# Representing Files in a BrowserWindow
|
|
|
|
## Overview
|
|
|
|
On macOS, you can set a represented file for any window in your application.
|
|
The represented file's icon will be shown in the title bar, and when users
|
|
`Command-Click` or `Control-Click`, a popup with a path to the file will be
|
|
shown.
|
|

|
|
|
|
> NOTE: The screenshot above is an example where this feature is used to indicate the currently opened file in the Atom text editor.
|
|
|
|
You can also set the edited state for a window so that the file icon can
|
|
indicate whether the document in this window has been modified.
|
|
|
|
To set the represented file of window, you can use the
|
|
[BrowserWindow.setRepresentedFilename][setrepresentedfilename] and
|
|
[BrowserWindow.setDocumentEdited][setdocumentedited] APIs.
|
|
|
|
## Example
|
|
|
|
```fiddle docs/fiddles/features/represented-file
|
|
const { app, BrowserWindow } = require('electron/main')
|
|
const os = require('node:os')
|
|
|
|
function createWindow () {
|
|
const win = new BrowserWindow({
|
|
width: 800,
|
|
height: 600
|
|
})
|
|
|
|
win.setRepresentedFilename(os.homedir())
|
|
win.setDocumentEdited(true)
|
|
|
|
win.loadFile('index.html')
|
|
}
|
|
|
|
app.whenReady().then(() => {
|
|
createWindow()
|
|
|
|
app.on('activate', () => {
|
|
if (BrowserWindow.getAllWindows().length === 0) {
|
|
createWindow()
|
|
}
|
|
})
|
|
})
|
|
|
|
app.on('window-all-closed', () => {
|
|
if (process.platform !== 'darwin') {
|
|
app.quit()
|
|
}
|
|
})
|
|
```
|
|
|
|
After launching the Electron application, click on the title with `Command` or
|
|
`Control` key pressed. You should see a popup with the represented file at the top.
