托盘
概述
本指南将引导您完成创建具有自身上下文菜单的托盘图标到系统通知区域的过程。
在 MacOS 和 Ubuntu 上,托盘将位于屏幕的右上角,紧邻电池和 Wi-Fi 图标。在 Windows 上,托盘通常位于右下角。
示例
main.js
首先,我们必须从 electron
中导入 app
、Tray
、Menu
、nativeImage
。
const { app, Tray, Menu, nativeImage } = require('electron')
接下来,我们将创建我们的托盘。为此,我们将使用NativeImage
图标,可以通过这些方法中的任何一个创建。请注意,我们将托盘创建代码包装在app.whenReady
中,因为我们需要等待 Electron 应用完成初始化。
main.js
let tray
app.whenReady().then(() => {
const icon = nativeImage.createFromPath('path/to/asset.png')
tray = new Tray(icon)
// note: your contextMenu, Tooltip and Title code will go here!
})
太棒了!现在我们可以开始将上下文菜单附加到我们的托盘,如下所示
const contextMenu = Menu.buildFromTemplate([
{ label: 'Item1', type: 'radio' },
{ label: 'Item2', type: 'radio' },
{ label: 'Item3', type: 'radio', checked: true },
{ label: 'Item4', type: 'radio' }
])
tray.setContextMenu(contextMenu)
以上代码将在上下文菜单中创建 4 个单独的单选类型项目。要详细了解如何构建原生菜单,请点击此处。
最后,让我们为托盘提供一个工具提示和标题。
tray.setToolTip('This is my application')
tray.setTitle('This is my title')
结论
启动 Electron 应用后,您应该会看到托盘驻留在屏幕的右上或右下角,具体取决于您的操作系统。

The <code>tray</code> module allows you to create an icon in the
operating system's notification area.

<h2>ProTip</h2>
<strong>Tray support in Linux.</strong>
<p>
On Linux distributions that only have app indicator support, users
will need to install <code>libappindicator1</code> to make the
tray icon work. See the
<a href="https://www.electron.js.cn/docs/latest/api/tray">
full API documentation

for more details about using Tray on Linux.
