Java : ignore single click on double click?

Question

can anyone think of a good way to ignore the single click that comes with a double-click in Java ?

I'm looking to have different behaviors for each such that:

• single-click paints crosshairs on the click point
• double-click selects an object on the screen, but should not paint crosshairs on the click point

... can anyone think of a way to do this ? Some sort of timer set-up maybe ? An ideas appreciated :-)

<disclaimer> ...and yes, I know I'm committing a most heinous usability / UI faux pas. </disclaimer>

EDIT #2:

Even though this works the delay due to the timer is maddening - I'm abandoning this solution, and using middle-click for selection instead of double-click...

EDIT:

Thanks cgull - this is what I was able to come up with given your confirmation that there's no easy way to do this (note that if I set the timer < 200 odd racing is seen between the click & the timer, but as long as I set this to a value > 200 things work just peachy) :

public void mouseClicked(MouseEvent e) {
    System.out.println( "Click at (" + e.getX() + ":" + e.getY() + ")" );
    if (e.getClickCount() == 2) {  
        System.out.println( "  and it's a double click!");
        wasDoubleClick = true;
    }else{
        Integer timerinterval = (Integer) 
          Toolkit.getDefaultToolkit().getDesktopProperty(
                      "awt.multiClickInterval");
        timer = new Timer(timerinterval.intValue(), new ActionListener() {
            public void actionPerformed(ActionEvent evt) {
                if (wasDoubleClick) {
                    wasDoubleClick = false; // reset flag
                } else {
                    System.out.println( "  and it's a simple click!");
                }
            }    
        });
        timer.setRepeats(false);
        timer.start();
    }
}

Indeed you'll need to set up a Timer in your overridden mouseClicked() method of your MouseAdapter to detect the time interval between the two clicks. The default interval in ms can be found by querying Toolkit.getDefaultToolkit().getDesktopProperty("awt.multiClickInterval"). If another mouse click is detected before the timer expires, then you have a double-click, else once the timer expires, you can process the single-click.
