Best technique for this case
-
I need options to solve this problem: I want to support several domains in order to grab a few information on them, for example: CNN, USA Today, NY Times, Fox News and so on.
Imagine that the user has a link to one of the networks listed above, and he puts it in aQLineEditand press the button to submit, I want the application to parse the address and find who can handle that domain. I though of using the plugin system in order to register the handlers for the domains, but I don't know how to determinate who can handle who and call the right one.Is there a way to create handlers for each domain and determine who can handle the domain?
Thank you.

Hi and welcome to devnet,
I think your question is too generic; anyway you could use
QUrlto parse the user input and detect the domain.Are you trying to implement a feed reader?
@mcosta I think that I found what I was looking for, it's the chain of responsibility pattern, the only thing missing is how to return a value in a chain if the handler can handle and return an error if no handler can handle the network. Is this a case for use
QVariant?
