Tak zacatecnik jsem v pythonu jako oop. Proceduralne delam dele. Chapu ze se da vsechno napsat zjednodusene, ale neni to muj denni chleba (tak delam dlouhy praseci kod), a jak se rika ucel sveti prostredky a furt se ucim. Fungovani nejak podivne znamenalo, ze se po odklepnuti dialogou pro vyber directorare objevilo okno kde slo zaskrtnout prefix. Ale nepodarilo se mi nejak dostat promenou (promenou i v metode what_prefix), ktera symbolizovala co bylo zaskrtnuto do casti kde bych ji mohl rozumne zpracovat. Zkusim najit ten kod. Spis si ale myslim, ze jsem to pojal filozoficky spatne a asi se to takhle delat neda, inu zacatecnik:). K tem prefixum, jedna se o adresar obsahujici typove soubory: slice_BMP.001, slice_BMP.002 atd, ale muze se tam vyskytnout i vice prefixu napr: bla.001, bla.002. Takze chci dat uzivately moznost zvolit s jakou mnozinou souboru bude program pracovat. Vlastne timto chci dostat prefix souboru, ktery je pak argumentem pro bmbreader pro knihovnu VTK.
