Lambda function in QT

dhu0504

I am having one member function in the class.

In the same class i am using the below code to interact the aws.

client.connect(&client, &QAwsIoTClient::messageReceived,
[&value](const QString &topicName, const QByteArray &message){
//need to call member function
});

Now i want to call the member function in the above code.

It will be very helpful any one give some solution for this

Hi @dhu0504 said in Lambda function in QT:

client.connect(&client, &QAwsIoTClient::messageReceived,
[&value](const QString &topicName, const QByteArray &message){
//need to call member function
});

You need to capture this to be able to call member functions:

client.connect(&client, &QAwsIoTClient::messageReceived,
               [this, &value](const QString &topicName, 
                              const QByteArray &message) {
   //need to call member function
});

After that it should work nicely.
