Enhance controls with Swing style actions #90

Closed devent closed 4 years ago

devent commented 4 years ago

Hello. I am starting to use Lemur for my gui and there is some stuff I am missing.

For example, how would I react to the user finishing input a text in the TextField GUI element by pressing either Enter or Tab?

In Java Swing all components have Action(s) assigned to them and I can add an ActionListener that is informed with an ActionEvent after the user is finished entering or clicking on the field/button. See https://docs.oracle.com/javase/7/docs/api/javax/swing/JTextField.html#addActionListener(java.awt.event.ActionListener)

I would like to enhance Lemur components with Java Swing Action and ActionListener that will do so likewise. Java Swing Action would be the sensible choice because I don't like to re-implement all the classes and interfaces.

I also looked into ActionButton and it have an implementation of Action. But a) it doesn't follow the style approach of Lemur, i.e. I can't set the icon in the groovy-style file. b) I need to sub-class Action and I can't just add multiple ActionListener(s) to it.

Would be there any interest for that in Lemur? Is my assessment wrong in any part?

I just though that Java Swing would not be included in Android. Is that the reason why Lemur wasn't using that approach? That would make sense.

How about Javafx EventHandler? There is a free Android port for Javafx: https://docs.gluonhq.com/javafxports/

Is it possible for you to ask this question on the jMonkeyEngine forum?

Lemur's text field already supports actions similar to Swing.
