12Dec/117earlier blog post, even though both Symbian and MeeGo run Qt and Qt Components, it's not perfect. I think too much manual work still has to be done, but it's a reasonable effort and when you read through my hints, I think the tasks ahead become clearer.
6Dec/117bought Trolltech in 2008 it was clear that Nokia wanted to make Symbian development easier. However, the QWidget based toolkit would not fly on Symbian, or any other mobile platform for that matter, so Nokia built some mobile UI frameworks on Qt (and oh boy Nokia is good at building frameworks for everything. Everyone should have at least one framework, if not two. I could write another blog post about that...). But while people in Europe were fighting over their frameworks, it was not until the guys and gals in Brisbane came up with QML when everything changed. Qt could finally be cross platform again and in an elegant way! Symbian just isn't my cup of tea. But that doesn't prevent me from wanting to write something for Symbian if for nothing else other than being able to say I've done it. But just thinking of Symbian C++ or Avkon makes me feel sick. This has changed thanks to QML and especially Qt Components. Also Nokia has finally been able to put out a single SDK that I can just install, write Qt with, deploy the same code on any Qt-based Nokia mobile, publish in the Nokia Store and... Profit! Right? Well, my opportunity to find out came now thanks to my podcast application, Podcatcher for N9, that I've written for the Nokia N9 smartphone. It's has a MeeGo Harmattan Qt Components based UI with a Qt C++ middleware. These are my comments as a former MeeGo developer on the journey to the Qt world of Symbian.
18Sep/115you should not do that). But before you do that, you should take a look at Qt Concurrent and what it can offer. There is a good chance that what you need is already provided by the Qt Concurrent framework.
How I added threads to my app in 20 minutesIn this post I want to show you how I added threaded database access to my small podcast application for MeeGo, Podcatcher for N9. The use case I had at hands was that I added automatic cleanup of podcast episodes to Podcatcher for N9, which required some heavy database and filesystem access. This is the (naive) code (in short) that I originally had when cleaning up podcast episodes: QList
