The tree can have multiple columns with custom controls like text editing, 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 if a dummy hidden root is added. - [codeblock] + [codeblocks] + [gdscript] func _ready(): var tree = Tree.new() var root = tree.create_item() - tree.set_hide_root(true) + 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") - [/codeblock] + [/gdscript] + [csharp] + public override void _Ready() + { + var tree = new Tree(); + TreeItem root = tree.CreateItem(); + tree.HideRoot = true; + TreeItem child1 = tree.CreateItem(root); + TreeItem child2 = tree.CreateItem(root); + TreeItem subchild1 = tree.CreateItem(child1); + subchild1.SetText(0, "Subchild1"); + } + [/csharp] + [/codeblocks] To iterate over all the [TreeItem] objects in a [Tree] object, use [method TreeItem.get_next] and [method TreeItem.get_children] after getting the root through [method get_root].
