Trying to perform an action when a button is pressed

I am trying to make a game and I made a Button class using the JButton library.
This code is in the button class:
#Override public void mouseClicked(MouseEvent e) { pressed = true; }
public boolean getPressed(){
return pressed;
}
Then in the main java file:
Button playButton = new Button("PLAY", frame);
frame.add(playButton);
while (true){
if (playButton.getPressed())
System.out.println("test");
}
It never seems to print test even though I checked and the boolean value is being changed

I am unfamiliar with JButton. But it seems that in your if statement in your while loop, there is no condition. Please reply if this helps!

JAVA SWING - Creating Animation using Swing Timer

I am trying to setup a program that enables the user to display a transition when clicking the next and previous button. When pressing next, the swing timer should trigger and start the animation. When transitioning, there should be a flag that states it is in the transition period. The Swing timer should fire once every tenth of a second and essentially last 1 second.
public class guiCreation {
static Timer timer;
static boolean flag = false;
private static void guiInterface() {
next.addActionListener(new ActionListener(){
timer = new Timer(1000, this);
public void actionPerformed(ActionEvent e){
nextGest();
}
});
//should go to the next tab
previous.addActionListener(new ActionListener(){
//if the list gets to the beginning, disable button
public void actionPerformed(ActionEvent e){
prevGest();
}
});
}
public static void nextGest() {
timer.start();
previous.setEnabled(true);
next.setEnabled(true);
//if the list gets to the end, disable button
if (cardLayout.isNextCardAvailable()) {
status.setText(" Next button has been clicked");
//System.out.println("This is the" + size);
cardLayout.next(cardPanel);
next.setEnabled(cardLayout.isNextCardAvailable());
}
}
public static void prevGest() {
if (cardLayout.isPreviousCardAvailable()) {
timer.start();
next.setEnabled(true);
previous.setEnabled(true);
status.setText(" Previous button has been clicked");
cardLayout.previous(cardPanel);
previous.setEnabled(cardLayout.isPreviousCardAvailable());
}
}
}

This: "The Swing timer should fire once every tenth of a second ..." -- does not agree with this: timer = new Timer(1000, this); Your Timer is firing once every second, not every 10th of a second.
Instead, you should:
Create a new Timer(100, ...), one that fires every 10th of a second
Store in an instance field the start time in msecs when the Timer begins (likely do this in your button's ActionListener)
Within the Timer's ActionListener get the current mSecs and use this to check the elapsed time
Stop the Timer via ((Timer) e.getSource()).stop(); once 1 full second has elapsed
No need for a flag, since all you need to do is to check if the Timer isn't null and if it .isRunning(). e.g., if (timer != null && timer.isRunning()) { -- then the animation is proceeding.
Unrelated suggestion:
Get out of the static world and into the instance world. You're programming in Java, a language that is built to use OOPs from the ground up, and you don't want to fight against the OOPs paradigm.

JButton Prints Multiple Times Instead of Once. Why?

I have a JButton and the code is below. When pressed it prints 3 times to the console instead of once. Why is it doing that and how to fix that? Thanks in advance! I also posted on code ranch.
change61 = new JButton("N");
change61.setLocation(0,0);
change61.setSize(25,14);
change61.setFocusPainted(false);
change61.setBorder(new LineBorder(Color.BLACK));
change61.setMargin(new Insets(0,0,0,0));
change61.setFont(new Font("Arial", Font.BOLD, 7));
change61.setRolloverEnabled(false); // TEST
change61.addActionListener(this);
change61.setActionCommand("Normal");
buttons16.add(change61);
change61.getModel().addChangeListener(new ChangeListener() {
#Override
public void stateChanged(ChangeEvent e) {
ButtonModel model = change61.getModel();
if (model.isArmed()) {
cl1.setIcon(CL2);
lvrvr1.setIcon(LVRL);
dsw1.setIcon(LSIG);
dsy1.setIcon(CL1);
b1b.setIcon(LHC);
System.out.println("Button Pressed"); // THIS GETS PRINTED 3 TIMES TO CONSOLE INSTEAD OF ONCE
} else {
cl1.setIcon(CL1);
}
}
});

