    <p>I need to check the Internet Connection If I get Socket Error. I am proceeding like this,</p> <pre><code>void Client::socketError(QAbstractSocket::SocketError socketError) { HttpPost("https://www.google.co.in/"); } void Client::HttpPost(QString URL ) { QNetworkRequest request = QNetworkRequest(); request.setUrl(QUrl(URL)); QNetworkAccessManager *mNetworkAccessManager = new QNetworkAccessManager(this); bool result = connect(mNetworkAccessManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(HttpResponse(QNetworkReply *))); mNetworkAccessManager-&gt;get(request); qDebug() &lt;&lt; "::: Client.cpp Request made to Service :::"; } void Client::HttpResponse(QNetworkReply* reply) { if (reply-&gt;error() == QNetworkReply::NoError) { qDebug() &lt;&lt; "\n Internet Ok **********"; } else { qDebug() &lt;&lt; "\n No Internet **********" &lt;&lt; reply-&gt;errorString(); showDialog("No Inernet"); } } </code></pre> <p>and I am connecting to Signals and Slots like </p> <pre><code>connect(socket, SIGNAL(error(QAbstractSocket::SocketError)), this, SLOT(socketError(QAbstractSocket::SocketError))); </code></pre> <p>But some times I am getting "No Internet Dialog " Even If wi-fi Is Available. Why ?</p> <hr> <p>Method 2:</p> <pre><code>// this method will return true If Net is available false other wise // but even this is return false some times even Wi fi signal is Available bool Client::isNetworkAvailable() { bool isFound = false; QNetworkConfigurationManager netMgr; QList&lt;QNetworkConfiguration&gt; mNetList = netMgr.allConfigurations(QNetworkConfiguration::Active); if (mNetList.count() &gt; 0) { if (netMgr.isOnline()) { isFound = true; } } qDebug() &lt;&lt; "\n ************** isNetworkAvailable:::" &lt;&lt; isFound; return isFound; } </code></pre> <p>Is there a problem in my code?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
