The VBTKitEnv interface provides a way to collect in one
place the various environment variables that widgets in the
vbtkit use for controlling their appearance.
INTERFACEVBTKitEnv ;
SCROLLBARLOC specifies where scrollbars should be placed. The
possible values are north, northeast, northwest, south,
southeast, southwest, east, and west. The default location for
a vertical scrollbar is west; and for a horizontal scrollbar, the
default location is south.
VAR (* read-only after initialization *) ScrollbarWest: BOOLEAN := TRUE; ScrollbarSouth: BOOLEAN := TRUE;
TEXTPORTMODEL specifies the editing model that text-editing widgets
should use. The possible values are emacs, ivy, mac, and xterm;
emacs is the default value. See the TextPort interface for more
information.
VAR (* read-only after initialization *) TextPortModel: TEXT := "emacs"; END VBTKitEnv.
