\brief A native menubar.
The MenuBar type provides a QML API for native platform menubars.
\image {qtlabsplatform-menubar.png} {A native menubar}
A menubar consists of a list of drop-down menus.
\code
MenuBar {
id: menuBar
Menu {
id: fileMenu
title: qsTr("File")
// ...
}
Menu {
id: editMenu
title: qsTr("&Edit")
// ...
}
Menu {
id: viewMenu
title: qsTr("&View")
// ...
}
Menu {
id: helpMenu
title: qsTr("&Help")
// ...
}
}
\endcode
MenuBar is currently available on the following platforms:
\list
\li macOS
\li Android
\li Linux (only available on desktop environments that provide a global D-Bus menu bar)
\li Windows
\endlist
