3rd Party Software

I am happy for help you. :)

QX11EmbedContainer seems to be only available for linux but I am trying to stay on a Windows platform for this project.

Do you know of an equivalent QX11EmbedContainer class for win 7?

i successed to compile the mysql driver for qt4.8.1 with mingw and it work for me very good ^^, i hope for you too.
this a link to the qsqlmysql4.qll, qsqlmysqld4.qll, http://www.mediafire.com/download.php?z1e1ypqhqc96icn.
just to tell you, i compile under windows 7 64 bits, mysql-5.5.25a-win32.
after downloading this two dll files copy them to you sqldrivers folder (for me is :C:\QtSDK\Desktop\Qt\4.8.1\mingw\plugins\sqldrivers) then copy the libsql.dll ( you find it in your mysql's lib directory for me is : C:\MYSQL\lib), and paste it in your project directory, and it will work , well i hope so because it work for me like this ^^

I execute the compiled app with root user and then works the open method()!

Can I make this works with a normal user?

I think they are from compiler here is an example:

and they continue for thousands of lines...

If you want to see all messages, I uploaded the output from make on my server: http://tiago.eti.br/make_output

For a test you can use the demo on the site, you can create your report and print on pdf,image, and many more. But for using in your application you need buy the annual license.

How can I get windows version of qwt in my ubuntu? Is there some procedure how can I do that? thanks

I am also interested in changing the playback speed, but as far as I know it is not possible in Phonon.

The phonon backends should support this easily, so I don't know why this is not part of the Phonon API

Anyone know more about this issue?

I think there are just many implementations of the same idea. The coverflow idea (patented by Apple? Not sure on that one) was picked up by others after Apple introduced it on the iPod touch rather quickly by others, who came up with their own implementations. There are also examples on how to build one using QML (quite simple, actually), and even libqxt has a "widget":http://libqxt.bitbucket.org/doc/0.6/qxtflowview.html#details in the library implementing the idea.

So, you adhere to the licence of the implementation you use, and hope Apple did not patent it or can't be bothered to go after you.

The Microsoft one...
And it's Boost 1_47 I use.

It is working in linux.

maybe in gSOAP? look with wireshark into Request Headers from your app.
