Hi Graeme
The point is that I havent till now developed any code using 3 tier
approach. Even during my Delphi days. I remember having used 'Raize
Business' components of Ray Canopa during my Delphi 2 days. It had a
Business Table compo that maps to TTable.
Is anybody using actual object model in Lazarus ? I mean, classes for
say 'Purchase Orders' - which will have the modules for persistance like
TQuery /TTable ,defined inside the PO class?
I hear that biggest issue is to map object model to relational model.
Which tool is the best to be used with lazarus/fpc?
regards
Nataraj

Hi Nataraj,
Unfortunately I don't use the tiOPF GUI controls. I tend to stick with
the standard controls and use the Model-GUI-Mediator pattern to make
them object-aware. See the Demos/GenericMediatingViews directory for
demos.
To get back to your problem. Boguslaw Brandys converted quite a few
of the tiOPF GUI controls to Lazarus. Not sure if he did
tiVirtualTrees though - so that could be the problem. If you want to
do the conversion, please go ahead and I will submit the patch.
As a side note: Most of tiOPF GUI controls are composite controls. By
that I mean it is a few standard controls rolled into one and made
object-aware. Unfortunately I cannot comment on the tiVirtualTrees
because I don't even know the standard VirtualTree component. :-)
Sorry I can't be of more help.
Regards,

Hi
I am getting about 50 compile errors starting with the following when
compiling tiOPFGUIDsgn.lpk :-
/root/lazarus/tiOPF2/Source/GUI/tiVirtualTrees.pas(145,20) Error:

what could be wrong?
