33 :
34 : Left/Right margin and first line indent
35 :
36 : SvxLRSpaceItem offers two interfaces for views from the left margin and
37 : first line indent. The get methods return the member, with the layout also
38 : as expected: the left edge shifts to the negative first line indent to the
39 : left. The SetTxt/Gettxt methods assume that the left side represents the
40 : 0 coordinate for the first line indent:
