Hi is it possible to put images in the Listbox because I would like to have:
a panel with images and a vertical scrollbar.

thanks in advance

Not out of the box. I believe the default cell renderer for listbox just calls String.valueOf(object) for its output. You can make your own cell renderer, though.

Yep, you just need to make your own cell renderer that converts from your model to whatever Panel you want.

This is the code that default cell renderer uses:

github.com

jMonkeyEngine-Contributions/Lemur/blob/master/extensions/LemurProto/src/main/java/com/simsilica/lemur/list/DefaultCellRenderer.java#L107


    if( this.style == null ) {
        this.style = style;
    } 
}
public void setTransform( Function<T, String> transform ) {
    this.transform = transform;
}
public Function<T, String> getTransform() {
    return transform;
} 
 
public ElementId getElement() {
    return elementId;
}
public String getStyle() {
    return style;
}

It should be easy to see how to set an icon/image to the button instead of text.
