public class ProblemTimer

extends javax.swing.JComponent

implements java.lang.Runnable

I think seven-segment LED-looking displays are cool. This one is rotated 90 degrees and counts down how many points you can still get for submitting the current problem (you can watch your points slip through your fingers!) The graphical code comes from some old game programming I did.

Constructor Detail

ProblemTimer

public ProblemTimer()

Creates the new widget and initializes the polygons (aren't you glad I only generate those once?)

Method Detail

resetPrefs

public static void resetPrefs()

Causes the animation delay and colors in the widget to be reset from the preferences.

run

public void run()

The method run by the thread "anim". Repeatedly repaints and waits.

Specified by:

run in interface java.lang.Runnable

paint

public void paint(java.awt.Graphics g)

Draws the seven-segment display with the current point value.

Overrides:

paint in class javax.swing.JComponent

select

public void select(int problemID,
                   double points)

Changes which problem is being looked at. If problemID is a new problem, it starts the timer for that problem. Otherwise, it reloads the data it has for when the problem was started (note that points is ignored in this case).

stop

public void stop()

Kills the timer thread.
