Thanks for the pointers.

So:-

Quote:
Nokia today released Qt 4.6, the latest version of the cross-platform application and UI framework. Featuring new platform support, powerful new graphical capabilities and support for multi-touch and gestures, Qt 4.6 makes developing advanced applications and devices easier and more enjoyable.
Quote:
Qt 4.6 includes support for the Symbian platform for the first time, and also adds Windows 7, Apple Mac OS 10.6 (Snow Leopard) and the upcoming Maemo 6 to the list of Qt supported platforms. Also available is community support for real-time operating systems QNX and VxWorks. Support for Maemo 5 is also currently in development, with the second technology preview being released today.
QT4.6 is a cross platform development platform?

Do I need it in order to run apps that have been developed on it?

Is there some kind of write once, run anywhere ethos behind it?

Yes
Correction, QT4.6 is a cross platform development framework

Yes, its installed as a dependency automatically when you install QT based apps.

No, it's more like "write once, compile anywhere".

He means that you write the code once and then recompile it so that it works on different platforms. I guess Qt takes care of the rest.

Re: Qt4.6
 
Ah, hence the multi platform support. So a piece of software written on a windows 7 machine could be compiled to run on a N900.

And how difficult is it to recompile for different platforms?

No idea actually. I don't know much about programming, but judging by pycage's post it seems very easy.

its not a mammoth task to keep the explanation simple.
Its not like rewriting your entire app or logic, however it might involve a few minor code changes if some platform specific coding has been done by the developer.

For example calling some platform api to list files.
its dir in windows, ls in unix

but to keep it simple, its a boon for a dev to have platform independent frameworks, so he just needs to spend time on his idea of creating the app and programming.

Thanks for the input gents.

Whilst I don't really understand how to develop with QT4.6, I at least now know why it is a good thing.

I asked this a friend of mine who knew about this stuff and first he said "w-w-w-dot-google-dot-com" and I slapped him and he said something to the effect of: "If your phone OS supports it, and the next best thing come sout supporting it, your phones can atleast use the same applications."

I think that makes sense and is correct, right?
