## **Question**

How do I prevent a window from being refreshed (e.g., F5, Ctrl+R)?

## Answer

Use the `onRefreshing` event on the current window and call `prevent()`:

```auto
io.windows.my().onRefreshing((prevent) => {
    prevent();
});

```

## Question

How do I prevent a window from being closed?

## Answer

Use `onClosing` the same way. Pass `{ showDialog: false }` to suppress the default confirmation dialog:

```auto
io.windows.my().onClosing((prevent) => {
    prevent({ showDialog: false });
});

```

## Question

Can I also intercept navigation away from the page?

## Answer

Yes. The same `prevent()` pattern is available on three window lifecycle events: `onClosing`, `onRefreshing`, and `onNavigating`.

## Question

Can I enable these handlers through configuration instead of code?

## Answer

Yes. Close and refresh handlers can be enabled globally or per application in the system configuration via the `closeHandlers` and `refreshHandlers` properties.
