Graphic LineDraw

 CONFIG GRAPHIC_LINEDRAW {ON | RAISED | SUNKEN | OFF}

The Graphic_LineDraw BRConfig.sys specification controls the appearance of borders around windows.

The Problem

Older programs often used GRAPHIC_LINEDRAW and ASCII linedraw characters to create borders. However, if these programs are run in updated versions of BR with CONFIG GUI ON and a wide screen, the character appear as dashes instead of smooth lines.

Instead of this (which can be captured by resizing the screen to the "right" size:

The Solution

To solve this, either run the program with CONFIG GUI OFF, or download the following image files to solve the problem: DRAWLINE.BMP and/or DRAWSUNK.BMP.

Overview

The following linedraw modes are supported:

CONFIG GRAPHIC_LINEDRAW THINRAISED  (Thin line Windows mode)
CONFIG GRAPHIC_LINEDRAW THIN        (Default BR thin line sunken)

CONFIG GRAPHIC_LINEDRAW RAISED   (BR linedraw as before)
CONFIG GRAPHIC_LINEDRAW SUNKEN

RAISED is the default and is synonymous with ON.

SUNKEN, or THIN indents line draw characters giving a bit more conservative appearance.

Lines are drawn on a window by using PRINT FIELDS and linedraw characters. Linedraw characters are generated via the numeric keypad using the numbers 0-9 and . when you are in linedraw mode. To toggle linedraw mode on and off, press Ctrl backslash (CTRL \). See diagram for clarification:

Custom linedraw sets may be used by modifying the bitmaps DRAWLINE.BMP and DRAWSUNK.BMP.

This feature is supported by the CONFIG command and becomes effective upon the next OPEN of window #0. Using EXECUTE allows you to set it from within the program.

Example

Below is a sample program for printing these borders:

Remember to press CTRL\ to type in the linedraw images.
