    <p>How about creating a row factory which exposes an observable list of the indexes of table rows which are to be highlighted? That way you can simply update the list with the indexes you need to highlight: for example by calling the getSelectedIndices() on the selection model and passing it to the list's setAll(...) method.</p> <p>This could look something like:</p> <pre><code>import java.util.Collections; import javafx.beans.value.ChangeListener; import javafx.beans.value.ObservableValue; import javafx.collections.FXCollections; import javafx.collections.ListChangeListener; import javafx.collections.ObservableList; import javafx.scene.control.TableRow; import javafx.scene.control.TableView; import javafx.util.Callback; public class StyleChangingRowFactory&lt;T&gt; implements Callback&lt;TableView&lt;T&gt;, TableRow&lt;T&gt;&gt; { private final String styleClass ; private final ObservableList&lt;Integer&gt; styledRowIndices ; private final Callback&lt;TableView&lt;T&gt;, TableRow&lt;T&gt;&gt; baseFactory ; public StyleChangingRowFactory(String styleClass, Callback&lt;TableView&lt;T&gt;, TableRow&lt;T&gt;&gt; baseFactory) { this.styleClass = styleClass ; this.baseFactory = baseFactory ; this.styledRowIndices = FXCollections.observableArrayList(); } public StyleChangingRowFactory(String styleClass) { this(styleClass, null); } @Override public TableRow&lt;T&gt; call(TableView&lt;T&gt; tableView) { final TableRow&lt;T&gt; row ; if (baseFactory == null) { row = new TableRow&lt;&gt;(); } else { row = baseFactory.call(tableView); } row.indexProperty().addListener(new ChangeListener&lt;Number&gt;() { @Override public void changed(ObservableValue&lt;? extends Number&gt; obs, Number oldValue, Number newValue) { updateStyleClass(row); } }); styledRowIndices.addListener(new ListChangeListener&lt;Integer&gt;() { @Override public void onChanged(Change&lt;? extends Integer&gt; change) { updateStyleClass(row); } }); return row; } public ObservableList&lt;Integer&gt; getStyledRowIndices() { return styledRowIndices ; } private void updateStyleClass(TableRow&lt;T&gt; row) { final ObservableList&lt;String&gt; rowStyleClasses = row.getStyleClass(); if (styledRowIndices.contains(row.getIndex()) ) { if (! rowStyleClasses.contains(styleClass)) { rowStyleClasses.add(styleClass); } } else { // remove all occurrences of styleClass: rowStyleClasses.removeAll(Collections.singleton(styleClass)); } } } </code></pre> <p>Now you can do</p> <pre><code>final StyleChangingRowFactory&lt;Person&gt; rowFactory = new StyleChangingRowFactory&lt;&gt;("highlightedRow"); table.setRowFactory(rowFactory); </code></pre> <p>And in your button's action handler do </p> <pre><code> rowFactory.getStyledRowIndices().setAll(table.getSelectionModel().getSelectedIndices()); </code></pre> <p>Because StyleChangingRowFactory wraps another row factory, you can still use it if you already have a custom row factory implementation you want to use. For example:</p> <pre><code>final StyleChangingRowFactory&lt;Person&gt; rowFactory = new StyleChangingRowFactory&lt;Person&gt;( "highlightedRow", new Callback&lt;TableView&lt;Person&gt;, TableRow&lt;Person&gt;&gt;() { @Override public TableRow&lt;Person&gt; call(TableView&lt;Person&gt; tableView) { final TableRow&lt;Person&gt; row = new TableRow&lt;Person&gt;(); ContextMenu menu = new ContextMenu(); MenuItem removeMenuItem = new MenuItem("Remove"); removeMenuItem.setOnAction(new EventHandler&lt;ActionEvent&gt;() { @Override public void handle(ActionEvent event) { table.getItems().remove(row.getItem()); } }); menu.getItems().add(removeMenuItem); row.contextMenuProperty().bind( Bindings.when(row.emptyProperty()) .then((ContextMenu) null) .otherwise(menu)); return row; } }); table.setRowFactory(rowFactory); </code></pre> <p><a href="https://gist.github.com/james-d/7813134">Here</a> is a complete code example.</p>

    1. COIn JavaFX8, you could probably rewrite this using a pseudoclass instead of manipulating the style classes directly. I think this would be much more efficient, and probably a bit nicer.

    2. COI really appreciate the effort of taking your time and writing a long answer like this, but I was looking for something more comprehensible, a bit cleaner and easier to follow. I've tried your code and it works as expected, now I'm trying to figure out where that "auto-refresh table" thingy is coming from and how to implement it in somewhat simpler form into my code, if possible.

    3. COThe refresh happens because there is a listener registered with the list of row indices which updates the style class for the row whenever the contents of the list change: styledRowIndices.addListener(...); JavaFX is really powered by the observable properties and collections: you can't really get very far without understanding those and there's really very little here other than listening to properties and an observable list for changes. There's a tutorial on properties [link](http://docs.oracle.com/javafx/2/binding/jfxpub-binding.htm)here[/link].

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.
