BaseWindow
BaseWindow
创建和控制窗口。
¥Create and control windows.
进程：主进程
¥Process: Main
注意
BaseWindow提供了一种在单个窗口中组合多个 Web 视图的灵活方法。对于只有一个全尺寸 Web 视图的窗口，BrowserWindow类可能是一个更简单的选择。¥
BaseWindowprovides a flexible way to compose multiple web views in a single window. For windows with only a single, full-size web view, theBrowserWindowclass may be a simpler option.
在 app 模块的 ready 事件发出之前，该模块无法使用。
¥This module cannot be used until the ready event of the app
module is emitted.
// In the main process.
const { BaseWindow, WebContentsView } = require('electron')
const win = new BaseWindow({ width: 800, height: 600 })
const leftView = new WebContentsView()
leftView.webContents.loadURL('https://electron.nodejs.cn')
win.contentView.addChildView(leftView)
const rightView = new WebContentsView()
rightView.webContents.loadURL('https://github.com/electron/electron')
win.contentView.addChildView(rightView)
leftView.setBounds({ x: 0, y: 0, width: 400, height: 600 })
rightView.setBounds({ x: 400, y: 0, width: 400, height: 600 })
父窗口和子窗口
¥Parent and child windows
通过使用 parent 选项，你可以创建子窗口：
¥By using parent option, you can create child windows:
const { BaseWindow } = require('electron')
const parent = new BaseWindow()
const child = new BaseWindow({ parent })
child 窗口将始终显示在 parent 窗口的顶部。
¥The child window will always show on top of the parent window.
模态窗口
¥Modal windows
模态窗口是禁用父窗口的子窗口。要创建模态窗口，你必须设置 parent 和 modal 选项：
¥A modal window is a child window that disables parent window. To create a modal
window, you have to set both the parent and modal options:
const { BaseWindow } = require('electron')
const parent = new BaseWindow()
const child = new BaseWindow({ parent, modal: true })
平台须知
¥Platform notices
在 macOS 上，模式窗口将显示为附加到父窗口的工作表。
¥On macOS modal windows will be displayed as sheets attached to the parent window.
在 macOS 上，当父窗口移动时，子窗口将保持与父窗口的相对位置，而在 Windows 和 Linux 上，子窗口不会移动。
¥On macOS the child windows will keep the relative position to parent window when parent window moves, while on Windows and Linux child windows will not move.
在 Linux 上，模式窗口的类型将更改为
dialog。¥On Linux the type of modal windows will be changed to
dialog.在 Linux 上，许多桌面环境不支持隐藏模式窗口。
¥On Linux many desktop environments do not support hiding a modal window.

BaseWindow 是 EventEmitter。
¥BaseWindow is an EventEmitter.
它创建一个新的 BaseWindow，其原生属性由 options 设置。
¥It creates a new BaseWindow with native properties as set by the options.
new BaseWindow([options])
当使用 minWidth/maxWidth/minHeight/maxHeight 设置最小或最大窗口大小时，它仅限制用户。它不会阻止你将不遵循大小限制的大小传递给 setBounds/setSize 或 BrowserWindow 的构造函数。
¥When setting minimum or maximum window size with minWidth/maxWidth/
minHeight/maxHeight, it only constrains the users. It won't prevent you from
passing a size that does not follow size constraints to setBounds/setSize or
to the constructor of BrowserWindow.
type 选项的可能值和行为取决于平台。可能的值为：
¥The possible values and behaviors of the type option are platform dependent.
