 |
|
I need help with making a method to get a white circle with a black
background.
On clicking a button the circle turns to black On clicking the button
again it turns back to the white circle with a black background again.
import aLibrary.*;
import java.awt.event.*;
import java.awt.Color;
public class DotBW extends Dot{
private AOval theDot;
public DotBW(int a, int b){
super(a, b, 50, 50);
//theDot = new AOval();
setColor(Color.black);
}
public void action(){
Color fillColor = this.getColor();
if (fillColor == Color.black) {
this.setToFill();
//this.setColor(Color.white);
//this.setToFill(Color.white);
} else {
//this.repaint();
this.setColor(Color.black);
this.setToFill();
}
this.repaint();
}//end if
}//end class |

if some one is to understand your code, they need to understand Dot
too.

Could it be that the code that draws a white circle is completely
commented out?

Well I just need to know the method to make the black and white dot.
It is with a black background by default when the program runs and on
clicking a button it fills up then clicking on the button again
un-fills it. I could not think of any other way to keep a black
background when it's supposed to be white. If I just toggle between
colors then I tend to loose the border when it changes to white so it
is there but you cannot see it.
import aLibrary.*;
import java.awt.*;
public abstract class Dot extends AOval{
public Dot(int a, int b, int c, int d){
super(a,b,c,d);
}
public abstract void action();
}//end class |

Nobody can know without looking at the code in "aLibrary". So ask your
teacher; this isn't an unreasonable question to ask.
