First of all, I'm quite new to Qt. About 1 month of learning the framework, so sorry if the questions are too vague.
I'm planning to use Qt as the framework to support the migration of a legacy system, that is non-unicode and WIN32 API calls exclusively.
So the benefits are many I know, so right now I'm trying to find replacement for the very basic functionality the WIN32 API offered (non-gui) like, files, threads, networking, serial communication, etc.
The first thing I haven't found a direct replacement is for File Locking, which is essential as the legacy system has a tiny Database engine, and we use the Locking mechanisms of "LockFile" win32API Call where we could even lock certain bytes of a file to enforce different isolation levels.
Searching the web, I found references to the Qt Class "QtLockedFile". But now it is not included in the SDK. So I thought it had been deprecated and something new created, but apparently not. I found it as an add-on called "Qt Solutions archive" ( http://qt.nokia.com/products/qt-addons/solutions-archive/index )
But then on a blog explaining changes to future Qt versions ( http://labs.qt.nokia.com/2011/05/12/qt-modules-maturity-level-the-list/ ), it is said all this classes are deprecated.
Can someone tell me if there's a replacement to QtLockedFile and QtService? What would be the best thing to use?, (I need exactly the functionality these classes have). Why were they removed from the SDK?
Thank you all in advanced for your comments and suggestions
