BaseWindow

创建和控制窗口。

Process: Main

注意 BaseWindow 提供了一种在单个窗口中灵活组合多个web视图的方式。 For windows with only a single, full-size web view, the BrowserWindow class may be a simpler option.

This module cannot be used until the ready event of the app module is emitted.

// 在主进程中
const { BaseWindow, WebContentsView } = require('electron')

const win = new BaseWindow({ width: 800, height: 600 })

const leftView = new WebContentsView()
leftView.webContents.loadURL('https://electronjs.org')
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 })

父子窗口

通过使用 parent 选项，可以创建子窗口:

const { BaseWindow } = require('electron')

const parent = new BaseWindow()
const child = new BaseWindow({ parent })

child子窗口将始终显示在parent父窗口的顶部。

模态窗口

模态窗口是禁用父窗口的子窗口。要创建模态窗口，必须同时设置parent和modal选项：

const { BaseWindow } = require('electron')

const parent = new BaseWindow()
const child = new BaseWindow({ parent, modal: true })

平台相关的提示

在 macOS 上，modal 窗口将显示为附加到父窗口的工作表。
在 macOS 上，当父窗口移动时，子窗口将保持相对位置，而在 Windows 和 Linux 上，子窗口将不会移动。
在 Linux 上，模态窗口的类型将更改为dialog。
在Linux上，许多桌面环境不支持隐藏模态窗口。

Resource management

When you add a WebContentsView to a BaseWindow and the BaseWindow is closed, the webContents of the WebContentsView are not destroyed automatically.

It is your responsibility to close the webContents when you no longer need them, e.g. when the BaseWindow is closed:

const { BaseWindow, WebContentsView } = require('electron')

const win = new BaseWindow({ width: 800, height: 600 })

const view = new WebContentsView()
win.contentView.addChildView(view)

win.on('closed', () => {
  view.webContents.close()
})

Unlike with a BrowserWindow, if you don't explicitly close the webContents, you'll encounter memory leaks.

- visualEffectState string (optional) macOS - Specify how the material appearance should reflect window activity state on macOS. Must be used with the vibrancy property. 可能的值有
  - followWindow - The backdrop should automatically appear active when the window is active, and inactive when it is not. 默认为该值。
  - active - The backdrop should always appear active.
  - inactive - The backdrop should always appear inactive.
- titleBarStyle string (optional) - The style of window title bar. Default is default. 可能的值有
  - default - Results in the standard title bar for macOS or Windows respectively.
  - hidden - Results in a hidden title bar and a full size content window. 在 macOS 内, 窗口将一直拥有位于左上的标准窗口控制器 (“traffic lights”)。 On Windows and Linux, when combined with titleBarOverlay: true it will activate the Window Controls Overlay (see titleBarOverlay for more information), otherwise no window controls will be shown.
  - hiddenInset macOS - Results in a hidden title bar with an alternative look where the traffic light buttons are slightly more inset from the window edge.
  - customButtonsOnHover macOS - Results in a hidden title bar and a full size content window, the traffic light buttons will display when being hovered over in the top left of the window. Note: This option is currently experimental.
- titleBarOverlay Object | Boolean (optional) - When using a frameless window in conjunction with win.setWindowButtonVisibility(true) on macOS or using a titleBarStyle so that the standard window controls ("traffic lights" on macOS) are visible, this property enables the Window Controls Overlay JavaScript APIs and CSS Environment Variables. Specifying true will result in an overlay with default system colors. Default is false.

