NAME
Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles
SYNOPSIS
#include <tk.h>
int
Tk_GetJoinStyle(interp, string, joinPtr)
CONST char *
Tk_NameOfJoinStyle(join)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for error reporting.
CONST char *string (in) String containing name of join style: one of ``bevel'', ``miter'',
or ``round''.
int *joinPtr (out) Pointer to location in which to store X join style corresponding to
string.
int join (in) Join style: one of JoinBevel, JoinMiter, JoinRound.
____________________________________________________________________________________________________________
DESCRIPTION
Tk_GetJoinStyle places in *joinPtr the X join style corresponding to string, which will be one of
JoinBevel, JoinMiter, or JoinRound. Join styles are typically used in X graphics contexts to indi-cate indicate
cate how adjacent line segments should be joined together. See the X documentation for information
on what each style implies.
Under normal circumstances the return value is TCL_OK and interp is unused. If string doesn't con-tain contain
tain a valid join style or an abbreviation of one of these names, then an error message is stored in
interp->result, TCL_ERROR is returned, and *joinPtr is unmodified.
Tk_NameOfJoinStyle is the logical inverse of Tk_GetJoinStyle. Given a join style such as JoinBevel
it returns a statically-allocated string corresponding to join. If join isn't a legal join style,
then ``unknown join style'' is returned.
KEYWORDS
