Using the emulator 4.2. Exercise 2 – Lab 1 preparation First, you must click somewhere on the image of the clock to give the applet keyboard focus (light blue area). Clicking the check box or another window will steal keyboard focus again. • Hold Shift to set clock time (button 1). • Hold Ctrl to set alarm time (button 3). • Hold Shift+Ctrl to toggle alarm on or off. • Use direction keys for buttons 2-6. The tow lines on the LCD display should be fairly obvious. The first line displays the current clock time. The second line displays the alarm time. When the alarm is set the separators in the alarm time turn into colons, otherwise they remain as underscores. When the alarm is beeping the separators will flash with the beeps of the alarm. Below the buttons is a small status field which displays the alarm status with a check box and the current input mode with three radio buttons. The radio buttons may not be manipulated directly, but the check box can be used to modify the alarm status (on/off). When either of the modes Set Time or Set Alarm is active the user may increase the digit under the cursor (indicated by an underscore) by pressing the up button (2), decrease the digit under the cursor with the down button (5), shift cursor left with the left button (4) and shift cursor right with the right button (6). 107
