Missing method on SpAbstractWidgetPresenter to update the visual state that depends on the enabled block #1561

Open koendehondt opened 2 weeks ago

See #1559.

Given that SpAbstractWidgetPresenter>>#enabled: can take a block:

enabled: aBooleanOrValuable
    "Set if the widget is enabled (clickable or focusable).
    This can either be a boolean or a block returning a boolean."

    enabled := aBooleanOrValuable

as in:

presenter := SpPresenter new.
button := SpButtonPresenter new
    icon: (presenter iconNamed: #smallSave);
    enabled: [ false ];
    action: [ "do something" ];
    yourself.
presenter layout: (SpBoxLayout newLeftToRight
    add: button;
    yourself).
presenter open

SpAbstractWidgetPresenter should have a method, e.g. refresh, to update the visual state of an instance, so that the condition in the enabled block is evaluated again.

Koen I thought about introducing a tag for book. What do you think? Like that we can help esteban knowing that this is important for the book.

Very good idea.
