[Haskell-cafe] Evaluation of IO actions in record assignment

Hi.
I'm toying around with GTK2Hs and one of the things I'm doing
is stuffing a bunch of widgets in a record.
The problem is that the function that fetches a widget from the
Glade file returns IO Widget while my structure contains Widget's.
The best I've come up with is simply evaluating the actions by
putting the result in temporaries and then building the record.
Is there an easier way to accomplish this?
signatureEntry <- xmlGetWidget xml castToEntry "signatureEntry"
passwordEntry <- xmlGetWidget xml castToEntry "passwordEntry"
repeatEntry <- xmlGetWidget xml castToEntry "repeatEntry"
return UserPanel {userPanelSignatureEntry = signatureEntry,
userPanelPasswordEntry = passwordEntry,
userPanelRepeatEntry = repeatEntry}
Thanks,
Adde
