Implement a Mouse Listener and another Listener

HI, i was wondering if it was possible to implement an Actionlistener and a Mouselistener at the same time, kind of like this (Syntax is impossible i know, but just to show a point)
public class TrafficLight extends JApplet implements ActionListener and MouseListener ---You can't do it like that----, but if anybody knows how to actually do it, I would greatly appreciate it.

When i do that, i get this error
TrafficLight is not abstract and does not override abstract method mouseExited(java.awt.event.MouseEvent) in java.awt.event.MouseListener
And i am doing this,
public void mousepressed (MouseEvent e){
}and this
jLabel2.addMouseListener(this);I am probably forgetting somethig really simple.

Advice to implement a mouse listener for card game

Hi,
I am wondering about the best way to apply a mouselistener in my card game.
- i only want to listen for 'clicks'
- I have a JFrame with a JPanel inside. The JPanel has a null layout and many JLabels. The JLabels are the cards, i want to listen for mouse clicks on these 'cards'
I have seen it is not possible to apply a mouse listener to a JPanel or JLabel so is the most efficient way to apply the listener to the JFrame and then use getComponent () to determine which JLabel has been clicked ? or is there a better way ?
any thoughts appreciated . .

hey dubai, thanks for your quick help today, it is much appreciated !
i know the event should provide a reference to the source, i use the toString to overide the methods in the mouseEvent object and im printing this string to the console. It gives me the correct dimensions within my JPanel of where i clicked but the source is always given as the panel name. Have you any idea why it does not return the name of the JLabel ? I checked out the Action interface, thanks, it cud be very useful to seperate the code by using this.

How can i implement a mouse listener event on jtable cell?

I create JTable using a resultset,at the end of each row i add an image using JLabel(set imageicon of the JLabel).
i want to track the event when user click on that image.
What can i do for that?.
I tried by implementing mouseListener interface for the JLabel but it's not working properly.

Hi,
Add MouseListener to the JTable.
when the user clicks on the table use the method
getValueAt( int selectedRow,int selectedColumn) to get the contents.
Object obj = getValueAt( int selectedRow,int selectedColumn) .
(If obj instance of JLabel)
do your functionality.
Hope this helps
Cheers :)

My 13" macbook pro isnt starting up. I goes to a grey screen and flickers between the mouse icon and then the spinning start up icon. any ideas?

I have just updated my macbook pro 13" with requested updates and asked me to restart. Upon restarting it went to the grey startup screen where it just sticks flashing betwwen shades of grey. One shade which the mouse pointer and another shade with the start up wheel?
Any suggestions would be a great help.

You may be having a hardware problem that you cannot resolve on your own. Nevertheless...
...hold down the command and R keys whilst booting to try to get to your Recovery partition. If you can, use Disk Utility to try to Verify your boot drive (usually named "Macintosh HD" unless you've renamed it). If the verification fails, try to repair your hard drive. If everything appears to be OK, restart.
If you can't get into your Recovery partition, your problem is likely hardware related. If so, keep your appointment and see what the Apple techs have to say.

Recently purchased song and another I transfered into my ITunes library vannot be set up in a playlist.I get the message"file cannot be located".Originally I could listen to the purchased song but now that will no longer play.What do I need to do to ?

Recently purchased a song from ITunes and another that I downloaded from a CD will not transfer to a playlist and will not even allow me to listen to the songs.I get the message "file cannot be located"What can I do to get my system to locate the file?Originally I could play the songs from my desktop and I was able to transfer to my IPad.

Because the location for each song in your library is on your hard drive. If the hard drive isn't there, how can iTunes play it?
You'll have to move/copy the music from your hard drive to your computer's hard drive.
Basically, EASIEST way to do all this, if you don't care about your play counts, etc...
-Delete EVERYTHING from iTunes, so that your library is now empty.
-Go to "Advanced" inside of the "Preferences" window, found in the "Edit" drop-down. You can also access Preferences by pressing Ctrl+, (Press Ctrl and the comma key)
-Change your iTunes Media Folder Location to something simple, but on your computer. I use C:/iTunes. Make sure "Keep iTunes Media Folder Organized" and "Copy files to...." are both checked. You can close Preferences now.
-Now, drag and drop your music from your hard drive into your iTunes library. iTunes will automatically add the music to your library, as you would expect, and also creates a copy of each file to place into that iTunes Media Folder you just created.
Shouldn't have any more problems...

