If you have worked with QtSql, you might have hit the dreaded “Parameter count mismatch” for your perfectly valid SQL query. The problem is excruciatingly hard to debug because the query itself works perfectly fine with the sqlite3 tool.
Here’s the solution: Compile Qt with -system-sqlite.
The problem: Qt uses it’s own sqlite3 headers under src/3rdparty by […]
Ever heard of WebKit2 and wondering what it means from a Qt perspective? Here’s an attempt to explain QtWebKit and QtWebKit2 in simple terms. I make no attempt to be completely technically correct, it’s meant to be able to explain terminology to the WebKit uninitiated.
In WebKit lingo, “WebCore” is the thing that takes of parsing/layouting/rendering […]
At the Qt Contributors Summit, Johannes‘ showed me his Qt/Caca Lighthouse plugin. Caca is a graphics library to output text instead of pixels. So this plugin lets you run Qt programs on the console
His code needed some love, so I forked it and cleaned it up. Caca does not provide a event fd […]
Up until 3 hours back, I wasn’t intending to attend QCS since my visa was expected to arrive late. We have 15 working days waiting period here just to get to the visa interview phase. My tickets were booked for the 19th June to Berlin nevertheless for a Qt Media Hub hackfest. I attended the […]
Disclaimer: I am an ex-troll and my company does a lot of Qt business with Nokia
I have been reading the largely negative comments in the blogs by Aron and Daniel about the future of Qt. Sigh, the anonymous internet has made it all too simple for people to post abusive comments and suggest conspiracy theories.
I […]
To my knowledge, there are 3 Qt based JSON parsers out there – QJson, JsonQt and this. QJson uses bison for parsing and JsonQt is hand-written. I have used QJson before and it works perfectly fine.
If you are like me, you will sense an opportunity here to write a qlalr based parser […]
Here’s a cheat sheet for all the WebKit repositories.SVN: http://svn.webkit.org/repository/webkit. This is always the latest and greatest WebKit code since SVN is the version control used for WebKit code. To checkout trunk, you would do ‘svn co http://…
I will be attending CES 2011 at Las Vegas. If you would like to meet up informally or to discuss about QML/Qt/WebKit consulting, please send me an mail.
I find this script (notify-me) most useful when I build webkit 🙂
Just ‘make && notify-me’. You will get a tray notification when the build is complete. Code is not mine, it’s ripped from some site.
#!/usr/bin/env python
“””This is a python 2.5 script that creates a notification using dbus.”””
import dbus
item = (‘org.freedesktop.Notifications’)
path = (‘/org/freedesktop/Notifications’)
interface = (‘org.freedesktop.Notifications’)
icon = ”
array = ”
hint = ”
time = 10000 # Use seconds x 1000
app_name = (‘Test Application’)
title = (‘Whatever it is, is done’)
body = (‘Its all over.’)
bus = dbus.SessionBus()
notif = bus.get_object(item, path)
notify = dbus.Interface(notif, interface)
notify.Notify(app_name, 0, icon, title, body, array, hint, time)
I have been away from WebKit development for a while. There were some pressing matters in Maemo6 to attend to.One of the things I am working on is the Flash support for Maemo6. And I am finding that the abstractions of QGV, meegotouch, Qt/WebKit are “a…
