Hi every body ,
I am working with QT from last 2 years but I have many Question unanswered
1. what is the architecture of Qt means what are the layers of Qt ?
2. Architecture of the Qt communicate with system (hardware/OS).
3. How Qt application works on system means how the application communicate with system (hardware/OS).
4.How can I know the complete architecture of QT.
How to explain about the architecture of Qt, if one asks?
So Please help.
Thanks in advance !!!

I really can't figure this, what do you call "architecture"? Be a little more specific (the whole architecture of Qt will be hard (if not impossible) to explain in a forum topic, not to mention that Qt is build with modules, so one person that knows everything might not even exist ;) )
And one of many advantages of Qt is that is open source, so if you want to see how a particular piece/class/etc of Qt "communicates" with the OS you can look in the source code and see...
And, an "attempt" of an short answer answer:
Qt "architecture":
â—Built on low level APIs of platform
â—uses native styles to draw UI (Widgets emulate exact look & feel)
â—Cross-platform (Single source for multiple platforms, only requires recompilation)
Hi thanks for your quick reply ,
I got your point it is not easy to know about all the modules architecture.Here I basically want to know how the basic QT application communicates over system(Hardware/OS) and the layer based explanation for an basic Qt application .
Please suggest me either the where can i get all these information.

You should consider Qt as a library. Applications may call Qt methods or OS calls directly.
The meaning of "layer based explanation" is a mystery. Your application communicates however you program it to (or not to) communicate: network sockets, shared memory, files... Where Qt libraries are used as an intermediary they are designed to hide platform dependent methods of doing all of the above.Quote:

The Qt documentation and, if necessary, the Qt code. Both are freely available.Quote:

Afterthought: If by "layer based explanation" you mean "inheritance hierarchy" then that is in the documentation.
