row editable and row not editable

[Akbar <tuxer myrealbox com>]

Hi,

I have treestore. I have two column. Number and String. So the treestore
would be like this:
No    String
|>1.    Stupid
   1.    Bo
   2.    Bee
   3.    Je
|>2.    Idiot
   1.    Dog
   2.    Yo
|>3.    Dumb
   1.    Dub
   2.    Sup
   3.    Mo
   4.    Go

I made the String column editable by:
m_TreeView->append_column_editable("String",
m_TreeView->m_Columns.m_col_string);

Ok, I want to make the children node are not editable, but the parent
editable. How? Right now all node are editable.

Thank you.
