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.

KEYWORDS

butt, cap style, projecting, round
