Description

The DEFINE PAD command defines the pad name <expC1> for the menu name <expC2> for Xbase style menus. The command SET COMPATIBLE should be set ON when using Xbase style menus. The menu name must first be defined with the DEFINE MENU command.

PROMPT <expC3>

The PROMPT <expC3> is displayed inside the menu option, placing a blank space to each side of the prompt when it is displayed.

AT <expN1>,<expN2>

The optional AT coordinates position the pad at row <expN1> and column <expN2> on the screen. If the AT coordinates are not supplied, the pads start in the upper left corner of the screen and place one space in between each prompt.

COLOR <color code> | COLOR SCHEME <color scheme>

The optional COLOR or COLOR SCHEME clause will display the pad in the colors defined by the <color code> foreground/background color pair or the numeric <color scheme>. For more information about color settings, please see the SET COLOR and SET COLOR OF SCHEME commands.

KEY <key label> [,<expC4>]

The optional KEY clause allows the pad to be chosen using the specified <key label>. For more information on key labels, please see the ON KEY LABEL command. If <expC4> is included, this character expression will be displayed instead of the default key label.

MESSAGE <expC5>

The optional MESSAGE clause displays <expC4> in the message line when the cursor is placed on the pad.

SKIP [FOR <expL>]

The SKIP clause allows a particular pad or to be disabled. If the optional FOR <expL> clause is included, the <expL> is evaluated. If the evaluation results in .T. (true) the pad is disabled, if .F. (false), the pad is enabled. If the FOR <expL> clause is not included, the pad is enabled.
