Set or return the FieldColor for a screenfield (ScreenField class)

The Color method sets or returns the color value (FieldColor enumeration) of a ScreenField.

Colors may be initially set for a field when it is created by the AddField method.

Syntax

%currentFieldColor = sfield:Color sfield:Color = newFieldColor

Syntax terms

%currentFieldcolor A FieldColor enumeration to get sfield's current color.
sfield A reference to an instance of a ScreenField object.
newFieldcolor A FieldColor enumeration setting the color for the sfield.

Usage notes

  • Under either of these conditions, which are not detectable by the screen methods, the display may not show the intended colors:
    • Color lets you set colors regardless of the actual terminal type, although some terminals may not display these attributes correctly.
    • Many terminal emulator programs allow local customization of color attributes.
  • Default field colors may be set by the ProtectedColor or UnprotectedColor properties.

Examples

For an example using Color method calls, see "Screen object sample code".
