\bold{Preface}
This document presents the Concepts and Facilities of the \bold{Suite}
class.
This class provides interactive views that can be employed to display
visuals
known as \italic{Buttons}, \italic{Lists}, \italic{Catalogs},
\italic{Dialogs}, etc. Although these uses differ in certain
characteristics
(viz, various display techniques), their format and substance are
sufficiently
similar to permit a single Inset to satisfy their diverse needs.
The \bold{Suite} class is a sub-class of the \italic{aptv class} (see
the\italic{ Apt Programming Guide} for details regarding built-in
Iconification, Help, and other common features). The class provides a
View-object (\bold{\sans{suite}}) -- it supports the standard View
operations,
such as FullUpdate, ReceiveInputFocus, Update, etc. As a generic class,
it is
meant to be used by client-programs to provide a variety of interactive
visual
interfaces to suites of items.

\bold{Introduction}
The Suite class provides highly tailorable 2-dimensional layouts of items
that
may be presented visually as suites of Buttons or Lists. The distinction
between Buttons and Lists is nominal: both may be formatted across
multiple
Rows and Columns; both may be scrolled; both may be Titled; etc.
A Suite is a view drawn in the rectangle specified by the client-program
in
the normal ATK -- viz, through \sans{InsertView}.

Client-program interaction via the Suite Title and Items is provided via

the
manner in which the user interacts with the Suite.

\chapter{1 Concepts}
The \bold{suite} class supports interactive views upon \italic{Suites} of
zero
or more \italic{Items}. The Suite visual is an optionally bordered
rectangle;
this area is termed the \italic{Container}. Suite Items are arranged
within
the Container in various fashions, as specified by the Client-program.

You can set various attributes to tailor the manner in which a Suite and
its
Items are displayed and manipulated. Note, however, that all have
defaults
that should yield acceptable formatting. You should begin with the
defaults,
and subsequently try experimenting with the attributes.

(See the section \italic{Samples} for additional Suite visuals.)
The simplest way to use the Suite class is through statically declared
attributes. All that is needed is the set of \italic{Items} to be
displayed
and the name of a\italic{ procedure} to be invoked whenever the User
selects
an Item. Beyond this simple -- and often adequate -- style of usage, you
can
control all the display and interaction attributes through various
\italic{specifications}. You can also generate and modify the Suite and
its
Items \italic{dynamically}, to deal with special considerations found in
your
program: all the Suite and Item attributes can be set or queried through
attribute-access facilities.

By way of example, the following is a complete program
(\italic{\sans{suitex1a}}) employing the Suite class. Its functionality
is
rather simple: it prints the name of the flavor clicked.
\sans{\leftindent{#include
"im.ih"
#include
"suite.ih"
#include
"suitex1a.eh"
struct view
*Flavor_Choice();
char
*list []
=
\{ "Vanilla","Strawberry","Chocolate",
"Grape","Fudge", "Licorice",
"Caramel","Lemon","Orange", NULL \};
suite_Specification
flavors[] =
\{ suite_HitHandler( Flavor_Choice ),
suite_ItemCaptionList ( list ),
NULL
\};
boolean
suitex1app__Start( self )
struct suitex1app
*self;
\{
im_SetView( im_Create(NULL), suite_Create( flavors, self ) );
return TRUE;
\}
void
Flavor_Choice( self, suite, item, type, action, x, y, clicks )
struct suitex1app
*self;
register struct suite
*suite;
register struct suite_item
*item;
\{
printf( "Chosen Flavor is %s\\n",
suite_ItemAttribute( suite, item, suite_ItemCaption(0) ) );
\}
}}
The class-header file for this example is
--
\sans{\leftindent{class suitex1app [suitex1a]: application [app]
\{
overrides:
Start()
returns boolean;
\};}}
Attributes are discussed in the sections \italic{Suite Attributes} and
\italic{Item Attributes}. Other sections detail usage of interactive
programming through \italic{Handlers}, procedures that react to User
selection
of one or more Items.
\section{1.1
Features}
The Suite class provides numerous featrues to support many differnent
visual
effects.
\subsection{1.1.1 Arrangements}
Suite may be arranged in numerous fashions, as specified via the
\sans{suite_Arrangement} attribute.
Given the Items \italic{Alpha},\italic{ Beta},\italic{ Gamma},\italic{
Delta},
and\italic{ Epsilon}, various arrangements would be:

\subsection{1.1.2 Scrolling}
A suite of Items that cannot be fully displayed in the given viewrectangle,
that also enjoys the \sans{Scroll} attribute (which see), will present
subsets
of Items in sequence within each display-frame. Thus, given the 26 Items
"AAAAA", "BBBBB", ..., "ZZZZZ", the following displays result as the User
scrolls forward from the beginning to the end of the suite (assuming a
viewing
width and height sufficient to display only 3 columns and 4 rows).

