Eventloop and exec()

[MokJ]

Whats an eventloop , and how exec() works?
I have read the documentation of qt but I'm really looking for a bit clearer explanation.
whats the difference between
QThread *thread=new QThread(this);
and
QThread *thread=new QThread();

QTcpSocket * socket=new QTcpSocket(this);
and
QTcpSocket * socket=new QTcpSocket();

how this makes difference?

Hi,

The this parameter that you give makes the object created a child of whatever QObject based class this is.

Did you already read the Threads and QObjects chapter of Qt's documentation ?

@SGaist thanks , and yes I have.
But whats confusing me is , when I'm creating an object of QTcpSocket and and I'm using the instance of a worker object instead of this does that mean that the particular QTcpSocket is the child of the worker object ?

worker *work=new worker();
QTcpScoket socket=new QTcpSocket(work);
work->moveToThread(thread);

and whats QEventLoop?

@MokJ said in Eventloop and exec():

QTcpScoket socket=new QTcpSocket(work);

would indeed make the socket owned by the worker.

QEventLoop, as the name suggest, represent a loop that is processing events. Events can be, for example, mouse events, windows showing and hiding, etc.
