TCB Applications

This program is a work in progress.

TCB does not have any standard look or feel. Certain aspects of TCB can be controlled by a file, tcbinit.txt, that can specify things such as background graphic. Programs can ignore tcbinit by including the switch, iggall=, in the program specification.

TCB only shows what the designer wishes to show. Everything you will see in a TCB window was put there by someone for some reason. Most of the TCB programs in this distribution use a chromeless window style. This refers to a windows style without a title bar or menu bar. All controls are found in the program window.

These windows can be moved by placing the cursor in the window where no other object appears and dragging. The TCB designer can prevent this movement with the moveit= switch.

This tcbapps program window has the usual "About" button and screen control buttons seen in many TCB programs in this distribution. The tcbapps program window displays buttons that will run selected TCB programs. To the right of each program button is a graphic button that will display a screen clip of the selected program window.

Note: there are two primary runtime modules tcb.exe and xmenu.exe. Why 2 run-times? xmenu.exe has only four tangible objects besides the program window. It is a fraction of the size of tcb.exe. It is designed for security and for minimalist applications.

More than 12 different tangible objects can be defined in a tcb.exe program window. tcb.exe also contains prototyping and communications functions not available in xmenu. Up to 399 instances of an object can be defined in a TCB program window.

In all current TCB distributions, TCB programs with a .prc extension should be used with the tcb.exe run-time. TCB programs with a .mnu extension should be run with xmenu.exe.
