How to spawn buttons inside a GridContainer depending on the number of folders and give names to the buttons.

Question

So i have some sort of "Deck Selection" screen for a card game where you can just put a folder full of .pngs inside res://cards/ and i want those individual folders to appear as "tickable/toggleable" buttons so the user can choose to include every one of them to the output.

How do i expand upon this ?

var DecksList = Array()

func _ready():
    var AddButton = Button.new()
    for n in DecksList:
        add_child(AddButton)

this currently only adds 1 button without a name and not several buttons.
i hope to make it add X amount of buttons where X is the number of stuff in the DecksList, and i want it to name the buttons it adds in order like DecksList[0] and then DecksList[1] and so on automatically.

Hmm surprising this does not throw an error because you continually add the same button.

Correction

func _ready():
    for n in DecksList.size():
        var AddButton = Button.new()
        add_child(AddButton)
        AddButton.set_name("DecksList[%s]" % [n])
        AddButton.set_text("DecksList[%s]" % [n])

Is there a way to edit the style of these generated buttons.

The buttons are literally named DecksList[0], DecksList[1]... etc, can i give the respective folders name to these.

also this will be much to ask but can i get button signal outputs from them so i can assign the signals to... you know whether or not that folder is going to be included in the total array of Cards

Yeah there is you can set the style you want then save it or set it up in code

var style = StyleBoxFlat.new()
style.bg_color = Color.red
AddButton.set('custom_styles/normal', style)

is DeckList a list of Folder Paths? if so

AddButton.set_name(DecksList[n].get_slice("/", 2))

to set up signals are as follows

func _on_pressed(button):
    print(button.name)

func _ready():
    for n in DecksList.size():
        var AddButton = Button.new()
        add_child(AddButton)
        AddButton.connect("pressed", self, "_on_pressed", [AddButton])

this is the DecksList, i want the buttons to be named as the subdirectory folders like
Button1 = Base Cards
Button2 = Booster Pack 1
etc...

This is the output i get when i "print(DecksList)"

var DecksList = [res://cards/., res://cards/.., res://cards/Base Cards, res://cards/Booster Pack 1, res://cards/Booster Pack 2, res://cards/Max Basic Pack, res://cards/Max Booster Pack 1, res://cards/Max Booster Pack 2, res://cards/Max Magic, res://cards/Optimized Cards (Hard)]

also i have noticed a problem just right now that i have 2 "res://cards/." in the array.

i'm using this code to generate it and i assume those 2 will interfere with what i'm trying to do, so how do i remove those, i don't even know why they are generated.

var numCards = 0
var dir = Directory.new()
var DecksList = Array()
var CardsPath = "res://cards/"

func _ready():
    if dir.open(CardsPath) == OK:
        dir.list_dir_begin()
        var file_name = dir.get_next()
        while (file_name != ""):
            if file_name.ends_with(".import"):
                pass
            else:
                DecksList.push_back((CardsPath)+file_name)
            if dir.current_is_dir():
                numCards += 1
            file_name = dir.get_next()
            print(DecksList)

To get the base folder of any path use the following

get_base_dir().get_file()

so the name will be

AddButton.set_name("%s" % DecksList[n].get_base_dir().get_file())

you can fix the double "res://cards" by using

dir.list_dir_begin(true)

and

dir.list_dir_begin(true, true)

#to avoid having to use this line
if file_name.ends_with(".import"):

You've been an unbelievable help,

dir.list_dir_begin(true)

until i saw this, i was using

DecksList.remove(0)
DecksList.remove(0)

to fix the problem :D
