    <p>I am creating a list of cards that users can select from to start a game. Users select their cards by a checkbox next to the card name, and they are only allowed to select 10 cards. I want to be able to limit the number of checkboxes that can be selected by having an event handler get called when a checkbox is clicked and determine whether the checkbox is allowed to be clicked or not. How can i add an event handler to every checkbox to do this? If there is a better way, i am definitely open to suggestions. Here is my code where i setup the listview and the checkbox callback:</p> <pre><code>ListView&lt;Card&gt; cards; Callback&lt;Card, ObservableValue&lt;Boolean&gt;&gt; checkBoxCallback = new Callback&lt;Card, ObservableValue&lt;Boolean&gt;&gt;() { @Override public BooleanProperty call(Card card) { return card.selectedProperty(); } }; StringConverter&lt;Card&gt; cardToStringConverter = new StringConverter&lt;Card&gt;() { @Override public Card fromString(String card) { try { return CardFactory.createCard(card); } catch (Exception e) { e.printStackTrace(); } return null; } @Override public String toString(Card card) { return card.toString(); } }; Callback&lt;ListView&lt;Card&gt;, ListCell&lt;Card&gt;&gt; listViewCallback = CheckBoxListCell.forListView(checkBoxCallback, cardToStringConverter); cards.setCellFactory(listViewCallback); cards.getSelectionModel().selectedItemProperty().addListener(new ChangeListener&lt;Card&gt;() { @Override public void changed(ObservableValue&lt;? extends Card&gt; obsValue, Card oldValue, Card newValue) { cardImageView.setImage(newValue.getCardImage()); } }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
