I've always wanted to add a function that uses Apache's Batik for SVG export. However, it will be some kind of add-on rather than a part of the core release, because I don't want the Quick Sequence Diagram Editor to be dependent of numerous libraries just for the sake of a single export function.

I think that it would rock if you implement it as a command line tool - which produces an SVG/PNG/image by proceeding stdin or input file.

There will be a new version released soon. It consumes significantly less memory than old versions, is faster and allows for the processing of arbitarily huge diagrams.
The feature you requested may well be implemented once the work on that version is done.

Yeah, this editor is realllly great.
There's only one small thing:
You can't send a message after the "//"-comment block without being included in this block. Example:

block start 
message in the block 
block end 
message to send after the block

You know what I mean ? This might be good to be fixed in the next release.
Thanks a lot for this great piece of software !

Yes, I've never been happy with the comment blocks, and there should be a better solution sooner or later. Right now, however, I cannot tell when this will happen.
Until then I suggest, as a workaround, to insert a self message (with possibly no text) right after the comment line. The answer to this message should be sent when the end of the block to be commented is reached. By the way, this "technique" is used in the BFS example.

Hi, the sequence editor is great.

Thanks for the editor,

Please take a look at my notes on asynchronous messages.

I'd like to think that "calls on itself" are supported very well. Except for actors, but actors can do simple actions:

john harris <tamboril3 {AT} comcast {DOT} net> wrote:
If actors can only send async. messages, then why are there return arrows for those messages?

They are there because earlier versions Quick Sequence Diagram Editor did not support multithreading. The return arrows signalled the end of the synchronous activity started by an actor.

When multithreading is enabled, messages sent by actors are interpreted as messages that spawn threads. So return arrows may seem to make less sense now. Thus, as of version 2.5.5, if the answer to a message sent by an actor is an empty string and "Show answers to actors" is set to 0 in the "Flags" section of the configuration, no such return arrow will appear on the diagram.

Very nice tool!
We are currently using it to display test sequences generated by our testing tool. For the moment we generate the syntax needed by the Quick Sequence Diagram Editor (QSDE), and copy-paste it to its window.
It would be great if the QSDE could be started in a server mode such that one can send this syntax to it via a socket, and then the sequence diagram is displayed.
This could be even improved by allowing to send messages one after the other, so that the sequence diagram is piecewise extended. This would allow for real-time diagrams to monitor for instance the testing process.
Thanks for the nice tool! Lars

This feature is included in version 2.6 of Quick Sequence Diagram Editor.

Second, I found an important problem. It doesn't support Chinese! I don't know why, maybe it has something to do with the font. I think Java supports UNICODE, so I hope you could fix it. Thanks very much.
PS. I even hope you could do some class diagram editor or flow chart editor. (All use the same kind of script. What do you think?)

Thank you. I am just a single person. Won't somebody help me? Let's wait and see, but right now there are no plans for other UML editors. You can use UMLet for creating class diagrams from text.
The next version will have a font and encoding configuration. Choosing a font that includes Chinese characters should fix the problem then. It will also support notes (text boxes resembling pieces of papers).

Hi Markus,
The open-source Xholon modeling and simulation tool will include sdedit when version 0.7 of Xholon is released. It works very well at showing the interactions (asynchronous messages) between objects in a Xholon application.
We have tested it with sdedit-2.8.3-light.jar, which has all the functionality that we require. I can't find a light version with release 2.10.2. It would be great if you could make a light version available with future releases, or have I overlooked something.
Keep up the good work.


I believe that most users favour "all-in-one" files, but there is no reason to not offer a light version. So release 2.10.3 - which fixes only very minor bugs - will also be available in light format (approximately 280 KB) without the export library included. Expect it to be released this week.

Hi Markus,
great tool. Thanks!
It would be great to have a simple influence on the time relations (you mentioned this in Todo). A first step might be a possiblity to "close" all open answers before next messages are generated. Together with a separator (like in the fragment section "--some text") this might help to control the timing and clean up some of the diagrams.
This leads to the possiblities: separator (invisible, with optional text) with or without answers to pending messages.
Viele Grüße, Jens

Thank you. As a first approach, it is now possible to "close" all open answers on a given thread (see the "Returning control flow" section on the multithreading page).

