Managing multiple canvases in a drawing application

Hello everyone,

I am currently developing a drawing application and I want to add a retouching feature. This feature will allow the user to retrieve a previously created drawing and modify it.

To do this, I need to know how to manage multiple canvases in my application. The goal is to be able to display a specific drawing at any time, and to be able to modify it, save it, or create a new drawing.

Why would you need multiple canvases for that? Couldn’t you just load a drawing in the single canvas?

Hello, This will sound strange, but the user will be able to create a “preset” and for each preset there are 8 drawings, that the user can customize and access later. To answer to your question, I have no idea if I can make this work with just one canvas or if I need multiple canvases, that’s my question.

thank you
