Injection of root element

[sideisra]

Hi, would it be possible to inject the root element of a view into the code behind (view) via a special annotation or something?

At the moment I need to know the fx:id of the element I want to inject into the view. But often the root element has no fx:id and I don't want to give it a common fx:id (or I can't force the creator of the fxml to do so ;-)).

I think of something like:

@InjectRoot
Node rootNode;

The injected Node should be the root node of the fxml. When the fxml is included in another fxml it should still be the root node of this fxml and not of the whole scene graph.

Given the following example files:

• MainView.java
• MainViewModel.java
• MainView.fxml
• SubView.java
• SubViewModel.java
• SubView.fxml

where SubView.fxml is included into MainView.fxml via fx:include.

When I understand you correctly you want to inject the root Node of SubView.fxml into SubView.java and the root Node of MainView.fxml into MainView.java?

Would the fx:root mechanism fit to your requirements? With this approach you extend the view from a node. In this case the View is automatically the root container and contains the children.

@lestard yes exaxctly :-)
@sialcasa I don't think this mechanisms works for me. I don't want to write my own control.

The oracle documentation is misleading. You can use this approach to implement custom components not custom controls (control api). I recommend to have a short look on this approach.

The fx:root mechanism works for the fxml that is loaded directly via FluentFXMLLoader but not for included FXML.

Maybe this can be implemented with Java 9 LoadListener
