Hi Helmut,
Elan seems to have answered your first question that pertains to protecting
attributes in objects.
I am not sure that I fully understand what you are asking in your second
question:
...
> > 2) how can I get an event, when an object variable is changed?
...
Maybe an example will help. Here is an object with attributes and functions
taken from:
http://www.rebol.com/rebolsteps.html
account: make object! [
name: "Flintstone"
balance: $100
ss-number: #1234-XX-4321
deposit: func [amount] [balance: balance + amount]
withdraw: func [amount] [balance: balance - amount]
]
Are you asking how to "fire" an event if an attribute, such as 'balance, is
changed? Or are you asking how to get and set the attribute? Or are you
asking something else entirely?
