I am trying to implement Dbus client. Dbus server is actually implemented by a third party and I do not know what bindings does it use (but I guess gdbus). Now can I use QDbus bindings in my client application irrespective of whatever bindings used in Dbus server? If so, how are the data types (w.r.t. complex data types/user defined structures) managed between server(e.g. glib types) and client(e.g. qt types)? Explanation of this concept would be greatly appreciated.

All types on the DBus have DBus types, the bindings simply translate them into their own format. For example, a uint32 type is an unsigned int in C/C++, and in the Java bindings it's a UInt32.
Basically, all implementations need to know the wire format of the message. As long as they understand that format, it doesn't matter what higher-level data type that is translated to. I wouldn't really call them complex data types, because you can only send basic data types across the bus.
