How do I connect a button pressed signal with code in Godot 4?

[Darkmisc]

TL;DR Summary

I've tried connecting a button pressed signal with nBut.pressed.connect(test.bind()), but it doesn't work.

Hi everyone

I've downloaded a file explorer for Godot 4. It creates a button for every file in the open directory. When you press the button, it fills a prompt with the path to the file.

This is the code for it:

nBut.pressed.connect(open_folder.bind(file_name))func open_folder(folder_name:String):
    if file:
        path = path.get_base_dir()
    path = path + "/" + folder_name
    set_layout()

I'd like to modify the code so that something else happens when you press the button.

I've tried using this code:

nBut.pressed.connect(test.bind())

func test():
    print("test")

The code doesn't give me an error message, but it doesn't print "test" when I press the button. The existing code, however, will run file_open.

I've also tried nBut.pressed.connect("test", self)

nButpressed.connect(self, "test")

and

nBut.pressed.connect("pressed", self, "test")

but none of these work either.

Does anyone know the correct way to do this?

I can't connect the signal in the inspector because I'm not making the buttons manually. I need code to do it because I won't know how many files (and corresponding buttons) there will be in the directory.

Thanks
It won't print when I put print commands into open_folder, although it will print if I put print commands into _ready(). Not sure why that is.

EDIT:

func open_folder(folder_name:String):
    print("A")
    if file:
        print("B")
        path = path.get_base_dir()
    path = path + "/" + folder_name
    set_layout()

Nvm. It works. Problem was that I didn't understand another part of the code.
