Getting data from a web page.

jenya7

A weather site suppose to return a JSON data.

void Weather::Get(QUrl url)
{
    QNetworkReply *reply = manager->get(QNetworkRequest(url));
    reply->  ///error: member access into incomplete type 'QNetworkReply'
}

First - I get the error.
Second - what method should I use to retrieve the data?

Your IDE knows a QNetworkReply class exists but not its full definition. You need to

include <QNetworkReply>

to address this.

You need to connect() the reply object signals (readyRead(), finished(), errorOccurred()) to slot(s) in to be notified when data is received. Then you can act on it.

This example has most of the necessary components

Thank you. Works good.

access into incomplete type 'QNetworkReply'

For the record: any time you get an incomplete type '...' message it means you have not included the required header file.
