Tutorial on uploading apps to Maemo Extras-devel using Qt Creator and Windows

Raed A has written up a detailed walkthrough of using Qt Creator on Windows to build open source software to upload to the maemo.org autobuilder: I have spent some time trying to upload my first N900 app to Maemo repository extras-devel. Below are the steps needed to upload your app. I am using Qt SDK 1.1 TP under Windows XP. The steps required are from existing resources like posts, links, etc… and some are from my own experience.

Hildon-Desktop running on MeeGo IdeaPad

Two videos show the progress the "Cordia" project is making on bringing Maemo's user interface on top of a MeeGo base. Tomasz Sterna says: This is a basic Cordia's Hildon-Desktop running on Lenovo Ideapad S`10-3t

Whole Hildon Desktop with Hildon Home and Hildon Status Menu running on Ideapad. Tomasz says the aim is to go "far" down the stack of Maemo, "unless there is already a subsystem doing the same in MeeGo". He already has, for example, "osso and skeleton DSME support".

Ultimately, the aim would be to run many Maemo 5 applications on a MeeGo core with a bit of tweakery and a recompile. If succesful, this is the next step for Maemo, after the Community SSU; and developers from both teams are liaising on changes and approaches. If the Community SSU provides a short-term evolution and continuation for users; Cordia may be able to deliver the medium-term solution; whilst MeeGo's own Handset UX and application ecosystem provides the long-term evolution.

How to enable multi-touch on MeeGo ARM? (for Samsung Galaxy Tab)

Simon Pickering has asked for assistance with his port of MeeGo to the Samsung Galaxy Tab, which runs Android by default. Specifically, how to use the multitouch-capable capacitive screen: I've got Meego booting and up to showing the handset "desktop" and understand that I should be able to recompile Qt to support multitouch input events as produced by mtev (currently with mtev I receive no inputs so can't do much other than admire the desktop wallpaper), but I've really no idea which version of Qt and/or the multitouch driver one should use, and which combinations work, etc. If anyone understands Qt and Linux's multitouch capabilities, please help Simon on the mailing list thread.

Input method framework for MeeGo runnable on your desktop

Michael Hasselmann, I've been working on the MeeGo Input Methods project (codename "Maliit") for nearly a year now. The project provides a pluggable framework for input methods. It comes with a reference plug-in for a multi-touch-capable virtual keyboard. It had bothered me that, even though our source code was available at gitorious.org, there were nearly no contributions from the outside. I attribute that to the difficulties when it comes to compiling all required components, but also to the lack of perceived openness. To increase openness, and attract more contributors, packages are now available for Ubuntu. Anyone that's interested in contributing to MeeGo's input framework should probably consider this their cue.

Qt Quick Playground

As part of Forum Nokia's mission to improve developer understanding of Qt, and the best way to build MeeGo, Qt, Symbian and Maemo, an application is available which demonstrates a number of discrete capabilities along side each other: This QML application demonstrates the features of Qt Quick with a set of demos and the possibility to view the source code of the demos. Each demo shows different areas of the Qt Quick features. The application is compatible with the Nokia N900, S60 5th Edition devices, Symbian^3 devices and Windows desktop with Qt 4.7.0 or higher. Binaries, source code, screenshots and an introductory video are available.

Connecting QML buttons to C++ code

Karoliina Salminen has posted a snippet of code from her recent experiences learning QML: I was trying to figure out how to connect button click to C++. Here is very short how.
