Lab 02: Handling Events, Menus & Text Areas Stop Watch Revisited (2 Points) The exercise must be completed during the lab period. Overview The purpose of this exercise is to handle events from buttons in a number of ways Part 1: Starting with StopWatch.java (from Day04, or using mine from today's downloads) create a new GUI that looks like: My window is now 300x350. The root layout is VBox with three FlowPanes in it... fpTop, fpCenter and fpBot. Stop Watch 00:00.0 The TextField and TextArea are the same width (250 pixels) set with the setPrefWidth method of each The top two FlowPanes are centered (setAlignment(Pos.CENTER) The Bottom FlowPane is right aligned (setAlignment(Pos.BOTTOM RIHT). In this FlowPane are the two buttons plus a dummy JLabel of 5 spaces to keep the buttons from being crammed up against the right border. Start Now, when the Start button is clicked, the window will look something like this: Stop Watch -0 00:02.5 Note, a Lap button has appeared. When you click Lap, the current time is posted to the TextArea. If you click several times, you get a list of lap times in the TextArea Clicking Stop leaves the final time in the counter and the lap times in the TextArea. Also, the Lap button disappears (see the Button method setVisible) Clicking Start again will clear the counter and the TextArea for another run Lap Stop Lab 02: Handling Events, Menus & Text Areas Stop Watch Revisited (2 Points) The exercise must be completed during the lab period.
