Thank you for @Dunhou answer. It was ultimately completed in JSON format

Hi @Neekoe,

That's great to hear you've managed to solve the issue!

For your future postings please note that according to our Support Procedures:

We cannot debug your code for you and instead provide answers to specific problems.

This effectively means that you're welcome to ask your questions and attach the code snippet that demonstrates your question or issue you're struggling with. However, we cannot debug your entire codebase, so you have to isolate your specific question and the corresponding part of code yourself before asking the question.

Cheers,
Ilia

Thanks @Neekoe to have shared your solution and thanks @Dunhou for helping.
When you pass LV_TREE the Draw method is not called to have it called you need to pass either LV_USERTREE or LV_USER.

Cheers,
Maxime.