In the instance of \sans{List} displays that require scrolling of
multiple
columns, you might wish to use \sans{RowMajor}, to provide the common
textual
scrolling phenomenon; although \sans{ColumnMajor} is often more visually
desirable, its scrolling is "snake-wise", from column to column.

\section{1.2
Attribute Specification}
The fashion in which Suites are displayed, as well as the nature and
format of
its Items, is governed by the Specification argument optionally provided
when
the Suite object is created. (See the \sans{Create} facility, discussed
in
the chapter \italic{Facilities -- Object Instantiation.})
The syntax of a specification is best shown through an example This
Suite is
produced through the following specification (\sans{suitex2a}):
\center{\typewriter{
*****************************************
*
Control Buttons
*
*
*
*
Start
Stop
Continue
*
*
*
*****************************************
}}:\sans{\indent{
char
*controls[ ] =
\{
"Start",
"Stop",
suite_Specification
\{
"Continue",
my_buttons[ ] =
NULL
\};
suite_Arrangement( suite_Row ),
suite_BorderSize( 3 ),
suite_TitleCaption( "Control Buttons" ),
suite_TitleCaptionFontName( "AndySans16b" ),
suite_ItemCaptionList( controls ),
suite_ItemCaptionFontName( "Andy12i ),
NULL
\};}}
A Specification is composed of macros, each requiring an argument. The
argument is sometimes a \italic{symbolic} (eg, \sans{suite_Row}),
sometimes a
\italic{numeric value} (eg, the value 3 in \sans{suite_BorderSize}),
sometimes
a \italic{character-string} (eg, the quoted characters \italic{Control
Buttons}
in \sans{suite_TitleCaption}), sometimes a \italic{pointer} to a
null-terminated vector of pointers (eg, the \sans{controls} pointer in
\sans{suite_ItemCaptionList}), sometimes a \italic{pointer} to an Item
Specification, and sometimes a \italic{procedure-pointer}. Note that all
symbolics are prefixed with \sans{ "suite_" } to avoid name-clashes
within the
Client-program. There is no required ordering amongst the items in the
Specification structure; however, it is parsed \italic{sequentially},
such
that subsequent attributes override any earlier conflicting attributes.
See chapter \italic{Sample Programs} for more complete examples.
\subsection{1.2.1 Suite Attributes}
This section lists those attributes that are applicable to the Suite as a
whole, including those Item attributes that are inherited by all Items,
unless
overridden for individual Items. (Attributes are listed\italic{
alphabetically}, for ease of reference.)
\bold{\sans{suite_AccessMode}}
\indent{The Items of a Suite are by default \sans{ReadOnly}. They may be
specified as \sans{ReadWrite}, to support dialogs with the User.
\indent{\sans{suite_ReadOnly}
\sans{suite_ReadWrite
suite_Proceed}}
User interaction via a \sans{ReadWrite} Item is discussed in the section,
\italic{ReadWrite Item Interaction}. The \sans{AccessMode} of individual
Items can be set via the \sans{ItemAccessMode} attribute.}
\sans{\bold{suite_Arrangement}}
\indent{The Suite can be displayed in a variety of arrangements. Certain
attributes are appropriate for displays of \italic{Buttons}, others for
displays of \italic{Lists}.
\indent{\sans{suite_Matrix
\sans{suite_Balanced
|
|
}\sans{suite_Row
|
}\sans{suite_Column}
}\sans{suite_UnBalanced}
\sans{suite_List}
\sans{suite_RowLine}
\sans{suite_ColumnLine}}
The \sans{Column} and \sans{Row} attributes constrain the Items to a
single
Column or Row, respectively. The default attribute (\sans{Matrix})
arranges
Items into one or more rows and columns.
The \sans{Balanced} attribute arranges \italic{matrixed} Items
symmetrically
within the Container; \sans{UnBalanced} leaves the last row or column
possibly
with fewer Items than the other rows and columns.
The \sans{List} attribute arranges Items in one or more columns; Items
are
vertically positioned in terms of the line-height of their font.
\sans{RowLine} and \sans{ColumnLine} cause horizontal or vertical lines,
respectively, to be drawn between Items.
A typical \italic{Button} display would use the default attributes
\sans{Matrix} and \sans{Balanced}. A simple one-column \italic{List}
display
would specify \sans{Column} and \sans{List}; balancing is then
irrelevant. A
multi-column List display would likely use the \sans{List} and
\sans{UnBalanced} attributes, to ensure that the leftmost columns are
each
filled, while the rightmost column shows the remaining Items at its top.
}
\bold{\sans{suite_BorderStyle}}
\indent{The Container may be bordered; by default, the border is a
\sans{Rectangle}, whose line-size is one pixel. It's style may be
specified
in various other fashions:
\indent{
\sans{suite_Rectangle}
\sans{suite_Roundangle}
\sans{suite_Circle}
\sans{suite_Oval}
\sans{suite_Invisible}
\sans{suite_None}}}
\bold{\sans{suite_BorderSize}}
\indent{Where the \sans{BorderStyle} is other than \sans{None}, the
pixel-width of the line may be specified (default is one).}
\bold{\sans{suite_Cursor}}
\indent{The cursor for the entire Suite may be specified as an ASCII
character
literal. If the \sans{CursorFontName} is not specified, the default font
is
\italic{icon12}. The NULL character is reserved.
Example:
\sans{suite_Cursor( 'E' )}}
\bold{\sans{suite_CursorFontName}}
\indent{The font for the Suite's cursor may be specified.
font is
\italic{icon12}.
Example:
The default
\sans{suite_CursorFontName( "myicon20" )}}
\bold{\sans{suite_CursorType}}
\indent{The cursor for the entire Suite may be specified as a standard
symbolic name. The font employed is \italic{icon12}. The default cursor
is
the standard Arrow (\sans{Cursor_Arrow}).
Example:
\sans{suite_CursorType( Cursor_Gunsight )}}
\bold{\sans{suite_Datum}}
\indent{Any Client-program datum (eg, a scalar or a pointer to a
