Control to show a tree of items.
    public class Tree : Control

This shows a tree of items that can be selected, expanded and collapsed. 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.


func _ready():

var tree =

var root = tree.create_item()


var child1 = tree.create_item(root)

var child2 = tree.create_item(root)

var subchild1 = tree.create_item(child1)

subchild1.set_text(0, “Subchild1”)

Emitted when a cell with the CELL_MODE_CUSTOM is clicked to be edited.

    "empty_tree_rmb_selected" (Vector2 position)

Emitted when the right mouse button is pressed if RMB selection is active and the tree is empty.

    "item_activated" ()

Emitted when an item’s label is double-clicked.

    "item_collapsed" (TreeItem item)

    public bool AllowReselect { get; set; }

If true, the currently selected cell may be selected again.

    public bool AllowRmbSelect { get; set; }

If true, a right mouse button click can select items.

    public int Columns { get; set; }

The amount of columns.

    public int DropModeFlags { get; set; }

The drop mode as an OR combination of flags. See DROP_MODE_* constants. Once dropping is done, reverts to DROP_MODE_DISABLED. Setting this during Control.CanDropData(Godot.Vector2, object) is recommended.

    public bool HideFolding { get; set; }

If true, the folding arrow is hidden.

    public bool HideRoot { get; set; }

If true, the tree’s root is hidden.

    public SelectModeEnum SelectMode { get; set; }

Allow single or multiple selection. See the SELECT_* constants.


    public bool AreColumnTitlesVisible()

Returns true if the column titles are being shown.

    public void Clear()

Clears the tree. This removes all items.

    public TreeItem CreateItem(Object parent = null, int idx = -1)

Create an item in the tree and add it as the last child of parent. If parent is not given, it will be added as the root’s last child, or it’ll the be the root itself if the tree is empty.

    public void EnsureCursorIsVisible()

Makes the currently selected item visible. This will scroll the tree to make sure the selected item is visible.

    public bool GetAllowReselect()

Getter for AllowReselect

    public bool GetAllowRmbSelect()

Getter for AllowRmbSelect

    public int GetColumnAtPosition(Vector2 position)
