    <p>The easy way to make that is modifing moc preprocessor. </p> <ol> <li>Go to Qt source code to <strong>qtbase/src/tools/moc</strong> e.g. (C:\Qt\Qt5.0.1\5.0.1\Src\qtbase\src\tools\moc)</li> <li>Create a new copy of moc project e.g. moc_modified</li> <li>Open the copy of moc project with QtCreator (moc.pro file)</li> <li>Open preprocessor.cpp file and go to <strong>Symbols Preprocessor::preprocessed(const QByteArray &amp;filename, QIODevice *file)</strong> function</li> <li><p>Search the line:</p> <pre><code>// phase 1: get rid of backslash-newlines input = cleaned(input); // &lt;- insert your code to modify input variable // input is a QByteArray object that contents the source code of .h file than moc is processing // I had created the replaceCustomMacros function, see next line replaceCustomMacros(input); ... </code></pre></li> <li><p>Compile the new source code. The moc executable file is generated to /bin folder (if you use windows look at c:/bin/moc.exe)</p></li> <li><p>Go to Qt bin (C:\Qt\Qt5.0.1\5.0.1\msvc2010\bin) folder and rename moc executable file e.g. moc.exe.bak</p></li> <li><p>Copy new moc executable file to Qt bin folder.</p></li> <li><p>In your current app you need to create a Macro for example:</p> <pre><code>#ifndef Q_MOC_RUN #define DB_FIELD( PROPERTY, COLUMN ) #endif //or in my case #ifndef Q_MOC_RUN #define Q_SERVICE_INFO(method, path, type) #endif </code></pre></li> </ol> <p>Finally I let you my own source code of function replaceCustomMacros:</p> <p>This function convert <strong>Q_SERVICE_INFO(method, path, type)</strong> macro to <strong>Q_CLASSINFO("srv://method", "type:path")</strong></p> <pre><code>void Preprocessor::replaceCustomMacros(QByteArray &amp;source) { QString str(QLatin1String(source.data())); QString param_exp(QLatin1String("([^,\n]+)")); QByteArray expression("Q_SERVICE_INFO\\s*\\("); expression .append(param_exp.toLatin1()) .append(",") .append(param_exp.toLatin1()) .append("(,") .append(param_exp.toLatin1()) .append(")?\\)"); QRegExp *reg_ex = new QRegExp(QLatin1String(expression)); int pos = -1, offset = -1, len = str.length(); while ((offset = reg_ex-&gt;lastIndexIn(str, pos)) != -1) { reg_ex-&gt;cap(1); pos = -(len - offset) - 1; QString capturedString = reg_ex-&gt;capturedTexts().at(0); QString pattern = capturedString; pattern.remove(0, pattern.indexOf(QLatin1String("(")) + 1); pattern.remove(pattern.length() - 1, 1); QStringList params = pattern.split(QLatin1String(",")); QString method = params.at(0).trimmed(); method = method.mid(1, method.length() - 2); QString type; if (params.length() &lt; 3) { type.append(QLatin1String("GET")); } else { type = params.at(2).trimmed(); type = type.mid(1, type.length() - 2); } QString path = params.at(1).trimmed(); path = path.mid(1, path.length() - 2); source.replace(offset, capturedString.length(), QString(QLatin1String("Q_CLASSINFO(\"srv://%1\",\"%2:%3\")")).arg(method, type, path).toLatin1()); } delete reg_ex; } </code></pre> <p>I have not found any specific solution on Internet then I have posted this solution.</p> <p>Good Luck :)</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.
