Tk_GetJoinStyle, Tk_NameOfJoinStyle — translate between strings and
join styles
#include <tk.h>
int
Tk_GetJoinStyle(interp, string, joinPtr)
const char *
Tk_NameOfJoinStyle(join)
- 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.
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 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.
