Hello,
I pushed change "I857be0652a852cc69a9729f64e67134fe630af00" to gerrit.
It contains a new model editor plugin I wrote. If you are interested how
it looks like please visit https://wiki.qt.io/ModelEditor.
Note: Patch Set 3 cannot be compiled with qbs yet. I am fixing it right
now.
Regards, Jochen

Depends all on how fast the two related changes are accepted in gerrit
(Qt code review tool) and how long it needs until the next official
release of QtCreator (version 3.6 or 3.7 I assume).

After review done, most wanted peoples can try it via
http://download.qt.io/snapshots/qtcreator/master/latest/ or via
https://launchpad.net/~adrozdoff/+archive/ubuntu/qtcreator-git ;-)

Joched, could you please provide HTTP link to the review?

It and its dependencies is a huge piece of code:-)

Any chance to have vivid packages? Currently I cannot install the trusty
packages since on vivid, there's no libts (broken deps).

Could you tell me where I can download or clone your QtC source tree or
download binaries somewhere?

Thanks a lot for the info.

But I have been unlucky so far, last time the build succeed, but QtC was
visually broken and would crash when trying to access tools->options.
This was at: "6cac3b7 DiffEditor: Add indication on failure"

Have now rebased on top of: "e5f3c55 Static.pro: Remove unnecessary
evals", will see if it works now.

Notice that the plugin is already merged, so you can download the snapshot
installer <http://download.qt.io/snapshots/qtcreator/master/latest/> to try
it out.

Sorry, I have no vivid installed at all and can't test package before
uploading.

You can use official binaries.

Hi Jochen,

Any plan for adding new features?

Random thoughts after using it for a real case:
- print support
- SVG export
- Support for "real" state machine (not activities)

Thanks a lot for this wonderful plugin!

The first two could be delegated to another tool. One could export to
PlantUML <https://en.wikipedia.org/wiki/PlantUML>,
and from there export to SVG etc.

Hi

Instead of implementing an exporter to PlantUML (which in fact would
lead to complete different diagram layout) it is much easier to
implement print support, SVG export and other exporters directly.

I already implemented a small tool which loads a model and exports
diagrams as png, svg or PDF files. Its not released yet but I will do in
future. And I will add functions to export into these formats from
ModelEditor plugin. Printing is also not a big deal.

Today you can print by pressing "Ctrl-C" on a diagram when nothing is
selected on the diagram. This will copy the whole diagram into the
clipboard using 300dpi. Paste it into any program which is able to print
images.

The real state machine is already planned (see Wiki page). Currently the
possibility of having numbered relations is still missing. I want to
implement customizable relations first. After that state machines should
not be difficult.

Sequence diagrams are a different story. Currently I only support canvas
diagrams where everything is layouted by coordinates. Sequence diagrams
need a dynamic layout engine which is much more complex.

Regards, Jochen

I wasn't aware of this, thanks for the tip. This will make my life
easier as so far i used the desktop snapshot approach...

May I ask what do you mean by "numbered" relations?

Another missing feature is the ability to add self-relation in class
diagrams (like the parent property of the QObject class)

For state diagram, it would be very nice to have something that follows
the specificities of the Qt State machine framework and can export to
SCXML. Support for code generation could be added later then.

Really? You could maybe use a simpler approach where the user can place
lifeline freely on the canvas. A bit like "Gnomw Dia" does.

Mixed it up. I want to implement auto-numbering for relations in
sequence diagrams not state charts.

diagrams (like the parent property of the QObject class)

One of the hidden features - I need to write some user documentation :)

Self-Relation is currently limited to associations between classes (I
should allow self-dependencies for activity diagrams but that will be
part of the customizable relations feature). Start a new assoziation,
press "Shift" to create a new intermediate-point while dragging the
assoziation. Create another intermediate-point and drop the assoziation
at the same class.

BTW, you can always add more points by Shift + Left-Click over a
relation and deleting a point by pressing Ctrl + Left-Click over a
point.

If you simply drag an assoziation and drop it over the same class you
will not get a self-assoziation intentionally.

Please remember that this is an open source tool so you are welcome to
implement some features :)

lifeline freely on the canvas. A bit like "Gnomw Dia" does.

At least one need some good layout helpers to insert and remove
relations in sequence diagrams and move other relations up and down as
needed.

I will start implementing life-lines for canvas diagrams which also help
on activity diagrams.
