[Announce] QML Browser - Web browser written using Qt Components Hildon

QML Browser has been around for a while, but now that it is more functional, I decided to give it its own thread.

QML Browser is a web browser written in QML, using the Qt Components Hildon APIs. Specifically, the UI utilises the org.hildon.components module, whilst the browser code uses components from org.hildon.webkit. The UI is modelled on MicroB (may as well copy the best :)).

Version 0.6.0 of QML Browser is available from extras-devel. The source code is published at https://github.com/marxoft/qml-browser. The source code for Qt Components Hildon is published at https://github.com/marxoft/qt-components-hildon.

Features currently implemented:

Multiple browser windows.
Bookmarks.
Recent/complete browsing history, with access via swipe from right.
Text selection using a mouse pointer (swipe from left to show the pointer).
Zoom using swirl gesture or double-tap (needs fine-tuning).
Find on page.
Standard keyboard shortcuts for new window, reload, show/add bookmarks, find on page, copy/cut/paste.
Configurable search engines. Search engines can be added in the UI, or by manually editing /home/user/.config/QMLBrowser/searchengines.conf.
Custom URL handlers. Handlers can be added in the UI, or by manually editing /home/user/.config/QMLBrowser/urlhandlers.conf.
Download management.
View source.

Some features not yet implemented:

Activate links using the mouse pointer.

Code:

[Display Name]

icon=searchengineicon.jpg // optional

url=http://searchengine.com/search?q=%QUERY%

Adding URL handlers manually.

The config file for URL handlers uses the following format:

Code:

[Display Name]

regExp=http(s|)://somewebsite.com/.+ // Used for matching links

command=my_application --do_stuff %URL% // Executed when a matching link is clicked

The command can be anything you like (invoke application, custom script, dbus-send etc).

Re: [Announce] QML Browser - Web browser written using Qt Components Hildon

Do you think it is possible to customize the main bar buttons or add missing actions to a submenu that substitutes the back arrow? In that way the left finger would manage reload, new tab..ecc..

Out of curiosity:
I have always wondered if instead double click to zoom the full web page just to click on the proper page number of a thread... it would be possible to manage a "one click and half action" to zoom just a zone of a web page using some kind of lense effect with a crossair to pick the right link..
Probably the development effort would be much more than the advantages, but i have always asked myself why no one is using such kind of trick into mobile devices.

I've noticed that Google Chrome on Android does exactly this whenever you tap on a region of a page with multiple links close together. (They don't have a crosshair, but otherwise it works the way you describe.) I dunno if other browsers have this feature...

Well, there are keyboard shortcuts for those actions. If you are going to raise a submenu from the toolbar, then that would be no more efficient that raising the main application menu and choosing the action from there.

Like Opera Mobile? To be honest, I have found that to be one it's more irritating features. No matter how precisely I tap on a link/button, Opera Mobile nearly always forces me to tap it again after zooming in. It's the new 'clippy'.

However, it is possible to do it, though it would require some more features of QtWebKit to be exposed to QML (which I intend to do anyway). It can be done by intercepting the tap and performing a hit test to check what content exists at the position where the tap occured.

Re: [Announce] QML Browser - Web browser written using Qt Components Hildon

Well, such "lens" feature in google chrome for android seems to be called "Link preview" ...but i'm not sure of the exact behavior of the function.
http://www.mobilexweb.com/wp-content...2/02/links.png

I have tried the qml-browser with acid test (gives 99/100) and a few pages filled with javascript: is working really fast.
There is some glitch switching fullscreen and back where sometimes you obtain a completely white screen forcing you to kill the app.
Also history has some issue since it goes back to the first page instead of the previous one and seems hard to activate.
Select-copy-paste works perfectly.
General behavior is a really promising stock browser alternative.

Do you think it could manage also flash plugin?

https://developer.mozilla.org/en/App..._open_web_apps
https://developer.mozilla.org/en/Apps

so it is nothing special just a good browser can do i think and it can be a nice addition to qml browser as there are many good open web apps like here maps line facebook twitter music radio and oter popular games and apps maybe the n900 can handle most of them (600mhz) as they dont seem to be resource hungry on my single core netbook:)

Great work!
I installed via apt-get and got
sh: can't create /home/user/.config/QMLBrowser searchengines.conf: Permission denied
too, i created the file and after that reinstalling worked.

I tried to benchmark via sunspider 1.0.2 , but it fails at 4 or 3 with:
QNetworkReplyImpl::_q_startOperation was called more than once

anyone has some results or the same error?

i got it loud and clear sorry for the trouble:(

basicly i wanted here maps :p

it could be nice if the bottom bar and the topbar could be hidden by a downward swipe on the bottom bar when loading might sound odd but in 2g complete page load times are awful and able to hide them would provide more real estate for browsing while the page loads or when a link is clicked and i am still browsing that page :)

Anyhow, I will expose the hit test result API to QML, then give it a try. It will likely require several hit tests to acquire a selection of links to choose from.

Procedure is something like:

Get co-ordinates of screen tap.
Perform hit test on the co-ordinates, to see if there is a link.
Perform hit tests covering several points within some arbitrary radius of the tap.
Display links.

