How to create and save object to put in another qml?

[VVNart]

The app that I'm doing is to select range of items to decorate a "cake" and save it into an image. There are 3 parts that I'm trying to figure out:

1. Create Object - after select items from a list, how to create the object after click the button?

2. Remove Object - sometimes if want to do any changes, I need to remove the object to add new object on it. Is it possible to remove the previous object? This is to prevent from using up the RAM.

3. Save object - After done customize, how am I save all the objects and link to another qml so that I can use it back?

For 1 and 2, read Dynamic Object Management in QML
For 3 ... interesting question. Do you intend to save it as QML or as a binary representation of the composition, which can be later rendered back through your application using QML?

I'm not sure which is the best way. After done customize, I want to maintain object as it is and bring it to the next QML for "screenshot" it as image.

So I would not save it. Just want to maintain it to use for the next QML.

Bring it to the next QML? There is only one object tree in your application, with a root item and all the other being its descendants of various degrees. Your "next QML" is therefore very likely just another branch of the tree, while your customized object is also living somewhere there, it the objects tree.

I see. So is more complicated or it just impossible to be done?

I'll seek another alternative which is all in one QML perhaps? I'm just trying to avoid using a lot of states that using RAM a lot.

Thanks for the advice. Nice to meet you
