<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
|
||
|
|
error dialog.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
You can use an error dialog before the app's
|
||
|
|
<code>ready</code> event, which is useful for showing errors upon
|
||
|
|
startup.
