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.