I have the next problem: when i'm listening music and i change a song it's appears the background of my iPod between a song and another. This happens after install iOs5 =[

Please help me

I opened a new user on my computer yesterday with administrative privledges. I then opened up an itunes account from this new user. It seemed to go pretty well. I haven't downloaded any new songs yet or moved them to my account. I don't know how to move songs yet. I'm reading iPod and iTunes for Dummeies. Very appropriate for me. I will let you know when I manage to do this and am successful. Once again, thank you for your kindness and help. Kay 205

How to Call action Listener from Mouse Listener event

One class (class 1)implements mouse listener and responds to a mouse events.
As part of that response it needs to call a variable set method in another class (class 2)and also have that setMethod call it's own ActionPerformed.
Seems the problem is I don't have aaction event to pass
I only have a mouse event. As follows:
class 1
public void mousePressed(MouseEvent e) {
int y1=Math.abs(e.getY()-y);
this.sourceReference.setVar(y1);
repaint();
class 2
int var;
public void setVar(int y)
var=y;
this.ActionPerformed(?? ); //This is what I want to do
Same question slightly different.
From class 1 I scould first call the setVar method
and then issue a call to class 2's ActionPerformed.
But again I don't seem to have the proper action event e to pass it.
Thanks

Do you need any information from an ActionEvent that you'd be calling from the MouseEvent (ie the action command, or somethig) or can you just have the actionPerformed method just call a different method that doesn't need an ActionEvent?
public void actionPerformed(ActionEvent e) {
this.doActionStuff();
public void doActionStuff() {
// does what you want the action event to do
Then from the mousePressed method you can just call the doActionStuff method.
I'm not sure if this helps or not, hope it does.

Remove mouse listener

hey, im using an itemStateChanged assigned to a List() and then im using a mouse listener to listen for a double click on the List(). the problem is that every time the mouse it double clicked another listener is added on top. So i need to remove it after the event is executed. If you can suggest a better way, please do, but im only a novice.
thanks
Pedge
class listItemListener implements ItemListener
public void itemStateChanged(ItemEvent event)
mainList.addMouseListener(new MouseAdapter()
public void mouseClicked(MouseEvent e)
if (e.getClickCount() == 2)
doClick();
}// end of inner class listItemListener

Wouldn't you just move the addMouseListener outside the ItemListener? Are you saying you want to remove the listener and then add it right back? I would guess you want:
class listItemListener implements ItemListener
private MouseAdapater ma;
public listItemListener()
ma = new MyMouseAdapter();
mainList.addMouseListener(ma);
public void itemStateChanged(ItemEvent event)
// do other stuff here
}// end of inner class listItemListener
class MyMouseAdapter extends MouseAdapter
public void mouseClicked(MouseEvent e)
if (e.getClickCount() == 2)
doClick();
}

Problem with JPanel's mouse listener!

I am developing a Windows Explorer-like program. I have an JPanel and added JLabels to that panel to reprensent the folders. I think, I kind of have to add mouse listener to JPanel to interact with mouse clicks, gaining and losing focus of JLabels etc. instead of adding every JLabel to mouse listener. So when I added to JPanel a mouse listener, it didn't work how I had expected. When I clicked on labels mouse click events didn't fire but when I clicked somewhere else in the panel it did fire. Is this a bug or am I using mouse listener incorrectly??
Thank for advance :)
Here is my JPanel's mouse listener ->
public void mouseClicked(MouseEvent e) {
int x = e.getX();
int y = e.getY();
System.out.println("Mouse Clicked");
Component c = this.getComponentAt(x,y);
if(c instanceof JLabel){
JLabel label = (JLabel) c;
label.setBackground(Color.LIGHT_GRAY);
}

My main problem is as in windows explorer (if CTRL or SHIFT not pressed) there is only one selected folder (in my case JLabel) and transfering "selection" to one label to another might need lots of extra code.. So I thought using JPanel's mouse listener can overcome this handling problem. But if you are saying, this is the way it has to be done, then so be it :D :D

Changing the color of text while mouse listener.

Hi all. working on an assignment for school and I need a little hint.
I am creating an applet to basically input names in txt blocks, and then you hit a button that will move the names to a text area. Well the instructor asked us to use a mouse listener to change the color of the labels on the txt blocks. Basically when you hover your mouse over the button it is supposed to change the color of the button (for and back ground), and change the color of the labels on the txt blocks.
I just did a general setForground(color.blue);
for my labels default color and it seemed to do the trick, I used the following code to try to change the color of both the buttons and the txt block labels, but only the button works.
Please assist..
public class Assignment2 extends java.applet.Applet implements ActionListener, MouseListener {
public void mouseExited(MouseEvent e){
//Colors Back
setForeground(Color.blue);
btnAdd.setForeground(Color.red);
btnAdd.setBackground(Color.yellow);
//Clear Status bar
showStatus("");
public void mouseClicked(MouseEvent e) {
//empty Method
public void mousePressed(MouseEvent e){
//empty method
public void mouseReleased(MouseEvent e){
//empty method

HI,
Sorry for delay. I was not on my seat.
I've modified your code and the label colors are changing now on the mouse over or out events.
I did this only for a single label i.e. "First Name". Just have a look on the code and do the same for the rest labels.
If u feel any problem, then revert to me.

Its better you create your own panel to display each of the files, than to display the first element of the 'toGetFileView.getComponents()' In this way, you can add a mouse listener to each of those elements.

