The major interfaces that are used in the client – server architecture within DXP are:

IClient shell and its interfaces:

• ICommandLauncher (deals with client’s process launchers table)

• IProcessLauncher (deals with launching a server process from the client)

• IServerDocumentView (deals with panels or server documents)

• IProcessControl (determines the level of stacked processes)

• IGUIManager (deals with the User interface of DXP, the locations and state of panels)

• IServerModule (deals with a loaded server in DXP)

• INotification (Client can broadcast or dispatch notification messages to servers or to a specified server)

DXP’s configuration interfaces:

• IServerRecord (collects servers information at DXP’s start up – not loaded servers)

• IServerWindowKind (determines which document kinds open in DXP)

• IServerProcess (contains the information of a current server process)

IServerModule interfaces represent loaded servers in DXP.

An IServerModule interface has the following interfaces:

• ICommandLauncher (deals with a server’s processes table)

• IServerDocument (represents a loaded design document in DXP)

• IServerView (represents a panel that can have a view of the DXP system)

• IServerDocumentView (deals with a document view (either the document window or panel window))

• IExternalForm (represents a DXP aware Delphi form either as a document form or a panel form. These forms are wrapped by the IServerDocumentView or IServerView interface object. This IExternalForm interface object has low level methods such as resizing and displaying the form)

• IProcessControl (represents the level of stacked processes for this focussed server document)

• INotification receive system notifications from the Client system and all server modules receive these notifications. There is an ability to handle a notification and take it from there. Documents and associated panels can be synchronized through the use of notifications as well).
