Listing 9-5 shows the createClipList method. This method creates a VBox to hold a Label , the three
Button s that play the AudioClip s, and a Hyperlink that triggers the display of the Code Monkey web page at
jonathancoulton.com in a separate window. The VBox is then added to the GridPane such that it spans all remaining
columns in the first row. The VBox is always centered horizontally in the grid and grows in both the horizontal and
vertical directions, taking up whatever extra space is available in the layout.
Listing 9-5. Constructing the Buttons That Play the AudioClip s
private void createClipList(GridPane grid) {
final VBox vbox = new VBox(30);
vbox.setAlignment(Pos.TOP_CENTER);
final Label clipLabel = new Label("Code Monkey To-Do List:");
clipLabel.setId("clipLabel");
final Button getUpButton = new Button("Get Up, Get Coffee");
getUpButton.setPrefWidth(300);
getUpButton.setOnAction(createPlayHandler(coffeeClip));
final Button goToJobButton = new Button("Go to Job");
goToJobButton.setPrefWidth(300);
goToJobButton.setOnAction(createPlayHandler(jobClip));
final Button meetingButton = new Button("Have Boring Meeting");
meetingButton.setPrefWidth(300);
meetingButton.setOnAction(createPlayHandler(meetingClip));
