How to get all items in an item list ?

Hello,
currently itemList only returns an array of the --->selected items<----

if a list has this selected it returns fine

item 0
item 1
item 2
item 3

the problem is i Cant move an item UP or DOWN, the list doesnt update unless i mouse click the item again,
i dont know how to explain anymore, or even understand what iam saying to explain this...

this thing only gives you values throw a signal and the user has to mouse click on it

itemLlist1.multi_selected.connect(self.itemLlist1_selected); 

var itemListNum: int = 0;
var itemselected: bool = true;

func itemLlist1_selected(index, selected):
	#print(  str(index) + str("  ") + str(selected)   );
	itemListNum = index;
	itemselected = selected;
	PlugTileDrawNode.layerPOS = index;

this way when i move an item UP or DOWN it doesnt update the correct position, like get_selected_items ( ) does...
it only gives you the currect position if you use that signal.

Is there a way to get all items on the list ?
so i can make it work togheter with the get_selected_items ( )

xyz thanks, it seems the problem is another thing

I need to push the value in an array up or down
currently there is only push_back and push_front and this add a value in front or back...
I cant do it by copying the values and change place

this is the array: layers.Lnum

var layers = {
	'Lnum': [ {} ]
}

this is how its being set up:

func _draw():
	
	if ( Engine.is_editor_hint() ):		
	
	for p in range(0, layerMax ):
		for i in layers.Lnum[p]:
			if ( layers.Lnum[p].has(i) ):
				draw_texture( layers.Lnum[p][i], i );

I wanted this layers.Lnum[] to change positions up or down withOut loosing the contents that are on it

[EDIT]

chatGPT says array in godot4 has the 'move' method...

In Godot 4, you can change the positions of values in an array using the move method or by manually swapping elements. Below are examples of both methods.
Using the move Method

The move method is built into the Array class in Godot and allows you to move an element from one position to another within the array.

I have the ItemList on an EditorInspectorPlugin in the right Dock Inspector
And the Array on a costum node the EditorPlugin handles

How iam supossed to do this ?
iam going to have to start over, and then i will find more unsolvable problems, like adding a dictionary to an itemList

xyz

the editor plugIN
loads an instance and the EditorInspectorPlugin and creates a costum node

@tool
extends EditorPlugin

const menuScene = preload("res://menu/menu.tscn");
const tileDrawNode = preload("res://test3/tileDrawNode.gd");
const tileDrawIcon = preload("res://test3/icon.png");

#---------//---inspector---//---------
var tlDrawInspector = preload("res://addons/tiledrawtest2/tileDrawInspector.gd");

func _enter_tree():
	add_custom_type("TileDraw", "Node2D", tileDrawNode, tileDrawIcon );
	dockedScene = menuScene.instantiate();
	add_control_to_container(CONTAINER_CANVAS_EDITOR_SIDE_RIGHT, dockedScene );
	dockedScene.custom_minimum_size = Vector2(10,0);
	
	tlDrawInspector  = tlDrawInspector.new();
	tlDrawInspector.PlugInDockedScene = dockedScene;
	add_inspector_plugin(tlDrawInspector);

var TileDrawNode;

func _handles(object: Object) -> bool:
	#return object is tileDrawNode
	if ( object is tileDrawNode ):
		TileDrawNode = object;
		return true
	return false

the costum node 'tileDrawNode' draws all of this stuff in engine editor screen

@tool
extends Node2D
class_name tileDrawX1;

var layers = {
	'Lnum': [ {} ]
}

		for i in range(0, drawText.get_image().get_size().x,32 ):
			for j in range(0,  drawText.get_image().get_size().y, 32):
				
				mouseGroup.Fnum.append(  { "cords": Vector2(i, j), "img": ImageTexture.create_from_image(drawText.get_image().get_region( Rect2( i, j, 32, 32) ) ) } );


func _draw():

	for p in range(0, layerMax ):
		for i in layers.Lnum[p]:
			if ( layers.Lnum[p].has(i) ):
				draw_texture( layers.Lnum[p][i], i );

and the EditorInspectorPlugin adds a menu to the inspector with the itemList and other things

@tool
extends EditorInspectorPlugin

var itemLlist1;

func _can_handle(object):
	if object is tileDrawX1:
		PlugTileDrawNode = object;
		return true
	return false



func _parse_end(object):
	itemLlist1 = ItemList.new();
	itemLlist1.set_custom_minimum_size(Vector2(100, 90));
	itemLlist1.set( "theme_override_styles/focus",StyleBoxEmpty.new() );
	itemLlist1.select_mode = 1;

	for n in 3:
		itemLlist1.add_item("     layer " + str(n) );
	
	itemLlist1.select(0, true);
	
	var listSize = itemLlist1.get_item_count();
	for n in range( listSize-1 ):
		if ( PlugTileDrawNode.layers.Lnum.size() <  listSize  ):
			PlugTileDrawNode.layers.Lnum.append( {} ); 


func btn_UpLayer_pressed(): # move layers UP
	var listSize = itemLlist1.get_item_count();
	PlugTileDrawNode.layerMax = listSize;
	#PlugTileDrawNode.add_layers();
	
	var itemListSize = itemLlist1.get_item_count();
	var itemListSelectedItems = itemLlist1.get_selected_items();
	
	for n in itemListSize:
		if ( itemListSelectedItems.has(n) && n >= 1 ):
			if ( itemListSelectedItems[0] != 0 ):
				#itemLlist1.move_item(n, n - 1);
				itemLlist1.move_item(itemListSelectedItems[0], n - 1);
				
				var a1 = PlugTileDrawNode.layers.Lnum[n-1];
				var a2 = PlugTileDrawNode.layers.Lnum[n];
				PlugTileDrawNode.layers.Lnum[n] = a1;
				PlugTileDrawNode.layers.Lnum[n-1] = a2;

This things cant communicate with one an other... I have to pass them on to the other using a var.
If i had an itemList on both sides the result would be the same

EditorInspectorPlugin, doesnt have proccess() nor ready() the user selects the options there...
And putting this layers.Lnum in an itemList i dont know if its possible, i dont know whats going on inside an itemList ?
I dont know if its an array or sometimes its already an array, drawing the list in the draw function could be possible i just dont know how.

So the ItemList represents your layers array?

yes
but itemList only returns an array with get_selected_items()

if i could get all the items on itemlist without having them selected maybe it could use it with the array on the other side
[edit] in the func process() also on the other side since EditorInspectorPlugin doesnt have process(), but it leads to a lot of confusion i have buttons to add and remove (layers)

p.s. chatGPT creates a loop

xyz
I wanted to get an array from itemList
and set the layers.Lnum array on the other side, to be equal to that array

The problem is i have buttons to move items up or down, and to add or remove items
I dont know how to make an array out of itemList without having to update it on all the buttons, and copy / paste all the layers multiple times, even if its possible it would be a waste to have 2 vars for each item... itemList would only function has a picture
