dialog
The dialog
module provides APIs to show native system dialogs, so web
applications can deliver the same user experience as native applications.
An example of showing a dialog to select multiple files and directories:
var win = ...; // window in which to show the dialog
var dialog = require('dialog');
console.log(dialog.showOpenDialog({ properties: [ 'openFile', 'openDirectory', 'multiSelections' ]}));
Note for OS X: If you want to present dialogs as sheets, the only thing you have to do is provide a BrowserWindow
reference in the browserWindow
parameter.
dialog.showOpenDialog([browserWindow], [options], [callback])
browserWindow
BrowserWindowoptions
Objecttitle
StringdefaultPath
Stringfilters
Arrayproperties
Array - Contains which features the dialog should use, can containopenFile
,openDirectory
,multiSelections
andcreateDirectory
callback
Function
On success, returns an array of file paths chosen by the user, otherwise
returns undefined
.
The filters
specifies an array of file types that can be displayed or
selected, an example is:
{
filters: [
{ name: 'Images', extensions: ['jpg', 'png', 'gif'] },
{ name: 'Movies', extensions: ['mkv', 'avi', 'mp4'] },
{ name: 'Custom File Type', extensions: ['as'] }
]
}
If a callback
is passed, the API call would be asynchronous and the result
would be passed via callback(filenames)
Note: On Windows and Linux, an open dialog can not be both a file selector
and a directory selector, so if you set properties
to
['openFile', 'openDirectory']
on these platforms, a directory selector will be shown.

callback
Function
Shows a message box, it will block until the message box is closed. It returns the index of the clicked button.
If a callback
is passed, the API call will be asynchronous and the result
will be passed via callback(response)
dialog.showErrorBox(title, content)
Runs a modal dialog that shows an error message.
This API can be called safely before the ready
event of app
module emits, it
is usually used to report errors in early stage of startup.
