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
