BaseWindow
Create and control windows.
Process: Main
Note
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.
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://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 })
Ventana principal y ventana secundaria
By using parent option, you can create child windows:
const { BaseWindow } = require('electron')
const parent = new BaseWindow()
const child = new BaseWindow({ parent })
The child window will always show on top of the parent window.
Ventanas modales
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 })
Notas según la plataforma
- En macOS las ventanas modales se mostrarán como hojas adjuntas a la ventana principal.
- 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.
- On Linux the type of modal windows will be changed to
dialog. - En Linux, muchos entornos de escritorio no admiten ocultar una ventana modal.
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.
Class: BaseWindow
Create and control windows.
Process: Main
BaseWindow is an EventEmitter.
It creates a new BaseWindow with native properties as set by the options.
new BaseWindow([options])
Eventos de Instancia
Objects created with new BaseWindow emit the following events:
Note: Some events are only available on specific operating systems and are labeled as such.
Evento: "close"
Devuelve:
eventEvent
Aparece cuando la ventana se va a cerrar. 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. Por ejemplo:
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.
Evento: "closed"
Emitted when the window is closed. Después de haber recibido este evento, debe eliminar la referencia a la ventana y evitar volverla a usar.
Event: 'session-end' Windows
Aparece cuando la sesión de la ventana va a terminarse debido a un cierre forzoso o el reinicio de la máquina o el cierre de la sesión.
Evento: "blur"
Devuelve:
eventEvent
Aparece cuando la ventana pierde el enfoque.
Evento: "focus"
Devuelve:
eventEvent
Aparece cuando la ventana recupera el enfoque.
Evento: "show"
Aparece cuando se muestra la ventana.
Evento: "hide"
Aparece cuando se oculta la ventana.
Evento: "maximize"
Aparece cuando se maximiza la ventana.
Evento: "unmaximize"
Aparece cuando la ventana sale de un estado maximizado.
Evento: "minimize"
Aparece cuando se minimiza la ventana.
Evento: "restore"
Aparece cuando se restaura la ventana de un estado minimizado.
Event: 'will-resize' macOS Windows
Devuelve:
eventEventnewBoundsRectangle - Size the window is being resized to.detailsObjectedge(string) - The edge of the window being dragged for resizing. Can bebottom,left,right,top-left,top-right,bottom-leftorbottom-right.
Emitido antes de que la ventana sea redimensionada. Calling event.preventDefault() will prevent the window from being resized.
Tenga en cuenta que esto solo es emitido cuando la venta está siendo redimensionada de forma manual. Resizing the window with setBounds/setSize will not emit this event.
The possible values and behaviors of the edge option are platform dependent. Los valores posibles son:
- On Windows, possible values are
bottom,top,left,right,top-left,top-right,bottom-left,bottom-right. - On macOS, possible values are
bottomandright.- The value
bottomis used to denote vertical resizing. - The value
rightis used to denote horizontal resizing.
- The value
Evento: "resize"
Emitido después que la ventana se haya redimensionada.
Event: 'resized' macOS Windows
Emitted once when the window has finished being resized.
This is usually emitted when the window has been resized manually. 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
Devuelve:
eventEventnewBoundsRectangle - Location the window is being moved to.
Emitted before the window is moved. On Windows, calling event.preventDefault() will prevent the window from being moved.
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.
Evento: "move"
Aparece cuando la ventana se mueve a una nueva posición.
Event: 'moved' macOS Windows
Aparece solo una vez cuando la ventana se mueve a una nueva posición.
Note: On macOS this event is an alias of move.
Evento: "enter-full-screen"
Aparece cuando la ventana entra en un estado pantalla completa.
Evento: "leave-full-screen"
Aparece cuando la ventana sale del estado pantalla completa.
Evento: 'always-on-top-changed'
Devuelve:
eventEventisAlwaysOnTopboolean
Emitido cuando la ventana es configurada o no configurada para mostrarse siempre en la parte superior de las otras ventanas.
Event: 'app-command' Windows Linux
Devuelve:
eventEventcommandstring
Emitted when an App Command is invoked. Estos están generalmente relacionados a las teclas del teclado o a los comandos del navegador, así como el botón "Back" está en algunos ratones en Windows.
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.
}
})
Los siguientes comandos de aplicación están explícitamente soportados en Linux:
browser-backwardbrowser-forward
Event: 'swipe' macOS
Devuelve:
eventEventdirectionstring
Emitted on 3-finger swipe. Possible directions are up, right, down, left.
