Doc from javafx.scene.layout.Region.getUserAgentStylesheet.

An implementation may specify its own user-agent styles for this Region, and its children, by overriding this method. These styles are used in addition to whatever user-agent stylesheets are in use. This provides a mechanism for third parties to introduce styles for custom controls.

The URL is a hierarchical URI of the form [scheme:][//authority][path]. If the URL does not have a [scheme:] component, the URL is considered to be the [path] component only. Any leading '/' character of the [path] is ignored and the [path] is treated as a path relative to the root of the application's classpath.

Subclasses overriding this method should not assume any particular implementation approach as to the number and frequency with which it is called. For this reason, attempting any kind of dynamic implementation (i.e. returning different user agent stylesheet values) based on some state change is highly discouraged, as there is no guarantee when, or even if, this method will be called. Some JavaFX CSS implementations may choose to cache this response for an indefinite period of time, and therefore there should be no expectation around when this method is called.

protected void updateItem(Integer item, boolean empty)

Overrides javafx.scene.control.Cell.updateItem.

Doc from javafx.scene.control.Cell.updateItem.

The updateItem method should not be called by developers, but it is the best method for developers to override to allow for them to customise the visuals of the cell. To clarify, developers should never call this method in their code (they should leave it up to the UI control, such as the javafx.scene.control.ListView control) to call this method. However, the purpose of having the updateItem method is so that developers, when specifying custom cell factories (again, like the ListView cell factory), the updateItem method can be overridden to allow for complete customisation of the cell.

It is very important that subclasses of Cell override the updateItem method properly, as failure to do so will lead to issues such as blank cells or cells with unexpected content appearing within them. Here is an example of how to properly override the updateItem method: 

protected void updateItem(T item, boolean empty) {
    super.updateItem(item, empty);

    if (empty || item == null) {
        setText(null);
        setGraphic(null);
    } else {
        setText(item.toString());
    }
}

Note in this code sample two important points:

  1. We call the super.updateItem(T, boolean) method. If this is not done, the item and empty properties are not correctly set, and you are likely to end up with graphical issues.
  2. We test for the empty condition, and if true, we set the text and graphic properties to null. If we do not do this, it is almost guaranteed that end users will see graphical artifacts in cells unexpectedly.
