Re: [scalafx-users] Howto convert IntegerProperty to ObservableValue

[Piotr Tarsa]

try to use the field "delegate" directly or import the "sfxIntegerProperty2jfx" implicit function from IntegerProperty object.

I'm trying to write cellValueFactory.

I've got error with naive method:

    [error]  found   : scalafx.beans.property.IntegerProperty

    [error]  required: javafx.beans.value.ObservableValue[Int]

What should I do to extract javafx obervablevalue from scalafx wrapper?

[Piotr Tarsa]

I haven't programmed in Scala for a long time (let alone ScalaFX), but I smell some API bug with generics. Though I could be wrong. As a workaround I suggest to make some explicit bindings, with the required parametrization.

I've tried to use delegate and got following error:

    [error]  found   : javafx.beans.property.IntegerProperty

    [error]  required: javafx.beans.value.ObservableValue[Int]

Yes, you're right. Even generics mechanism prohibits that. But ObservableValue interface doesn't exhibit setters.

Maybe you have applied @specialized annotation somewhere and that causes the problem?

Try making a subclass of IntegerBinding or ObjectBinding[Int] and see if that helps.

I may suggest that ObservableValue[Int] and ObservableValue[Number] is different kinds of observables. You can not cast first to second since, Number observable may be updated with Float value.
