I am having trouble figuring out how to get the roll button to work with my program. I can get the roll button to appear, but can't figure out how to get the listener to work . I don't want to have to keep re-running the program for it to work.
Here is my Die Class:
public class Die {
public static void main(String[] args) {
}
protected int face = 1;
void roll() {
face=(int)(Math.random()*6 + 1);
}
public int getFace() {
return face;
}
public int setFace() {
return face;
}
Here is my Graphics class where I make the dice:
public class Graphics extends Die {
private int x,y;
boolean locked;
public Graphics(int x, int y){
this.x = x;
this.y = y;
}
public void draw(DrawingKit dk){
Rectangle2D.Float die1 = new Rectangle2D.Float(x, y, 80, 80);
Ellipse2D.Float topleft = new Ellipse2D.Float(x+3,y+3,18,18);
Ellipse2D.Float topright = new Ellipse2D.Float(x+55,y+3,18,18);
Ellipse2D.Float middleleft = new Ellipse2D.Float(x+3,y+28,18,18);
Ellipse2D.Float middle = new Ellipse2D.Float(x+28,y+28,18,18);
Ellipse2D.Float middleright = new Ellipse2D.Float(x+55,y+28,18,18);
Ellipse2D.Float bottomleft = new Ellipse2D.Float(x+3,y+53,18,18);
Ellipse2D.Float bottomright = new Ellipse2D.Float(x+55,y+53,18,18);
dk.setPaint(Color.green);
dk.fill(die1);
if (face > 1) {
dk.draw(topleft);
dk.setPaint(Color.black);
dk.fill(topleft);}
if (face > 3)
{ dk.draw(topright);
dk.setPaint(Color.black);
dk.fill(topright);}
if (face == 6)
{ dk.draw(middleleft);
dk.setPaint(Color.black);
dk.fill(middleleft);}
if (face % 2 == 1)
{ dk.draw(middle);
dk.setPaint(Color.black);
dk.fill(middle);}
if (face == 6)
{ dk.draw(middleright);
dk.setPaint(Color.black);
dk.fill(middleright);}
if (face > 3)
{ dk.draw(bottomleft);
dk.setPaint(Color.black);
dk.fill(bottomleft);}
if (face > 1)
{ dk.draw(bottomright);
dk.setPaint(Color.black);
dk.fill(bottomright);}
}
public static void main(String[] args) {
}
}
Lastly, here is my roll code which effectively runs the program and displays the button:
public class Roll {
public static void main(String [] args ){
JPanel topPanel = new JPanel ();
JButton button1 = new JButton("Roll");
topPanel.add(button1);
int cnt1 = 1, cnt2 = 2, cnt3 = 3, cnt4 = 4, cnt5 = 5, cnt6 = 6;
DrawingKit dk = new DrawingKit("My Dice");
dk.addPanel(topPanel);
Graphics die1 = new Graphics(0,45);
die1.roll();
die1.draw(dk);
Graphics die2 = new Graphics(100,45);
die2.roll();
die2.draw(dk);
Graphics die3 = new Graphics(200,45);
die3.roll();
die3.draw(dk);
Graphics die4 = new Graphics(300,45);
die4.roll();
die4.draw(dk);
Graphics die5 = new Graphics(400,45);
die5.roll();
die5.draw(dk);
String s1 = String.format("val1 = %d", (int)10.5678);
// System.out.println(s1);
String result = String.format("Rolled a %d", die1.getFace());
System.out.println(result);
for (int i = 0; i< 60000; i++) {
die1.roll();
die1.setFace();
switch (die1.getFace()) {
case 1: cnt1++;;
break;
case 2: cnt2++;;
break;
case 3: cnt3++;;
break;
case 4: cnt4++;;
break;
case 5: cnt5++;;
break;
case 6: cnt6++;;
break;
default: System.out.print("Unexpected value");
System.out.println(die1.getFace());
}
}
System.out.print("Number of 1's ");
System.out.println(cnt1);
System.out.print("Number of 2's ");
System.out.println(cnt2);
System.out.print("Number of 3's ");
System.out.println(cnt3);
System.out.print("Number of 4's ");
System.out.println(cnt4);
System.out.print("Number of 5's ");
System.out.println(cnt5);
System.out.print("Number of 6's ");
System.out.println(cnt6);
}
}
Can anyone please explain to me what I am doing wrong and help me?
Thanks
After you create the JButton, you have to add an ActionListener for that button. Somthing like this:
button1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
// Whatever you want to do when the user clicks the button
}
});
For example:
public class Roll {
DrawingKit dk = new DrawingKit("My Dice");
Graphics die1 = new Graphics(0,45);
Graphics die2 = new Graphics(100,45);
Graphics die3 = new Graphics(200,45);
Graphics die4 = new Graphics(300,45);
Graphics die5 = new Graphics(400,45);
public static void main(String [] args ){
JPanel topPanel = new JPanel ();
JButton button1 = new JButton("Roll");
button1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
// Roll and draws the dices
rollDices();
drawDices();
}
});
topPanel.add(button1);
dk.addPanel(topPanel);
}
public static void rollDices() {
die1.roll();
die2.roll();
die3.roll();
die4.roll();
die5.roll();
}
public static void rollDices() {
die1.draw(dk);
die2.draw(dk);
die3.draw(dk);
die4.draw(dk);
die5.draw(dk);
}
}
