## 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:
|
|
|
|
```lua
|
|
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.