Client-program defined structure). Dynamically accessible via the
\sans{SetSuiteAttribute} and \sans{SuiteAttribute} facilities. (Also see
the
\sans{ItemDatum }attribute, which provides the Item-specific datum
attribute.)}
\sans{\bold{suite_FontName}}
\indent{The default font for all captions (title captions as well) may be
specified. Otherwise, the default font is that specified via the
preference
for "bodyfont"; in the absence of any specification, the built-in default
is a
10-point, fixed-width typewriter font. }
\sans{\bold{suite_GutterSize}}
\indent{Items are separated from one another, vertically and
horizontally, by
the size of the Gutter, which defaults to 1 pixel.}
\bold{\sans{suite_HitHandler}}
\indent{A Suite may specify a Client-program procedure to be invoked
whenever
any area within the Container is hit; this general HitHandler may be
overridden for particular Items via the \sans{ItemHitHandler} attribute
specified for such Items. (See the section \italic{HitHandlers}.)}
\sans{\bold{suite_HorizontalGutterSize}}
\indent{Items are separated from one another horizontally by the size of
the
\sans{HorizontalGutter}, which defaults to 1 pixel.}
\bold{\sans{suite_Item}}
\indent{Identifies an \italic{Item Specification}: a separate structure
in
which an individual Item is specified. This scheme is used where the
\sans{ItemCaptionList} (which see) item is not suitable. Any number of
\sans{Item} entries may appear in the Specification for the Suite.}
\bold{\sans{suite_ItemAccessMode}}
\indent{An Item is by default \sans{ReadOnly}. It may be specified as
\sans{ReadWrite}, to support dialogs with the User.
\indent{\sans{suite_ReadOnly}
\sans{suite_ReadWrite
suite_Proceed}}
User interaction via a \sans{ReadWrite} Item is discussed in the section,
\italic{ReadWrite Item Interaction}.}
\bold{\sans{suite_ItemBorderStyle}}
\indent{Items may be styled with or without Borders; by default, the
border is
a \sans{Rectangle}, whose line-width is one. Borders may be one of the
styles:
\indent{\sans{suite_Rectangle}
\sans{suite_Roundangle}
\sans{suite_Circle}
\sans{suite_Oval}
\sans{suite_Invisible}
\sans{suite_None}}
The Item Border-style \sans{Invisible} may be used in conjunction with
the
Item Highlight-style \sans{Border}: when the Item is highlighted its
border
becomes \italic{visible}; when Normalized, it is \italic{invisible}.
Note
that where the \sans{List} attribute is specified, this attribute is
ignored.
(\sans{Invisible} is used for \sans{List} displays.)}
\bold{\sans{suite_ItemBorderSize}}
\indent{Where the \sans{ItemBorderStyle} is other than \sans{None}, the
pixel-width of the line may be specified (default is one pixel).}
\bold{\sans{suite_ItemCaption}}
\indent{A character-string. All Items will contain this \sans{Caption},
unless overridden by captions or insets assigned to particular items.
(See
\sans{ItemCaptionList} and other attributes.)}
\bold{\sans{suite_ItemCaptionAlignment}}
\indent{The Item's Caption may be aligned at any of nine points within of
the
Item area:
\indent{\sans{suite_Top}
\sans{suite_Bottom}
\sans{suite_Left}
\sans{suite_Right}
\sans{suite_Center}
\sans{suite_Middle}}
These alignments may be combined to effect alignment at any of 9 points.
The
\sans{Center} and \sans{Middle} alignments refer, respectively, to
horizontal
and vertical positioning. By default, Captions are balanced both
horizontally
and vertically: ie, they enjoy the attribute combination
\sans{suite_Center |
suite_Middle}.
Example: \sans{ suite_ItemCaptionAlignment( suite_Bottom | suite_Right)}}
\bold{\sans{suite_ItemCaptionList}}
\indent{Identifies a null-terminated vector of Caption pointers;
\sans{Item} attribute.}
see the
\bold{\sans{suite_ItemCaptionFontName}}
\indent{Where the Items employ the \italic{caption} feature, the Font of
the
captions may be specified; all Items use the same font. Lacking such a
specification, an Item's caption font is the same as the Suite's
\italic{TitleFontName}, but two point-sizes smaller. Lacking a
\sans{TitleCaptionFontName} specification, the default font is that
specified
via the preference for "bodyfont"; in the absence of any specification,
the
built-in default is a 10-point, fixed-width typewriter font.
(The name
is
formatted in the usual fashion -- eg, "andysans12bi", "andy18", etc).
Example:
\sans{suite_ItemCaptionFontName( "andysans10b" )}}
\bold{\sans{suite_ItemCursor}}
\indent{The cursor for individual Items may be specified as an ASCII
character
literal. If the \sans{CursorFontName} is not specified, the default font
is
\italic{icon12}. The NULL character is reserved.
Example:
\sans{suite_ItemCursor( 'E' )}}
\bold{\sans{suite_ItemCursorFontName}}
\indent{The font for the Item's cursor may be specified.
font is
\italic{icon12}.
Example:
The default
\sans{suite_ItemCursorFontName( " myicons16" )}}
\bold{\sans{suite_ItemCursorType}}
\indent{The cursor for individual Items may be specified as a standard
symbolic name. The font employed is \italic{icon12}. The default cursor
is
the standard Arrow (\sans{Cursor_Arrow}).
Example:
\sans{suite_ItemCursorType( Cursor_Gunsight )}}
\bold{\sans{suite_ItemDatum}}
\indent{Any Client-program datum -- eg, a scalar or a pointer to a
client-program defined structure. Dynamically accessible via the
\sans{SetItemAttribute} and \sans{ItemAttribute} facilities. (Also see
the
\sans{Datum} attribute, which provides the Suite datum attribute.)}
\bold{\sans{suite_ItemDataObject}}
\indent{Instead of a Caption, any ATK inset can be specified as the
substance
of a Item. The object is given via an \italic{object-identifier} (ie, a
pointer). (See also \sans{suite_ItemViewObject}.)}
\bold{\sans{suite_ItemDataObjectName}}
\indent{Instead of a Caption, any ATK inset can be specified as the
substance
