Hi,
In Delphi TListView is property OwnerData but I can't find comparable
property in Lazarus TListView. I have own data in TList records and I
want show them on TListView. I found VirutalThree but on my latest
snapshot lazarus version I can't install it. I have Error: Identifier
not found "LM_COPYTOCLIP". I remember at some time I install this
component without errors.

In virtualtrees.pas change:

  LM_COPYTOCLIPBOARD to LM_COPY
  LM_PASTEFROMCLIPBOARD to LM_PASTE ...and
  LM_CUTTOCLIPBOARD to LM_CUT

...seems like lmessages.pas changed.

Wow, how old are those sources  ?.
I remember these messages existed, but I cannot find them in the svn
history, so it seems from before that.

Hi,

Sorry for the refresh thread after such a long time, but it is
probably better than creating a new one. I'm curious how it looks now
the case with OwnerData? I found this topic:
http://www.mail-
archive.com/lazarus@lists.lazarus.freepascal.org/msg04117.html
It seems that this option was before. In sources, TListView.OwnerData
property is commented (visible only in protected TCustomListView
section). Why was it disabled? Currently I am using VirtualTreeView
but I do not need 99% of its options. The ideal solution for me is
TListView with OwnerData

Regards

This thread is old, OwnerData is implemented in the meantime for all
widgetsets.
