.TH Tk_GetCapStyle 3tk "" Tk "Tk Library Procedures"
.\" 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 NAME
Tk_GetCapStyle, Tk_NameOfCapStyle \- translate between strings and cap styles
.SH SYNOPSIS
.nf
\fB#include <tk.h>\fR
.sp
int
\fBTk_GetCapStyle(\fIinterp, string, capPtr\fB)\fR
.sp
const char *
\fBTk_NameOfCapStyle(\fIcap\fB)\fR
.SH ARGUMENTS
.AS "Tcl_Interp" *capPtr
.AP Tcl_Interp *interp in
Interpreter to use for error reporting.
.AP "const char" *string in
String containing name of cap style: one of
.QW butt ,
.QW projecting ,
or
.QW round .
.AP int *capPtr out
Pointer to location in which to store X cap style corresponding to
\fIstring\fR.
.AP int cap in
Cap style: one of \fBCapButt\fR, \fBCapProjecting\fR, or \fBCapRound\fR.
.BE

.SH DESCRIPTION
.PP
\fBTk_GetCapStyle\fR places in \fI*capPtr\fR the X cap style
corresponding to \fIstring\fR.
This will be one of the values
\fBCapButt\fR, \fBCapProjecting\fR, or \fBCapRound\fR.
Cap styles are typically used in X graphics contexts to indicate
how the end-points of lines should be capped.
See the X documentation for information on what each style
implies.
.PP
Under normal circumstances the return value is \fBTCL_OK\fR and
\fIinterp\fR is unused.
If \fIstring\fR does not contain a valid cap style
or an abbreviation of one of these names, then an error message is
stored in \fIinterp->result\fR, \fBTCL_ERROR\fR is returned, and
\fI*capPtr\fR is unmodified.
.PP
\fBTk_NameOfCapStyle\fR is the logical inverse of \fBTk_GetCapStyle\fR.
Given a cap style such as \fBCapButt\fR it returns a
statically-allocated string corresponding to \fIcap\fR.
If \fIcap\fR is not a legal cap style, then
.QW "unknown cap style"
is returned.
