egroupware_official/phpgwapi/js/wz_dragdrop/wz_dragdrop.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...)

This DHTML & Drag&Drop Library adds Drag&Drop functionality
to the following types of html-elements:
- images, even if not positioned via layers,
nor via stylesheets or any other kind of "hard-coding"
- relatively and absolutely positioned layers (DIV elements).
Moreover, it provides extended DHTML abilities.

/* my_PickFunc IS AUTOMATICALLY CALLED WHEN AN ITEM STARTS TO BE DRAGGED.
The following objects/properties are accessible from here:
- dd.e: current mouse event
- dd.e.property: access to a property of the current mouse event.
Mostly requested properties:
- dd.e.x: document-related x co-ordinate
- dd.e.y: document-related y co-ord
- dd.e.src: target of mouse event (not identical with the drag drop object itself).
- dd.e.button: currently pressed mouse button. Left button: dd.e.button <= 1
- dd.obj: reference to currently dragged item.
- dd.obj.property: access to any property of that item.
- dd.obj.method(): for example dd.obj.resizeTo() or dd.obj.swapImage() .
Mostly requested properties:
- dd.obj.name: image name or layer ID passed to SET_DHTML();
- dd.obj.x and dd.obj.y: co-ordinates;
- dd.obj.w and dd.obj.h: size;
- dd.obj.is_dragged: 1 while item is dragged, else 0;
- dd.obj.is_resized: 1 while item is resized, i.e. if <ctrl> or <shift> is pressed, else 0
