rao 01 Dec '08

01 Dec '08

Hello, I have set up curl to go through a simple http proxy that I have written. I have a .curlrc with the following line in it: --proxy=http://<myhost>:<myport>/ When I invoke curl on command line, it goes thru the set proxy. However, when I launch webkit through GtkLauncher, it does not seem to go through the proxy at all. Is my understanding wrong in that webkit uses curl to fetch content? How do I make webkit go through my proxy? Any help is appreciated. Thanks Giri

webkit documentation

Hi all, I am mainly interested in S60 WebKit, however due to the project seeming to be in complete disarray to those not working for Nokia, I've decided to focus my efforts on the WebKit branch from which S60 WebKit started. I understand this to be Tiger 10.4.7 (it was one of the few pieces of information about S60 WebKit that I could actually find - although it will almost certainly turn out to be incorrect :p): http://trac.webkit.org/browser/releases/Apple/Tiger/Mac%20OS%20X%20Update%2… Where can I find documentation for this code? The question here is, other than trawling through code, where can I find documentation that explain it's implementation? Cheers, Jack

I'm not happy with the code organization here. XMLTokenizer now has tons of ifdefs and two separate implementations. It's fine to have a QXmlStream implementation, but the two implementations should be in separate files, side by side, as we do in the platform layer. Or the XML parser should be abstracted out so we have a single XMLTokenizer built on a single parser abstraction. I think this is also the type of patch that should be reviewed by at least one person other than the folks concentrating on the Qt port. With the huge number of check-ins today, I'm sure there are other interesting things like this that I missed. -- Darin

how do you do callbacks out of webkit into c++, objC or other bindings - e.g. "onclick" ?
by Luke Kenneth Casson Leighton 31 Aug '08

31 Aug '08

pyjamas-desktop is the test-case for the glib bindings - but ignore that, i have a general question for which pyj/d is a specific case: in javascript, you can set an element's "onclick" method. how the heck do i get a callback, into c++, objc or any other binding, from an "onclick"? is there a mechanism for calling back, from javascript, into the "bindings"? so, for example, i could set an element's "onclick" method to call "hello_now_we_are_going_to_pass_all_our_arguments_to_the_binding(...)"? i've already set up an EventListener (using addWindowEventListener) but that's far from ideal, although it does take in eeeverything, which is required in a lot of instances in pyjamas, to handle e.g. mouse-move events, and to handle "event preview", thus allowing opportunities to stop event propagation... .. all that's taken care of. what _isn't_ taken care of is overriding window "onresize", element "onclick", window "onbeforeclose", window "close", element "onblur" and all the other loovely events that are usually the exclusive domain of javascript. .. how do i get em? :) tia, l.

pyjamas-desktop / webkit / pywebkitgtk - running AJAX web apps... as a desktop app!
by Luke Kenneth Casson Leighton 29 Aug '08

