Build YUI's reusable control, layout, interaction, text, accessibility, and retained-rendering models.

```yh
external thing yuiTreeNode
```

- text id: Stores id as text.
- text parentId: Stores parent id as text.
- text componentName: Stores component name as text.
- text componentRole: Stores component role as text.
- text properties: Stores properties as text.
- int order: Stores order as int.
- bool visible: Stores visible as bool.
- bool enabled: Stores enabled as bool.
- bool mounted: Stores mounted as bool.
- bool disposed: Stores disposed as bool.
- yuiTreeNode(text id, text parentId, yuiComponentMetadata component, text properties, int order): Yui tree node.
- Describe() returns text: Describe.

## Use yuiTreeNode

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using ui

// Build YUI's reusable control, layout, interaction, text, accessibility, and retained-rendering models.
yuiTreeNode sample = yuiTreeNode("id", "parent Id", yuiComponentMetadata("Nova", "role", "property Schema", "child Rule", "defaults", "example", "design Label", true), "properties", 1)
Console.Log(Text.From(sample.id))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.ui__yuitreenode"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "graphics.image"
version = "0.1.0"
path = "../../../yeho/packages/graphics/image"

[[dependencies]]
package = "graphics.text"
version = "0.1.0"
path = "../../../yeho/packages/graphics/text"

[[dependencies]]
package = "host.ui_services"
version = "0.1.0"
path = "../../../yeho/packages/host/ui_services"

[[dependencies]]
package = "ui"
version = "0.2.0"
path = "../../../yeho/packages/ui"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/ui--yuiTreeNode/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## yuiTreeNode.Describe

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using ui

// Describe.
yuiTreeNode instance = yuiTreeNode("id", "parent Id", yuiComponentMetadata("Nova", "role", "property Schema", "child Rule", "defaults", "example", "design Label", true), "properties", 1)
text result = instance.Describe()
Console.Log(Text.From(result))

```

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