- thickFrame boolean (optional) - Use WS_THICKFRAME style for frameless windows on Windows, which adds standard window frame. Setting it to false will remove window shadow and window animations. Default is true.
- vibrancy string (optional) macOS - Add a type of vibrancy effect to the window, only on macOS. Can be appearance-based, titlebar, selection, menu, popover, sidebar, header, sheet, window, hud, fullscreen-ui, tooltip, content, under-window, or under-page.
- backgroundMaterial string (optional) Windows - Set the window's system-drawn background material, including behind the non-client area. Can be auto, none, mica, acrylic or tabbed. See win.setBackgroundMaterial for more information.
- zoomToPageWidth boolean (optional) macOS - Controls the behavior on macOS when option-clicking the green stoplight button on the toolbar or by clicking the Window > Zoom menu item. If true, the window will grow to the preferred width of the web page when zoomed, false will cause it to zoom to the width of the screen. This will also affect the behavior when calling maximize() directly. Default is false.
- tabbingIdentifier string (optional) macOS - Tab group name, allows opening the window as a native tab. Windows with the same tabbing identifier will be grouped together. This also adds a native new tab button to your window's tab bar and allows your app and window to receive the new-window-for-tab event.
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 选项的可用值和可能的行为与平台相关。可能的值有
- On Linux, possible types are desktop, dock, toolbar, splash, notification.
  - The desktop type 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.
  - The dock type creates a dock-like window behavior.
  - The toolbar type creates a window with a toolbar appearance.
  - The splash type 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.
  - The notification type creates a window that behaves like a system notification.
- On macOS, possible types are desktop, textured, panel.
  - The textured type adds metal gradient appearance. This option is deprecated.
  - The desktop type 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 use globalShortcut to receive input sparingly.
  - The panel type enables the window to float on top of full-screened apps by adding the NSWindowStyleMaskNonactivatingPanel style mask,normally reserved for NSPanel, at runtime. Also, the window will appear on all spaces (desktops).
- On Windows, possible type is toolbar.

实例事件

Objects created with new BaseWindow emit the following events:

Note: Some events are only available on specific operating systems and are labeled as such.

事件： 'close'

event Event

在窗口要关闭的时候触发。 It's emitted before the beforeunload and unload event of the DOM. Calling event.preventDefault() will cancel the close.

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. 例如：

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
}

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'

在窗口关闭时触发当你接收到这个事件的时候, 你应当移除相应窗口的引用对象，避免再次使用它.

Event: 'session-end' Windows

因为强制关机或机器重启或会话注销而导致窗口会话结束时触发

事件: 'blur'

event Event

当窗口失去焦点时触发

事件: 'focus'

event Event

当窗口获得焦点时触发

事件: 'show'

当窗口显示时触发

事件: 'hide'

当窗口隐藏时触发

事件: 'maximize'

窗口最大化时触发

事件: 'unmaximize'

当窗口从最大化状态退出时触发

事件: 'minimize'

窗口最小化时触发

事件: 'restore'

当窗口从最小化状态恢复时触发

Event: 'will-resize' macOS Windows

event Event
newBounds Rectangle - Size the window is being resized to.
details Object
- edge (string) - The edge of the window being dragged for resizing. Can be bottom, left, right, top-left, top-right, bottom-left or bottom-right.

调整窗口大小前触发。 Calling event.preventDefault() will prevent the window from being resized.

请注意，该事件仅在手动调整窗口大小时触发。 Resizing the window with setBounds/setSize will not emit this event.

The possible values and behaviors of the edge option are platform dependent. 可能的值有

On Windows, possible values are bottom, top, left, right, top-left, top-right, bottom-left, bottom-right.
On macOS, possible values are bottom and right.
- The value bottom is used to denote vertical resizing.
- The value right is used to denote horizontal resizing.

事件: 'resize'

调整窗口大小后触发。

Event: 'resized' macOS Windows

当窗口完成调整大小后触发一次。

这通常在手动调整窗口大小后触发。 On macOS, resizing the window with setBounds/setSize and setting the animate parameter to true will also emit this event once resizing has finished.

Event: 'will-move' macOS Windows

event Event
newBounds Rectangle - Location the window is being moved to.

窗口移动前触发。 On Windows, calling event.preventDefault() will prevent the window from being moved.

注意：仅当手动移动窗口时才会触发此消息。 Moving the window with setPosition/setBounds/center will not emit this event.

事件: 'move'

窗口移动到新位置时触发

Event: 'moved' macOS Windows

当窗口移动到新位置时触发一次

Note: On macOS this event is an alias of move.

事件: 'enter-full-screen'

窗口进入全屏状态时触发

事件: 'leave-full-screen'

窗口离开全屏状态时触发

事件: 'always-on-top-changed'

event Event
isAlwaysOnTop boolean

设置或取消设置窗口总是在其他窗口的顶部显示时触发。

Event: 'app-command' Windows Linux

event Event
command string

Emitted when an App Command is invoked. 典型的是键盘上的媒体键或浏览器命令, 以及在Windows上的一些鼠标中内置的“后退”按钮。

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.
  }
})

以下应用命令在 Linux 上有明确地支持：

browser-backward
browser-forward

Event: 'swipe' macOS

event Event
direction string

三指滑动时触发。 Possible directions are up, right, down, left.

