Calling copy function when I double clicking on objects?

[Le phan Anh <phanl csse monash edu au>]

Hi all,

I am creating a new object in Dia. It seems that when users double 
clicks on the object, a copy is created and any changes of properties 
applied on the copy. Hmm, that's a little hard for me to do things.

Say I am creating an object O which has a attributes A( A is a list of 
char* by the way), and I dont want to have that displayed as normal 
properties. Rather than that, I will internally update A. The thing is 
how can I copy back from the created copy to the original when user 
click applied?

Anyone have been acrossed this problem before?

Thanks
