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

DESCRIPTION

KEYWORDS

NAME

SYNOPSIS

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” - or a unique abbreviation of one.

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

Under normal circumstances the return value is TCL_OK and interp is unused. If string does not contain a valid join style or an abbreviation of one of these names, then an error message is stored in interpreter interp's 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 is not a legal join style, then “unknown join style” is returned.
