I'm experimenting with wxHaskell, and I've got something like:
main = run mainFrame
mainFrame = do -- main application frame
...
cbEdit <- checkBox p1 [text := "Edit Mode", on command ::=
onCbEdit textlog]
...
where
...
It would be useful to have some convenience function, let's say,
isEditing, which works out whether cbEdit is checked, or not. That way,
one could just pass this in as a parameter without requiring any extra
code. The problem is, I can't see how it can be done. I've tried various
things in the main section, and nothing worked. I tried putting the
following defintion into the where clause:
isEditing = do
checkedp <- get cbEdit checked
return checkedp
but the compiler complained that cbEdit is not in scope. I /could/ pass
in cbEdit as a parameter to isEditing, but I'd rather not.