此事件的基本方法是用来处理旧的macOS风格的触摸板滑动，屏幕内容不会随着滑动而移动。 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'.

Event: 'rotate-gesture' macOS

event Event
rotation Float

在触控板旋转手势上触发。持续触发直到旋转手势结束。 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. 逆时针旋转值为正值，顺时针旋转值为负值。

Event: 'sheet-begin' macOS

窗口打开sheet(工作表) 时触发

Event: 'sheet-end' macOS

窗口关闭sheet(工作表) 时触发

Event: 'new-window-for-tab' macOS

当点击了系统的新标签按钮时触发

event Event
point Point - The screen coordinates the context menu was triggered at

当系统上下文菜单在窗口上触发时发出，通常只在用户右键点击你窗口的非客户端区域时触发。 This is the window titlebar or any area you have declared as -webkit-app-region: drag in a frameless window.

Calling event.preventDefault() will prevent the menu from being displayed.

`win.setContentView(view)`

view View

设置窗口的内容视图。

`win.getContentView()`

Returns View - The content view of the window.

`win.destroy()`

强制关闭窗口，不会为网页触发unload和beforeunload事件，也不会为此窗口触发close事件，但保证会触发closed事件。

`win.close()`

尝试关闭窗口。该方法与用户手动单击窗口的关闭按钮效果相同。但网页可能会取消这个关闭操作。参见 close 事件。

`win.focus()`

聚焦于窗口

`win.blur()`

取消窗口的聚焦

`win.isFocused()`

返回boolean - 窗口是否聚焦。

`win.isDestroyed()`

返回boolean - 窗口是否被销毁。

`win.show()`

显示并聚焦于窗口

`win.showInactive()`

显示但不聚焦于窗口

`win.hide()`

隐藏窗口

`win.isVisible()`

返回boolean - 窗口是否在应用程序前台对用户可见。

`win.isModal()`

返回boolean - 当前窗口是否为模态窗口。

`win.maximize()`

最大化窗口。如果窗口尚未显示，该方法也会将其显示 (但不会聚焦)。

`win.unmaximize()`

取消窗口最大化

`win.isMaximized()`

返回boolean - 窗口是否最大化。

`win.minimize()`

最小化窗口。在某些平台上, 最小化的窗口将显示在Dock中。

`win.restore()`

将窗口从最小化状态恢复到以前的状态。

`win.isMinimized()`

返回boolean - 窗口是否最小化。

`win.setFullScreen(flag)`

flag boolean

设置窗口是否应处于全屏模式。

注意：在 macOS 上，全屏转换是异步进行的。 If further actions depend on the fullscreen state, use the 'enter-full-screen' or 'leave-full-screen' events.

`win.isFullScreen()`

返回boolean - 窗口是否处于全屏模式。

`win.setSimpleFullScreen(flag)` macOS

flag boolean

进入或离开简单的全屏模式。

简单全屏模式模拟了 Lion (10.7) 之前的macOS版本中的原生全屏行为。

`win.isSimpleFullScreen()` macOS

返回boolean - 窗口是否处于简单(Lion 之前的) 全屏模式。

`win.isNormal()`

返回boolean - 窗口是否处于正常状态(未最大化，未最小化，未处于全屏模式) 。

`win.setAspectRatio(aspectRatio[, extraSize])`

aspectRatio Float - 要保持的内容视图某部分的宽高比。
extraSize Size (optional) macOS - The extra size not to be included while maintaining the aspect ratio.

