qxotica - tools for qooxdoo

Includes a package for the Lazarus IDE that adds items to the File | New dialog. Selecting "qooxdoo JavaScript App" creates either a single-page or two-page master-detail qooxdoo app and a Lazarus project for managing and editing the app's JavaScript files. Selecting "qooxdoo JavaScript Page" adds a page to the app and to the Lazarus project. Can also "compile" (run generate.py) from within Lazarus - if a syntax error is detected, the code editor jumps to the JavaScript file and line where the error is located. Also includes full source code for the Unicodum demo app. This is a Unicode viewer consisting of a qooxdoo-based mobile client and a choice of Pascal (FCGI) or PHP server app.
