How to Display Custom Objects with Cell Factories in JavaFX?

Cell Factories for Custom Objects Display in ListView

In your JavaFX application, you have a ListView that needs to display custom Word objects, each containing a word and its definition. However, the ListView currently shows the Word objects themselves as Strings instead of the wordStrings.

Cell factories provide a solution to this problem. By using a cell factory, you can specify how the ListView should extract the necessary data from the objects and display it in the cells.

To implement this using a cell factory:

<code class="java">listViewOfWords.setCellFactory(param -> new ListCell<Word>() {
    @Override
    protected void updateItem(Word item, boolean empty) {
        super.updateItem(item, empty);

        if (empty || item == null || item.getWord() == null) {
            setText(null);
        } else {
            setText(item.getWord());
        }
    }
});</code>

In this cell factory, the updateItem method extracts the word property from the Word object and sets it as the text of the cell.

Ensure that the cell factory is set on the ListView with the setCellFactory method, and your ListView will now correctly display the wordStrings of the Word objects.
