窗口定制
¥Window customization
BrowserWindow 类公开了修改应用窗口的外观和行为的各种方法。更多详细信息，请参阅 窗口定制 教程。
¥The BrowserWindow class exposes various ways to modify the look and behavior of
your app's windows. For more details, see the Window Customization
tutorial.
优雅地展现窗外
¥Showing the window gracefully
当直接在窗口中加载页面时，用户可能会看到页面逐渐加载，这对于原生应用来说不是一个好的体验。为了使窗口显示没有视觉闪烁，针对不同情况有两种解决方案。
¥When loading a page in the window directly, users may see the page load incrementally, which is not a good experience for a native app. To make the window display without a visual flash, there are two solutions for different situations.
使用 ready-to-show 事件
¥Using the ready-to-show event
加载页面时，如果窗口尚未显示，渲染器进程第一次渲染页面时将发出 ready-to-show 事件。在此事件之后显示窗口将不会出现视觉闪烁：
¥While loading the page, the ready-to-show event will be emitted when the renderer
process has rendered the page for the first time if the window has not been shown yet. Showing
the window after this event will have no visual flash:
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ show: false })
win.once('ready-to-show', () => {
win.show()
})
该事件通常在 did-finish-load 事件之后发出，但对于具有许多远程资源的页面，它可能在 did-finish-load 事件之前发出。
¥This event is usually emitted after the did-finish-load event, but for
pages with many remote resources, it may be emitted before the did-finish-load
event.
请注意，使用此事件意味着渲染器将被视为 "visible" 并进行绘制，即使 show 为 false。如果你使用 paintWhenInitiallyHidden: false，此事件将永远不会触发
¥Please note that using this event implies that the renderer will be considered "visible" and
paint even though show is false. This event will never fire if you use paintWhenInitiallyHidden: false
设置 backgroundColor 属性
¥Setting the backgroundColor property
对于复杂的应用，ready-to-show 事件可能发出得太晚，使应用感觉很慢。在这种情况下，建议立即显示窗口，并使用靠近应用背景的 backgroundColor：
¥For a complex app, the ready-to-show event could be emitted too late, making
the app feel slow. In this case, it is recommended to show the window
immediately, and use a backgroundColor close to your app's background:
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ backgroundColor: '#2e2c29' })
win.loadURL('https://github.com')
请注意，即使对于使用 ready-to-show 事件的应用，仍然建议设置 backgroundColor 以使应用感觉更原生。
¥Note that even for apps that use ready-to-show event, it is still recommended
to set backgroundColor to make the app feel more native.
有效 backgroundColor 值的一些示例包括：
¥Some examples of valid backgroundColor values include:
const win = new BrowserWindow()
win.setBackgroundColor('hsl(230, 100%, 50%)')
win.setBackgroundColor('rgb(255, 145, 145)')
win.setBackgroundColor('#ff00a3')
win.setBackgroundColor('blueviolet')
有关这些颜色类型的更多信息，请参阅 win.setBackgroundColor 中的有效选项。
¥For more information about these color types see valid options in win.setBackgroundColor.
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 { BrowserWindow } = require('electron')
const top = new BrowserWindow()
const child = new BrowserWindow({ parent: top })
child.show()
top.show()
child 窗口将始终显示在 top 窗口的顶部。
¥The child window will always show on top of the top 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 { BrowserWindow } = require('electron')
const top = new BrowserWindow()
const child = new BrowserWindow({ parent: top, modal: true, show: false })
child.loadURL('https://github.com')
child.once('ready-to-show', () => {
child.show()
})
页面可见性
¥Page visibility
页面可见性 API 的工作原理如下：
¥The Page Visibility API works as follows:
在所有平台上，可见性状态都会跟踪窗口是否隐藏/最小化。
¥On all platforms, the visibility state tracks whether the window is hidden/minimized or not.
此外，在 macOS 上，可见性状态还跟踪窗口遮挡状态。如果窗口被另一个窗口遮挡（即完全覆盖），则可见性状态将为
hidden。在其他平台上，仅当窗口最小化或使用win.hide()显式隐藏时，可见性状态才会为hidden。¥Additionally, on macOS, the visibility state also tracks the window occlusion state. If the window is occluded (i.e. fully covered) by another window, the visibility state will be
hidden. On other platforms, the visibility state will behiddenonly when the window is minimized or explicitly hidden withwin.hide().如果使用
show: false创建BrowserWindow，则尽管窗口实际上处于隐藏状态，但初始可见性状态将为visible。¥If a
BrowserWindowis created withshow: false, the initial visibility state will bevisibledespite the window actually being hidden.如果禁用
backgroundThrottling，则即使窗口最小化、遮挡或隐藏，可见性状态也将保持visible。¥If
backgroundThrottlingis disabled, the visibility state will remainvisibleeven if the window is minimized, occluded, or hidden.
建议你在可见性状态为 hidden 时暂停昂贵的操作，以最大程度地减少功耗。
¥It is recommended that you pause expensive operations when the visibility
state is hidden in order to minimize power consumption.
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.