of an Item. The object name is given as a \italic{character-string}.
(See
also \sans{suite_ItemViewObjectName}.)}
\bold{\sans{suite_ItemDataObjectHandler}}
\indent{A procedure-name may be specified to be associated with the
Item's
Data-object. That procedure is invoked upon instantiation of the
object.}
\bold{\sans{suite_ItemHeight}
\sans{suite_ItemWidth}}
\indent{The width and height of each Item is normally calculated
automatically. However, those calculations may be overridden by these
attributes; one or both may be specified, the omitted attribute being
automatically calculated. (Use of the \sans{List} attribute will cause
these
attributes to be ignored.) The width and height values are in pixels.}
\bold{\sans{suite_ItemHighlightStyle}}
\indent{Items may be highlighted, either upon User selection or through
Client-program request. The styles for Highlighting, which may be used
in
combination, are:
\indent{\sans{suite_Invert}
\sans{suite_Border}
\sans{suite_Bold}
\sans{suite_Italic}}
The \sans{Border} Highlight-style is used in conjunction with the Item
Border-style \sans{Invisible}: when the Item is highlighted its border
becomes
\italic{visible}; when Normalized, it is \italic{invisible}. To combine
several styles, the syntax is --
\sans{suite_ItemHighlightStyle( suite_Bold | suite_Italic)}}
\bold{\sans{suite_ItemHitHandler}}
\indent{An Item may specify the name of a Client-program procedure to be
invoked whenever the Item is the object of a mouse-action. (See the
section
\italic{HitHandlers}.)}
\bold{\sans{suite_ItemName}}
\indent{An Item may be given a \italic{symbolic name} for use during
execution. (See the facilities \sans{ItemOfName} and
\sans{ItemsOfName}.)}
\bold{\sans{suite_ItemOrder}}
\indent{Items are displayed either in \sans{RowMajor} or
\sans{ColumnMajor}
order; the default is \sans{ColumnMajor} -- the fashion used in telephone
directories.}
\bold{\sans{suite_ItemPassiveStyle}}
\indent{An Item can be made passive or active (default is active). An
\italic{active} Item can be selected, a \italic{passive} Item cannot.
The
visual indication of the passive state is controlled by this attribute.
\indent{\sans{suite_Pale}
\sans{suite_Hidden}
\sans{suite_Removed}}
An item is made \sans{Pale} by shading. \sans{Hidden} simply blanks out
the
area within and including the Item border; where an Item is
\sans{Removed},
the Suite is redrawn without the Item.}
\sans{\bold{suite_ItemPosition}}
\indent{The position of the Item within the Suite. The first Item is at
Position 1 (\italic{not} 0). This attribute can be changed dynamically,
resulting in repositioning of Items amongst themselves. For example, an
Item
currently at position 23 can be repositioned to be the fourth Item by
setting
its \sans{ItemPosition} attribute to 4; the Item that had been the
fourth
Item becomes the fifth, etc.}
\bold{\sans{suite_ItemTitleBorderStyle}}
\indent{The ItemTitle may be bordered; by default, the border is
\sans{None}.
Its style may instead be specified in other fashions:
\indent{\sans{suite_None}
\sans{suite_Rectangle}
\sans{suite_Roundangle}
\sans{suite_Circle}
\sans{suite_Oval}
\sans{suite_Invisible}
\sans{suite_Line}}
Instead of a Border, the Item Title can be separated from the Item
Caption by
a single line. The Item Title Border-style \sans{Invisible} is used in
conjunction with the Item Title Highlight-style \sans{Border}: when the
Item
Title is highlighted its border becomes \italic{visible}; when
Normalized, it
is \italic{invisible}.}
\bold{\sans{suite_ItemTitleBorderSize}}
\indent{Where the \sans{ItemTitleBorderStyle} is other than \sans{None},
the
pixel-width of the line (default is one) may be specified.}
\bold{\sans{suite_ItemTitleCaption}}
\indent{An Item may contain a caption as a Title. By default, the Title
is
centered at the top of the Item, beneath the Item's Border. This
Placement
and its Alignment within the title-area can be overridden via the
\sans{ItemTitlePlacement} and \sans{ItemTitleCaptionAlignment}
attributes.
(An Item Title may instead be an Inset.)}
\bold{\sans{suite_ItemTitleCaptionAlignment}}
\indent{The Item's Title caption may be aligned at any of nine points
within
the Item's title area:
\indent{\sans{suite_Top}
\sans{suite_Bottom}
\sans{suite_Left}
\sans{suite_Right}
\sans{suite_Center}
\sans{suite_Middle}}
These alignments may be combined to effect alignment at any of 9 points.
The
\sans{Center} and \sans{Middle} alignments refer, respectively, to
horizontal
and vertical positioning. By default, alignment is \italic{balanced}:
ie,
\sans{suite_Center | suite_Middle}.
Example: \sans{ suite_ItemTitleCaptionAlignment( suite_Bottom |
suite_Right)}}
\bold{\sans{suite_ItemTitleCaptionFontName}}
\indent{Given a Title that is a caption (ie, not an Inset), its font may
be
specified. By default, the font is that specified via the preference for
"bodyfont"}
\sans{ }\bold{\sans{suite_ItemTitleDataObject}}
\indent{Instead of a caption, any ATK \italic{inset} can be specified as
the
substance of a Item Title. The data-object can be specified via an
\italic{object-identifier} (ie, a pointer).}
\sans{ }\bold{\sans{suite_ItemTitleDataObjectName}}
\indent{Instead of a caption, any ATK \italic{inset} can be specified as
the
substance of a Item Title. The data-object name is a
\italic{character-string}: the object is instantiated automatically.}
\bold{\sans{suite_ItemTitleDataObjectHandler}}
\indent{A \sans{procedure} may be specified to be associated with the
Item
Title Data-object. That procedure is invoked upon instantiation of the
object.}
\bold{\sans{suite_ItemTitleHighlightStyle}}
\indent{Item Titles may be highlighted, either upon User selection or
through
Client-program request. The styles for Highlighting, which may be used
in
combination, are:
\indent{\sans{suite_Invert}

