Get_range for children in tree

Help
1

I’ve gotten some help here to make a tree with a range. With a tree node and the code:

func _ready():
	var root = quest_tree.create_item()
	root.set_text(0, "Settings")
	
	var section1 = quest_tree.create_item(root)
	section1.set_range(0, 2)
	section1.set_cell_mode(0, TreeItem.CELL_MODE_RANGE)
	section1.set_editable(0, true)
	section1.set_range_config(0, 0, 10, 1)

	var section2 = quest_tree.create_item(root)
	section2.set_range(0, 2)
	section2.set_cell_mode(0, TreeItem.CELL_MODE_RANGE)
	section2.set_editable(0, true)
	section2.set_range_config(0, 0, 10, 1)

I get:

Now I need to grab all the values from this list, i.e. 5 and 2.

I see that I need to use get_range() this should grab the value.

However I don’t understand the syntax. What I’ve tried is:
var children = quest_tree.get_root().get_children()
This returns an array with all treelist items in it, and it seems like get_range does not work on that?

With this code:

var children = quest_tree.get_root().get_children()

# try to get value of first child (value is 5)
print(children.get_range(0))]

I get the error:
Invalid call. Nonexistent function ‘get_range’ in base ‘Array[TreeItem]’.

I think you’ve missed a layer - get_children() gives you an array of TreeItem, get_range() is called on a single TreeItem. You will need to identify which item in the array so the following code will give you the value from the first column of the first array record :-

print(children[0].get_range(0))

works like a charm, thank you @gridsquat
