Glue, HGlue, VGlue - open space between interactors


#include <InterViews/glue.h>


A glue object is an interactor that is used to define variable-size space between interactors in boxes. The HGlue subclass is for space in a horizontal box; VGlue for space in a vertical box. Along its minor axis (vertical for HGlue, horizontal for VGlue), glue has a natural size of zero and infinite stretchability.


HGlue(int natural = 0, int stretch = hfil)
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.
HGlue(int natural, int shrink, int stretch)
VGlue(int natural, int shrink, int stretch)
Construct glue with a given natural size, shrinkability, and stretchability. If shrink is larger than natural the glue potentially can have ``negative size'', meaning interactors will overlap in a box.
