SetCurrentBreakInfo(...) is equivalent to TopLevelEditor.SetBreakInfoEd(TopLevelEditor.CurItemNo, ...).
This method can be used if CurItemStyle returns rvsBreak.
Parameters:
AWidth – line width (or rectangle height). This value is measured in Style.Units.
AStyle – visual style of this break, see TRVBreakStyle for possible values.
AColor – line color. If it is equal to rvclNone, Style.TextStyles[0].Color is used.
ATag – tag of the item. You can use value returned by GetCurrentBreakInfo or GetCurrentTag for this item.
Instead of this method, you can use SetCurrentItemExtraIntPropertyEx and SetCurrentTag methods.
Method type: 
editing-style.
Additional item properties are assigned by the methods SetCurrentItemExtraIntProperty and SetCurrentItemExtraStrProperty.
