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.

PUBLICOPERATIONS

BrushVarView(BrushVar*, ColorVar* = nil)
FontVarView(FontVar*, Alignment = Center)
PatternVarView(PatternVar*, ColorVar* = nil)
Views of graphics state state variable subjects. BrushVarViewdisplays 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 thesubject 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 thesubject 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.
