As a part of making gmf editor i want to return a comboboxcelleditor for certain datatypes(enum) in my metamodel

so i have implemented my own property descriptor and returned comboboxcelleditor as a cell editor.

but in the gmf editor when i click on show property view, for that data type it's displaying a uneditable default value(default value given enum datatype.

what do i do if i want to show a comboboxcelleditor for that enum datatype

customized proprty descriptor
below DNTypes is the enum data type declared in the meta model.
if everything works fine it should show type1,type2.. in combobox but it isn't showing up
------------------------------------------------------------ -------------
public CellEditor createPropertyEditor(Composite composite) {
CellEditor result=super.createPropertyEditor(composite);

if (result==null)
return null;

EClassifier eType = ((EStructuralFeature) itemPropertyDescriptor

if (eType instanceof EDataType) {
EDataType eDataType = (EDataType) eType;
if(eDataType.getInstanceClass() == DNTypes.class)
String s[]={"type1","type2","type3","type4"};
ComboBoxCellEditor cbe=new ComboBoxCellEditor(composite.getParent(),s,getEditLabelProvi der);

return cbe;
//return result;



return result;

------------------------------------------------------------ -----------

any pointers how to proceed

Hi Aurelien,

Thanks for the post, it is very helpful. I have succeeded to create my own File Selector in the property sheet. You're the hero!

My solution is here if someone is interested:
