will help you Firstly with C# how can we link events to objects - I am guessing event handlers? If so can each handler use separate code? class A {
public event EventHandler SomeEvent;
}
class B {
public B(A a) {
a.SomeEvent += (sender, e) => { Console.WriteLine("B's handler"); };
}
}
class C {
public C(A a) {
a.SomeEvent += (sender, e) => { Console.WriteLine("C's handler"); };
}
}
class EventHandler {
LinkedList<Action<object, EventArgs>> subscribers =
new LinkedList<Action<object, EventArgs>>();
public void Add(Action<object, EventArgs> f) {
subscribers.AddLast(f);
}
public void Remove(Action<object, EventArgs> f) {
subscribers.Remove(f);
}
public void Invoke(object sender, EventArgs e) {
foreach(Action<object, EventArgs> f in subscribers)
f(sender, e);
}
}

Basic slider event handling
Date : March 29 2020, 07:55 AM
Does that help You forgot to clear your Timeout and stopping Slider before init() (start) again I updated your fiddlevar interval, timeout;
function stopSlider() {
console.log("function: stopSlider");
clearTimeout(timeout);
clearInterval(interval);
}
$('.slides').on('mouseenter', function() {
stopSlider();
}).on('mouseleave', function() {
stopSlider();
timeout = setTimeout(init, pause);
});
function startSlider() {
// just a tip
// $('.loading').animate({"width": "0"}, 0); // makes no sense, use instead .css()
$('.loading').css('width', '0');
...

I want to use graphics in java with event handling

may help you . The problem is not that the ball gets painted multiple times, the problem is that old drawings are never cleared. When you override paint methods, it is recommended that you call the super method, so that it does its own stuff first . @Override
public void paint(final Graphics g) {
super.paint(g);
g.setColor(Color.red);
g.fillOval(x, y, 50, 50);
g.setColor(Color.blue);
g.fillRect(200, 300, 100, 80);
if (x > 180 || y > 280) {
g.drawString("Target hit!!", 80, 20);
}
}
@Override
public void paintComponent(final Graphics g) {
super.paintComponent(g);
g.setColor(Color.red);
g.fillOval(x, y, 50, 50);
g.setColor(Color.blue);
g.fillRect(200, 300, 100, 80);
if (x > 180 || y > 280) {
g.drawString("Target hit!!", 80, 20);
}
}
