XmTabSetValue sets the value field of the XmTab
structure associated with tab.
tab
Specifies the tab to set the value of.
value
Specifies the floating point number which represents the distance that
the rendering of the XmString segment associated with tab
will be offset. The offset is from either the beginning of the
rendering or from the previous tab stop, depending on the setting for
the offset model. The distance depends on the tab's unit type.
Note that negative values are not permitted, and that if a tab stop
would cause text to overlap, the x position for the segment is set
immediately after the end of the previous segment.
