<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.

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
|
|
information dialog. Options may be provided for responses which can
|
|
then be relayed back to the renderer process.
|
|
</p>
|
|
|
|
<p>
|
|
Note: The <code>title</code> property is not displayed in macOS.
|
|
</p>
|
|
|
|
<p>
|
|
An information dialog can contain an icon, your choice of buttons,
|
|
title and message.
