I need to make a selection-menu for crewmembers in my game.
I have made a support function that builds an image containing the needed profile info for each crewman (item) in the menu.
So, say I have an array of BufferImage and an array of AbleCrewman (the object type I want to list).
I need a scrollable list component displaying the images, while giving me either the index or object when the player selects one from the list.
I have been looking in the source codes for the engine, and the closest existing component I have found, is ListField.
Now, ListField seems to not support images, only text, and have a unused property called 'buttonSprite'.
(this also seems ironic, since it creates ImageComponent objects to render the menu-text)
I could always make my own UI component for this, but that would take time.
Is there an existing component I can use for this?

I've adressed this issue and made using images as ListField content a bit easier with ~~~~this commit.
You can now initialize a ListField of images as follows:

 Resources.images().get("e2.png"),
 Resources.images().get("e3.png"),
 Resources.images().get("e4.png") };
 ListField lf = new ListField(200, 200, 126, 504, images, 3);
 this.getComponents().add(lf);

This works fine as long as you don't need any textual information here, in which case you would have to write some custom behaviour for the component.

So you added a check for whatever parameter content is an Image?
That's perfect. I can definitely work with that!

KvaGram Yes, that's basically the one thing I changed :)
