# useZoomLevel
|
|
|
|
Reactive [WebFrame](https://www.electronjs.org/docs/api/web-frame#webframe) zoom level.
|
|
|
|
## Usage
|
|
|
|
```ts
|
|
import { useZoomLevel } from '@vueuse/electron'
|
|
|
|
// enable nodeIntegration if you don't provide webFrame explicitly
|
|
// see: https://www.electronjs.org/docs/api/webview-tag#nodeintegration
|
|
// Ref result will return
|
|
const level = useZoomLevel()
|
|
console.log(level.value) // print current zoom level
|
|
level.value = 2 // change current zoom level
|
|
```
|
|
|
|
Set initial zoom level immediately
|
|
|
|
```ts
|
|
import { useZoomLevel } from '@vueuse/electron'
|
|
|
|
const level = useZoomLevel(2)
|
|
```
|
|
|
|
Pass a `ref` and the level will be updated when the source ref changes
|
|
|
|
```ts
|
|
import { useZoomLevel } from '@vueuse/electron'
|
|
import { shallowRef } from 'vue'
|
|
|
|
const level = shallowRef(1)
|
|
|
|
useZoomLevel(level) // zoom level will match with the ref
|
|
|
|
level.value = 2 // zoom level will change
|
|
```
|
|
|
|
## Type Declarations
|
|
|
|
```ts
|
|
export declare function useZoomLevel(level: MaybeRef<number>): Ref<number>
|
|
export declare function useZoomLevel(
|
|
webFrame: WebFrame,
|
|
level: MaybeRef<number>,
|
|
): Ref<number>
|
|
export declare function useZoomLevel(webFrame: WebFrame): Ref<number>
