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.
