Appendix D – Chromium Embedded Framework (CEF), WebView and Electron

You can use CEF or Electron to make a standalone client, so SparkView client can access local resource directly (clipboard), and override some shortcuts keys reserved by the browser (Ctrl+T/W etc). 
 
 Let Spark View know it can access the clipboard directly by setting directClipAccess: true in appcfg.js. 
 For CEF, you need to enable cef_state_t javascript_access_clipboard. 
 For WebView, please check: https://stackoverflow.com/questions/4200259/tapping-formfield-in-webview-does-not-show-soft-keyboard 
 
 For Electron, you can also use mainWindow.webContents.executeJavaScript('hi5.appcfg.directClipAccess=true') to inject the code.
