\title Model-View Server
\examplecategory {Connectivity}
\brief Developing a simple server program that displays and makes changes to a QTreeView
which is made available on a Remote Objects network.
\ingroup qtremoteobjects-examples
This is the server-side application that accompanies the \l {Model-View Client}.
\snippet modelviewserver/main.cpp RegistryHost setup
We start by creating a QRemoteObjectRegistryHost with which other
Remote Objects will connect, be registered and then be advertised by.
The model we create can then be easily acquired from the client side by just
connecting to the registry.
\snippet modelviewserver/main.cpp Model-creation and role-selection
Now we have to create the model we need. The exact implementation is
available in the source code, to which you can navigate by pressing the
link further down on this page. We also define which \e roles we want to
expose to the \l{Replica} on the client side.
\snippet modelviewserver/main.cpp Model-remoting
Here, we create the QRemoteObjectHost that connects to, and shares all its
Remote Objects with, the Registry we created earlier. We then start remoting
the model we just created with the name \c{RemoteModel}. We also pass the
\e roles argument here.
\snippet modelviewserver/main.cpp TreeView-creation
We then display the model with a QTreeView widget.
\snippet modelviewserver/main.cpp Automated actions
For the sake of keeping the example light-weight it performs some
automated actions to affect the model shortly after the server application
launches. These changes can then be seen on both the server and client side.
You can also change the text in the fields on the server side and see it
update on the client side.
