Overview

The OFCGWT project provides a simple to use chart widget for GWT based on Open Flash Chart 2. The library includes the needed flash insertion, update and manipulation methods for the chart widget. It also includes a POJO model for the chart elements and components that assist in the generation of the JSON to provide the correct chart data for OFC 2.x API.

The project has released a beta of version 2.x and a stable 1.3.x release - with over 12,000+ downloads !!

Note: A beta of v2.0 (GWT 1.6 support) does contain breaking API for those coming from the 1.X version of OFCGWT - it contains new refactored events and a new chart factory, better attach/detach support, new charts features(new Horizontal Stack Bar Chart, enhanced animations based on OFC Ichor with DZ fixes and patches).

Current Status

• 2009-Apr-21: Version 2.0.1 beta released.

Demo

• New Std Demo - Added Transparent Image Bar Chart
• Events Demo - onClick Events Demo showing drill-down

Note: Source code for both demos and more is available in the SVN (click the source tab above and browse to the /trunk/test folder).

[javascript] DropzoneJS - drag'n'drop file uploads with image previews library

http://www.dropzonejs.com/

Github : https://github.com/enyo/dropzone

Installation

Download the standalone dropzone.js and include it like this:

<script src="./path/to/dropzone.js"></script>

Dropzone is now activated and available as window.Dropzone.

Dropzone does not handle your file uploads on the server. You have to implement the code to receive and store the file yourself.

"enyo/dropzone": "*"

var Dropzone = require("dropzone");

<form action="/file-upload"
      class="dropzone"
      id="my-awesome-dropzone"></form>

<input type="file" name="file" />

<form action="/file-upload" class="dropzone">
  <div class="fallback">
    <input name="file" type="file" multiple />
  </div>
</form>