Possible values are:
在 Linux 上，可能的类型为
desktop、dock、toolbar、splash、notification。¥On Linux, possible types are
desktop,dock,toolbar,splash,notification.desktop类型将窗口放置在桌面背景窗口级别 (kCGDesktopWindowLevel - 1)。但请注意，桌面窗口不会接收焦点、键盘或鼠标事件。你仍然可以使用 globalShortcut 来谨慎地接收输入。¥The
desktoptype places the window at the desktop background window level (kCGDesktopWindowLevel - 1). However, note that a desktop window will not receive focus, keyboard, or mouse events. You can still use globalShortcut to receive input sparingly.dock类型创建类似停靠的窗口行为。¥The
docktype creates a dock-like window behavior.toolbar类型创建一个带有工具栏外观的窗口。¥The
toolbartype creates a window with a toolbar appearance.splash类型以特定方式运行。即使窗口主体的 CSS 样式包含 -webkit-app-region，它也是不可拖动的：拖。这种类型通常用于启动画面。¥The
splashtype behaves in a specific way. It is not draggable, even if the CSS styling of the window's body contains -webkit-app-region: drag. This type is commonly used for splash screens.notification类型创建一个行为类似于系统通知的窗口。¥The
notificationtype creates a window that behaves like a system notification.
在 macOS 上，可能的类型为
desktop、textured、panel。¥On macOS, possible types are
desktop,textured,panel.textured型增加了金属渐变外观（NSWindowStyleMaskTexturedBackground）。¥The
texturedtype adds metal gradient appearance (NSWindowStyleMaskTexturedBackground).desktop类型将窗口放置在桌面背景窗口级别 (kCGDesktopWindowLevel - 1)。请注意，桌面窗口不会接收焦点、键盘或鼠标事件，但你可以使用globalShortcut来少量接收输入。¥The
desktoptype places the window at the desktop background window level (kCGDesktopWindowLevel - 1). Note that desktop window will not receive focus, keyboard or mouse events, but you can useglobalShortcutto receive input sparingly.panel类型通过在运行时添加NSWindowStyleMaskNonactivatingPanel样式掩码（通常为 NSPanel 保留），使窗口能够浮动在全屏应用的顶部。此外，该窗口将出现在所有空间（桌面）上。¥The
paneltype enables the window to float on top of full-screened apps by adding theNSWindowStyleMaskNonactivatingPanelstyle mask,normally reserved for NSPanel, at runtime. Also, the window will appear on all spaces (desktops).
在 Windows 上，可能的类型是
toolbar。¥On Windows, possible type is
toolbar.
实例事件
¥Instance Events
使用 new BaseWindow 创建的对象会发出以下事件：
¥Objects created with new BaseWindow emit the following events:
注意：某些事件仅在特定操作系统上可用并如此标记。
¥Note: Some events are only available on specific operating systems and are labeled as such.
事件：'close'
¥Event: 'close'
返回：
¥Returns:
event事件¥
eventEvent
当窗口将要关闭时发出。它在 DOM 的 beforeunload 和 unload 事件之前发出。调用 event.preventDefault() 将取消关闭。
¥Emitted when the window is going to be closed. It's emitted before the
beforeunload and unload event of the DOM. Calling event.preventDefault()
will cancel the close.
通常你会希望使用 beforeunload 处理程序来决定是否应关闭窗口，重新加载窗口时也会调用该处理程序。在 Electron 中，返回 undefined 以外的任何值都会取消关闭。例如：
¥Usually you would want to use the beforeunload handler to decide whether the
window should be closed, which will also be called when the window is
reloaded. In Electron, returning any value other than undefined would cancel the
close. For example:
window.onbeforeunload = (e) => {
console.log('I do not want to be closed')
// Unlike usual browsers that a message box will be prompted to users, returning
// a non-void value will silently cancel the close.
// It is recommended to use the dialog API to let the user confirm closing the
// application.
e.returnValue = false
}
注意：window.onbeforeunload = handler 和 window.addEventListener('beforeunload', handler) 的行为之间存在细微差别。建议始终显式设置 event.returnValue，而不是仅返回一个值，因为前者在 Electron 中工作得更加一致。
¥*Note: There is a subtle difference between the behaviors of window.onbeforeunload = handler and window.addEventListener('beforeunload', handler). It is recommended to always set the event.returnValue explicitly, instead of only returning a value, as the former works more consistently within Electron.*
事件：'closed'
¥Event: 'closed'
当窗口关闭时发出。收到此事件后，你应该删除对该窗口的引用并避免再使用它。
¥Emitted when the window is closed. After you have received this event you should remove the reference to the window and avoid using it any more.

