What are all the possible settings attributes in TinyMCE's addButton() function?

Question

The documentation is not very clear on this.

name - String - Button name to add.

settings - Object - Settings object with title, cmd etc

Answer 1

Having had the same issue trying to find the addButton docs in V4 I found the link, just in case anybody needs it.

tinymce.ui.Button

Hope it helps someone!
