Hi,
I understand how to implement an IPropertySource for a complex type such
as Point or Dim, but I am stuck on how to do this for an array. Actually a
Hashtable<String,String>. If someone could give me a hint to help my
simple mind grasp this concept, I would greatly appreciate it.
thanks,
B

Wrap the table in another propertysource object. So, create a descriptor
for the hashtable, but that descriptor doesn't need to allow editing or
provide a cell editor. The user will expand the source in the
propertysheet.
Then, in your propertysource implementation, implement getDescriptors() to
just return objects wrapping all of the keys in the table. getValue will
lookup the values in the table.
The propertysheet will call setPropertyValue() bottom-up. You can safely
ignore the setting of the hashtable back into the original source of the
table, but you do need to make sure you fire notification.
Finally, you probably could use a celleditor on the table itself to popup a
dialog which allows the creation of a new key+value pair.
