-
- NAME

- strings and join styles
-
- SYNOPSIS
- #include <tk.h>
-
- int
- Tk_GetJoinStyle(_i_n_t_e_r_p, _s_t_r_i_n_g, _j_o_i_n_P_t_r)
-
- char *
- Tk_NameOfJoinStyle(_j_o_i_n)
-
- ARGUMENTS
- Tcl_Interp *_i_n_t_e_r_p (in) Interpreter to use for
- error reporting.
-
- char *_s_t_r_i_n_g (in) String containing name of
- join style: one of
- ``bevel'', ``miter'', or
- ``round''.
-
- int *_j_o_i_n_P_t_r (out) Pointer to location in
- which to store X join
- style corresponding to
- _s_t_r_i_n_g.
-
- int _j_o_i_n (in) Join style: one of Join-
- Bevel, JoinMiter, Join-
- Round.

- DESCRIPTION
- Tk_GetJoinStyle places in *_j_o_i_n_P_t_r the X join style
- corresponding to _s_t_r_i_n_g, 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
- _i_n_t_e_r_p is unused. If _s_t_r_i_n_g doesn't contain a valid join
- style or an abbreviation of one of these names, then an
- error message is stored in _i_n_t_e_r_p->_r_e_s_u_l_t, TCL_ERROR is
- returned, and *_j_o_i_n_P_t_r 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 _j_o_i_n.
