<h1>Use system dialogs</h1>
<h3>
The <code>dialog</code> module in Electron allows you to use native
system dialogs for opening files or directories, saving a file or
displaying informational messages.
</h3>
<p>
This is a main process module because this process is more efficient
with native utilities and it allows the call to happen without
interrupting the visible elements in your page's renderer process.

<h2>Open a File or Directory</h2>
<div>
<div>
<button id="select-directory">View Demo</button>
<span id="selected-file"></span>
</div>
<p>
In this demo, the <code>ipc</code> module is used to send a message
from the renderer process instructing the main process to launch the
open file (or directory) dialog. If a file is selected, the main
process can send that information back to the renderer process.
</p>
<h5>Renderer Process</h5>
<pre>
<code>
const {ipcRenderer} = require('electron')
const selectDirBtn = document.getElementById('select-directory')
selectDirBtn.addEventListener('click', (event) => {
ipcRenderer.send('open-file-dialog')
})
ipcRenderer.on('selected-directory', (event, path) => {
document.getElementById('selected-file').innerHTML = `You selected: ${path}`
})
</code>
</pre>
<h5>Main Process</h5>
<pre>
<code>
const {ipcMain, dialog} = require('electron')
ipcMain.on('open-file-dialog', (event) => {
dialog.showOpenDialog({
properties: ['openFile', 'openDirectory']
}, (files) => {
if (files) {
event.sender.send('selected-directory', files)
}
})
})
</code>
</pre>
<div>
<h2>ProTip</h2>
<strong>The sheet-style dialog on macOS.</strong>
<p>
On macOS you can choose between a "sheet" dialog or a default
dialog. The sheet version descends from the top of the window. To
use sheet version, pass the <code>window</code> as the first
argument in the dialog method.
</p>
<pre><code class="language-js">const ipc = require('electron').ipcMain
const dialog = require('electron').dialog
const BrowserWindow = require('electron').BrowserWindow
ipc.on('open-file-dialog-sheet', function (event) {
const window = BrowserWindow.fromWebContents(event.sender)
const files = dialog.showOpenDialog(window, { properties: [ 'openFile' ]})
})</code></pre>
</div>
</div>

<script>
// You can also require other files to run in this process