Within stateChagned method, use isPressed instead of isArmed. It should work.
Or as #camickr suggested
change61.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
cl1.setIcon(CL2);
lvrvr1.setIcon(LVRL);
dsw1.setIcon(LSIG);
dsy1.setIcon(CL1);
b1b.setIcon(LHC);
System.out.println("Button Pressed"); // THIS GETS PRINTED 3 TIMES TO CONSOLE INSTEAD OF ONCE
}
});

Since the question got me hooked, I wanted to know why it is fired three times.
As the stacktrace reveals, the changes are fired by the mouse event.
First, the mouse is pressed. It calls DefaultButtonModel.isArmed(true) and DefaultButtonModel.isPressed(true). Each method triggers a change event. Here we have the first and second iteration.
Second, the mouse is released. It calls DefaultButtonModel.isPressed(false), again triggering a change event. The third iteration.
FYI, the DefaultButtonModel is the implementation of the ButtonModel- Interface.

set button condition based on other button condition

currently my program have a selection page which contain 4 action button with one terminate button and after the user click into one of the action button the button will set enabled (false) and i want to set terminate button in false mode when those 4 buttons are enabled but when 4 button is diabled than the terminate button will be enabled
do {
if (SIG.isEnabled() && RG.isEnabled() && AaCG.isEnabled() && SRG.isEnabled()) {
Terminate.setEnabled(false);
} else {
Terminate.setEnabled(true);
}
} while (Terminate.equals(false));
}
try to use do while loop but i dont know how to code it properly

Add an ActionListener to the button. The code it contains will be executed everytime the button is pressed.
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// Do your check here
if (SIG.isEnabled() && RG.isEnabled() && AaCG.isEnabled() && SRG.isEnabled()){
Terminate.setEnabled(false);
} else {
Terminate.setEnabled(true);
}
}
});
PD: According to the Java Naming Conventions, your variable, fields and method names should start with a lowercase letter, to not confuse them with a Class or an Interface.

Java: Double-Click a JSlider to Reset

I have a JSlider that sets the speed of my metronome, from 40 - 200, where 120 is the default, in the middle.
When the user clicks the metronome button, the metronome plays at the speed displayed on the JSlider - the user drags the slider to the right, the speed of the metronome increases, and it decreases if they slide it to the left.
How do I add functionality so that if the user double-clicks on the JSlider button, it defaults back to 120 - in the middle?
Here is my code:
public Metronome() {
tempoChooser = new JSlider();
metronomeButton = new JToggleButton();
JLabel metText = new JLabel("Metronome:");
add(metText);
...
tempoChooser.setMaximum(200);
tempoChooser.setMinimum(40);
tempoChooser.addChangeListener(new javax.swing.event.ChangeListener() {
public void stateChanged(javax.swing.event.ChangeEvent evt) {
tempoChooserStateChanged(evt);
}
});
add(tempoChooser);
...
}
private void tempoChooserStateChanged(javax.swing.event.ChangeEvent evt) {
final int tempo = tempoChooser.getValue();
if (((JSlider) evt.getSource()).getValueIsAdjusting()) {
setMetronomeButtonText(tempo);
} else {
processTempoChange(tempo);
}
}
thanks in advance!

This should help you out: http://docs.oracle.com/javase/tutorial/uiswing/events/mouselistener.html
You need to read up on that and implement MouseListener. You can use int getClickCount() to count how many times the user has clicked, which will help you read double clicks.
Hope this helps!

Even though I dont see a question, my gues is you are looking for MouseListener.

Not simple job, you have to add javax.swing.Timer and listening if during fixed period Mouse cliked once or twice times, for example

I recently wrote something similar so I could differentiate between single and double left mouse-button clicks:
private Timer timer;
#Override
public void mouseClicked(MouseEvent e) {
if(e.getButton() == MouseEvent.BUTTON1){
if (timer == null) {
timer = new Timer();
timer.schedule(new TimerTask() {
#Override
public void run() { // timer expired before another click received, therefore = single click
this.cancel();
timer = null;
/* single-click actions in here */
}
}, (Integer) Toolkit.getDefaultToolkit().getDesktopProperty("awt.multiClickInterval"));
}
else { // received another click before previous click (timer) expired, therefore = double click
timer.cancel();
timer = null;
/* double-click actions in here */
}
}
}
