Like I mentioned before, I will spend the next few days in Florence (Italy) for PyCon Italia. I’m preparing my slides and demos, including few things I never posted before (premier show, yay!), for the Advanced Graphics Programming with PyQt talk.

Seems that the trick to make a transparent QWebView or QWebPage is not very well known. So here is the magic incantation:

Fresh from the oven: Qt 4.5.1, Qt Creator 1.1, new SDK.

This is the follow-up to what I wrote before: hue subdivision for mortals.

The use of HSV/HSL color space is obvious when we need to have several colors distributed in an optimal way, colors as unique as possible. For example, SpeedCrunch uses it to autogenerate the colors used for the syntax highlighting feature. The details behind its algorithm was already described by H...

It’s been one year I work for Qt Software (nee Trolltech). Two big releases: Qt 4.4 and Qt 4.5. Qt for S60. LGPL-ed Qt. Graphics Dojo. Going to Munich and Redwood City for DevDays. Things are exciting as ever.

In case you miss it, Benjamin just added Google Suggest to Arora, within hours after I showed how to do it in Qt Labs. His BSD-licensed Google Suggest implementation is very lightweight, it is pretty trivial to integrate it to most common applications.

Two (old) tricks for the price of one. Well, since it takes two to Tango anyway.

The initial version of WYSIWYG editor based on QtWebKit (see my post on Qt Labs for details) apparently works pretty well. There are rough edges here and there, something which need fixing, but overall I am quite happy. Live editing a web page opens a whole new possibilty. For an HTML-based help sys...

Readers of my blogs might notice the remark “heavy corporate bias” [1] which was the most interesting comment after I showed the result of JavaScript benchmark test. Interesting? Because I work for Nokia [2] and none of the product shown in that benchmark result is from Nokia. Of course I am not stu...

A dish that is on the prominent position of my must-eat list (when I am on vacation) is sate kelapa (or in its local variant known as sate kelopo). This is like the usual satay, except that it is sprinkled with coconut rasp (hence the name, kelapa is coconut) before being grilled, thus giving its di...

Let’s start with the screenshot (aka the proof):

It is cold. It is snowing outside. It is weekend time. What would be better than baking something delicious?

Today (three-three-nine, no conspiracy about the chosen date, please!) Qt Software releases Qt 4.5.0!

QTimeLine is a nice class to control animation [1], used among others in Plasma::Animator. There are some curve shapes available for the timeline, from a linear one to some easing combinations. Though linear gives a rather standard movement effect, using easing often can give a better touch. This ma...

Approaching the Qt 4.5 release, in order to relax the atmosphere a bit, and while I was just back from vacation in Indonesia, last week I brought nice goodies to the office. Read what I posted to our internal list:

After the recent public beta release of Safari 4, it is time to do another round of JavaScript performance testing (see the last one I did). Here I compare the unstable/development releases of different web browsers, when running SunSpider benchmark (runs/minute) and V8 benchmark (raw score). The te...

Travelling around Sidoarjo, East Java? Drop Steak Liana a visit (located across the train station) and enjoy its rather well-known roasted ribs (Indonesian: iga bakar) for less than EUR 2 per portion.

If you happen to visit Malang (East Java), do not skip the chance to visit Bakpao Telo right in Lawang, a small city just before Malang. The shopping complex is located conveniently on the main street, its enormous size makes it impossible to miss. What is unique there? A lot of assorted snacks (cak...

Remember what I wrote about Qt 4.2 back then? Well now KDE 4.2 also reached it. Rock on!

Qt, the application framework from Qt Software is written as Qt (capital Q). It is not written as QT (capital Q, capital T). QT can refer to a lot of other things, e.g. Apple QuickTime.

Qt::CheatTransform was supposed to be a joke in Qt Developer Days graphics talk (though some people took it seriously). It still resembles the idea of blazing-fast by cheating whenever you can. Basically this is about creating a thumbnail preview of a large image in an optimized way. Downscaling an ...

Klug zu reden ist doch schwer, klug zu schweigen noch viel mehr. English: To talk cleverly is difficult, to hold the tongue cleverly is even more.

Let us start with a comparison (longer is better):

You would know someone better, not from the way he treats his friends, but rather the way he deals with his enemies.

Using WebKit, it is quite trivial to create a tool that grabs the contents of a web page and then saves everything as an image. Together with the new full page zoom feature, we can have the zoomed in or zoomed out version of the page, even at different viewport sizes (which may simulate different sc...

Sebastian just announced that Qt 4.5 will be also available under LGPL 2.1. Yes, it’s the Lesser General Public License (check the FAQ). It means a good change for KDE as well.

Let us start with a screenshot:
