Set or return the FieldColor for a screenfield (ScreenField class)
The Color sets or returns the FieldColor for a ScreenField. The FieldColor enumeration provides the color value.
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 (see below) to get sField's current color. |
|---|---|
| sfield | A reference to an instance of a ScreenField object. |
| newFieldcolor | A FieldColor enumeration (see below) setting the color for the sField. |
FieldColor enumeration
The valid values (case unimportant) of this enumeration are turquoise, green, blue, red, white, yellow and pink. The default is blue.
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.
Examples
- For an example using Color method calls, see "Screen Object Sample Code".

- Default field colors may be set by the ProtectedColor or UnprotectedColor properties.
