The tiOPF has the observer pattern implemented, so you can easily us it for whatever you need. > Is there a way to notify GUI component like List, Edit or TreeView by > tiObject? You can code your own, or simply use the Model-GUI-Mediator (MGM) already implemented in tiOPF v2 (I don't use v3 so can't comment). Notification in both directions get handled for your then. Take a look at Demo 21 in the VCL, LCL or fpGUI folders for a full example of how MGM is used with various standard gui components. MGM supports 3 gui toolkits. If you use MGM, you don't need DB-aware or tiOPF-custom components. Just used stock components like TEdit, TComboBox, TMemo etc.. To find out more about MGM, here is an article I wrote about it. http://opensoft.homeip.net:8080/articles/model-gui-mediator.pdf Regards, - Graeme - ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
