How to find registered qml types from c++ with public api ?

[Kwan]

Hi, im writing system monitor like application, for which user can define its layout. From json property i instantiate qml object and set properties for it. I would like to give my users access to built in qml types (rectangle, item and so on).

1. Is there way to create these qml types from c++ by name?

2. Also is there way to find all registered qml types ? I'm planning to create simple wysiwyg editor, which would create json for users and i would like to show there qml types also. I know there is private api i can use. But i would be glad if it is posible to make only with public api.

Ps: I know i could create qml from given json or make user create qml themselves but i dont want to do that.

not directly.
But for simple tasks you could do something like that:

QQmlComponent component(engine);
component.setData(
"import QtQuick 2.0" "\n"
"Rectangle {" "\n"
"}"
);
QQuickItem *rectItem= qobject_cast<QQuickItem*>(component.create());
QQmlProperty::write(rectItem, "width", QVariant::fromValue<qreal>(100.0));
QQmlProperty::write(rectItem, "height", QVariant::fromValue<qreal>(50.0));

depends what module you do import.
You can parse the .qmltypes files (e.g. <QTDIR>/qml/QtQuick.2/plugins.qmltypes) which expose all types the plugin/module provides.