\sans{suite_Italic}}
To combine several styles, the syntax is -\sans{suite_ItemTitleHighlightStyle( suite_Bold | suite_Italic)}}
\bold{\sans{suite_ItemTitlePlacement}}
\indent{The Item's Title may be placed at any one of these areas within
the
Item area:
\indent{\sans{suite_Top}
\sans{suite_Bottom}
\sans{suite_Left}
\sans{suite_Right}}}
\sans{ }\bold{\sans{suite_ItemTitleViewObject}}
\indent{Instead of a caption, any ATK \italic{inset} can be specified as
the
substance of a Item Title. The view-object can be specified via an
\italic{object-identifier} (ie, a pointer).}
\sans{ }\bold{\sans{suite_ItemTitleViewObjectName}}
\indent{Instead of a caption, any ATK \italic{inset} can be specified as
the
substance of a Item Title. The view-object name is a
\italic{character-string}: the object is instantiated automatically.}
\bold{\sans{suite_ItemTitleViewObjectHandler}}
\indent{A \sans{procedure} may be specified to be associated with the
Item
Title View-object. That procedure is invoked upon instantiation of the
object.}
\bold{\sans{suite_ItemViewObject}}
\indent{Where a Data-object is specified for an Item, an associated
View-object may be specified; in the absence of a specified
\sans{ViewObject},
the default name implied by the \sans{DataObject} will be employed (as
defined

