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
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.
