Menu
I am planning to realize a music player with electron. It will list music from the user’s hard drive.
Is it possible to define a drag’n’drop behavior so that I can drag a html element, e.g. <span>Artist – Title</span> outside the electron window onto the user’s desktop to copy the actual file?
File is stored here: ~/music/Artist-Title.mp3.
When drag’n’dropping the spanfrom my electron window onto the desktop a copy should be made: ~/Desktop/Artist-Title.mp3.

Working example:
Put into main.js and copy an icon to be shown while dragging (yourAppDir/img/icon/folder.png):
const {ipcMain} = require('electron')
ipcMain.on('ondragstart', (event, filePath) => {
event.sender.startDrag({
file: filePath,
icon: 'img/icon/folder.png'
})
})
Put into renderer.js, and set the path to the file you want to drop out:
var ipcRenderer = require('electron').ipcRenderer
document.getElementById('drag').ondragstart = (event) => {
event.preventDefault()
ipcRenderer.send('ondragstart', '/Users/tim/dev/test/elektron-drag-out-test/img/icon/folder.png')
}
Create the draggable element inside the body tags of index.html:
...
<body>
...
<a href="#" id="drag" class="draggable">drag item</a>
</body>
...
I also created a gist for drag in / out.
Another helpful resource: Electron – Add webContents.startDrag(item) API

I believe this is the API you are looking for.
http://electron.atom.io/docs/api/web-contents/#contentsstartdragitem
remote.getCurrentWebContents().startDrag({
file: 'path/to/file',
icon: 'path/to/file/icon',
});
