NAME

       Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles

SYNOPSIS

       #include <tk.h>

       int
       Tk_GetJoinStyle(interp, string, joinPtr)

       CONST char *
       Tk_NameOfJoinStyle(join)

ARGUMENTS

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

       CONST char   *string    (in)	 String containing name of join style: one of ``bevel'', ``miter'', or ``round''.

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

       int	    join       (in)	 Join style: one of JoinBevel, JoinMiter, JoinRound.
_________________________________________________________________

DESCRIPTION

       Tk_GetJoinStyle places in *joinPtr the X join style corresponding to string, 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 interp is unused.  If string doesn't contain a valid join style or an abbrevia-
       tion of one of these names, then an error message is stored in interp->result, TCL_ERROR is returned, and *joinPtr 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 join.  If join isn't a legal join style, then ``unknown join style'' is returned.

KEYWORDS

       bevel, join style, miter, round

NAME

       Tk_GetJustifyFromObj, Tk_GetJustify, Tk_NameOfJustify - translate between strings and justification styles

SYNOPSIS

       #include <tk.h>

       int																	   |
       Tk_GetJustifyFromObj(interp, objPtr, justifyPtr) 											   |

       int																	   |
       Tk_GetJustify(interp, string, justifyPtr)												   |

       CONST char *																   |
       Tk_NameOfJustify(justify)														   |

ARGUMENTS
																	   |
       Tcl_Interp   *interp	  (in)														   |
					    Interpreter to use for error reporting, or NULL.							   |

       Tcl_Obj	    *objPtr	  (in/out)													   |
					    String  value contains name of justification style (left, right, or center).  The internal rep will be |
					    modified to cache corresponding justify value.							   |

       CONST char   *string	  (in)														   |
					    Same as objPtr except description of justification style is passed as a string.

       int	    *justifyPtr   (out)     Pointer to location in which to store justify value corresponding to objPtr or string.

       Tk_Justify   justify	  (in)	    Justification style (one of the values listed below).
_________________________________________________________________

DESCRIPTION

       Tk_GetJustifyFromObj places in *justifyPtr the justify value corresponding to objPtr's value.  This value will be one of the following:	   |

       TK_JUSTIFY_LEFT
	      Means that the text on each line should start at the left edge of the line;  as a result, the right edges of lines may be ragged.

       TK_JUSTIFY_RIGHT
	      Means that the text on each line should end at the right edge of the line;  as a result, the left edges of lines may be ragged.

       TK_JUSTIFY_CENTER
	      Means that the text on each line should be centered;  as a result, both the left and right edges of lines may be ragged.

       Under normal circumstances the return value is TCL_OK and interp is unused.  If objPtr doesn't contain a valid justification  style  or	an |
       abbreviation  of one of these names, TCL_ERROR is returned, *justifyPtr is unmodified, and an error message is stored in interp's result if |
       interp isn't NULL.  Tk_GetJustifyFromObj caches information about the return value in objPtr, which speeds up future calls to  Tk_GetJusti- |
       fyFromObj with the same objPtr.														   |

       Tk_GetJustify  is  identical to Tk_GetJustifyFromObj except that the description of the justification is specified with a string instead of |
       an object.  This prevents Tk_GetJustify from caching the return value, so Tk_GetJustify is less efficient than Tk_GetJustifyFromObj.

       Tk_NameOfJustify is the logical inverse of Tk_GetJustify.  Given a justify value it returns a statically-allocated string corresponding	to
       justify.  If justify isn't a legal justify value, then ``unknown justification style'' is returned.

KEYWORDS

       center, fill, justification, string
