<div>
<a href="#" id="drag-file-link">Drag Demo</a>
</div>
<p>
Click and drag the link above to copy the renderer process
javascript file on to your machine.
</p>
<p>
In this demo, the <code>webContents.startDrag()</code> API is called
in response to the <code>ondragstart</code> event.
</p>
<h5>Renderer Process</h5>
<pre><code>
const {ipcRenderer} = require('electron')
const dragFileLink = document.getElementById('drag-file-link')
dragFileLink.addEventListener('dragstart', (event) => {
event.preventDefault()
ipcRenderer.send('ondragstart', __filename)
})
</code></pre>
<h5>Main Process</h5>
<pre>
<code>
const {ipcMain} = require('electron')
const path = require('path')
ipcMain.on('ondragstart', (event, filepath) => {
const iconName = 'codeIcon.png'
event.sender.startDrag({
file: filepath,
icon: path.join(__dirname, iconName)
})
})
</code></pre>
</div>
</div>
</div>
<script>
// You can also require other files to run in this process
require("./renderer.js");
</script>
