Also on Windows and Linux, you can use a & in the top-level item name to indicate which letter should get a generated accelerator. 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 proceeding &. 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, Window and Help.

`Menu.getApplicationMenu()`

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.

`Menu.sendActionToFirstResponder(action)` macOS

action string

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.

`Menu.buildFromTemplate(template)`

template (MenuItemConstructorOptions | MenuItem)[]

Returns Menu

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.
