Tk_GetJoinStyle(3Tk)Tk_GetJoinStyle(3Tk)NAME
Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join
styles
SYNOPSIS
#include <tk.h>
int
Tk_GetJoinStyle(interp, string, joinPtr)
char *
Tk_NameOfJoinStyle(join)ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for error reporting.
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 indicate 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 contain 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
