Hello,
I sure hope there is an easy way out of this one.....
I am useing Win32lib by David Cuny with the Treeview/Listview extensions =
by Matt Lewis.
How can I return the [ ID's ] of the Parent and Grand Parent of a child =
or, if the parent is selected how would I get the Grand Parent's ID.
I'm not sure Grand Parent is appropriate terminology but should give you =
a better understanding of the nesting im trying to return..
I currently have twenty or so line to achieve what I'm after but, it's =
much too redundant. --- Help

This is another thing that hasn't really been wrapped, but by adding:
global function getParent( integer id )
return tv_parent[ id ]
end function
to win32lib, you can get the id of a parent. If the return is zero, then
the item has no parent.

Hello,
I inserted the code below and no matter what TV,
deep in a nest or not has always returned 41) as the
parent_id
This is how i tried the code:
index = getTVIndex( TV ) -- this is the current (selected) TV
parent = getParent( index ) -- this should have been the parent of index
am I right? Instead 41 kept comeing up. So, I experimented some and found
that
global function getParent( integer id )
return tvitem_parent[ id ]
end function
does work...... Thanks Matt for putting me in the right direction.