El método subyacente a este evento esta construido para manejar el viejo estilo de desplazamiento del trackpad de macOS, donde el contenido de la pantalla no se mueve con el manotazo. 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
Devuelve:
eventEventrotationFloat
Emitido en el gesto de rotación de trackpad. Continuamente emitido hasta que el gesto de rotación se termine. 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. Los valores de rotación en sentido antihorario son positivos, mientras que los valores de rotación en sentido horario son negativos.
Event: 'sheet-begin' macOS
Aparece cuando la ventana abre una hoja.
Event: 'sheet-end' macOS
Aparece cuando la ventana cierra una hoja.
Event: 'new-window-for-tab' macOS
Aparece cuando se hace clic al botón de nueva pestaña nativa.
Event: 'system-context-menu' Windows
Devuelve:
eventEventpointPoint - The screen coordinates the context menu was triggered at
Emitido cuando el menú contextual del sistema es activado en la ventana, esto normalmente solo es activado cuando el usuario hace click derecho en el área que no es del cliente de la ventana. 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)
viewView
Sets the content view of the window.
win.getContentView()
Returns View - The content view of the window.
win.destroy()
Force closing the window, the unload and beforeunload event won't be emitted
for the web page, and close event will also not be emitted
for this window, but it guarantees the closed event will be emitted.
win.close()
Trate de cerrar la ventana. Esto tiene el mismo efecto que un usuario pulsando manualmente el botón cerrar de la ventana. The web page may cancel the close though. See the close event.
win.focus()
Enfoca la ventana.
win.blur()
Elimina el enfoque de la ventana.
win.isFocused()
Returns boolean - Whether the window is focused.

win.isVisible()
Returns boolean - Whether the window is visible to the user in the foreground of the app.
win.isModal()
Returns boolean - Whether current window is a modal window.
win.maximize()
Maximiza la ventana. This will also show (but not focus) the window if it isn't being displayed already.
win.unmaximize()
Sale del estado maximizado de la ventana.
win.isMaximized()
Returns boolean - Whether the window is maximized.
win.minimize()
Minimiza la ventana. On some platforms the minimized window will be shown in the Dock.
win.restore()
Restaura la ventana desde un estado minimizado a su estado previo.
win.isMinimized()
Returns boolean - Whether the window is minimized.
win.setFullScreen(flag)
flagboolean
Establece si la ventana debe estar o no en modo pantalla completa.
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()
Returns boolean - Whether the window is in fullscreen mode.
win.setSimpleFullScreen(flag) macOS
flagboolean
Entra o sale del modo simple de pantalla completa.
Simple fullscreen mode emulates the native fullscreen behavior found in versions of macOS prior to Lion (10.7).
win.isSimpleFullScreen() macOS
Returns boolean - Whether the window is in simple (pre-Lion) fullscreen mode.
win.isNormal()
Returns boolean - Whether the window is in normal state (not maximized, not minimized, not in fullscreen mode).
win.setAspectRatio(aspectRatio[, extraSize])
aspectRatioFloat - The aspect ratio to maintain for some portion of the content view.extraSizeSize (optional) macOS - The extra size not to be included while maintaining the aspect ratio.
Esto hará que la ventana mantenga una relación de aspecto. El tamaño extra permite al desarrollador tener espacio especificado en píxeles, el cual no está incluido dentro de los cálculos de la relación de aspecto. Esta API ya toma en cuenta la diferencia entre el tamaño de la ventana y el tamaño del contenido.
Considere una ventana normal con un reproductor de video HD y los controles asociados. Quizá hay 15 pixeles de controles en el borde izquierdo, 25 pixeles de control en el borde derecho y 50 pixeles de control bajo el reproductor. Para mantener una relación de aspecto 16:9 (relación de aspecto estándar para HD @1920x1080) dentro del reproductor tendríamos que llamar esta función con argumentos de 16/9 y { width: 40, height: 50 . En el segundo argumento no importa donde están la anchura extra ni altura extra dentro de la vista del contenido, solo importa que existan. Suma cualquier áreas de ancho y alto adicionales que tengas dentro de la vista de contenido general.
The aspect ratio is not respected when window is resized programmatically with
APIs like win.setSize.
To reset an aspect ratio, pass 0 as the aspectRatio value: win.setAspectRatio(0).

// set a single bounds property
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.
