1.20.1 Instance variables

box <- fill: colour|gradient|image|{foreground,background}*

If a colour object is specified, the box is filled using a solid colour. A gradient fills it with a colour transition. An image is repeated to fill the box, starting at the origin of the window or, if box<-fill_offset is not @nil, at that offset from the box. If the initial value @nil is used the box is transparent. The reserved names foreground and background use the current foreground and background colours from the context.

Defaults: @nil (transparent)

box <- fill_offset: point*

If not @nil, the image used as box<-fill starts at this offset from the top-left corner of the box, so that the pattern moves with the box. If @nil, the pattern is aligned to the window.

Defaults: @nil

box <- radius: int

The radius of the circle-fragments used to round the corners. When larger than half the shortest side, this value is used instead of box<->radius. A value of 0 implies square corners.

Defaults: 0 (not rounded)

box <- shadow: 0..|shadow*

Drop shadow painted outside the box. See class shadow. An integer N is a soft shadow N pixels to the bottom right; 0 is no shadow. The default is @nil (no shadow).