这将使窗口保持长宽比。额外的大小允许开发人员有空间 (以像素为单位), 不包括在纵横比计算中。此 API 已经考虑了窗口大小和内容大小之间的差异。

想象一个使用高清视频播放器和相关控件的普通窗口。假假如左边缘有15px, 右边缘有25px, 在播放器下面有50px. 为了在播放器内部保持 16:9 的宽高比(HD @1920x1080 的标准宽高比) ，我们将此函数的参数设置为 16/9 和 { width: 40, height: 50 }。第二个参数不管网页中的额外的宽度和高度在什么位置, 只要它们存在就行. 在全部内部窗口中，加上任何额外的宽度和高度。

当使用win.setSize等 API 以编程方式调整窗口大小时，不会遵循宽高比。

要重置长宽比，请将aspectRatio设置为 0：win.setAspectRatio(0)。

`win.setBackgroundColor(backgroundColor)`

backgroundColor string - 颜色格式为 Hex、RGB、RGBA、HSL、HSLA 或命名的 CSS 颜色。对于 Hex 类型，透明通道为可选的。

有效的backgroundColor值示例：

Hex
- #fff (shorthand RGB)
- #ffff (shorthand ARGB)
- #ffffff (RGB)
- #ffffffff (ARGB)
RGB
- rgb\(([\d]+),\s*([\d]+),\s*([\d]+)\)
  - e.g. rgb(255, 255, 255)
RGBA
- rgba\(([\d]+),\s*([\d]+),\s*([\d]+),\s*([\d.]+)\)
  - e.g. rgba(255, 255, 255, 1.0)
HSL
- hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)
  - e.g. hsl(200, 20%, 50%)
HSLA
- hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)
  - e.g. hsla(200, 20%, 50%, 0.5)
Color name
- Options are listed in SkParseColor.cpp
- 类似 CSS Color Module Level 3 关键字，但大小写敏感。
  - e.g. blueviolet or red

设置窗口的背景颜色。 See Setting backgroundColor.

`win.previewFile(path[, displayName])` macOS

path string - 要使用 QuickLook 预览的文件的绝对路径。这很重要，因为 Quick Look 使用路径上的文件名和文件扩展名来确定要打开的文件类型。
displayName string (可选) - 要在 Quick Look 模态视图中显示的文件名称。这仅是视觉上的，不影响文件的内容类型。默认为 path.

使用 Quick Look 预览给定路径的文件。

`win.closeFilePreview()` macOS

关闭当前打开的 Quick Look 面板。

`win.setBounds(bounds[, animate])`

bounds Partial<Rectangle>
animate boolean (可选) macOS

重置窗口，并且移动窗口到指定的位置. 任何未提供的属性将默认为其当前值。

const { BaseWindow } = require('electron')
const win = new BaseWindow()

// 设置所有边界属性
win.setBounds({ x: 440, y: 225, width: 800, height: 600 })

// 设置单个边界属性
win.setBounds({ width: 100 })

// { x: 440, y: 225, width: 100, height: 600 }
console.log(win.getBounds())

Note: On macOS, the y-coordinate value cannot be smaller than the Tray height. The tray height has changed over time and depends on the operating system, but is between 20-40px. Passing a value lower than the tray height will result in a window that is flush to the tray.

`win.getBounds()`

Returns Rectangle - The bounds of the window as Object.

Note: On macOS, the y-coordinate value returned will be at minimum the Tray height. 例如，使用托盘高度为 38 的情况下调用win.setBounds({ x: 25, y: 20, width: 800, height: 600 })将导致win.getBounds()返回{ x: 25, y: 38, width: 800, height: 600 }。

`win.getBackgroundColor()`

返回string - 以 Hex (#RRGGBB) 格式获取窗口的背景颜色。

See Setting backgroundColor.

注意： Alpha 值不会与红色、绿色和蓝色值一起返回。

`win.setContentBounds(bounds[, animate])`

bounds Rectangle
animate boolean (可选) macOS

调整窗口的工作区 (如网页) 的大小并将其移动到所提供的边界。

`win.getContentBounds()`

Returns Rectangle - The bounds of the window's client area as Object.

`win.getNormalBounds()`

Returns Rectangle - Contains the window bounds of the normal state

注意：无论窗口的当前状态如何：最大化、最小化或全屏，此函数始终返回窗口在正常状态下的位置和大小。 In normal state, getBounds and getNormalBounds returns the same Rectangle.

`win.setEnabled(enable)`

enable boolean

禁用或者启用窗口。

`win.isEnabled()`

返回 boolean - 窗口是否启用。

`win.setSize(width, height[, animate])`

width Integer
height Integer

`win.getSize()`

返回 Integer [] - 包含窗口的宽度和高度。

`win.setContentSize(width, height[, animate])`

width Integer
height Integer
animate boolean (可选) macOS

将窗口的工作区 (如网页) 大小调整为 width 和 height。
