Set or return the highlight attribute for screenfield (ScreenField class)

The Highlight property sets or returns the value of the highlight for a ScreenField. The Highlight enumeration provides the highlight value.

This attribute is initially set for a field by the AddField method.


%currentHighlight = sfield:Highlight sfield:Highlight = newHighlight

Syntax terms

%currentHightlight An enumeration of type Highlight (see below) to get sField's current hightlight.
sfield A reference to an instance of a ScreenField object.
newHightlight An enumeration of type Highlight (see below) setting sField's new hightlight.

Highlight enumeration

Valid values of this enumeration are None, Underline, Reverse, and Blink. The default value is None.

Note: As with all enumerations, the ToString method implicitly converts an enumeration value to a character string whose value is the name of the enumeration value. For more information about methods available to all enumerations, see "Common enumeration methods".

Usage notes

  • Under either of these conditions, which are not detectable by the screen methods, the display may not show the intended colors:
    • Highlight lets you set highlights regardless of the actual terminal type, although some terminals may not display these attributes correctly.
    • Many terminal emulator programs allow local customization of highlighting attributes.


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