SYNOPSIS

       #include <Unidraw/stateviews.h>

DESCRIPTION

       Unidraw predefines several state variable view  subclasses
       for  the  the  state  variable  subjects it predefines, as
       described below.

PUBLIC OPERATIONS

       BrushVarView(BrushVar*, ColorVar* = nil)
       FontVarView(FontVar*, Alignment = Center)
       PatternVarView(PatternVar*, ColorVar* = nil)
              Views of graphics state  state  variable  subjects.
              BrushVarView  displays  a  short  line drawn in the
              subject's brush and in a  color  specified  by  the
              given  ColorVar (black if no ColorVar is supplied).
              The BrushVarView displays ``None''  if  the  Brush-
              Var's  brush  is  invisible.   Similarly,  Pattern-
              VarView displays a filled rectangle  drawn  in  the
              subject's  pattern  and in a color specified by the
              given ColorVar (black if no ColorVar is  supplied).
              The  PatternVarView  displays  ``None'' if the Pat-
              ternVar's pattern is invisible.   FontVarView  dis-
              plays  the  name  of its subject's font, aligned as
              specified in its canvas.

       GravityVarView(GravityVar*, Alignment = Center)
              Displays either ``gravity on'' or a blank,  depend-
              ing  on  whether the subject indicates that gravity
              is on or not.

       MagnifVarView(MagnifVar*, Alignment = Center)
              Displays ``mag xx'', where x is the current modifi-
              cation factor recorded in the subject.

       ModifStateVarView(ModifStateVar*, Alignment = Center)
              Displays  either  an asterisk or a blank, depending
              on whether the subject records that  its  component
              is modified.

       NameVarView(
           NameVar*, Alignment = Center, const char* sample = nil
       )

       FileNameVarView(
           NameVar*, Alignment = Center,
           boolean relative = true, const char* sample = nil
           CompNameVarView*, Alignment = Center,
           boolean relative = true, const char* sample = nil
       )
              Display the subject's string aligned  as  specified
              with respect to the canvas.  Each constructor takes
              an optional sample string that defines  the  view's
              natural  size.  FileNameVarView provides a special-
              ized view of a NameVar for displaying  file  names.
              It adds a relative argument for displaying the file
              name either as a  relative  or  full  path.   Comp-
              NameVarView   provides  similar  functionality  for
              CompNameVar subjects, except it precedes  its  sub-
              ject's component's name with ``[part of]'' for com-
              ponents that have a named parent but that  are  not
              named themselves.
