I try to use a `gui_hooks` named `editor_did_init_left_buttons`. The code for the addon below will be triggered whenever we click the Add new card button.

```auto
from aqt import gui_hooks
from aqt.utils import showWarning

def button(btn, editor):
    showWarning(str(btn))
    showWarning(str(editor))

gui_hooks.editor_did_init_buttons.append(button)

```

The problem is, when I try to print out the content of the first parameter `btn`, all I got is an empty list.  
I search through the code to figure out where does the hook got triggered and I saw it’s in `aqt.editor`.

In the screenshot above, we can see the first argument that is passed to the hook is `lefttopbtns`.

But why the addon I wrote is returning an empty list?

It seems the editor code in your screenshot is outdated. You can see here that `lefttopbtns` is an empty list now: [anki/editor.py at c9bd39c6a212dc5f4a2484da4a0690225bd6d923 · ankitects/anki · GitHub](https://github.com/ankitects/anki/blob/c9bd39c6a212dc5f4a2484da4a0690225bd6d923/qt/aqt/editor.py#L136)

@abdo thanks for the insight.

Just saw the anki package in my machine is **2.3.7**.

I tried to upgrade it to **2.1.49** but I keep getting the error saying requirement not satisfied.

I would suggest trying with Python 3.9, as 3.10 is not fully supported yet.
