IClient Interface

Overview

The IClient interface (from RT_ClientServerInterface unit) represents the Client subsystem of the Altium NEXUS application and the Client manages the commands (pre packaged process launchers), process depths and documents. The every server module loaded in Altium NEXUS has hooks to the single client executable subsystem, so you have access to the specific documents of any loaded servers and launch server commands.

The IClient shell and its Interfaces;

• ICommandLauncher (deals with process launchers)
• IProcessLauncher (deals with launching a server process)
• IServerDocumentView (deals with panels or server documents)
• IProcessControl (determines the level of stacked processes)
• IGUIManager (deals with the User interface of ALtium Designer, the locations and state of panels)
• IServerModule (deals with loaded servers in ALtium Deisgner)
• INotification (broadcast or dispatch notification messages to servers or to a specified server)

You can obtain the IClient interface object by calling the Client function directly in your script.

IClient Methods

AddServerView method

(IClient interface)
Syntax
Procedure AddServerView (AView : IServerView);
Description
This procedure adds a document view such as a custom panel in the Client object within Altium NEXUS.

IServerModule Interface

Overview
A server deals with its own server documents. There can be different design document types, for example the Schematic Editor has two Schematic and Schematic Library document types.

Each design document, in turn stores views which can be a document window or a panel window. A server has the ability to host multiple panel views for a single document view, see the diagram below.

A server also has the ability to host multiple global panel views that represent some system state and are not necessarily tied to a particular design document (for example the Work-Space Manager server has Message, Differences and Errors panels). This document view / multiple panel views structure is the foundation of Altium NEXUS client / server architecture.

These IServerModule interfaces (from the RT_ClientServerInterface unit) represent loaded servers in Altium NEXUS. This application manages single instances of different server modules. Each server can have multiple server document kinds, for example the PCB server supports two server document kinds – PCB and PCBLIB design documents. A loaded server in Altium NEXUS typically hosts documents and each document in turn hosts a document view and panel views.

The diagram below represents a server module with server documents. Each document has views - the document view and the associated panel view.

Notes
An IServerModule interface has the following interfaces:

• ICommandLauncher deals with a server’s processes table
• IServerDocument represents a loaded design document in Altium NEXUS
• IServerView represents a panel that can have a view of the Altium NEXUS system
• IServerDocumentView (deals with a document view (either the document window or panel window)
• IExternalForm represents a Altium NEXUS 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 and is the ancestor interface for IServerDocumentView and IServerView interfaces.
• IProcessControl represents the level of stacked processes for this focussed server document
• INotification receives 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.

Notes
The PCB server module also has its IPCB_ServerInterface interface.
The Schematic Server module also has its ISCH_ServerInterface interface.
However both servers also have this IServerModule interface.

Document and Panel View Interfaces

IExternalForm

Overview
The IExternalForm interface represents a Delphi form either as a document form or a panel form.  This IExternalForm interface object has low level methods such as resizing and displaying the form.

Notes
The Altium NEXUS platform is based on the object interfaces technology by Borland(TM), thererfore TForm, TFrame, and other VCL controls to object interfaces are not passed into object interfaces that can be exposed to third party development in different programming systems. For example VCL technology is not compatible with MS C++ toolkit.

Therefore to work with windows in the Altium NEXUS platform, you use the IExternalForm interface to have access to windows and manipulate them. The IExternalFormHolder interface and the TExternalFormComponent class are used to work with Delphi windows in a server plugged into the Altium NEXUS platform and accessible to other servers plugged in.

IServerDocument Interface

Overview
The IServerDocument interface represents the document container. Each IServerDocument interface is a document containter made up of views of the same kind.
A view can be a design document form or a panel form.
Every document editor server (encapsulated by the IServerModule interface) that supports creation of documents will have a IServerDocument interface.

The IServerDocument interface hierarchy is as follows;

DoFileLoad method

(IServerDocument interface)
Syntax
Function DoFileLoad : LongBool;
Description
This function allows the re-loading of the document. This is useful if the document has been modified and saved and it needs to be re-loaded to ensure that the document is in the latest state.
Example
See also
IServerDocument interface

DoFileSave method

(IServerDocument interface)
Syntax
Function DoFileSave (Const AKind : Widestring) : LongBool;
Description
This function provides you an option to save the document in a different format if the document supported by the specific document editor provides the option of saving in a different format other than the default format. Normally these file formats are stored in the SaveFilters block within the EditorWindowKind section within a server installation file (with an INS extension).
File Formats
For example with PCB documents in Altium NEXUS, you can save them as a PCB ASCII format, PCB Binary 3 format etc - PCB Binary, PCB 3.0 Binary, PCB 4.0 Binary, PCB ASCII. By default its PCB Binary 5.0.
With Schematic documents, you can save them as a Advanced Schematic binary, Advanced Schematic ascii, Schematic binary 4.0, Orcad SDT Schematic, Advanced Schematic template.
Server Installation files
The file formats supported by editors can be found in the server installation files within the SaveFilters - End blocks.
DelphiScript Example

Var
    Board           : IPCB_Document;
    AView           : IServerDocumentView;
    AServerDocument : IServerDocument;
Begin
    // save the file in a different PCB format
    //check if current document is a PCB document otherwise exit!
    Board := PCBServer.GetCurrentPCBBoard;
    If Board = Nil Then Exit;
    If Client = Nil Then Exit;
 
    // Grab the current document view using the Client's Interface.
    AView := Client.GetCurrentView;
    AServerDocument := AView.OwnerDocument;
    AServerDocument.DoFileSave('PCB ASCII');
    Close;
End;

GetContextHelpTopicName method

(IServerDocument interface)
Syntax
Function GetContextHelpTopicName : Widestring;
Description
The GetContextHelpTopicName function retrieves the help topic name for the document. Normally the returned string would be the ServerModuleName.DocumentKind format for example 'SCH.SCH' Some servers provide more detailed information, for example Schematic Editor server returns Sch.Sheet.Port when the mouse is over the Port object on a schematic sheet.
Notes
Third party developers can use this function to provide context sensitive help.
To implement the help for your server, you should have a .HELPID file in the Help folder where the link between the string returned by the GetContextHelpTopicName and the actual help document is established.
For example the CXTSystemDesignCapture.HelpID contains a Sch.Sheet.Port = CXTSystemDesignCapture.chm,Document_Objects\Port.htm. This means when the F1 key is pressed and the Sch.Sheet.Port string is returned, it will use the CXTSystemDesignCapture.chm filename and display the Document_Objects\Port.htm topic.
