CSS Canonical does not work in SysML [message #1700354] Thu, 02 July 2015 07:05 Go to next message

Hi, I've tested the canonical function of CSS with UML and SysML.
Here are my observations:
- UML :
+ canonical = true => all ports (of a certain part in a composite diagram) appears
+ however, right then, I modify canonical = false => the ports will not disappears. That means, once the properties are showed, they can not be unshowed by setting canonica = false

- SysML : canonical does not function in IBD

Could anyone show me how to get this done in SysML?
Thanks for your help.

Thanh Liem.

I've also noticed that, if I register a new DropEditPolicyProvider (with a new DropEditPolicy) via extension org.eclipse.gmf.runtime.diagram.ui.editPolicyProvides in Papyrus, the canonical function with not run even with UML diagrams.

Hi Liem,

Quote:

That's intentional: the synchronization mechanism automatically displays everything (Populates the diagram), but it doesn't need to be active at all time. If the elements are not synchronized, then the mechanism simply does nothing. It doesn't keep track of elements that have been automatically synchronized, vs the ones that have been manually displayed.

Undoing canonical = true works, however.

Regards,
Camille

Hi, Thanh Liem,

The canonical edit policy does not purport to remove views when it is
disabled. It only removes views for elements that should no longer be
shown as child nodes or connected edges because the structure of the
model has changed.

If the SysML IBD has some missing canonical behaviour, then perhaps it
needs to register some canonical strategies to make that work. Please
raise a bug on the SysML component.

Cheers,

Christian

Hi,

The Papyrus mechanism for customization of drag-and-drop on the
diagrams is the "drop strategies" extension point:
org.eclipse.papyrus.infra.gmfdiag.dnd.dropStrategy. By replacing the
Papyrus drop edit policy via the GMF extension point, you have removed
the mechanism that the canonical edit-policy relies on for creation of
new diagram views.

So, try implementing your custom drop behaviour using a drop strategy
instead and see whether that restores the canonical presentation.

HTH,

Christian

Thanks Christian,

The fact that I need to set myDragDropStrategy as a drag&drop default strategy also. So if I don't replace the default DropEditPolicyProvider by a new one, I couldn't achieve this requirement, and each time user drag&drop a component from the lib, Papyrus will display a list of strategy to choose.
And it's redundant action for the end user.

Do you have any idea?

Thanks for your help.

Right, probably best to set your drop strategy as a default to
encourage consistent behaviour for your users.

I know of no definitive means by which you can avoid the drop
strategies contributed by plug-ins. There may be a Preference Page in
which you can selectively disable drop strategies. If there isn't,
there should be one (please raise a bugzilla in this case).

Cheers,

Christian

Thanks Christian, I will try with the Preference Page solution in order to set the default drag&drop strategie.
By the way, if it's not so complicated, could you show me how to set the canonical strategies for SysML?
Thanks and best regards.
Thanh Liem.

Hi, Thanh Liem,

What do you mean by "set the canonical strategies for SysML"? It's up
to the SysML diagrams to define strategies (if required) for canonical
synchronization. This isn't intended for user extensibility.

Cheers,

Christian

Hi Christian,
I just reuse your phrase in the previous reply.
But, may be i misunderstood.
Thanks.

Hi Christian,

When I register a new D&D strategy (disable the registration of the new EditPolicyProviders), the popup menu is like the following :
index.php/fa/22448/0/

There are two dnd strategies in this case:
- the new one I've just created "Drop the component from the Spider Library"
- and "Selection drop action for"

But in fact, "Selection drop action for" is not listed in the Preferences\Papyrus\Drag&Drop. This is a default DnD strategy, which is created "on the fly" in the class DropEditPolicy, which is then instantiated by DropEditPolicyProvider.

That means, evens I deselect all d&d strategies but my own one (cf the figure below), the popup menu is always displayed when user drag&drop a component from model lib.
index.php/fa/22449/0/

Do you have any idea?

Thanks and have a nice day.
PTL.

Hi, PTL,

That is a bug. Would you mind raising it in bugzilla?

https://bugs.eclipse.org/bugs/enter_bug.cgi?form_name=enter_bug&product=Papyrus&version=1.1.0


Thanks!

Christian