\bold{\sans{suite_ItemViewObjectName}}
\indent{Where a Data-object is specified for an Item, an associated

\bold{\sans{suite_ItemViewObjectHandler}}
\indent{A procedure-name may be specified to be associated with the
View-object. That procedure is invoked upon instantiation of the

\bold{\sans{suite_Scroll}}
\indent{A Suite may contain more Items than can fit within its Container

dimensions,
of individual Items). Where the \sans{Scroll} attribute is specified,
and if
and only if an overflow condition exists, the specified ScrollBar(s),
will be
displayed -- per the options:
\indent{\sans{suite_Left}
\sans{suite_Right}
\sans{suite_Bottom}
\sans{suite_Top}}
When both vertical and horizontal ScrollBars are specified, the Items are
arranged, by default, with a column-count equal to the row-count. Where
the
\sans{Scroll} attribute is not taken and an overflow condition occurs,
the
overflowing Items are forced to fit in the available space. Multiple
ScrollBars are specified by combining these attribute values, as shown in
the
Example.
Example:

\bold{\sans{suite_SelectionMode}}
\indent{A Suite is either \sans{Exclusive}\sans{, Inclusive, or}
\sans{Toggle.}
An \italic{Exclusive} Suite, the default, allows only a single Item to
be
selected at any moment (initially, no Items are selected). An
\italic{Inclusive} Suite allows zero or more Items to be selected at any
moment. A \italic{Toggle} Suite allows zero or more Items to be selected
at
any moment, each Item selected and deselected individually. (See
section,
\italic{HitHandler}, regarding use of either the Suite's HitHandler or
\italic{each} Item's HitHandler when an \italic{Inclusive} Suite is
multiply-selected.)
Selection of Items within an \italic{Inclusive Suite} may be effected by
the
User "dragging" or "sweeping" the mouse across multiple Items, or by use
of
the Right-button to select non-contiguous Items. These rules apply:
\sans{\italic{LeftDown}}
\indent{Selected Item Highlighted, others Normalized.}
\sans{\italic{LeftMovement}}
\indent{Contiguous Items are Highlighted.}
\sans{\italic{LeftUp}}
\indent{Selection ceases.}
\sans{\italic{RightDown}}
\sans{\italic{RightMovement}}
\indent{Iff Item is Highlighted, it is Normalized;
iff Normal, it is Highlighted.}
\sans{\italic{RightUp}}
\indent{Selection ceases.}
Selection of an Item within an \italic{Exclusive Suite} causes the
previously
selected Item (if any) to be Normalized, and the selected Item to be
Highlighted upon the LeftDown action; however, should the User then drag
the
mouse such that the LeftUp action occurs on another Item, that other Item
is
the one selected and Highlighted.
For an Exclusive Suite, actions of
the
Right-button are the same as for the Left-button.
Selection of an Item within a \italic{Toggle Suite} does not affect
previously
selected Items (if any). The individually selected Item is toggled on or
off,
depending upon its current state; toggling is effected only when the
LeftDown
action occurs. When toggled on, an Item is Highlighted; when toggled
off, the
Item is Normalized.
For a Toggle Suite, actions of the Right-button are
the
same as for the Left-button.

