210 // The whole selection thingie in this class is somewhat .... suspicious to me.
211 // some oddities:
212 // * method parameters named like members (and used in both semantics within the method!)
213 // * the multi selection flag is sometimes used as if it is for row selection, sometimes as if
214 //   it's for column selection, too (and sometimes in an even stranger way :)
215 // * it is not really defined like all these hundreds selection related flags/methods work together
216 //   and influence each other. I do not understand it very well, but this may be my fault :)
217 // * There is a GetColumnSelection, but it can't be used to determine the selected columns (at least
218 //   not without a const_cast)
219 //
220 // We should clearly define this somewhere in the future. Or, even better, we should re-implement this
221 // whole class, which is planned for a long time :)
