This class must not derive from the native wxDatePickerCtrl, as it doesn't make much sense and resulted in the need for an ugly hack with either overriding unused and inapplicable pure virtual methods in this class itself, as was originally done in569c7d8ccb(Add wxTimePickerCtrl class., 2011-09-29) when it was introduced, or not making these methods pure virtual in the first place, as was done ind0da5061ce(Dirty hack to allow generic wxDatePickerCtrl to compile under MSW., 2011-10-20), but didn't really fix the problem. Do fix it now by using different hierarchies for the native and generic classes. The main disadvantage of doing it is that there is no common base class for wxTimePickerCtrl and wxTimePickerCtrlGeneric providing SetTime() and GetTime() methods any more, but this seems like a relatively small price to pay because real applications won't be using these two classes simultaneously, as the calendar sample does, anyhow.
