Package: window.multi | Status: source-declared

Tags: cpu, method, multi, source-example, thing, window, window.multi, yeho

Describe multiple windows, input events, lifecycle, and capabilities with typed records.

```yh
external thing nativePointerContactChange
```

- text kind: Stores kind as text.
- nativePointerRecord pointer: Stores pointer as nativePointerRecord.
- nativePointerContactChange(text kind, nativePointerRecord pointer): Native pointer contact change.
- Fingerprint() returns text: Fingerprint.

## Use nativePointerContactChange

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

Verification: type checked

```yh
using window.multi

// Describe multiple windows, input events, lifecycle, and capabilities with typed records.
nativePointerContactChange sample = nativePointerContactChange("kind", nativePointerRecord("window Id", 1, 1, "pointer Type", "buttons", 1, 1, 1, 1, 1, 1, 1, 1, true, true, true))
Console.Log(Text.From(sample.kind))

```

Save this beside start.yh as project.mech:

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

[app]
kind = "headless"

[[dependencies]]
package = "window.multi"
version = "0.1.0"
path = "../../../yeho/packages/window/multi"

```

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/window.multi--nativePointerContactChange/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## nativePointerContactChange.Fingerprint

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

Verification: type checked

```yh
using window.multi

// Fingerprint.
nativePointerContactChange instance = nativePointerContactChange("kind", nativePointerRecord("window Id", 1, 1, "pointer Type", "buttons", 1, 1, 1, 1, 1, 1, 1, 1, true, true, true))
text result = instance.Fingerprint()
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.
