Edit Question
Title
Body
I have written a small application which tracks my progress in TV Series. The application is written in Haskell with functional reactive programming (FRP) with reactive banana . The application can: add/remove new TV Series to the table change the season and episode of an series I have problems writing the code that adds a new TV series to the table and wires the new events. The CRUD example from here didn't quite help me because I have more requirements then just selecting an element from the list. How do I write a reactiveTable function like the reactiveListDisplay function from the CRUD Example in a FRP way? How can events be added for the remove button and the season and episode spin buttons after the network has been compiled? data Series = Series { name :: String , season :: Int , episode :: Int } insertIntoTable :: TableClass t => t -> SeriesChangeHandler -> SeriesRemoveHandler -> Series -> IO () insertIntoTable table changeHandler removeHandler (Series name s e) = do (rows, cols) <- tableGetSize table tableResize table (rows+1) cols nameLabel <- labelNew $ Just name adjustmentS <- adjustmentNew (fromIntegral s) 1 1000 1 0 0 adjustmentE <- adjustmentNew (fromIntegral e) 1 1000 1 0 0 seasonButton <- spinButtonNew adjustmentS 1.0 0 episodeButton <- spinButtonNew adjustmentE 1.0 0 removeButton <- buttonNew
