Pressing button Twice

I still don't understand how the second click will be known. This is what I have.

public void actionPerformed(java.awt.event.ActionEvent e) {

txtaDisplay.setText("You Clicked The " + e.getActionCommand() + " Button.");

if (e.getSource() == btnSouth ) {

isbtnSouthPressed = true;

}

else {

isbtnSouthPressed = false;

}

}

The actionPerformed method takes an ActionEvent as parameter which has no getClickCount() method. In this case you have to use a flag:

//declare a flag variable

private int clicked = 0;

//code in actionPerformed(ActionEvent ae) method

if(ae.getSource().equals(okButton)){

if(clicked == 1){

System.exit(0);

//clicked = 0; if you do not exit here clear the flag

}else{

clicked++;

}

}else{

clicked = 0;

}

When you compare object it is best to use "equals" and not "==".

Sorry, I pressed post instead of preview. I was going to offer some explanation as well.

I asked this same question a while back and I didn't just want to know if there had been two clicks but if the user had actually made a double click i.e. two clicks a very short time apart.

Someone helped me then and this is what I got:

private long myLastClick = 0.0;

myObject.addMouseListener(new java.awt.event.MouseAdapter() {

public void mousePressed(java.awt.event.MouseEvent evt) {

long timeBetweenClicks = System.currentTimeMillis() - myLastClick;

if(timeBetweenClicks < 500) {// half a second

doSomething();

}

myLastClick = System.currentTimeMillis();

}

}

);

When the button is clicked the time is stored and then next time it is clicked if the timeBetweenClicks is less than your threshold (I set it at 0.5 seconds) then it will run the desired code.

Hope this is helpful :)

Ben.

jquattro,

How come everyone people get so upset on this forum? I'm new to learning java and by reading that more adv java programmers get irritated with stupid questions makes me not want to post questions. I thought people were suppose to help you on here no matter how stupid the question is. I'm asking you this b/c I saw your name on a message I read. It was a guy asking a question not pertaining to java. I think the user name was like jaffasoft? Anyways, just wondering.

Hi,

To understand my answer you were reading take a look at this thread.

http://forum.java.sun.com/thread.jsp?forum=54&thread=189759

This was the initial posting of jaffasoft. And after I gave him some hints, and he also received more help from kksenji, he posted again with this text:"Obviously the dickhead that gave it to me, didn't give one that would work on all fields without all this bullshit about script signing tools."

You can read the entire thread to see what is all about. Anyway the point is I am willing to help but I would not accept this kind of language, even more after I spent time trying to give a solution.

If people are polite and willing to contribute to solving their problem (showing where they have got to, using the search forum facility before posting) they'll always get help.

If they are rude and/or expect other people to do their job/homework for them without making any effort, they may get helped but they may also get told to behave more suitably.

Your postings were clearly in the polite/contributing class so you get lots of help.

QED
