Read-Only Graphiti Diagrams [message #677170]

Can anyone suggest a strategy for displaying a read-only Graphiti diagram? The use case would allow users to inspect a diagram and select elements, but not create, move, delete, or edit elements. Selection is required to allow access to element property sheets.

You can create a read-only version of your Graphiti diagram editor by providing an additional feature provider (FP). If this FP does not provide any modifying features, the diagram could not be changed. It is also possible to switch between editing an RO mode. Some intersting sources for you could be the following ones:
SketchViewerModeToolBehavior, ConfigurableFeatureProviderWrapper

See http://www.eclipse.org/forums/index.php/mv/msg/207099/663075/#msg_663075.

Redefining all the named features effectively makes the diagram read only. We did this because we generate the layout automatically and do not want the user to be able to change it.

Thank you both.

I extended my ToolBehaviorProvider implemented IFeatureCheckerHolder and supplied a new FeatureCheckerAdapter(false). Then wrapped my IFeatureProvider in a ConfigurableFeatureProviderWrapper and Viola! It might sound scary, but the whole thing was pretty trivial after I understood how the example Christian cited worked.

Jos, I can see why your solution is more appropriate for your situation. I need both a editable and a read-only version of the editor, so the ability to just disable the whole thing when needed worked out best for me.

Thanks again.

Perhaps we should take a read-only chapter into our documentation... Smile
