Menu | Electron

Create application menus and context menus.
The presentation of menus varies depending on the operating system:
[!TIP] See also: A detailed guide about how to implement menus in your application.
[!WARNING] Electron's built-in classes cannot be subclassed in user code. For more information, see the FAQ.
Die Menu Klasse hat folgende statische Methoden:
Setzt menu als Anwendungsmenü auf macOS. On Windows and Linux, the menu will be set as each window's top menu.
On Linux, the menu bar uses GTK theme colors when GTK is available. If GTK cannot initialize, it uses Chromium's built-in light or dark menu colors, following nativeTheme.shouldUseDarkColors.
Unter Windows und Linux kannst du auch ein & im Namen des Top-Level-Elements verwenden, um anzugeben, welcher Buchstabe einen generierten Beschleuniger erhalten soll. For example, using &File for the file menu would result in a generated Alt-F accelerator that opens the associated menu. The indicated character in the button label then gets an underline, and the & character is not displayed on the button label.
In order to escape the & character in an item name, add a preceding &. For example, &&File would result in &File displayed on the button label.
Passing null will suppress the default menu. On Windows and Linux, this has the additional effect of removing the menu bar from the window.
[!NOTE] The default menu will be created automatically if the app does not set one. It contains standard items such as File, Edit, View, and Window.
Returns Menu | null - The application menu, if set, or null, if not set.
[!NOTE] The returned Menu instance doesn't support dynamic addition or removal of menu items. Instance properties can still be dynamically modified.
Sets the colors used to highlight the hovered or keyboard-focused item in every menu the app shows, including context menus and the menu bar's dropdowns. Light and dark colors are set separately, and any color left unset keeps the default for that mode. Each call replaces the colors set by any previous call. Passing null restores the defaults.
Menus opened after the call use the new colors. The colors are not applied while Windows high contrast mode or forced colors are active, so the user's system colors take priority.
This method has no effect on macOS and Linux.
Sends the action to the first responder of application. This is used for emulating default macOS menu behaviors. Usually you would use the role property of a MenuItem.
See the macOS Cocoa Event Handling Guide for more information on macOS' native actions.
Generally, the template is an array of options for constructing a MenuItem. The usage can be referenced above.
You can also attach other fields to the element of the template and they will become properties of the constructed menu items.
Das menu Objekt hat die folgenden Instanz Methoden:
Pops up this menu as a context menu in the BaseWindow.
[!TIP] For more details, see the Context Menu guide.
Closes the context menu in the window.
Fügt dem Menü das menuItem hinzu.
Returns MenuItem | null - the item with the specified id
Füre das menuItem an der pos Position im Menü ein.
Objects created with new Menu or returned by Menu.buildFromTemplate emit the following events:
[!NOTE] Some events are only available on specific operating systems and are labeled as such.
Emitted when menu.popup() is called.
Emitiert wenn ein Popup manuell oder mit menu.closePopup() geschlossen wird.
menu objects also have the following properties:
A MenuItem[] array containing the menu's items.
Each Menu consists of multiple MenuItem instances and each MenuItem can nest a Menu into its submenu property.
