A string property is very easy for the component user at runtime. A single line of code allows to setup all the subcomponents. And this ease saving/loading the configuration for the application.

As I said before creating/destroying objects on the fly depending on
what the user types in a string property sounds bad in my ears.


Properties assigned thru the OI are not set for each character typed by the user, but at the end of the input. The setter is called once. Having a component reactying to user input thru the OI is what's makes Delphi being what it is. I don't see any problem creating/destroying objects during this process. We are at design time and the component will almost do nothing.

Let's say you want two listeners /192.168.1.1:80/192.168.1.1:443
one SSL and one plain text. Then you have to set SslEnable
property at run time.

Maybe not. Look at TStatusBar, you can add panels and set properties
for each of them individually. This is the kind of thing we need.

Sure it is possible with TCollection and TCollectionItem.
Now we come closer and closer to my first multi-listen server
I wrote 2 years ago <g>. with TCollection however a new string
property "MultiListenAddrPort" was superfluous as well since all
properties can the be set with OI or at run time.


I also wonder when the instances specified by property
"MultiListenAddrPort" will be created?

To be able to have the behaviour I described above, the instances
must be created/destroyed on the fly when MultiListenAddrPort is
assigned a value. We should do just a the panels in TStatusBar: have
a design time user interface (property editor for
MultiListenAddrPort) allowing the user to create each instance and
assign individual addr and port values.

As I said before creating/destroying objects on the fly depending on

I think you should give that a trial yourself, I cannot see what you
want to achieve exactly. Would your design have a single client list
or is it required to iterate over multiple different client lists?
