Tk_GetJoinStyle(interp, string, joinPtr)
const char *
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
- Tcl_Interp *interp (in)
Interpreter to use for error reporting.
- const char *string (in)
String containing name of join style - one of
- or a unique abbreviation of one.
- int *joinPtr (out)
Pointer to location in which to store X join style corresponding to
- int join (in)
Join style: one of JoinBevel, JoinMiter, JoinRound.
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”
bevel, join style, miter, round
