LINE DRAWING GRAPHICS


ubmulti, ubprompt and ubmenu all recognise the following conventions for putting line drawing graphics on the screen:

‘-‘ in first coloumn. Draw a line across the screen (ubmulti only).

‘~’ draw a horizontal line.

‘|’ draw a vertical line.

Additionally these programs will adjust the graphics to include corners, tees, crosses, etc as required.

INSTALLATION NOTES


Calendar

UNIBASE includes the open source jscalendar as a popup for date entry fields. The calendar image and popup code is included automatically for any date field.

To make it operational you need to include a link to the jscalendar code in the htm directory of your application.

(as root)
# cd $UG_APP/htm
# ln -s /usr/local/lib/jscalendar-1.0 .

Application Layout

UNIBASE expects applications to have the following directory structure:

  1. All applications are in the directory /usr/local/app. eg /usr/local/app/payroll
  2. dct: the data dictionary files
  3. htm: the web site (symbolically linked to the root directory of the web server as the application name.
    eg ln -s /usr/local/app/payroll/htm /var/www/html/payroll

ubitem

NAME

ubitem – execute a command on selected items

SYNOPSIS

ubitem -[C* E F* H* L Q S d f* g* i k# w*] <item>

DESCRIPTION

ubitem displays a list of text items on a formatted screen. The first item is highlighted and the highlighting can be moved up and down the list by using the arrow keys. The highlighted item can be selected (indicated by a `*’) or deselected by pressing the AB key. Pressing one of the programed FUNCTION KEYS will execute a predetermined script for each item.

F1 (SEARCH) can be used to find an entry by entering a string. EXIT can be used to exit without doing anything.

Pressing RETURN will execute the first defined function key with the currently selected list.

If no items are selected when a function key or RETURN is pressed, the currently highlighted record will be automatically selected.

The list of items to choose from can be a file, output from a unix command, read from standard input, or text values stored in the command file.

Depending on the configuration single or multiple selections may be made.

A selection list consists of lines of text. Each line has one or two parts. A return value and a display value. If there is only one part then it is used for both display and return. The two parts of each line are separated by a ‘:’. This may be changed – see command line options below.

When a script is executed, the return values of the selected items are passed as arguments to the script.

After reading the selection list, ubitem displays some (or all depending on screen size) of the list with the first item highlighted. The user can use the arrow keys to move the highlighting up or down the list. The list will scroll as appropriate.

The format for file, the control file, can be found in item(4).