\subsection{1.2.2 Item Attributes}
Each Item can be individually specified. Such specification may be as
minimal
as just its Caption or as elaborate as necessary to individualize each
Item.
Item attributes are inherited from the Suite specification, except where
an
attribute is overridden for that Item via an Item Specification. The
attributes that may appear in a Item Specification are those defined
above,
\italic{Suite Attributes}. Note that either generic or Item-specific
spellings may be employed; thus, to specify the name of an Item's
Caption-font, either \sans{suite_FontName} or
\sans{suite_ItemCaptionFontName} may be used within an Item
specification.
\section{1.3
Handlers}
Whereas the suite class provides appropriate housekeeeping to reflect
User
interaction with a Suite through its view, it is the Client-program's
Handlers
(also known as "call-back procedures") that effect whatever functionality
such
interaction implies. There are various interactions and events that will
cause a Handler to be invoked.
A Handler may be specified for the Suite as a whole or for individual
Items.
In the absence of individual Item Handlers, the Suite Handler is
employed.
Where both a Suite Handler and Item Handlers are specified, the latter
are
employed.
There are three kinds of Handlers: those that cope with Hits, those
dealing
with ReadWrite Item actions, and those that deal with Items, Titles, etc,
specified as Objects (ie, not simply Captions).
\subsection{1.3.1 Hit Handlers}
Upon invocation, a Hit Handler is passed these arguments:
\indent{
\bold{Argument-1:}
The Client-program Anchor associated with the Suite (as provided via the
\sans{suite_Create} facility).
\bold{Argument-2:}
Identifier of the Suite.
\bold{Argument-3:}
Identifier of the object hit.
\bold{Argument 4:}
Hit-object type (\sans{suite_TitleObject}, \sans{suite_ItemObject}, or
Null).
\bold{Arguments 5-8: }
Standard ATK Mouse information -- action, x, y, clicks.}
Thus, a typical Hit Handler would be written:
\indent{\sans{My_Hit_Handler( self, suite, object, type, action, x, y,
clicks
)}}
(The parameter \sans{self} is the value specified as the \italic{Anchor}
by
the Client-program via \sans{suite_Create}.)
All mouse-actions are passed through.
In the instance of an \italic{Inclusive} Suite, the complete set of
currently
selected Items can be obtained through the \sans{suite_SelectedItems}
facility.
\subsection{1.3.2 ReadWrite Handlers}
An Item specified with the \sans{AccessMode} of \sans{ReadWrite} supports
interactive dialogs between the Client program and the User. The User
selects
the Item by clicking into it with the left mouse button, and then types
zero
or more characters; the Enter-key terminates the input-sequence. The
Client
program's Hit Handler is invoked twice: first upon the initial click, and
then
when the Enter-key is depressed. At the initial click, the Client
program may
elect either to leave the Item's current caption or inset as is, clear
it, or
replace it with a new value. When the Enter-key is depressed, the Client
program may extract the caption as a plain-text character-string.
Should the User click outside an Item before the Enter-key is depressed,
the
Entry-key action is synthesized: the Hit Handler is entered for the
second
time.
The Client-program can cause automatic movement (selection) from one
ReadWrite
Item to another via the \sans{Proceed} attribute. When the User
completes the
entry of one Item's value (by depressing the Enter-key), the next
\sans{ReadWrite} Item is automatically selected; when the last such Item
is
completed, selection loops back to the initial \sans{ReadWrite} Item.
\subsection{1.3.3 Object Handlers}
Handlers may specified to deal with instantiation of Data and View
objects.
...
Upon invocation, an Object Handler is passed these arguments:
\indent{\bold{Argument-1:}
The Anchor associated with the Suite.
\bold{Argument-2:}
Identifier of the Suite.
\bold{Argument 3:}
Identifier of the object.
\bold{Argument 4:}
Object-type (Title or Item).
}
Thus, a typical Object Handler would be written:
\sans{\indent{My_Object_Handler( self, suite, object, type )}}

\chapter{2 Facilities}
Facilities are ClassProcedures, Methods, or MacroMethods provided by a
Class
to facilitate communication between an object and its creator. There are
two
groups of facilities: those for the Suite itself, and those for the
Items of
the Suite.
The facilities are presented in a standard form:

\bold{Syntax Conventions}
To provide examples of their usage, both sample statements and a chapter
of
Sample Programs are listed; these are shown in the syntax of the ATK
\italic{Class} extension.
Of particular interest are certain implications upon naming-conventions
and
required arguments:
\indent{
o The ATK Class feature requires methods to be prefixed with the name of
the
Class to which they belong. Further, it requires that the first argument
always be the Identifier (handle or pointer) of the instantiated Object
being
invoked. Thus --
\sans{\bold{\indent{suite_ChangeSuiteAttribute( \italic{object},
suite_TitleCaption( \italic{caption} ) );}}}
\indent{
where :
\sans{\bold{object }}
is the Identifier of the instance of the Class (as returned from the
\sans{suite_Create} facility);
\sans{\bold{caption}}
is a pointer to a character-string.}
o All symbolic-names (eg, those of the options and exception-codes) are
prefixed with the character "suite_" to preclude name-clashes with
Client-program names.}
\section{2.1
Object Instantiation}
The Suite object is instantiated via the \sans{suite_Create} facility.

