\title Example 2: Direct Connection with a Dynamic Replica
\brief Describes how the Qt Remote Objects establishes a direct connection with a dynamic replica.
\target qtro-example2
Initially, a dynamic replica is created as a "bare" QObject - without
properties, signals or slots. Then, during initialization, QtRO returns the
API for the object, after the connection to the source is made. Thus, the API
is added to the object at runtime.
There are no changes to be made on the source side, as a dynamic \l Replica
only impacts how the requestor node acquires the replica. So, we use the
source-side code shown in \l {qtro-example1}{Example 1}.
\list 1
\li Add replica generation to the project.
Because the replica is dynamically acquired, no \c .rep file is
required unlike in \l {qtro-example1}{Example 1}.
\li Create the remote node and connect it to the source host node.
The code for this step is unchanged from \l {qtro-example1}{Example 1}.

\li Acquire a replica of the remote source object.
In \c main.cpp, we use a QSharedPointer to hold a replica of the
remote object, and then instantiate a replica requestor object:
\snippet doc_src_simpleswitch.cpp simpleSwitch_dynamicclientmaincpp_example2
\endlist
The complete declaration and definition of the requestor class,
\c DynamicClient, is as follows:
\c dynamicclient.h
\snippet doc_src_simpleswitch.cpp simpleSwitch_dynamicclientheader_example2
\c dynamicclient.cpp
\snippet doc_src_simpleswitch.cpp simpleSwitch_dynamicclientcpp_example2
When run together with the source-side example, the output is identical
to \l {qtro-example1}{Example 1}.
