.SH NAME
Glue, HGlue, VGlue \- open space between interactors
.SH SYNOPSIS
.B #include <InterViews/glue.h>
.SH DESCRIPTION
A glue object is an interactor that is used to define
variable-size space between interactors in boxes.
The \fBHGlue\fP subclass is for space in a horizontal box;
\fBVGlue\fP for space in a vertical box.
Along its minor axis (vertical for \fBHGlue\fP, horizontal for \fBVGlue\fP),
glue has a natural size of zero and infinite stretchability.
.SH PUBLIC OPERATIONS
.TP
.B "HGlue(int natural = 0, int stretch = hfil)"
.ns
.TP
.B "VGlue(int natural = 0, int stretch = vfil)"
Construct glue with a given natural size and stretchability.
The glue's shrinkability is defined to be the same as the natural size,
meaning it can shrink to zero.
.TP
.B "HGlue(int natural, int shrink, int stretch)"
.ns
.TP
.B "VGlue(int natural, int shrink, int stretch)"
Construct glue with a given natural size,
shrinkability, and stretchability.
If \fIshrink\fP is larger than \fInatural\fP
the glue potentially can have ``negative size'', meaning
interactors will overlap in a box.
