setExpanded

Description

The setExpanded method sets the expanded state of a specified node within a Treeview object. When a node is expanded, its children nodes are displayed. If a node is collapsed, its children nodes are hidden.

Parameters

  1. boolean The expanded state to set for the node (true for expanded, false for collapsed)

Returns

  1. object The object in use

Usage

  • Creates a Treeview, adds a child node to the root node, and sets the expanded state to false:
local basalt = require("basalt")

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

local rootNode = treeview:getRoot()
local childNode = rootNode.addChild("Child Node")

rootNode.setExpanded(false)

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 using the addChild method. The setExpanded method is then used to set the expanded state of the root node to false, hiding its children nodes.
