Godot 4 plugin development: dump parts of the interface tree to look for controls

dump_tree_example.gd

@tool
## (can be any Node as long as it's a tool)
extends EditorPlugin 

func _enter_tree():
	# print root
	_dump_interface(EditorInterface.get_base_control(), 2)  
	# found by looking at the dump
	var animation_player_editor = EditorInterface.get_base_control().find_child("*AnimationPlayerEditor*", true, false)
	_dump_interface(animation_player_editor, 2)


## Will print the tree (use with care, because your plugin will probably not be forward compatible across versions)
func _dump_interface(n : Node, max_d : int = 2, d : int = 0) -> void:
	if n.name.contains("Dialog") or n.name.contains("Popup"):
		return
	print(n.name.lpad(d + n.name.length(), "-") + " (%d)" % [n.get_child_count()])
	for c in n.get_children():
		if d < max_d:
			_dump_interface(c, max_d, d + 1)
