Re: [gef-dev] showing properties in the property view

This is a common problem.  You
just need a metamodel similar to BeanDescriptors in the bean specification,
perhaps using EMF with metamodel annotations for indicating things like
CellEditors, etc. Google introspection and metamodels.

Subject	Re: [gef-dev] showing properties in the property view

Hi,

in my oppinion ... this is quite difficult. The problem is that you need
to 
know how each property will be represented by a certain PropertyDescriptor.
If all properties will be represented by a TextPropertyDescriptor it would
be 
easier to solve your problem. But thats not the fact now.
Try making a getProperty() call enumerate over this collection and generate
a 
TextPropertyDescriptor for each property contained. Save your generated
PropertyDescriptors in a Hashtable with unique identifiers.
Implement the methods your class inherits from IPropertySource. The parameter
"id" each method gets must now be mapped to the corresponding
property.
Assuming all methods from IPropertySource are implemented now and your
editor-class is prepared for using the propertysheet, everything will work.

Please tell me if this works ...

regards

Andreas
