changed it.

not sure exactly what you're trying to do, though. There needs to be something that knows the id to use, but you dont show where that is in your code

[Ali Reza]

how to implement with QSignalMapper ?? (if possible)

[amleto]

Why do you want

void LookUpResult(QHostInfo hi , int id)

when id = hi.lookupId()?*

*I believe this is true but I'm not certain.

i want to implement a multi stream HTTP proxy that accept many connections from the browser.
my proxy must look up IP address of the host that specified by each TCP stream (for each http request from browser)
thus i must look up the ip for each stream concurrently
i used QHostInfo ( method LookUpHost() ).
now i want connect the result of this function to my customized slot:

void LookUpResult(QHostInfo @hi , int id)

void LookUpResult(QHostInfo @hi , int id)

To copy to clipboard, switch view to plain text mode 

how ???

thanks

[amleto]

well, you were given the id earlier when you called lookupHost. so save 'id', and when you receive HostInfo you will be ready to call that slot.

[Ali Reza]

please explain to me by coding. i do not understand your mean.
thanks

[amleto]

tell me, what is the difference between

hostinfo.lookupId() and your 'int id' in void LookUpResult(QHostInfo @hi , int id)??

I say there is no difference!

Therefore you don't need

void LookUpResult(QHostInfo @hi , int id)

void LookUpResult(QHostInfo @hi , int id)

To copy to clipboard, switch view to plain text mode 

because you can use

void LookUpResult(QHostInfo hi)
{
  int id = hi.lookupId();
  // ...
}

void LookUpResult(QHostInfo hi)
{
  int id = hi.lookupId();
  // ...
}

To copy to clipboard, switch view to plain text mode
