It sounds like your problem is much closer to the Bar Tab example than the CRUD one.
The basic idea for adding new widgets--along with new behaviors and events--is to use so-called "dynamic event switching". Essentially, this is a way to put newly created events and behaviors back into your network.
The action to create a new widget has two parts. The first part is to just create the widget, using liftIO
. The second is to get its inputs and use trimE
or trimB
as appropriate. Leaving out most of the GTk-specific details (I don't know how to use GTk :P), it'll look something like this:
let newSeries name = do
label <- liftIO . labelNew $ Just name
liftIO $ tadd labelNew 0
{- ... the rest of your controls here ... -}
seasonNumber <- trimB $ getSpinButtonBehavior seasonButton
{- ... wrap the rest of the inputs using trimB and trimE ... -}
return (label, seasonNumber, ...)
So this function creates a new widget, "trims" its inputs and returns the values to you. Now you have to actually use these values:
newSeasons <- execute (FrameworkMoment newSeries <$> nameEvents)
here nameEvents
should be an Event String
containing an event with the name of the new series each time you want to add it.
Now that you have a stream of all of the new seasons, you can combine it all into a single behavior of a list of entries using something like stepper
.
For more details--including things like getting the aggregate information out of all of your widgets--look at the actual example code.
