How do I make a read-only property? [message #144351]

I have a field named x.

I want it to be visible in the Property Sheet only when the designer selects "Show read only properties".

I want to make it a read-only field, so I created a getX, but not a setX.

But when I tell getPropertyDescriptors to add the property, it throws because I have no setX.

PropertyDescriptor doesn't seem to have a setter to specify readOnly. Or did I miss it?

How do I create a readOnly property?

Thanks,
Eli

Hi Eli,

I've just read a white paper about a plugin extended from VE and i find
out sth interesting concerning your question:
You can modify the override file of your Bean and add estructural features.
Inside the label addedEObjects you must set the property
changeable="false".
Further information in this doc:

Bye¡

So far as I can tell, "changeable" is applicable to ULC, not to VE itself. If I'm wrong, please let me know.
Thanks!

You can modify the BeanInfo file of your Bean
eg:
result[num] = new PropertyDescriptor("x", class,getX,null);
