问题
It's factible or it uses some compiler technology only available in XE2 ?
I just want to bind (bidirectional) a TEdit.Text property to a object function that returns a string in code (I don't need designer components or expression evaluators)..
Thanks!
回答1:
I guess you could try Delphi sorcery library. It has quite powerful data binding solution which should work in all the modern Delphi versions.
回答2:
No, as far as I can tell, the LiveBindings system was implemented entirely in code with no new language features introduced to support it. Which is a bit of a shame, IMO; it could be a much simpler and overall better system if the language had support for something like property references.
