Hello together,
I am really new in GMF/EMF and I have the following problem:
I am designing an Model editor and want to limit some user actions.
In the Properties view an diagram element has certain properties.
Now I want that the user is not able to change certain properties in this view, but the property has to stay and should not be deleted.
Is there a possibility to hide or disable the combobox/text input or to make a field readonly?

I would be really happy if you could help me.
Thanks

Hi Hans,

this is an EMF related problem. Go to the property in you .genmodel and set its "Property Type" to read only.

Hi Ralph,
thanks for your quick answer Smile
I have found this property and changed it to readonly.
But how do I propagate it to the model editor. I'm using Eugenia to generate the code.
Do you know which steps I have to do, to see the result in the editor finally?

edit:
I want to emphasize that the property should be not settable in the view of the user. I have found that problem in another forum:
eclipsezone.com/eclipse/forums/t116005.html
But there is no solution mentioned.

Hi

the GMF Editor uses the generated Edit code. All you need to do is to generate Edit code after setting the property.
