Create individual components
Instead of creating the layout using layout annotations, it is also possible to only create the UI elements that are defined in a PMO by using UiCreator.
In the following example, the UI elements of a PMO are directly added to a Vaadin Div. In this case, the possibly existing annotation of the PMO class is ignored, only annotations on methods are respected.
| If the layout is as simple as in this example it would be much more convenient to write a custom layout annotation. Only use this approach to get more control over special cases of the layout. |
Filtering of Components
When using the UiCreator you can choose to create all UI elements from a PMO object (via the createUiElements(Object, BindingContext, Function<C, W>) method) or choose the elements you want to display yourself, for example by reading additional annotations (like @SectionHeader), by way of the method createUiElement(AnnotatedElement, Object, BindingContext, Function<C, W>) which takes a single annotated element as an additional argument and creates only the UI elements from that annotated element. You can obtain all annotated elements from ComponentAnnotationReader#getComponentDefinitionMethods(Class<?>).
