HoverFeedbackPart [message #1805502]

Hello,

In HoverFeedbackPart is the visual with an effect defined. The default effect is DropShadow. How could we apply another hover effect?
I extended a customer HoverFeedbackPart and overrode the method getHoverFeedbackEffect. But I noticed that the HoverFeedbackPart is hard coded in DefaultHoverFeedbackPartFactory. Is it possible to make it configurable like the color or geometry provider? Thank you.

Hi Shenwei,

DefaultHoverFeedbackPartFactory asks the Guice injector to create an instance of HoverFeedbackPart. Therefore, the actual implementation can be exchanged by binding HoverFeedbackPart to a subclass.

class Module {
  configure() {
    bind(HoverFeedbackPart.class).to(CustomHoverFeedbackPart.class);
  }
}

If this is not sufficient in your case, then you have to exchange the factory and create your custom feedback part there.

I am not a big fan of the provider mechanism, because it clutters the module with verbose bindings. However, you are correct that it would be easier to exchange if done like that. I will think about this.

Best regards,
Matthias
