PureGEM

PureGEM started out as a VCL/LCL style library written in PurePascal. After the system was working, I saw ways to increase the speed while reducing code size, so the design drifted somewhat. Since PurePascal is "Turbo Pascal 7.0 compatible" a number of VCL style features needed to be implemented differently. Namely TNotifyEvent's are replaced with owner recursive methods. RTTI features are implemented via set's. Initially I had planned to use more of the GEM API, but some of the features I wanted required replacing all window elements. This is a new library, so expect code to change. I will be working on this for the next 1-2 years. cheers Derek

QuickCrt

Based upon my 20+ year old super fast QCrt text mode display driver, QuickCrt is an event driven object-oriented framework for rapid application development using Turbo Pascal 7.0 for DOS. Completely self contained, it uses no 3rd party or original Borland units (excluding the built-in System unit). It uses no Turbo Vision and is more like Delphi minus the drag and drop. It has support for String formatting, Custom text fonts, Themes, Keyboard mappings, Config files and Multiple languages baked into it. However, this initial version is more of a "Proof of Concept" and engine for PGME. Rather than an actual project. It has some serious limitations. Since it was built in a "vacuum" with no pre-planning, it is a little bit of spaghetti code. Also, it doesn't support real windowing, multi-tasking or draw behind visible objects. QCrt 9 is currently under development. It is a complete rewrite in assembly with TP wrappers. It is being hosted at http://github.com/LoopZ/QCrt

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.
