Tree

Inherits: Control < CanvasItem < Node < Object

A control used to show a set of internal TreeItems in a hierarchical structure.

Description

A control used to show a set of internal TreeItems in a hierarchical structure. The tree items can be selected, expanded and collapsed. The tree can have multiple columns with custom controls like LineEdits, buttons and popups. It can be useful for structured displays and interactions.

Trees are built via code, using TreeItem objects to create the structure. They have a single root, but multiple roots can be simulated with hide_root:

func _ready():
    var tree = Tree.new()
    var root = tree.create_item()
    tree.hide_root = true
    var child1 = tree.create_item(root)
    var child2 = tree.create_item(root)
    var subchild1 = tree.create_item(child1)
    subchild1.set_text(0, "Subchild1")
