setRoot

Description

Sets a new root node for the Treeview object. This can be useful if you want to replace the current root node with a child node or an entirely new node.

Parameters

1. node The new root node for the Treeview object. This should be a valid Treeview node object.

Returns

1. object The object in use

Usage

• Creates a Treeview, adds a child node, and then sets the child node as the new root node:

local basalt = require("basalt")

local mainFrame = basalt.createFrame()
local treeview = mainFrame:addTreeview()

local childNode = treeview:getRoot().addChild("New Child")
treeview:setRoot(childNode)

basalt.autoUpdate()

In this example, a Treeview object is created and added to the mainFrame. The getRoot method is used to access the root node, and a new child node is added to it with the addChild method. Then, the setRoot method is used to set the new child node as the root node of the Treeview object.
