Tk_GetJustifyFromObj(interp, objPtr, justifyPtr)
Tk_GetJustify(interp, string, justifyPtr)
CONST char *
Tk_GetJustifyFromObj places in *justifyPtr the justify value
corresponding to objPtr's value.
This value will be one of the following:
- 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
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
- 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).
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.
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.
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_GetJustifyFromObj 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_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.
