NAME

       BrushVarView,     CompNameVarView,     FileNameVarView,    FontVarView,    GravityVarView,
       MagnifVarView, ModifStatusVarView, NameVarView, PatternVarView -  various  state  variable
       view subclasses

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
              BrushVar's  brush  is  invisible.   Similarly,  PatternVarView  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 PatternVar's pattern is invisible.  FontVarView displays  the  name  of  its
              subject's font, aligned as specified in its canvas.

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

       MagnifVarView(MagnifVar*, Alignment = Center)
              Displays ``mag xx'', where x is the current modification  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(
           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 specialized 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.   CompNameVarView  provides  similar  functionality   for   CompNameVar
              subjects,  except it precedes its subject's component's name with ``[part of]'' for
              components that have a named parent but that are not named themselves.
