Dynamically add Menu in MenuBar of ApplicationWindow in QML - qt

Question

I'm trying to create an application that is extensible with plugins. Now the plugins should be able to add a Menu dynamically in the MenuBar.
From documentation I can find a MenuBar that is provided by QtLabsPlatform. This has a method addMenu. But Windows was not in the list of supported platforms. So I cannot benefit from it.
I tried the placeholder technique suggested in Error adding a Menu in QML, but this does not work with QtQuick.Controls 2.13

Answer 1

In the #timday answer in the question you indicate indicates the answer but does not show an example:
...
Dynamic creation of Menus is a little harder; see Qt.createQmlObject
or Qt.createComponent docs. (It may be simpler to just declare all the
ones you need in your code, but with their visible property wired to
whatever logic is appropriate). ...
(emphasis mine)
So my answer is just to show you how to do it although I think you want to add MenuItem to a Menu dynamically, instead of a Menu to a MenuBar:
import QtQuick 2.13
import QtQuick.Controls 2.13
ApplicationWindow {
id: root
width: 640
height: 480
visible: true
menuBar: MenuBar {
Menu {
id: plugins_menu
title: qsTr("&Plugins")
}
}
function onTriggered(item){
console.log(item.text)
}
Component.onCompleted:{
var plugin_names = ["plugin1", "plugin2", "plugin3"]
for(var i in plugin_names){
var item = Qt.createQmlObject('import QtQuick 2.13; import QtQuick.Controls 2.13; MenuItem {}',
plugins_menu)
item.text = plugin_names[i]
plugins_menu.addItem(item)
var f = function(it){
it.triggered.connect(function (){ root.onTriggered(it)
})}
f(item)
}
}
}
