NAME
Tk_GetCapStyle, Tk_NameOfCapStyle - translate between strings and cap
styles
SYNOPSIS
#include <tk.h>
int
Tk_GetCapStyle(interp, string, capPtr)
const char *
Tk_NameOfCapStyle(cap)
ARGUMENTS
Interpreter to use for error reporting. String containing name of cap
style: one of or Pointer to location in which to store X cap style cor-
responding to string. Cap style: one of CapButt, CapProjecting, or
CapRound.
DESCRIPTION
Tk_GetCapStyle places in *capPtr the X cap style corresponding to
string. This will be one of the values CapButt, CapProjecting, or
CapRound. Cap styles are typically used in X graphics contexts to
indicate how the end-points of lines should be capped. See the X docu-
mentation 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 cap style or an abbrevia-
tion of one of these names, then an error message is stored in
interp->result, TCL_ERROR is returned, and *capPtr is unmodified.
Tk_NameOfCapStyle is the logical inverse of Tk_GetCapStyle. Given a
cap style such as CapButt it returns a statically-allocated string cor-
responding to cap. If cap is not a legal cap style, then is returned.
KEYWORDS
butt, cap style, projecting, round
