# Progress Bar in Taskbar (Windows, macOS, Unity)
|
|
|
|
On Windows a taskbar button can be used to display a progress bar. This enables
|
|
a window to provide progress information to the user without the user having to
|
|
switch to the window itself.
|
|
|
|
On macOS the progress bar will be displayed as a part of the dock icon.
|
|
|
|
The Unity DE also has a similar feature that allows you to specify the progress
|
|
bar in the launcher.

|
|
All three cases are covered by the same API - the `setProgressBar()` method
|
|
available on instances of `BrowserWindows`. Call it with a number between `0`
|
|
and `1` to indicate your progress. If you have a long-running task that's
|
|
currently at 63% towards completion, you'd call it with `setProgressBar(0.63)`.
|
|
|
|
Generally speaking, setting the parameter to a value below zero (like `-1`)
|
|
will remove the progress bar while setting it to a value higher than one
|
|
(like `2`) will switch the progress bar to intermediate mode.
|
|
|
|
See the [API documentation for more options and modes][setprogressbar].

```javascript
|
|
const { BrowserWindow } = require('electron')
|
|
const win = new BrowserWindow()
|
|
|
|
win.setProgressBar(0.5)
|
|
```
