#electron-vibrancy

As of #7898 Vibrancy is now supported in Electron for macOS.

This module is intended to give an Electron BrowserWindow blur on its behind. Electron does not support 'blur behind' from a transparent window and this module uses native API calls to achieve the effect.

Running

Since this is a native addon, you will need your platforms build tools. Visual Studio,XCode etc.Also Python for node-gyp.

git clone https://github.com/arkenthera/electron-vibrancy
cd electron-vibrancy
npm install
cd spec/app # Go to sample app
electron . # electron --version should be 1.6.8

To rebuild again:

npm run conf
npm run rebuild

Also available through NPM.

npm install electron-vibrancy

To run tests see scripts/ci

Current Supported Platforms

• macOS 10.10+
• Windows 10 (stable) It just works ™
• Windows 8.x (unstable + requires modifications)
• Windows 7 (unstable + requires modifications)

Things to note

• BrowserWindow must be transparent. (transparent:true)
• Requires Yosemite on macOS.
• On Windows 8.x, this wont work because Microsoft completely removed Aero Glass feature. It is still possible though but it is not something that an end user should do. See Platforms section for more info.
• On Windows 7, an Aero theme must be activated.
• If you get A dynamic link library (DLL) initialization routine failed. error, it means that the module isn't compiled against Electron or compiled against the wrong version.

Although it works, I dont recommend using this module on a machine below Windows 10. See platforms section below for more information for macOS.

How to use

// Require the module
var electronVibrancy = require('..');
electronVibrancy.SetVibrancy(true,browserWindowInstance.getNativeWindowHandle());


// Preferred Usage

// mainWindow with show: false
mainWindow.on('ready-to-show',function() {
  var electronVibrancy = require('..');
  
  // Whole window vibrancy with Material 0 and auto resize
  electronVibrancy.SetVibrancy(mainWindow, 0);

  // auto resizing vibrant view at {0,0} with size {300,300} with Material 0
  electronVibrancy.AddView(mainWindow, { Width: 300,Height:300,X:0,Y:0,ResizeMask:2,Material:0 })

  // non-resizing vibrant view at {0,0} with size {300,300} with Material 0
  electronVibrancy.AddView(mainWindow, { Width: 300,Height:300,X:0,Y:0,ResizeMask:3,Material:0 })

  //Remove a view
  var viewId = electronVibrancy.SetVibrancy(mainWindow, 0);
  electronVibrancy.RemoveView(mainWindow,viewId);

  // Add a view then update it
  var viewId = electronVibrancy.SetVibrancy(mainWindow, 0);
  electronVibrancy.UpdateView(mainWindow,{ ViewId: viewId,Width: 600, Height: 600 });

  // Multipe views with different materials
  var viewId1 = electronVibrancy.AddView(mainWindow, { Width: 300,Height:300,X:0,Y:0,ResizeMask:3,Material:0 })
  var viewId2 = electronVibrancy.AddView(mainWindow, { Width: 300,Height:300,X:300,Y:0,ResizeMask:3,Material:2 })

  console.log(viewId1);
  console.log(viewId2);

Platform notices

Windows

On Windows 10 the addon uses SetWindowCompositionAttribute, which is an undocumented API, which means it can be changed by Microsoft any time and break the functionality.

MacOS

Requires Yosemite and above.Some materials require 10.11+. Since this is the case, if you use a material that's not available on that macOS version, it will fallback to the default material value which is 0, which might not be what you want.