I can't claim any credit for the rendering speed. I'm just using the QWebView widget.

I haven't come across that, but QWebView does sometimes cause issues with painting, so it could be that the window and it's child widgets were not re-painted when attempting to exit from fullscreen.

For me, it behaves exactly like MicroB. It's activated by a swipe from the right edge of the screen, or long-press on the 'back' button. The logic for detecting the swipe is quite fuzzy. If anything, I would say it is too easy to activate.

Yes, but the QWebSettings::PluginsEnabled attribute is disabed by default, so I need to enable that first. I will provide more comprehensive settings in future updates (and also view-source etc). The APIs are there, I just need to implement them in the application code.

There's some documentation on the QtWebKit plugin support at http://qt-project.org/doc/qt-4.7/qtw...9-dc75fc65d6b6.

No, I've tested against stock PR 1.3 with Qt 4.7.0 in the SDK, and CSSU with Qt 4.7.4 on the device, so it should work fine. :)

I'm not keen on the swipe gesture, but I can keep the toolbar hidden during loading when in fullscreen mode. :)

You can ignore that output. For some reason, QNetworkReplyImplPrivate::_q_startOperation() is called twice when the first network request is made using QNetworkAccessManager. The function returns immediately in this case, so no harm is done:

Code:

void QNetworkReplyImplPrivate::_q_startOperation()

{

    // ensure this function is only being called once

    if (state == Working) {

        qDebug("QNetworkReplyImpl::_q_startOperation was called more than once");

        return;

    }

    state = Working;



    // note: if that method is called directly, it cannot happen that the backend is 0,

    // because we just checked via a qobject_cast that we got a http backend (see

    // QNetworkReplyImplPrivate::setup())

    if (!backend) {

        error(QNetworkReplyImpl::ProtocolUnknownError,

              QCoreApplication::translate("QNetworkReply", "Protocol \"%1\" is unknown").arg(url.scheme())); // not really true!;

        finished();

        return;

    }



#ifndef QT_NO_BEARERMANAGEMENT

    if (!backend->start()) {

        // backend failed to start because the session state is not Connected.

        // QNetworkAccessManager will call reply->backend->start() again for us when the session

        // state changes.

        state = WaitingForSession;



        QNetworkSession *session = manager->d_func()->networkSession;



        if (session) {

            Q_Q(QNetworkReplyImpl);



            QObject::connect(session, SIGNAL(error(QNetworkSession::SessionError)),

                             q, SLOT(_q_networkSessionFailed()));



            if (!session->isOpen())

                session->open();

        } else {

            qWarning("Backend is waiting for QNetworkSession to connect, but there is none!");

        }



        return;

    }

#endif



    if (state != Finished) {

        if (operation == QNetworkAccessManager::GetOperation)

            pendingNotifications.append(NotifyDownstreamReadyWrite);



        handleNotifications();

    }

}

Re: [Announce] QML Browser - Web browser written using Qt Components Hildon

tried it on my N900. Good efforts marxian. like all your other apps this one is also amazing. One question when loading pages why it triggers 100% cpu usage ? and when its done loading CPU usage goes down again. Bug or its like this ?

There's a small issue with the package installation:

Code:

...

-sh: can't create /home/user/.config/QMLBrowser/searchengines.conf:

Permission denied

...

The folder .config/QMLBrowser belongs to root and the file tries to be created as user.

Yes, I see the problem now. There are two image files installed to /home/user/.config/QMLBrowser. Therefore the directory is created as root before the postinst script is run. I will fix this for the next release. :)

Yes. After it "crashes" the sunspider tab, im back on an empty start tab.

Anyway javascript performance seems to be much better than stock, because google maps is useable in browser now :)

I agree on same ui standards but wont it be better to avoid implementing microb ui 'mistakes' into qml browser? Like having add bookmark icon on toolbar is pointless since its already on context menu (and its better there) so a forward page (which is wierdly enough not even present in microb) will be of more use there, also bookmarks can be on menu and reload page can take its place. The enter address field's area (and its arrow area) and toolbar are taking some unneccessary space imho like microb (see attached image), enter address field should be like its on opera mini (on the slim terms i mean) the down arrow icon can be a bit smaller too (like the reload icon on opera mini perhaps?), itll help slimming down toolbar (would be great if it could be almost as slimmer as opera mini's bottom bar) which will look better and maybe even create some space for webpages and maybe even for a extra icon (which can be menu?). On starting the browser, instead of opening a seprate bookmark type window (which it currently opens, and i can see no sense in that) it could open only a "about:blank" in a normal browser window (would be much better). Also history can be on menu instead of right swipe, left swipe to bring mousemode for copy text on page makes more sense in context menu as "Select text" or something. These are my suggestions, what my point is instead of a 100% clone of microb, qml browser can be a improved microb.

Interesting - the short WebM clip on http://neo900.org/news/neo900-progress-update-march works in QML Browser on my device.

Is it some part of JavaScript API that's not supported by this version of QtWebKit?
