The database is checked at startup, and created if it does not exist. LocalStorage uses SQLite, which is a self-contained, serverless, public-domain database. Opening a connection to the database is handled at the beginning of each function that manipulates or retrieves data.</p> <p>Files:</p> <ul> <li><a href="qtquick-localstorage-localstorage-pro.html">localstorage/localstorage.pro</a></li> <li><a href="qtquick-localstorage-localstorage-database-js.html">localstorage/localstorage/Database.js</a></li> <li><a href="qtquick-localstorage-localstorage-header-qml.html">localstorage/localstorage/Header.qml</a></li> <li><a href="qtquick-localstorage-localstorage-mybutton-qml.html">localstorage/localstorage/MyButton.qml</a></li> <li><a href="qtquick-localstorage-localstorage-mydelegate-qml.html">localstorage/localstorage/MyDelegate.qml</a></li> <li><a href="qtquick-localstorage-localstorage-mymodel-qml.html">localstorage/localstorage/MyModel.qml</a></li> <li><a href="qtquick-localstorage-localstorage-localstorage-pro.html">localstorage/localstorage/localstorage.pro</a></li> <li><a href="qtquick-localstorage-localstorage-localstorage-qml.html">localstorage/localstorage/localstorage.qml</a></li> <li><a href="qtquick-localstorage-localstorage-localstorage-qrc.html">localstorage/localstorage/localstorage.qrc</a></li> <li><a href="qtquick-localstorage-localstorage-main-cpp.html">localstorage/localstorage/main.cpp</a></li> </ul> </div> <!-- @@@localstorage --> </div> </div> </div> </div> </div> <div class="footer"> <p> <acronym title="Copyright">©</acronym> 2019 The Qt Company Ltd.
