XmTextGetSource — A Text function that accesses the source of the widget "XmTextGetSource" "Text

XmTextGetSource accesses the source of the Text widget. Text widgets can share sources of  text  so  that
       editing in one widget is reflected in another. This function accesses the source of one widget so that it
       can be made the source of another widget, using the function XmTextSetSource(3).

       Setting  a  new  text source destroys the old text source if no other Text widgets are using that source.
       To replace a text source but keep it for later use, create an unmanaged Text widget and set its source to
       the text source you want to keep.

       widget    Specifies the Text widget ID

       For a complete definition of Text and its associated resources, see XmText(3).
