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.
