There is an easier way for hiding properties: Just open the genmodel
(the EMF generation file), navigate to the property in question, expand
the 'Edit' group and set 'Property Type' to 'none'.

Hello Tobias,
Yes ,this is a easy way.but these common attributes are only shown under
the super class Object and are not shown under sub classes .how to set
'Property type ' to specific attributes under certain sub class?
e.g.super class has attribute Type,but in sub class Data,I don't want Type
be shown.But in the .genmodel,Type is not shown under Data,how can I set
'Property type' to Data?
Regards
ye

Hello all -
I think that you nearly solved this yourself in the initial message... but
try this solution, I hope it works for you...
1.Create a utility method somewhere like this -
public boolean removeDescriptor(Object object, List descriptors,
EAttribute attribute)
{
Assert.isNotNull(object);
Assert.isNotNull(descriptors);
Assert.isNotNull(attribute);
ItemPropertyDescriptor descriptor = null;
for (Iterator iterator = descriptors.iterator(); iterator.hasNext();)
{
ItemPropertyDescriptor tempDescriptor = (ItemPropertyDescriptor)
iterator
.next();
if (tempDescriptor.getFeature(object) == attribute)
{
descriptor = tempDescriptor;
break;
}
}
if (descriptor != null)
{
descriptors.remove(descriptor);
return true;
}
return false;
}
2. Use the utilty method - passing in the object, the current list of
descriptors and the EAttribute you want to remove...
eg.
/**
* This returns the property descriptors for the adapted class.
* <!-- begin-user-doc -->
* <!-- end-user-doc -->
* @generated NOT
*/
public List getPropertyDescriptors(Object object)
{
if (itemPropertyDescriptors == null)
{
List descriptors = super.getPropertyDescriptors(object);
// Remove the type property -
MyItemProviderUtils
.getInstance()
.removeDescriptor(
object,
descriptors,
ModelPackage.Literals.COBJECT_TYPE);
MyItemProviderUtils
.getInstance()
.removeDescriptor(
object,
descriptors,
ModelPackage.Literals.COBJECT_SOMEOTHERTYPE);
addBlahBlahBlahPropertyDescriptor(object);
}
return itemPropertyDescriptors;
}
That should allow you to selectively remove properties from the property
sheet based upon there EAttribute...
Hope that helps
Kristian.