edge(string) - The edge of the window being dragged for resizing. Can bebottom,left,right,top-left,top-right,bottom-leftorbottom-right.
在调整窗口大小之前发出。调用 event.preventDefault() 将阻止调整窗口大小。
¥Emitted before the window is resized. Calling event.preventDefault() will prevent the window from being resized.
请注意，只有在手动调整窗口大小时才会发出此消息。使用 setBounds/setSize 调整窗口大小不会发出此事件。
¥Note that this is only emitted when the window is being resized manually. Resizing the window with setBounds/setSize will not emit this event.
edge 选项的可能值和行为取决于平台。可能的值为：
¥The possible values and behaviors of the edge option are platform dependent. Possible values are:
在 Windows 上，可能的值为
bottom、top、left、right、top-left、top-right、bottom-left、bottom-right。¥On Windows, possible values are
bottom,top,left,right,top-left,top-right,bottom-left,bottom-right.在 macOS 上，可能的值为

¥Emitted before the window is moved. On Windows, calling event.preventDefault() will prevent the window from being moved.
请注意，只有在手动移动窗口时才会发出此信号。使用 setPosition/setBounds/center 移动窗口不会发出此事件。
¥Note that this is only emitted when the window is being moved manually. Moving the window with setPosition/setBounds/center will not emit this event.
事件：'move'
¥Event: 'move'
当窗口移动到新位置时发出。
¥Emitted when the window is being moved to a new position.

事件：'app-command' Windows Linux
¥Event: 'app-command' Windows Linux
返回：
¥Returns:
event事件¥
eventEventcommand字符串¥
commandstring
当调用 应用命令 时发出。这些通常与键盘媒体键或浏览器命令以及 Windows 上某些鼠标中内置的 "后退" 按钮相关。
¥Emitted when an App Command is invoked. These are typically related to keyboard media keys or browser commands, as well as the "Back" button built into some mice on Windows.
命令变为小写，下划线替换为连字符，并且去掉 APPCOMMAND_ 前缀。例如 APPCOMMAND_BROWSER_BACKWARD 作为 browser-backward 发出。
¥Commands are lowercased, underscores are replaced with hyphens, and the
APPCOMMAND_ prefix is stripped off.
e.g. APPCOMMAND_BROWSER_BACKWARD is emitted as browser-backward.
const { BaseWindow } = require('electron')
const win = new BaseWindow()
win.on('app-command', (e, cmd) => {
// Navigate the window back when the user hits their mouse back button
if (cmd === 'browser-backward') {
// Find the appropriate WebContents to navigate.
}
})
Linux 上明确支持以下应用命令：
¥The following app commands are explicitly supported on Linux:
browser-backwardbrowser-forward
事件：'swipe' macOS
¥Event: 'swipe' macOS
返回：
¥Returns:
event事件¥
eventEventdirection字符串¥
directionstring
三指滑动时发出。可能的方向是 up、right、down、left。
¥Emitted on 3-finger swipe. Possible directions are up, right, down, left.
此事件背后的方法是为了处理旧版 macOS 风格的触控板滑动而构建的，其中屏幕上的内容不会随着滑动而移动。大多数 macOS 触控板不再配置为允许这种滑动，因此为了使其正确发出，System Preferences > Trackpad > More Gestures 中的 '在页面之间滑动' 首选项必须设置为 '用两根或三根手指滑动'。
¥The method underlying this event is built to handle older macOS-style trackpad swiping,
where the content on the screen doesn't move with the swipe. Most macOS trackpads are not
configured to allow this kind of swiping anymore, so in order for it to emit properly the
'Swipe between pages' preference in System Preferences > Trackpad > More Gestures must be
set to 'Swipe with two or three fingers'.
