Klasse: Tray#

Fügen Sie Symbole und Kontextmenüs in den Benachrichtigungsbereich des Systems hinzu.

Prozess: Haupt

Tray ist ein EventEmitter.

const { app, Menu, Tray } = require('electron')
let tray = nullapp.whenReady().then(() => {  tray = new Tray('/path/to/my/icon')  const contextMenu = Menu.buildFromTemplate([    { label: 'Item1', type: 'radio' },    { label: 'Item2', type: 'radio' },    { label: 'Item3', type: 'radio', checked: true },    { label: 'Item4', type: 'radio' }  ])  tray.setToolTip('This is my application.')  tray.setContextMenu(contextMenu)})

Plattform-Einschränkungen:

  • Unter Linux wird der App-Indikator verwendet, wenn er unterstützt wird, ansonsten wird GtkStatusIcon verwendet.
  • On Linux distributions that only have app indicator support, you have to install libappindicator1 to make the tray icon work.
  • App-Indikator wird nur angezeigt, wenn es ein Kontextmenü hat.
  • Wenn die App-Anzeige auf Linux verwendet wird, wird das click Ereignis ignoriert.
  • On Linux in order for changes made to individual MenuItems to take effect, you have to call setContextMenu again. Ein Beispiel:
const { app, Menu, Tray } = require('electron')
let appIcon = nullapp.whenReady().then(() => {  appIcon = new Tray('/path/to/my/icon')  const contextMenu = Menu.buildFromTemplate([    { label: 'Item1', type: 'radio' },    { label: 'Item2', type: 'radio' }  ])
  // Make a change to the context menu  contextMenu.items[1].checked = false
  // Call this again for Linux because we modified the context menu  appIcon.setContextMenu(contextMenu)})
  • Unter Windows wird empfohlen, ICO Icons zu verwenden, um beste visuelle Effekte zu erhalten.

If you want to keep exact same behaviors on all platforms, you should not rely on the click event and always attach a context menu to the tray icon.

new Tray(image, [guid])#

  • image (NativeImage | String)
  • guid String (optional) Windows - Assigns a GUID to the tray icon. If the executable is signed and the signature contains an organization in the subject line then the GUID is permanently associated with that signature. OS level settings like the position of the tray icon in the system tray will persist even if the path to the executable changes. If the executable is not code-signed then the GUID is permanently associated with the path to the executable. Changing the path to the executable will break the creation of the tray icon and a new GUID must be used. However, it is highly recommended to use the GUID parameter only in conjunction with code-signed executable. If an App defines multiple tray icons then each icon must use a separate GUID.

Creates a new tray icon associated with the image.
