1. Tray(托盘图片)消失
假如你把 tray
的实例变量定义在了函数内部(比如 app.on('ready', createWindow)
的回调函数内),那么当 JavaScript 引擎进行垃圾回收的时候,这个变量就会被销毁,这样 tray 的实例就没了,托盘图标就消失了。
2. 无法进行复制、粘贴之类的操作
由于默认没有绑定任何快捷键,当然操作不了,使用官方提供的下面这段代码,将各平台所有常见的菜单(快捷键)绑定好。
const template = [
{
label: 'Edit',
submenu: [
{role: 'undo'},
{role: 'redo'},
{type: 'separator'},
{role: 'cut'},
{role: 'copy'},
{role: 'paste'},
{role: 'pasteandmatchstyle'},
{role: 'delete'},
{role: 'selectall'}
]
},
{
label: 'View',
submenu: [
{role: 'reload'},
{role: 'forcereload'},
{role: 'toggledevtools'},
{type: 'separator'},
{role: 'resetzoom'},
{role: 'zoomin'},
{role: 'zoomout'},
{type: 'separator'},
{role: 'togglefullscreen'}
]
},
{
role: 'window',
submenu: [
{role: 'minimize'},
{role: 'close'}
]
},
{
role: 'help',
submenu: [
{
label: 'Learn More',
click () { require('electron').shell.openExternal('https://electron.atom.io') }
}
]
}
]
if (process.platform === 'darwin') {
template.unshift({
label: app.getName(),
submenu: [
{role: 'about'},
{type: 'separator'},
{role: 'services', submenu: []},
{type: 'separator'},
{role: 'hide'},
{role: 'hideothers'},
{role: 'unhide'},
{type: 'separator'},
{role: 'quit'}
]
})
// Edit menu
template[1].submenu.push(
{type: 'separator'},
{
label: 'Speech',
submenu: [
{role: 'startspeaking'},
{role: 'stopspeaking'}
]
}
)
// Window menu
template[3].submenu = [
{role: 'close'},
{role: 'minimize'},
{role: 'zoom'},
{type: 'separator'},
{role: 'front'}
]
}
