BrushVarView, CompNameVarView, FileNameVarView,
FontVarView, GravityVarView, MagnifVarView,
ModifStatusVarView, NameVarView, PatternVarView \- various state
variable view subclasses
.SH SYNOPSIS
.B #include <Unidraw/stateviews.h>
.SH DESCRIPTION
Unidraw predefines several state variable view subclasses for the the
state variable subjects it predefines, as described below.
.SH PUBLIC OPERATIONS
.TP
.B "BrushVarView(BrushVar*, ColorVar* = nil)"
.ns
.TP
.B "FontVarView(FontVar*, Alignment = Center)"
.ns
.TP
.B "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.
.TP
.B "GravityVarView(GravityVar*, Alignment = Center)"
Displays either ``gravity on'' or a blank, depending on whether the
subject indicates that gravity is on or not.
.TP
.B "MagnifVarView(MagnifVar*, Alignment = Center)"
Displays ``mag \fIx\fPx'', where \fIx\fP is the current modification
factor recorded in the subject.
.TP
.B "ModifStateVarView(ModifStateVar*, Alignment = Center)"
Displays either an asterisk or a blank, depending on whether the
subject records that its component is modified.

.br
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 \fIrelative\fP
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.
