Menu
Menu API requires node-webkit >= 0.3.0
Menu represents a native menu, it can be used as window menu or context menu.
// Load native UI library
var gui = require('nw.gui');
// Create an empty menu
var menu = new gui.Menu();
// Add some items
menu.append(new gui.MenuItem({ label: 'Item A' }));
menu.append(new gui.MenuItem({ label: 'Item B' }));
menu.append(new gui.MenuItem({ type: 'separator' }));
menu.append(new gui.MenuItem({ label: 'Item C' }));
// Remove one item
menu.removeAt(1);
// Popup as context menu
menu.popup(10, 10);
// Iterate menu's items
for (var i = 0; i < menu.items.length; ++i) {
console.log(menu.items[i]);
}Create a new Menu.
If no option is specified, a normal context menu will be created. To create a menu to be used as window's menu, you need to explicitly specify 'type': 'menubar' in the option, e.g. new Menu({ 'type': 'menubar' }).
Get an array that contains all items of a menu. Each item is a MenuItem.
Append item of MenuItem type to the tail of the Menu.
Insert item of MenuItem type to the ith position of the Menu, Menu is 0-indexed.
Remove item from Menu. This method requires you to keep the MenuItem outside the Menu.
Remove the ith item form Menu
Popup the Menu at position (x, y) in current window. Usually you would listen to contextmenu event of DOM elements and manually popup the menu:
document.body.addEventListener('contextmenu', function(ev) {
ev.preventDefault();
menu.popup(ev.x, ev.y);
return false;
});In this way, you can precisely choose which menu to show for different elements, and you can update menu elements just before popuping it.
since v0.10.0-rc1
OSX only. Creates the default menus (App, Edit and Window). The items can be manipulated with the items property. The argument appname is used for the title of App menu.
Example:
// Load native UI library
var gui = require('nw.gui');
// Create menu
var menu = new gui.Menu({ type: 'menubar' });
// Create sub-menu
var menuItems = new gui.Menu()
menuItems.append(new gui.MenuItem({ label: 'Custom Menu Item 1' }));
menuItems.append(new gui.MenuItem({ label: 'Custom Menu Item 2' }));
// create MacBuiltin
menu.createMacBuiltin('Sample App',{
hideEdit: true,
hideWindow: true
});
// Append MenuItem as a Submenu
menu.append(
new gui.MenuItem({
label: 'Custom Menu Label',
submenu: menuItems // menu elements from menuItems object
})
);
// Append Menu to Window
gui.Window.get().menu = menu;Since v0.10.1, if desired, you can also hide the "Edit" and "Window" menus when invoking createMacBuiltin like so:
nativeMenuBar.createMacBuiltin("My App", {
hideEdit: true,
hideWindow: true
});Get or set a MenuItem's action.
menu.append(menuitem);
menuitem.click = function() {
console.log('clicked');
};
console.log(menu.items[0].click);
