[SOLVED]QList and QTcpSocket*
-
Hi, today I'm trying to write simple multithreaded client/server program, which will save connected client's sockets to QList and then send them automatically some messages. I've done something like this:
global_objects.h
[code]#ifndef GLOBAL_OBJECTS_H
#define GLOBAL_OBJECTS_H
#include <QList>
#include <QTcpSocket>QList <QTcpSocket*> Clients;
#endif // GLOBAL_OBJECTS_H[/code]
server.cpp
[code]void Server::incomingConnection(int handle)
{
foreach(QTcpSocket pSocket, Clients) //can't convert from const int to QTcpSocket
{
qDebug() << pSocket;
}mThread *thread = new mThread(handle); thread->run();}[/code]
I'm always getting this error. When I tried for loop, like this:
[code]for(int i = 0; i < Clients.size(); i++) {
Clients.at(i)->socketDescriptor(); //error, -> must point union class or whatever.
}[/code]I don't get it, honestly. Somebody explain me please!

Try using this code:
@
for(int i = 0; i < Clients.size(); i++)
{
(Clients[i])->socketDescriptor();
}
@You should post the whole error message because it's difficult to help you with this information.
And another thing: Some compilers don't like variables in loop definitions like this:
@
for(int i; ...
@You should declare it outside the loop to keep it portable.
On the other hand - this code is possible:
@
for(...)
{
int i;
...
}
