/**
|
|
* This class contains logic for getting HTML contents out of the clipboard.
|
|
*
|
|
* We need to make a lot of ugly hacks to get the contents out of the clipboard since
|
|
* the W3C Clipboard API is broken in all browsers: Gecko/WebKit/Blink. We might rewrite
|
|
* this the way those API:s stabilize.
|
|
*
|
|
* Current implementation steps:
|
|
* 1. On keydown with paste keys Ctrl+V or Shift+Insert create
|
|
* a paste bin element and move focus to that element.
|
|
* 2. Wait for the browser to fire a "paste" event and get the contents out of the paste bin.
|
|
* 3. Check if the paste was successful if true, process the HTML.
|
|
* (4). If the paste was unsuccessful use IE execCommand, Clipboard API, document.dataTransfer old WebKit API etc.
