Using images from application resources is very simple. Suppose we have a PNG image that is placed in the `resources` directory in our project. For this tutorial we will use the image sample:

<imgalt="Sample"src="sample.png"height="500"/>

Note the annotation `@OptIn(ExperimentalComposeUiApi::class)`. Some keys related APIs are still an experimental feature of Compose, and later API changes are possible. So it requires the use of a special annotation to emphasize the experimental nature of the code.
To move focus in custom order we need to create a `FocusRequester` and apply the `Modifier.focusOrder` modifier to each component you want to navigate.
If the window requires some custom logic on close (for example, to show a dialog), you can override the close action using `onCloseRequest`.

If an application has multiple windows, then it is better to put its state into a separate class and open/close window in response to `mutableStateListOf` changes (see [notepad example](https://github.com/JetBrains/compose-jb/tree/master/examples/notepad) for more complex use cases):

Reading the state in composition is useful when you need to update UI, but there are cases when you need to react to the state changes and send a value to another non-composable level of your application (write it to the database, for example):