事件：'rotate-gesture' macOS
¥Event: 'rotate-gesture' macOS
返回：
¥Returns:
event事件¥
eventEventrotation漂浮¥
rotationFloat
在触控板旋转手势上发出。持续发出直到旋转手势结束。每次触发的 rotation 值是自上次触发以来旋转的角度（以度为单位）。旋转手势时最后发出的事件的值始终为 0。逆时针旋转值为正，顺时针旋转值为负。
¥Emitted on trackpad rotation gesture. Continually emitted until rotation gesture is
ended. The rotation value on each emission is the angle in degrees rotated since
the last emission. The last emitted event upon a rotation gesture will always be of
value 0. Counter-clockwise rotation values are positive, while clockwise ones are
negative.

单击原生新选项卡按钮时发出。
¥Emitted when the native new tab button is clicked.
事件：'system-context-menu' Windows
¥Event: 'system-context-menu' Windows
返回：
¥Returns:
event事件¥
eventEventpoint观点 - 触发上下文菜单的屏幕坐标¥
pointPoint - The screen coordinates the context menu was triggered at
当在窗口上触发系统上下文菜单时发出，通常仅当用户右键单击窗口的非客户区域时才会触发。这是窗口标题栏或你在无框窗口中声明为 -webkit-app-region: drag 的任何区域。
¥Emitted when the system context menu is triggered on the window, this is
normally only triggered when the user right clicks on the non-client area
of your window. This is the window titlebar or any area you have declared
as -webkit-app-region: drag in a frameless window.
调用 event.preventDefault() 将阻止显示菜单。
¥Calling event.preventDefault() will prevent the menu from being displayed.

win.setAspectRatio(aspectRatio[, extraSize])
aspectRatio漂浮 - 内容视图某些部分保持的宽高比。¥
aspectRatioFloat - The aspect ratio to maintain for some portion of the content view.extraSize尺寸（可选）macOS - 在保持纵横比的同时不包括额外的尺寸。¥
extraSizeSize (optional) macOS - The extra size not to be included while maintaining the aspect ratio.
这将使窗口保持纵横比。额外的尺寸允许开发者拥有以像素指定的空间，不包括在长宽比计算中。该 API 已经考虑了窗口大小与其内容大小之间的差异。
¥This will make a window maintain an aspect ratio. The extra size allows a developer to have space, specified in pixels, not included within the aspect ratio calculations. This API already takes into account the difference between a window's size and its content size.
考虑一个带有高清视频播放器和相关控件的普通窗口。也许左边缘有 15 个像素的控件，右边缘有 25 个像素的控件，播放器下方有 50 个像素的控件。为了在播放器本身内保持 16:9 的宽高比（HD @1920x1080 的标准宽高比），我们将使用 16/9 和 { 宽度参数调用此函数：40, height:50 }.第二个参数并不关心额外的宽度和高度在内容视图中的位置 - 只关心它们存在。对整个内容视图中的所有额外宽度和高度区域进行求和。
¥Consider a normal window with an HD video player and associated controls. Perhaps there are 15 pixels of controls on the left edge, 25 pixels of controls on the right edge and 50 pixels of controls below the player. In order to maintain a 16:9 aspect ratio (standard aspect ratio for HD @1920x1080) within the player itself we would call this function with arguments of 16/9 and { width: 40, height: 50 }. The second argument doesn't care where the extra width and height are within the content view--only that they exist. Sum any extra width and height areas you have within the overall content view.
当使用 win.setSize 等 API 以编程方式调整窗口大小时，不会考虑宽高比。
¥The aspect ratio is not respected when window is resized programmatically with
APIs like win.setSize.
要重置宽高比，请传递 0 作为 aspectRatio 值：win.setAspectRatio(0)。
