Qt not executing after connecting with server

azhagan2

I am using Qt for a client GUI application. For that, I am cross-compiling my GUI to a server in a RfSoC board. During execution, after connecting the client to the server, my GUI stops/strikes.

I printed debug messages using qDebug(). I concluded that, after connecting to the server, it still.

But, when I connected to the same server in a local system, it connected and made use of work.

What will be the issue ?, with my Qt,

Hi,

What are you using to connect to your server ?
Are you sure the connection is successful ?
Are you using any blocking loop ?

@SGaist Hello, Thanks for responding. I am using TCP to connect the socket. Yes, the connection is made successfully, and I printed a message after the connection has made.

Yes, I think I am using a blocking loop, like,

connect(mysocket, SIGNAL(readyRead()), this, SLOT(readyRead()));
detailLabel = new QLabel(this);
detailLabel->setWordWrap(true);

Is this the thing, which is blocking my code to execute ?

@azhagan2
This is not a loop, and does not block. You are looking for something which loops, like some while (....) { ... }, that does not allow the Qt main event loop to run till it finishes.

@JonB No, I am not using any loop in the code

@azhagan2 Then nobody can tell from the detail you have given so far, produce a minimal reproducible example.
