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. │
|
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). |
_________________________________________________________________
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_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_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.