29 Aug '08

code references and patches: git@github.com:lkcl/pyjamas-desktop.git https://bugs.webkit.org/show_bug.cgi?id=16401 http://code.google.com/p/pywebkitgtk/issues/detail?id=13 first things first: thank you to everyone on the gtk and webkit mailing lists and irc over the past week for helping answer numerous questions, i just wanted to let you know that, with your help, enough has been done for me to move on to developing pyjamas-desktop properly. (what is pyjamas-desktop?) based on webkit, it's a cross-platform application development API. like pygtk, like python-qt4 and wxWidgets, only much cooler because you can, if you want, load *complete* html pages, *complete* stylesheets, and even execute bits of javascript if you're feeling particularly obtuse. (wow. how?) because it's based on webkit. so you get access to the DOM model, you get full HTML compliance, wickedly-fast javascript execution, media plugins, CSS stylesheets - everything. (whoaaaa - bbb..back up a bit: what's pyjamas?) based on http://code.google.com/webkit, pyjamas is a cross-browser _web_ application development API. it looks and smells like a desktop API, but underneath, pyjamas is an AJAX library and a comprehensive widget set (implemented as AJAX but you *never* go anywhere near javascript, because at the core of pyjamas is a python-to-javascript compiler). in short, you get to write apps that _look_ like they ought to be running on a desktop, and pyjamas takes care of all the nasty browser tricks that you would normally take _months_ to code up - if you bothered at all - for safari, opera, IE7, IE6, firefox, mozilla, midori... .. even konqueror nearly works if you twist its arm hard enough. (what's the fuss, then?) pyjamas-desktop is a project to port pyjamas - the toolkit that was ported to java - the one that looks like it _ought_ to run on the desktop - to the desktop. (i don't get it. so what??) you get to run the SAME application source code (written in python) as EITHER a web application - on 99% of browsers in use today - OR as a desktop application - on as many environments as webkit (well, actually, pywebkitgtk at the moment) will compile on. effectively, pyjamas becomes a "standard" for application development. cross-browser. cross-platform. even cross _widget_ set, if someone wants to create pywebkitqt4 and the associated qt DOM model webkit bindings. and a python-wxWidgets one. (you... huh?? i'm having difficulty getting my head round the significance) free software from ground up home-grown alternative to silverlight. free software from ground up home-grown alternative to adobe AIR. (why??) because, as it's web-based, being based on webkit, any media plugins that webkit support, now and in the future, you can "embed", control, and interact with, through the webkit API. e.g. flash plugins. (what else? got a kitchen sink to throw in with that?) this isn't burger king, you can't have fries - but you _can_ have an event sink, rather than a kitchen sink. and yes, you _can_, through the glib-gobject bindings, access and control webkit's DOM model through perl, *mm, or whatever obtuse language you choose. my obtuse language of choice is python; h2defs.py / pygtk-codegen made short work of turning the glib header files into python bindings, and we're off. (what's the catch?) there is a hell of a lot left to be done - however, it shouldn't take too long. i did a part-port of pyjamas to gtk2 in a few days - enough to tell me that i was wasting my time ... ( http://lkcl.net/pyjamas-desktop/pygtk2.tgz if anyone's interested) .. due to the lack of support for libgtkhtml3 which has a crucial feature i needed. i did a part-port of pyjamas to qt4 in about _two_ days... (http://lkcl.net/pyjamas-desktop/pyqt4.tgz if anyone's interested) ... enough to know that, despite the rich-text support, the layout mechanism in Qt, and the lack of support for being able to remove layouts from grid layouts.... i just... gave up and made a beeline for webkit... the point is: once i had pywebkitgtk working, it's only been three hours and i have the Mail.py example almost fully working already! (what's the other possibilities?) there exists some _really_ exciting tantalising possibilities with this, which takes a bit of explaining. the first time i saw pyjamas, i went "cool! a web-based widget set that looks like a desktop widget set. i wonder if it can be _made_ to be a desktop widget set?". then, i saw that llampies - one of the pyjamas developers - had ported pyjamas to gtk. i got really excited, only to find that _actually_ what he'd done was the OTHER WAY ROUND: he'd ported _gtk_ to pyjamas! http://code.google.com/p/pyjamas/wiki/GsocLlpamies llampies, basically, has written "wrappers" - alternative implementations of gtk.py, glib.py and gobject.py, which get compiled with the python-to-javascript compiler, pyjamas, along with your pygtk2 app, to run your pygtk2 apps UNMODIFIED as *web* applications. so, you write your app as a python-gtk app, you compile it up using pyjamas, and it runs as a web application. even though it's actually python-gtk-compliant source code. bear with me whilst i outline why that work is so significant. take a python-GTK application, and run it through pyjamas, and it's a web app... but if you run it under pyjamas-desktop, it runs ... as a web app. (that doesn't sound significant - in fact it sounds mad. you're taking a desktop app and running it... err... on a desktop, adding massive overhead and missing out bits of the pygtk2 API as well, _and_ you're limiting me to the subset of python that the pyjamas compiler supports!!!) whooa, hold your horses - it sounds mad... until you remember earlier that i mentioned the possibility of running webkit under python-qt4 if someone writes the bindings. and running webkit under python-wxwidgets if someone does the python bindings for that, too. so... you get to write an app as a python-gtk2 app, conforming to the pygtk API, and... through pyjamas-desktop/webkit with llampie's gtk2 wrappers, you get to run your python-gtk2 app UNMODIFIED in a qt4 environment. or a wxwidgets environment. or... any-other-kind-of-environment. including a web app, remember, if you dump pyjamas-desktop and just use llampie's compiler. (wow!) yeah. (it's still madness) yeah. quit bitching about it. oh - and you _should_ be writing your apps to conform to a MVC framework _anyway_, so there's no need to complain about being limited to a subset of the python library. you have JSONRPC (yes, i've written a JSONRPC proxy, which is a useful JSONRPC client library in its own right), you have pimentech's JSONRPC server-side django plugin, so you can write the front-end in a limited subset of python (it's not _that_ limited) and get it to talk to the back-end, which happens to be running on loopback HTTP as a twisted app or a django service, where you have full and complete access to the entire range of python libraries. and, then, if you're ready to make it a web app, compile it to AJAX with pyjamas and... well... that's it. you're done. and your code is nicely subdivided into front-end, back-end, just the way it should be. if you made it this far, thank you for reading. if you helped make the glib bindings happen, thank you once again. if you would like to see qt4 webkit DOM model bindings happen, contact me and we'll discuss it. if the webkit glib DOM bindings prove useful to you, financial contributions would be very welcome. if you're not in a position to do that, your blessings and gratitude will do just as well. l.

Hi All, i have posted this before but didn't get the reply thats why i am posting again. After running WebKit i am stucking at WebKitWebView* webView = WEBKIT_WEB_VIEW(g_object_new(WEBKIT_TYPE_WEB_VIEW, NULL)); function whose defintion i am not getting in the source code and due to this i am unable to do any progress. The function called after this are never called because WebKit hangs in this function. Somebody please help me in telling where is the definition available so that i can move ahead this stucked point. Thanks and Regards Nishit Sharma
