Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles
Tk_GetJoinStyle(interp, string, joinPtr)
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.
- char *string (in)
String containing name of join style: one of ``bevel'', ``miter'',
- 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 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.
