Question

 (This is using JavaFX) Write a program that uses a BorderPane that: 1. starts with two buttons on the bottom and your name on the screen and the two buttons should be programmed for up and down instead of left and right, similar to example 16.2. Only use the left half of the center for your name (1 row 2 columns). See number 5 below for the right half of the center. So you could use a GridPane for the center. 2. enhances 16.2 with checkboxes that permit your name to be bold and/or italicized but the font must be  something other than Times New Roman, and these checkboxes must be on the left (not the right) , similar to example 16.3 3. enhances 16.3 with  3 radio buttons that paint the text colors that are colors of your choice, but not red, green or blue, and these radio buttons must be on the right (not the left), similar to example 16.4. You can use RGB coloring if you like. 4. puts a bouncing red rectangle (not a ball)  at the top  with a slider for speed (see see 16.12).

final ChoiceBox panes = new ChoiceBox(); panes.getItems().addAll("Top", "Left", "Right", "Center", "Bottom"); panes.setValue("Top");

//Create a button to trigger which label is visible

Button moveBut = new Button("Show Pane"); moveBut.setOnAction(new EventHandler<actionevent>() { @Override public void handle(ActionEvent arg0) {

//Add the Button and ChoiceBox to the HBox showControls.getChildren().add(moveBut); showControls.getChildren().add(panes);
