Tk Library Procedures
Tk_GetCapStyle, Tk_NameOfCapStyle - translate between strings and cap styles
Tk_GetCapStyle(interp, string, capPtr)
Tcl_Interp *interp (in)
Interpreter to use for error reporting.
char *string (in)
String containing name of cap style: one of ```butt'', ``projecting'',
int *capPtr (out)
Pointer to location in which to store X cap style corresponding to
int cap (in)
Cap style: one of CapButt, CapProjecting, or CapRound.
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
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.
butt, cap style, projecting, round
