## Detailed Description

MenuBar consists of drop-down menus, and is normally located at the top edge of the window.

      ApplicationWindow {
          id: window
          width: 320
          height: 260
          visible: true

          menuBar: MenuBar {
              Menu {
                  title: qsTr("&File")
                  Action { text: qsTr("&New...") }
                  Action { text: qsTr("&Open...") }
                  Action { text: qsTr("&Save") }
                  Action { text: qsTr("Save &As...") }
                  MenuSeparator { }
                  Action { text: qsTr("&Quit") }
              }
              Menu {
                  title: qsTr("&Edit")
                  Action { text: qsTr("Cu&t") }
                  Action { text: qsTr("&Copy") }
                  Action { text: qsTr("&Paste") }
              }
              Menu {
                  title: qsTr("&Help")
                  Action { text: qsTr("&About") }
              }
          }
      }

Typically, menus are statically declared as children of the menu bar, but MenuBar also provides API to add, insert, remove, and take menus dynamically. The menus in a menu bar can be accessed using menuAt().
