Hi,

We already have Precondition Service to prevent creating diagram. But how about the post-service after diagram created?

One of use cases, after diagram loaded/ re-loaded, i would like to activate Read-Only mode, which Not allow user drag/drop/delete/edit any elements in the diagram.

Any solution?

Thanks.

Thanh Huy LE.

Hello,

If I understand right, you want Sirius to behave as a viewer instead of
an editor?
In the DiagramDescription, if you describe only describe a "Delete tool"
with no action in its tasks, you will obtain a diagram where to user is
not able to drag/drop/delete/edit any elements in the diagram. However,
he will be able to move them in the diagram.
Is this solution good enough?

Regards,
Steve

Hello Steve,

See my answer as below:

an editor?


=> YES.

In the DiagramDescription, if you describe only describe a "Delete tool"
with no action in its tasks, you will obtain a diagram where to user is
not able to drag/drop/delete/edit any elements in the diagram. However,
he will be able to move them in the diagram.
Is this solution good enough?


=> Moving is not allowed as well.

Another solution is removeEditPolicy of each EditPart, but when any change in the model, the policy is reset, the diagram back to editable mode.

I'm still in stuck.

Hello,

Depending your goal, maybe exporting representation as images is enough?
You can do it programmatically by using the API
DialectUIManager.INSTANCE.export(...).
If your really need to use Sirius as a viewer (well a read-only editor),
you either can implement a ResourceSetListener in post-commit which
rolls-back the transaction or implement a IPermissionAuthority that will
return false to the canEditFeature/Instance methods.

Regards,
Steve
