NAME

Tk_GetCapStyle, Tk_NameOfCapStyle - translate between strings and cap styles
 

SYNOPSIS

#include <tk.h>

int
Tk_GetCapStyle(interp, string, capPtr)

char *
Tk_NameOfCapStyle(cap)

ARGUMENTS

Tcl_Interp    *interp    (in)
Interpreter to use for error reporting.

char    *string    (in)
String containing name of cap style: one of ```butt'', ``projecting'', or ``round''.

int    *capPtr    (out)
Pointer to location in which to store X cap style corresponding to string.

int    cap    (in)
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 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 cap style or an abbreviation 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 corresponding to cap. If cap isn't a legal cap style, then ``unknown cap style'' is returned.
