browser-window

The BrowserWindow class gives you ability to create a browser window, an example is:

var BrowserWindow = require('browser-window');

var win = new BrowserWindow({ width: 800, height: 600, show: false });
win.on('closed', function() {
  win = null;
});

win.loadUrl('https://github.com');
win.show();

You can also create a window without chrome by using Frameless Window API.

Class: BrowserWindow

BrowserWindow is an EventEmitter.

new BrowserWindow(options)

• options Object
  • x Integer - Window's left offset to screen
  • y Integer - Window's top offset to screen
  • width Integer - Window's width
  • height Integer - Window's height
  • use-content-size Boolean - The width and height would be used as web page's size, which means the actual window's size will include window frame's size and be slightly larger.
  • center Boolean - Show window in the center of the screen
  • min-width Integer - Minimum width
  • min-height Integer - Minimum height
  • max-width Integer - Maximum width
  • max-height Integer - Maximum height
  • resizable Boolean - Whether window is resizable
  • always-on-top Boolean - Whether the window should always stay on top of other windows
  • fullscreen Boolean - Whether the window should show in fullscreen, when set to false the fullscreen button would also be hidden on OS X
  • skip-taskbar Boolean - Do not show window in taskbar
  • zoom-factor Number - The default zoom factor of the page, zoom factor is zoom percent / 100, so 3.0 represents 300%
  • kiosk Boolean - The kiosk mode
  • title String - Default window title
  • icon NativeImage - The window icon, when omitted on Windows the executable's icon would be used as window icon
  • show Boolean - Whether window should be shown when created
  • frame Boolean - Specify false to create a Frameless Window
  • node-integration Boolean - Whether node integration is enabled, default is true
  • accept-first-mouse Boolean - Whether the web view accepts a single mouse-down event that simultaneously activates the window
  • disable-auto-hide-cursor Boolean - Do not hide cursor when typing
  • auto-hide-menu-bar Boolean - Auto hide the menu bar unless the Alt key is pressed.
  • enable-larger-than-screen Boolean - Enable the window to be resized larger than screen.
  • dark-theme Boolean - Forces using dark theme for the window, only works on some GTK+3 desktop environments
  • preload String - Specifies a script that will be loaded before other scripts run in the window. This script will always have access to node APIs no matter whether node integration is turned on for the window, and the path of preload script has to be absolute path.
  • transparent Boolean - Makes the window transparent
  • type String - Specifies the type of the window, possible types are desktop, dock, toolbar, splash, notification. This only works on Linux.
  • standard-window Boolean - Uses the OS X's standard window instead of the textured window. Defaults to true.

    • plugins Boolean - Whether plugins should be enabled, currently only NPAPI plugins are supported.
    • extra-plugin-dirs Array - Array of paths that would be searched for plugins. Note that if you want to add a directory under your app, you should use __dirname or process.resourcesPath to join the paths to make them absolute, using relative paths would make Electron search under current working directory.
    • experimental-features Boolean
    • experimental-canvas-features Boolean
    • subpixel-font-scaling Boolean
    • overlay-scrollbars Boolean
    • overlay-fullscreen-video Boolean

    • page-visibility Boolean - Page would be forced to be always in visible or hidden state once set, instead of reflecting current window's visibility. Users can set it to true to prevent throttling of DOM timers.

Creates a new BrowserWindow with native properties set by the options. Usually you only need to set the width and height, other properties will have decent default values.

Event: 'page-title-updated'

• event Event

Emitted when the document changed its title, calling event.preventDefault() would prevent the native window's title to change.

Event: 'close'

• event Event

Emitted when the window is going to be closed. It's emitted before the beforeunload and unload event of DOM, calling event.preventDefault() would 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 an empty string or false would cancel the close. An example is:

window.onbeforeunload = function(e) {
  console.log('I do not want to be closed');

  // Unlike usual browsers, in which a string should be returned and the user is
  // prompted to confirm the page unload, Electron gives developers more options.
  // Returning empty string or false would prevent the unloading now.
  // You can also use the dialog API to let the user confirm closing the application.
  return false;
};

Event: 'closed'

Emitted when the window is closed. After you have received this event you should remove the reference to the window and avoid using it anymore.

Event: 'unresponsive'

Event: 'restore'

Emitted when window is restored from minimized state.

Event: 'resize'

Emitted when window is getting resized.

Event: 'move'

Emitted when the window is getting moved to a new position.

Note: On OS X this event is just an alias of moved.

Event: 'moved'

Emitted once when the window is moved to a new position.

Note: This event is available only on OS X.

Event: 'enter-full-screen'

Emitted when window enters full screen state.

Event: 'leave-full-screen'

  • printBackground Boolean - Also prints the background color and image of the web page, defaults to false.

Prints window's web page. When silent is set to false, Electron will pick up system's default printer and default settings for printing.

Calling window.print() in web page is equivalent to call WebContents.print({silent: false, printBackground: false}).

Note: On Windows, the print API relies on pdf.dll. If your application doesn't need print feature, you can safely remove pdf.dll in saving binary size.

WebContents.printToPDF(options, callback)

    • 0 - default
    • 1 - none
    • 2 - minimum

Prints windows' web page as PDF with Chromium's preview printing custom settings.

By default, an empty options will be regarded as {marginsType:0, printBackgrounds:false, printSelectionOnly:false, landscape:false}.

var BrowserWindow = require('browser-window');
var fs = require('fs');

var win = new BrowserWindow({width: 800, height: 600});
win.loadUrl("http://github.com");

win.webContents.on("did-finish-load", function() {
  // Use default printing options
  win.webContents.printToPDF({}, function(error, data) {
    if (error) throw error;
    fs.writeFile(dist, data, function(error) {
      if (err)
        alert('write pdf file error', error);
    })
  })
});

WebContents.send(channel[, args...])

• channel String

Send args.. to the web page via channel in asynchronous message, the web page can handle it by listening to the channel event of ipc module.

An example of sending messages from the main process to the renderer process:

// On the main process.
var window = null;
app.on('ready', function() {
  window = new BrowserWindow({width: 800, height: 600});
  window.loadUrl('file://' + __dirname + '/index.html');
  window.webContents.on('did-finish-load', function() {
    window.webContents.send('ping', 'whoooooooh!');
  });
});

// index.html
<html>
<body>
  <script>
    require('ipc').on('ping', function(message) {
      console.log(message);  // Prints "whoooooooh!"
    });
  </script>
</body>
</html>

Note:

1. The IPC message handler in web pages do not have a event parameter, which is different from the handlers on the main process.
2. There is no way to send synchronous messages from the main process to a renderer process, because it would be very easy to cause dead locks.
