Qt Creator plugin: how to insert foreign widgets from my plugin into QtQuick Designer

[mut]

Hello;

I'm building a plugin for Qt Quick Designer.

I want to know the objects in pluginmanager that belong to Qt Quick Designer in order to access them in my own code?

In particular: how to add items and handle selection for the case of these UI objects:

- Object1: “Library” dropdown list
- Object2: “main.qml” dropdown list
- Object3: “Open Documents” dropdown list

Thanks;

Mut
