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.
