[Gambas-bugtracker] Bug #2929: Generic Events

[<bugtracker@xxxxxxxxxxxxxx>]

http://gambaswiki.org/bugtracker/edit?object=BUG.2929&from=L21haW4-

Fabien BODARD reported a new bug.

Summary
-------

Generic Events

Type             : Request
Priority         : Medium
Gambas version   : Unknown
Product          : Unknown


Description
-----------

I there a way to have something generic on class for Data Structure that allow to know whereas one of the content value is changed or at least try to be changed.

for example :

CLASS MyData
  Property Id as integer Use $id
  Property Name as Integer Use $sName
END CLASS


Private $hData as new MyData as "Data"

Public sub Main()
  $hData.Id = 3  
End

Public sub Data_Change(Name as string)
  Print "Property : " & Name & " modified"
End


This is the Idea... Or Maybe a generic thing in the Child Class such as a _PropertyRead(Name) Event called by the interpreter
