.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH "BOXES"
.PP
The \fBTtk_Box\fR structure represents a rectangular region of a window:
.CS
typedef struct {
    int \fIx\fR;
    int \fIy\fR;
    int \fIwidth\fR;
    int \fIheight\fR;
} \fBTtk_Box\fR;
.CE
All coordinates are relative to the window.
.PP
\fBTtk_MakeBox\fR is a convenience routine that contsructs
a \fBTtk_Box\fR structure representing a region \fIwidth\fR pixels
wide, \fIheight\fR pixels tall, at the specified \fIx, y\fR coordinates.
.PP
\fBTtk_PadBox\fR returns a new box located inside the specified \fIparcel\fR,
shrunken according to the left, top, right, and bottom margins
specified by \fIpadding\fR.
.PP
\fBTtk_ExpandBox\fR is the inverse of \fBTtk_PadBox\fR:
it returns a new box surrounding the specified \fIparcel\fR,
expanded  according to the left, top, right, and bottom margins
specified by \fIpadding\fR.
.PP
\fBTtk_PackBox\fR allocates a parcel \fIwidth\fR by \fIheight\fR
pixels wide on the specified \fIside\fR of the \fIcavity\fR,
and shrinks the \fIcavity\fR accordingly.
.PP
\fBTtk_StickBox\fR places a box with the requested \fIwidth\fR
and \fIheight\fR inside the \fIparcel\fR according to the
\fIsticky\fR bits.
.PP
\fBTtk_PlaceBox\fR combines \fBTtk_PackBox\fR and \fBTtk_StickBox\fR:
it allocates a parcel on the specified \fIside\fR of the \fIcavity\fR,
places a box of the requested size inside the parcel according to \fIsticky\fR,
and shrinks the \fIcavity\fR.
.PP
\fBTtk_AnchorBox\fR places a box with the requested \fIwidth\fR
and \fIheight\fR inside the \fIparcel\fR according to the
specified \fIanchor\fR option.
.PP
\fBTtk_BoxContains\fR tests if the specified \fIx, y\fR coordinate
lies within the rectangular region \fIbox\fR.
.SH "PADDDING"
.PP
The \fBTtk_Padding\fR structure is used to represent
borders, internal padding, and external margins:
.CS
typedef struct {
    short \fIleft\fR;
    short \fItop\fR;
    short \fIright\fR;
    short \fIbottom\fR;
} \fBTtk_Padding\fR;
.CE
.PP
\fBTtk_MakePadding\fR is a convenience routine that contsructs
a \fBTtk_Padding\fR structure with the specified left, top, right, and bottom
components.
.PP
\fBTtk_UniformPadding\fR constructs a \fBTtk_Padding\fR structure
with all components equal to the specified \fIborder\fR.
.PP
\fBTtk_AddPadding\fR adds two \fBTtk_Padding\fRs together
and returns a combined padding containing the sum of the
individual padding components.
.PP
\fBTtk_RelievePadding\fR 
adds an extra 2 pixels of padding to \fIpadding\fR
according to the specified \fIrelief\fR.
If \fIrelief\fR is \fBTK_RELIEF_SUNKEN\fR, 
adds two pixels at the top and left
so the inner region is shifted down and to the left.
If it is \fBTK_RELIEF_RAISED\fR, adds two pixels
at the bottom and right so 
the inner region is shifted up and to the right.
Otherwise, adds 1 pixel on all sides.
This is typically used in element geometry procedures to simulate a
.QW pressed-in
look for pushbuttons.
.SH "CONVERSION ROUTINES"
.PP
\fBTtk_GetPaddingFromObj\fR converts the string in \fIobjPtr\fR
to a \fBTtk_Padding\fR structure.
The string representation is a list of 
up to four length specifications 
.QW "\fIleft top right bottom\fR" .
If fewer than four elements are specified, 
\fIbottom\fR defaults to \fItop\fR,
\fIright\fR defaults to \fIleft\fR, and 
\fItop\fR defaults to \fIleft\fR.
See \fBTk_GetPixelsFromObj(3)\fR for the syntax of length specifications.
.PP
\fBTtk_GetBorderFromObj\fR is the same as \fBTtk_GetPaddingFromObj\fR
except that the lengths are specified as integers 
(i.e., resolution-dependant values like \fI3m\fR are not allowed).
.PP
\fBTtk_GetStickyFromObj\fR converts the string in \fIobjPtr\fR
to a \fIsticky\fR bitmask.  The string contains zero or more
of the characters \fBn\fR, \fBs\fR, \fBe\fR, or \fBw\fR.
