# dialog
|
|
|
|
The `dialog` module provides APIs to show native system dialogs, so web
|
|
applications can get the same user experience with native applications.
|
|
|
|
An example of showing a dialog to select multiple files and directories:
|
|
|
|
```javascript
|
|
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 to provide a `BrowserWindow` reference in the `browserWindow` parameter.
|
|
|
|
## dialog.showOpenDialog([browserWindow], [options], [callback])
|
|
|
|
* `browserWindow` BrowserWindow
|
|
* `options` Object
|
|
* `title` String
|
|
* `defaultPath` String
|
|
* `filters` Array
|
|
* `properties` Array - Contains which features the dialog should use, can
|
|
contain `openFile`, `openDirectory`, `multiSelections` and
|
|
`createDirectory`
|
|
* `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:
|
|
|
|
```javascript
|
|
{
|
|
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 could not be both file selector
|
|
and directory selector at the same time, so if you set `properties` to
|
|
`['openFile', 'openDirectory']` on these platforms, a directory selector would
|
|
be showed.
|
|
|
|
## dialog.showSaveDialog([browserWindow], [options], [callback])
|
|
|
|
* `browserWindow` BrowserWindow
|
|
* `options` Object
|
|
* `title` String
|
|
* `defaultPath` String
|
|
* `filters` Array
|
|
* `callback` Function
|
|
|
|
On success, returns the path of file chosen by the user, otherwise returns
|
|
`undefined`.
|
|
|
|
The `filters` specifies an array of file types that can be displayed, see
|
|
`dialog.showOpenDialog` for an example.
|
|
|
|
If a `callback` is passed, the API call would be asynchronous and the result
|
|
would be passed via `callback(filename)`
|
|
|
|
## dialog.showMessageBox([browserWindow], [options], [callback])
|
|
|
|
* `browserWindow` BrowserWindow
|
|
* `options` Object
|
|
* `type` String - Can be `"none"`, `"info"` or `"warning"`
|
|
* `buttons` Array - Array of texts for buttons
|
|
* `title` String - Title of the message box, some platforms will not show it
|
|
* `message` String - Content of the message box
|
|
* `detail` String - Extra information of the message
|
|
* `icon` [NativeImage](native-image.md)
|
|
* `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 would be asynchronous and the result
|
|
would 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.
