    <p>In the following code, I'm having some sort of issue getting my .yaml file parsed using <code>parser.GetNextDocument(doc);</code>. After much gross debugging, I've found that the (main) issue here is that my for loop is not running, due to <code>doc.size() == 0;</code> What am I doing wrong?</p> <pre><code>void BookView::load() { aBook.clear(); QString fileName = QFileDialog::getOpenFileName(this, tr("Load Address Book"), "", tr("Address Book (*.yaml);;All Files (*)")); if(fileName.isEmpty()) { return; } else { try { std::ifstream fin(fileName.toStdString().c_str()); YAML::Parser parser(fin); YAML::Node doc; std::map&lt; std::string, std::string &gt; entry; parser.GetNextDocument(doc); std::cout &lt;&lt; doc.size(); for( YAML::Iterator it = doc.begin(); it != doc.end(); it++ ) { *it &gt;&gt; entry; aBook.push_back(entry); } } catch(YAML::ParserException &amp;e) { std::cout &lt;&lt; "YAML Exception caught: " &lt;&lt; e.what() &lt;&lt; std::endl; } } updateLayout( Navigating ); } </code></pre> <p>The .yaml file being read was generated using yaml-cpp, so I assume it is correctly formed YAML, but just in case, here's the file anyways.</p> <pre><code>^@^@^@\230--- - address: ****************** comment: None. email: andrew(dot)levenson(at)gmail(dot)com name: Andrew Levenson phone: **********^@ </code></pre> <p><strong>Edit:</strong> By request, the emitting code:</p> <pre><code>void BookView::save() { QString fileName = QFileDialog::getSaveFileName(this, tr("Save Address Book"), "", tr("Address Book (*.yaml);;All Files (*)")); if (fileName.isEmpty()) { return; } else { QFile file(fileName); if(!file.open(QIODevice::WriteOnly)) { QMessageBox::information(this, tr("Unable to open file"), file.errorString()); return; } std::vector&lt; std::map&lt; std::string, std::string &gt; &gt;::iterator itr; std::map&lt; std::string, std::string &gt;::iterator mItr; YAML::Emitter yaml; yaml &lt;&lt; YAML::BeginSeq; for( itr = aBook.begin(); itr &lt; aBook.end(); itr++ ) { yaml &lt;&lt; YAML::BeginMap; for( mItr = (*itr).begin(); mItr != (*itr).end(); mItr++ ) { yaml &lt;&lt; YAML::Key &lt;&lt; (*mItr).first &lt;&lt; YAML::Value &lt;&lt; (*mItr).second; } yaml &lt;&lt; YAML::EndMap; } yaml &lt;&lt; YAML::EndSeq; QDataStream out(&amp;file); out.setVersion(QDataStream::Qt_4_5); out &lt;&lt; yaml.c_str(); } } </code></pre>

    1. COWhat's the `^@^@^@\230` that's starting the file? (and the `^@` that's ending it?) If `yaml-cpp` is truly emitting that, can you post your emitting code as well?

    2. COI don't know what that is, so I put up the emitting code. Maybe it has something to do with setting the Qt version?

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.
