Representing Files in a BrowserWindow
Обзор
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.
Для установления представленного файла можно использовать BrowserWindow.setRepresentedFilename и BrowserWindow.setDocumentEdited APIs.
Пример
- main.js
- index.html
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()
}
})
