#electron-vibrancy

This module is intended to give an Electron BrowserWindow blur on its behind. This isnt supported on Electron 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
npm test

To rebuild again:

npm run conf
npm run rebuild

Also available through NPM.

npm install electron-vibrancy

Things to note

• Window must be transparent.
• You can only blur the whole window, therefore only blurring behind a single element isnt possible.
• But it is possible to add individual views using AddView API on macOS.
• If your window has a frame, the frame will also be blurred.
• 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.
• It is known that Dev Tools attached to the window sometimes breaks transparency, it is not related to this module.

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);

  // electronVibrancy.RemoveView(mainWindow,0);
