Example 1 with Binding

use of org.terasology.rendering.nui.databinding.Binding in project Terasology by MovingBlocks.

the class NUIEditorMenuTreeBuilder method getFieldValue.

private Object getFieldValue(Field field, Class clazz) throws IllegalAccessException, InstantiationException {
    if (Enum.class.isAssignableFrom(field.getType())) {
        return field.getType().getEnumConstants()[0].toString();

                // The default - and acceptable - value for the AbstractWidget.family binding is null, but a user
                // most likely wants to use a custom family. Therefore, the default is set to an empty string instead.
                value = "";
            } else {
                Binding binding = (Binding) field.get(newInstance(clazz));
