Thank you,
But almost I am really confused, that example is for Delphi, the
TTreeView implementation of Lazarus is a little bit different, the
number of parameters and declaration of CustomSort are different.
I just try with the example of the webpage and I get a compiler error:
Error: Incompatible type for arg no. 1: Got "<address of
function(TTreeNode, TTreeNode, LongInt):LongInt;StdCall>", expected
"<procedure variable type of function(TTreeNode, TTreeNode):LongInt of
object;Register>"
Thank you for your help.

Subject: [lazarus] Example how to sort a TTreeView
First of all happy new year,
Can anybody show me how to sort a TTreeview? I am trying with the
Customsort method but I don´t know how to call the right parameters.
|TTreeView.CustomSort(SortProc: TTreeNodeCompare): Boolean;|
<http://www.lazarus.freepascal.org/lcl_doc/TCustomTreeView.html#link2668>
Could you show me a little example of how to declare the SortProc
Variable of type TTreeNodeCompare?
Thank you for your help,
Alex
