Hi
Our team is porting a WinCE app to MT. This app is quite complex
(native, SqlServerCE,
image/jpeg manipulation etc), so our clients are trying to retain as
much code as they can.
So in first run/spurt we created all WinForms CE Forms as xibs and did
some proof-of-concept
bindings to business logic.
In the xib for Image manipulation (MainForm) we have created UIImageView
and filled it with
some test jpegs through UIImage.
[Outlet]
UIImageView CustomViewControl { get; set; }
So in order to reuse his code our client has changed .designer.cs file into:
[Outlet]
CustomViewControlType CustomViewControl { get; set; }
and changed that CustomViewControlType inherits form UIImageView.
OK. Let us not discuss why .designer.cs is changed though there is
comment at the beginning.
It is done and let us work from here.
BTW @Xamarin MT team - good job with Xcode and MT integration. Adding
new Outlets to
Xib did not alter change above - new Outlets were added w/o overwritting
existing code!
This step broke Xcode loading of xibs, so [Register] attribute was added
to CustomViewControlType
and everything went fine - until our client has noticed that
CustomViewControl is created,
but the type is UIImageView, not CustomViewControlType !
So questions:
1. what would be preferred pattern/solution here?!
our brainstorming discussion results in order from easier to more
difficult:
1. make ctors visible -with Register attribute - NOGO
[Register] is for class level canot be applied on ctors and methods!
2. extension method on SomeMethod(this UIImageView, params);
3. replacing inheritance with aggregation+ exposing all methods
like implementing multiple inheritance.
4. some trick of the trade by Xamarin guys?!?
thanks
regards
mel
