How to set up a desktop development target to contribute to Nemo apps

Posted by kypeli

If you want to contribute to the Nemo Mobile apps, you might feel like me in the beginning: a bit lost about where to start and what's needed in order to set up a development environment. Nemo has already quite a detailed wiki page, but I felt like something was missing for a n00b like me. But thanks to w00t I managed to set up a development environment on my Ubuntu desktop so that I can compile and run the Nemo QmlContacts  application. This blog post will hopefully clarify what's needed in order to contribute to Nemo apps in general. Oh, and this is for Ubuntu Linux. In this blog post I will only go through installing the QmlContacts application. But I imagine the other Nemo apps requiring similar steps.

Sunday evening fun: Windows Phone 7 styled progress indicator in QML

Posted by kypeli

I started a new coding hobby project today. But instead of actually getting very far with the productive part of the project I got side tracked on something fun I wanted to try out (don't you just love when that happens 🙂 That's not possible when coding at work...). I wanted to share this day's outcome with you. Let me introduce this humble video show casing a Windows Phone 7 styled loading indicator in QML 🙂 You can get the source code for this small thing (GPL licensed) from here:

Porting MeeGo Qt Components apps to Symbian

Posted by kypeli

Of course I don't have all the answers to what needs to be done for any given MeeGo Qt Component based application to have it running on Symbian, but I think I have three general actions that need to be done when porting an app from MeeGo to Symbian; have it run with the resources, make the code compile and tweak the UI. Thanks to Symbian Annan both MeeGo and Symbian run Qt 4.7.4 with Qt Quick and Qt Components which is of course the reason why this kind of porting is even possible with a reasonable effort. As I wrote in my earlier 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.

I passed the Nokia Certified Qt Specialist test

Posted by kypeli

I just have to put it out here; I am now a Nokia Certified Qt Specialist which means I have the right to use the logo below. I have no idea where I would use it in the future, so let's have it at least here on my blog 🙂 It's nice to be able to join the club of Qt experts. Under NDA I cannot speak about the test itself, but I can tell you that it had some tricky questions as well 🙂 But please instead poke me about any Qt question!

A MeeGo developer’s endeavors to the Symbian Qt world

Posted by kypeli

I've been working with Qt for a while already and we all know what a great cross-platform framework it is. When Nokia bought 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.
