egroupware/phpgwapi/js/htmlarea/htmlarea.js
viniciuscb 0a28f3812e Some changes:
- Inclusion of the following javascript directories:
  * Connector: javascript object to interface xmlhttprequest object. This object allows
      asynchronous posts and support for messages while this post is being done, such as
      "wait, contacting server", etc.
  * JsAPI: general javascript functions and methods
  * jsolait: performs conversion from a xmlrpc message to a javascript object
  * xmlRpcMsgCreator: performs conversion from a javascript object to a xmlrpc message
  * dynapi: cross-browser class to draw layers

- Update in setup version: now is 1.0.1.008; Update your versions. There was made a
  change in phpgw_vfs2_files table in handling of modified files.

- Upgrade of vfs2 classes and PclZip class

- Changes in javascript object and common object to allow the javascript backend to
  applications to work (now just filescenter will use it...)

*
* Example on how to add a custom button when you construct the HTMLArea:
*
* var editor = new HTMLArea("your_text_area_id");
* var cfg = editor.config; // this is the default configuration
* cfg.btnList["my-hilite"] =
* [ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action
* "Highlight selection", // tooltip
* "my_hilite.gif", // image
* false // disabled in text mode
* ];
* cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
*
* An alternate (also more convenient and recommended) way to
* accomplish this is to use the registerButton function below.
