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