  1. Perhaps it is already planned for further versions. Would it be possible to add a "export all" function so that i can generate PDF-files and PNG-files with just one click?
  2. It would also be nice if the whole application would have an integrated explorer on the left. So that i can eassily open the sdx-files on the left.
If i have more ideas or criticisms i will let you know ;-)

Thank you.

  1. A nice idea, even though all export files must be configured in the same way then (no problem for PNG images, of course).
  2. Can you or anybody else give me a hint where to find a decent file explorer component written in Java, published under the terms of the the LGPL, BSD, Apache or a similar license?

Hi! Wonderful software!
A question, please.
How can I make an object become inactive?
Sometimes an object remains active even if I don't want it to. An example:

Mittente:Agente p "Agente Mittente"
Circuito:Circuito p "Circuito"
Destinatario:Agente p "Agente Destinatario"

Mittente:Fornisce Autorizzazione se OK da Mittente e Destinatario=Circuito[a].Richiede Autorizzazione(IDA, IDT, PANM, PAND, IO, ID)
Circuito[a]:Fornisce Autorizzazione=Destinatario.Richiede Autorizzazione (IDA, PAND, IO, ID)
Circuito[a]:Fornisce Autorizzazione=Mittente.Richiede Autorizzazione (PANM, IO, ID)
If I add another message to the diagram, it appears before the first message answer.
Thank you.

You do not provide information about which object should send another message. So I can only guess it is "Mittente". This object has yet to answer to the message received from "Circuito". If you add "[1]" after "Mittente" in the description of the next message, it means that "Mittente" will send one (1) answer before the message. This is probably what you want!?

Mittente[1]:Destinatario.another message

I see someone else had a similar problem to mine: inputting in Japanese works fine, but once I save and reload a file all the Japanese characters are replaced by the UTF8 byte sequences encoded in ASCII. I managed to fix it, and there's only one change needed:
In, change line 99 from:




The problem is that String.getBytes() encodes by default in UCS16, while the InputStreamReader created in DocUtil.readDocument still expects UTF8. So just changing the String.getBytes call to specify UTF8 as the encodes fixes the problem. This should fix any problems with loading files with non-ASCII characters.
I really love this tool, by the way!

Keep up the great work!

Version 3.0.3 allows to declare external processes (process ("p") objects with the "e"-flag set). Internally, they are not much more than process objects that are invisible. They can be placed at any position. This should be sufficient to have "found" messages. See also the "Ticket order" example of this new version.

One question - if you define a synchronous call onto the same component and then have more, subsequent calls to other component, it looks like the termination of the call onto the same component is after the return of the calls to the other components - is this expected behaviour?

Yes. If you want the call to the same component to be terminated before, the first of the calls to the other components should have level 1: caller[1]

Instance is just another word for object, so it does not make sense to create several instances of an object. You can create several instances of a class, say "inst". So write o1:inst, o2:inst and so forth.

Very nice application, very well done, kudos. This has brought down my time to make a quick sequence diagram from hours to minutes.
A couple of small things I have ran into:

  1. How can I create a ref frame over several live lines without the frame containing any messages. If I leave the box empty I get a "there is a no open comment" warning. Also in that case objects not involved in the detailed diagram should have their live lines drawn on top off the frame. Maybe something like: [r:obj1:obj3:obj4 Reference name]
  2. How can I control the activity of messages to self. It seems that currently any message to self will be active until the end, which is not what is wanted for consecutive messages to self for instance.
  3. Object creation is hard-coded to new... it would be nice to be able to specify different messages as constructors.
    And related to that a feature request:
    It would be nice to be able to use flags on messages in a similar way as for Objects. for instance [c] for a constructor [a] for an asynchronous message [s] for a signal etc.

Some good questions, little time to answer now...

P. S.: Export to JPG resulted in a red tinge, I don't know why. I even tried to explicitly set a white background going to options while exporting - still the output was the same. Export to GIF was perfect (white background).
Calling a self-message is forcing an additional return value that comes at the end.

When the answer to the self-message is empty, the returning arrow can be made invisible (see the posting right before yours).
The JPG export bug is well known, but has not yet been fixed. Saving an image in JPEG format from the command line works great, nonetheless.