object is a sub-class of aptv, which is itself a sub-class of the View

\bold{Discussion}\block{
The \sans{Create} facility establishes a
Suite object
through an optional Suite Specification. This \sans{specification}
argument
is a pointer to a vector of symbolics, values, or pointers to values.
Such
vectors are specified within the Client program through special suite
macros,
such as \sans{suite_BorderStyle}, \sans{suite_HitHandler}, etc.
(See
section \italic{Suite Specifications}; also chapter \italic{Sample
Programs}
for illustrations.) The \sans{anchor} argument is usually the
instance-pointer of the object requesting the creation of a Suite object;
this
argument may be NULL.
The vector of \italic{Suite Specifications} is unordered: each item is
self-identifying. Should an item appear more than once, subsequent
appearances override earlier items. However, multiple appearances of the
Item
specification are expected; the sequence in which they appear defines the
initial un-sorted sequence in which the Items will be displayed, unless
changed via a \sans{Sort} attribute.
An \italic{Item Specification} is similarly structured. Note that where
the
\sans{ItemCaptionList} attribute is declared in the Suite specification,
individual \sans{Item} specifications are not allowed; should any appear,
the
AttributeConflict exception is raised and they are ignored. An Item
Specification may contain either a Caption or a DataObject/ViewObject
specification. In the absence of an Item specified \sans{HitHandler}, the
general HitHandler specified in the Suite Specification will be employed;
whether the special or the general HitHandler is employed, the Itemspecified
Datum attribute (which defaults to Null) will be available to the
HitHandler.
The Attribute-Names are symbolics, the Attribute-Values are of the datatype
appropriate to the specific Attribute. The Attributes and associated
Values
are discussed in the \italic{Concepts} chapter.}
\section{2.2
Suite Facilities}
These facilities affect the Suite as a whole.
\subsection{2.2.1 Suite Attributes}
Suite attributes may be set either at compile-time, through the static
declaration of the Specification vector passed as an optional argument
to the
\sans{Create} facility, or dynamically through the \sans{SetAttribute}
facility. In most instances, the static fashion suffices.

Each of the attributes listed in the section
\italic{Suite Specifications} can be set either statically or

suite_SetSuiteAttribute( object, suite_Title( "News of the Day" ) );}
Note that those Attributes that have an impact upon the Suite display do
not
take effect until either the next FullUpdate or Update request is
effected.

Each of the attributes listed in the section
\italic{Item Specifications} can be set either statically or dynamically.
The
syntax for this facility is that employed in the static declaration of
attributes, for example -\sans{\description{suite_ChangeItemAttribute( object, item,
suite_ItemBorderStyle( suite_RoundAngle ) );}
\description{suite_ChangeItemAttribute( object, item, suite_ItemTitle(

\subsection{2.3.2 Item Identification}
Identifiers of individual Items may be obtained through facilities that
scan
the Item set to locate those that matches a given value. These
facilities
need only be employed in those instances that a particular Item is to be
located -- in most instances, such as within \sans{HitHandler}s, you will
find
that the identifier of the Item passed to such procedures suffices.
Some of the identification facilities (eg, \sans{ItemsOfName}) returns a
pointer to a null-terminated vector of Item identifiers; others return a
scalar Item identifier.
Note that where a vector is returned, it exists
only
until the next request for a vectored list is made.
\paragraph{2.3.2.1

\section{2.4
Exception Handling}
All Suite facilities return either a \italic{result-code}, indicating the
success or failure of an operation, or a \italic{function value} such as
an
Item identifier, a scalar, or a pointer. In the former case, you may
test the
result-code for success or failure; in the latter, the Null value is
returned
for exceptional conditions. When an exception is raised, you can use the
Exception facilities to determine its nature.
You may elect to rely upon the default responses to run-time exceptions
or you
may specify a procedure to be invoked whenever such conditions are
detected.
\subsection{2.4.1 SetExceptionHandler}
Sets the given procedure as the ExceptionHandler.
\bold{Synopsis}\block{ \sans{suite_SetExceptionHandler( object, procedure

\sans{object}
Identifier of the Suite object
\sans{item}
Identifier of present Item
\sans{exception

Numeric-code

Where the \sans{item} argument identifies the Item (if any) for which the
exception was raised. The \sans{exception} argument is one of the codes
described in the chapter \italic{Problem Determination}.

This sample differs from the previous in that each Item is individually
specified. By so specifying each Item, the Item's \sans{Datum} attribute
can
be specified.

\chapter{4 Problem Determination}
Compile-time problems are usually merely syntactic difficulties, and
these
would most likely occur in the declaration of a Specification structure
vector. That structure is built up through macros, which expect single
arguments. In particular, be sure to use Null as the last item in the
vector.
Run-time problems can occur at several points:
\indent{When creating the Suite object;
When setting Suite or Item Attributes;
Within HitHandlers.}
All Suite facilities return either an identifier, a scalar, or a Resultcode.
Where a Result-code is returned, it should assist you in tracking down
the
difficulty. Where an identifier or other value is returned, you can
still
access a exception-code that should aid in problem determination. Such a
code, as well as other information, is available through the
\sans{Exception}
facilities; see the section \italic{Exception Handling}.
There is also a built-in tracing feature, used primarily for development.
You
can turn it on and off via the \sans{SetDebug} facility.
