Question

I know this sound very simple, but I failed to combine two strings into a new one.

The IO String “a” from a gtk entry is fetched by

      a <- (entryGetText text_field)

The goal is to combine it like:

newstring = “Text: “+a

Any ideas to accomplish that?
Thanks!

Using string concatenation:

 do a <- entryGetText text_field
    let b = "Text:" ++ a
    return b

More simply:

 do a <- entryGetText text_field
    return $ "Text:" ++ a

You can play games too:

 ("Text:" ++) <$> (entryGetText text_field)
