The Final Cut

The Final Cut is a C++ class library and widget toolkit with full mouse support for creating a text-based user interface. The library supports the programmer to develop an application for the text console. It allows the simultaneous handling of multiple text windows on the screen. The C++ class design was inspired by the Qt framework. It provides common controls like dialog boxes, push buttons, check boxes, radio buttons, input lines, list boxes, status bars and so on.

newfont

A graphical text font for X11 and the Linux console.

Virtual terminal

It uses a virtual terminal to print the character via an update method on the screen. The virtual windows are an overlying layer to realizing window movements. The update method transmits only the changes to the virtual terminal or the screen.
