How to implement SMS on Maemo5 using Qt？

[grasssu]

Hi,
I'd like to develop some applications for my N900 using SMS. I'm very new to Qt and Maemo and don't know where to start. I've just installed the Ubuntu Maemosdk image in a virtual machine. Could anybody point me to the SMS programming tutorial of Qt? The documentations don't look so clear to me, as I don't program in GTK+, all I wanted to know is a complete direction of using Qt only, including installation and development. Please help！

Thanks,
Grass

Qt doesn't have any specific means for handling SMS. This is done through other components. As far as I know, at the moment there are no publicly available information about handling SMS in Maemo 5.

To install basic subset of Qt packages in scratchbox:

apt-get install libqt4-dev libqt4-gui

To get the whole list of Qt packages:

apt-cache search libqt4

There is a tutorial for a very beginners in Qt:
http://doc.trolltech.com/4.3/tutorial.html
and of course there are books available.

Hi,

I need to send SMS and register of incoming SMS notification on N900.

QT 4.6 contains QDBusMessage class. Can we use this class to send SMS?

If not, is there any alternative approach to send SMS using telepathy library?

Thanks in advance

You can use DBus directly if you know what closed interfaces are.
You can do the same using Telepathy. But approved way in Qt is to use
Qt Mobility Messaging library
http://qt.nokia.com/doc/qtmobility-1...messaging.html
Note, it's still a technical preview.

Hello Daniil,

Thanks for the information regarding Qt Mobility Project.
I assume apps developed using Technical Preview, can be uploaded to Ovi store.

Thanks again

I guess not yet, but you can make it clear asking here:

In the following links there are some information regarding interfaces to be used,
http://wiki.maemo.org/Documentation/..._in_Freemantle
https://garage.maemo.org/plugins/wik...id=1106&type=g

Example, from my understanding the interface required to send SMS is com.nokia.csd.SMS.Outgoing.

So when you say closed interfaces, do you mean the same interface name?
Or is it something to do with licensing or certification?

Thanks

The term closed means that they are not public. The link above contains reverse engineered information. There is no licensing or certification as far as I know. It's obviously beneficial for Qt application developer to utilize Qt Mobility, as this is high level abstraction, however, I don't think Ovi store supports features at the stage of technical preview.

According to following link of QT mobility Technical Preview 2,

http://qt.nokia.com/doc/qtmobility-1...wn-issues.html

it is given,

Maemo Specific
* Messaging backend for Maemo is not yet implemented.

So i wonder if messaging is supported in QT mobility for Maemo in the current tp2.

[divanov]

Probably not:

So DBus or telepathy are the remaining options. :-(
