[Gambas-user] Gambas WebPage

[Sebastian Kulesz]

I really like this idea, it makes an application really versatile.
What I think is that before starting to code it you must define some
things.

First, the security implications. Will real webpages be able to use
that syntax?. A nice feature would be a whitelist of allowed pages
that can be executed within a form, maybe with the include tag.

Second, and most important.  How would you manage to call each event
of a form input object, like a textbox? How could someone use the
value of a textbox, for example? What happens if two form objects have
the same "name" attribute? When an input button is pressed, the user
is normally redirected to the "action" webpage, will you override this
to execute an event and let the user choose?

Third, about the links. A nice syntax would be
gambas://FormName/Method/Param1/Param2/...

That's all I could think of. Thanks for all the work!!
