How to add a close button to each tab with TabContainer?

Question

Just like the Google Chrome browser, I would also like to add a button to add a new one at the end of the tabs. I welcome any suggestions.

Answer 1

I used a Tabs control which is simply like a button that doesn't depend on any child,
to align it to the top I put it inside a VboxContainer.
To add new tabs (Contrary to the intuition of adding or duplicating the Tabs control) I using code:

addtab ("tab1")
addtab ("tab2")

And to show the close button on the selected tab:

settabclosedisplaypolicy (CLOSEBUTTONSHOWACTIVEONLY)

I still have to see how to display a custom tab with the + symbol and not show the close button when clicked...