实例事件
¥Instance Events
使用 new BrowserWindow 创建的对象会发出以下事件：
¥Objects created with new BrowserWindow 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：'page-title-updated'
¥Event: 'page-title-updated'
返回：
¥Returns:
event事件¥
eventEventtitle字符串¥
titlestringexplicitSet布尔值¥
explicitSetboolean
当文档更改其标题时发出，调用 event.preventDefault() 将阻止原生窗口的标题更改。当标题是从文件 URL 合成时，explicitSet 为 false。
¥Emitted when the document changed its title, calling event.preventDefault()
will prevent the native window's title from changing.
explicitSet is false when title is synthesized from file URL.
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'

当网页已渲染（但未显示）并且窗口可以在没有视觉闪烁的情况下显示时发出。
¥Emitted when the web page has been rendered (while not being shown) and window can be displayed without a visual flash.
请注意，使用此事件意味着渲染器将被视为 "visible" 并进行绘制，即使 show 为 false。如果你使用 paintWhenInitiallyHidden: false，此事件将永远不会触发
¥Please note that using this event implies that the renderer will be considered "visible" and
paint even though show is false. This event will never fire if you use paintWhenInitiallyHidden: false

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.

¥Returns boolean - Whether the window is minimized.
win.setFullScreen(flag)
flag布尔值¥
flagboolean
设置窗口是否应处于全屏模式。
¥Sets whether the window should be in fullscreen mode.
注意：在 macOS 上，全屏转换是异步发生的。如果进一步的操作取决于全屏状态，请使用 'enter-full-screen' 或 'leave-full-screen' 事件。
¥Note: On macOS, fullscreen transitions take place asynchronously. If further actions depend on the fullscreen state, use the 'enter-full-screen' or 'leave-full-screen' events.
win.isFullScreen()

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)。
¥To reset an aspect ratio, pass 0 as the aspectRatio value: win.setAspectRatio(0).

HSL
hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)例如 HSL(200, 20%, 50%)
¥e.g. hsl(200, 20%, 50%)
HSLA
hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)例如 高斯拉(200, 20%, 50%, 0.5)
¥e.g. hsla(200, 20%, 50%, 0.5)
颜色名称
¥Color name
选项列于 SkParseColor.cpp 中
¥Options are listed in SkParseColor.cpp
与 CSS Color Module Level 3 关键字类似，但区分大小写。

// set all bounds properties
win.setBounds({ x: 440, y: 225, width: 800, height: 600 })
// set a single bounds property
win.setBounds({ width: 100 })
// { x: 440, y: 225, width: 100, height: 600 }
console.log(win.getBounds())
注意：在 macOS 上，y 坐标值不能小于 Tray 高度。托盘高度随着时间的推移而变化，并且取决于操作系统，但在 20-40px 之间。传递低于托盘高度的值将导致窗口与托盘齐平。
¥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()
返回 Rectangle - 窗口的 bounds 为 Object。
¥Returns Rectangle - The bounds of the window as Object.
注意：在 macOS 上，返回的 y 坐标值至少为 Tray 高度。例如，调用托盘高度为 38 的 win.setBounds({ x: 25, y: 20, width: 800, height: 600 }) 意味着 win.getBounds() 将返回 { x: 25, y: 38, width: 800, height: 600 }。
¥Note: On macOS, the y-coordinate value returned will be at minimum the Tray height. For example, calling win.setBounds({ x: 25, y: 20, width: 800, height: 600 }) with a tray height of 38 means that win.getBounds() will return { x: 25, y: 38, width: 800, height: 600 }.
win.getBackgroundColor()
返回 string - 获取十六进制 (#RRGGBB) 格式的窗口背景颜色。
¥Returns string - Gets the background color of the window in Hex (#RRGGBB) format.

win.getNormalBounds()
返回 Rectangle - 包含正常状态的窗口边界
¥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，此函数始终返回正常状态下窗口的位置和大小。在正常状态下，getBounds 和 getNormalBounds 返回相同的 Rectangle。
¥Note: whatever the current state of the window : maximized, minimized or in fullscreen, this function always returns the position and size of the window in normal state. In normal state, getBounds and getNormalBounds returns the same Rectangle.
