Hi
I have two once features at eiffel-iup that works without problem with
GOBO but generate an error with EiffelStudio. The code is this:
expanded class IUP_INTERFACE
feature {ANY}
=C2=A0=C2=A0=C2=A0 iup_open: IUP
=C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 once
=C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 create Result.ini=
t
=C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 end
=C2=A0=C2=A0 .....
end
The class IUP is something like:
class IUP
=C2=A0=C2=A0=C2=A0 -- Class to handle the interface system of an iup appli=
cation
create {IUP_INTERFACE}
=C2=A0=C2=A0=C2=A0 init
feature {IUP_INTERFACE}
=C2=A0=C2=A0=C2=A0 init
=C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 -- Init the interface system
=C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 do
=C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0 .....
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 end
But I get the error:
Error code: VGCC(6)
Error: Creation instruction uses call to improper feature.
What to do: make sure that feature of call is a creation procedure,
=C2=A0 is not `once', and is available for creation to enclosing class.
Class: IUP_WIDGET
Source class: IUP_INTERFACE
Feature: iup_open
Creation of: Result
Target type: detachable IUP
Feature name: init
Line: 10
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 once
->=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 create Result.init
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 end
What is the problem here?
Regards
