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".
