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:

var win = ...;  // window in which to show the dialog
var dialog = require('dialog');
console.log(dialog.showOpenDialog({ properties: [ 'openFile', 'openDirectory', 'multiSelections' ]}));

dialog.showOpenDialog([browserWindow], options, [callback])

• browserWindow BrowserWindow
• options Object
  • title String
  • defaultPath String
  • 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.

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
• callback Function

On success, returns the path of file chosen by the user, otherwise returns undefined.

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
• 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)