Tooltip/mouse listener question

Hi all-
I have a panel that contains various components that a user can move around. This is done by attaching a mouse listener and determining which component is currently being clicked/dragged.
For a particular panel, I would like to display the x,y coordinates of a component in a tooltip, preferably while the user is moving it (which may not be possible with tool tips), but at least so that a user can see the updated coordinates after the component has been moved.
However, when I setToolTipText for the component, it seems to override the mouse clicked events, and I can no longer even detect a click on the component.
Is there a way that I can use tooltips and detect mouse clicks on the same component? Am I missing something simple, or do I need to find another way to do what I want to?
Thanks
Greg

I searched posts last night but not today...oops.
Found one today where a suggestion to something similar by mpmarrone was to use a Popup. It's now working, although I'm still not sure why tool tip text seems to take control of the mouse listener...

Why does a JButton automatically have a mouse listener registered with it?

If I instantiate a JButton, I find there's a mouse listener already registered (see code below). Does anyone know why?
Looking at the source code for JButton, I can't see how this is. If a create a dummy subclass of AbstractButton (of which JButton is a direct subclass) and instantiate that, it has no mouse listeners, and likewize with Button. So what is it about JButton?
The reason I ask is that I've seen in a book on swing that you must call enableEvents(AWTEvent.MOUSE_EVENT_MASK) on a JButton if you want processMouseEvent to get executed. But it actually gets executed even if enableEvents hasn't been called, and the only reason for this is surely that there is a mouse listener registered, which there is, but why?
Might the reason be that JButton extends Accessible?
Code:
JButton jb = new JButton("Dummy");
MouseListener[] mls = (MouseListener[])(jb.getListeners(MouseListener.class));
JOptionPane.showMessageDialog(this, (new Integer(mls.length)).toString(), "Number of Mouse Listeners", JOptionPane.INFORMATION_MESSAGE);

Hello,
That listener is installed by the JButton's UI. You might want to have a look at the source code of BasicButtonUI and BasicButtonListener to understand what they are used for. For example, mousePressed in BasicButtonListener is used to call setArmed on the JButton.
My best advice is for you not to worry about this at all.

Need a Mouse Listener

I have a main menu with a series of buttons, when you press a
button, it triggers an animation for a fly-out menu with a series
of buttons to trigger other events. Everything works fine up to
this point.
What I need is an independent hit area underneath the buttons
on the fly-out menu so that when the mouse leaves the area, the
fly-out menu will retract. The current methods require that the
mouse be down or released, but I need a mouse listener for an
'over' and 'out' state so that when the mouse is over the hit area,
the fly-out menu will show and when the mouse leaves the hit area,
the fly-out menu will retract.
I've have googled and read and am now totally confused. Can
anyone point me in the right direction to solve this
problem?

you shouldn't need setInterval, and its incorrectly set up.
If you wanted to use a setInterval call instead of the onMouseMove
event then you could do it as follows (but its NOT good
programming, just providing it for illustrative purposes)
remove the line Mouse.addListener... etc (you wouldn't do
both an onMouseMove check and a setInterval check)
and put in
var ML = setInterval(mouseListener,"onMouseMove",500);
That should work... I haven't tested it. Nor do I recommend
it. I think you're better off with onMouseMove.
If you are going to use the setInterval its better to change
the name of the
onMouseMove everywhere that it appears to something like
onIntervalCheck just so it makes more sense to you if you
look at it later on (or for someone else too). Using onMouseMove
shouldn't be too demanding on the CPU - and if its noticeable it
should only be for very short bursts.
BTW You can also delete or comment out the trace actions...
they were just there to help you understand how it works. Best not
to leave them in when you do a final publish (or exclude trace
actions in your publish settings)

I have an application which consists of a GUI form, "EntryForm," and "DataForm," a collection of variables.
Clicking EntryForm's submit button sends the entries to DataForm.
The submit button is attached to a mouse listener "SubmitButtonHandler"
My Question: How can I attach an arbitrary number, up to five instances of EntryForm to ONE mouse listener?
I have tried this:
     final SubmitButtonHandler sbh = new SubmitButtonHandler( ...
     entryForm1 = new EntryForm();
     dataForm1 = new DataForm();
          entryForm1.submitButton.addMouseListener( sbh );
     entryForm2 = new EntryForm();
     dataForm2 = new DataForm();
          entryForm2.submitButton.addMouseListener( sbh );
     entryForm3 = new EntryForm();
     dataForm3 = new DataForm();
          entryForm3.submitButton.addMouseListener( sbh );
     entryForm4 = new EntryForm();
     dataForm4 = new DataForm();
          entryForm4.submitButton.addMouseListener( sbh );
     entryForm5 = new EntryForm();
     dataForm5 = new DataForm();
          entryForm5.submitButton.addMouseListener( sbh );
     ...In the mouse listener I have tried these approaches:
     public void mouseClicked( MouseEvent e ) {
          if ( e.getSource() == entryForm1.submitButton ) {
               System.out.println( "Clicked: entryForm1.submitButton" );
               // send the data to dataform1
          } else if( e.getSource() == entryForm2.submitButton ) {
               System.out.println( "Clicked: entryForm2.submitButton" );
               // send the data to dataform2
     public void mouseClicked( MouseEvent e ) {
          if ( e.getSource() == submitButton ) {
               if( e.getSource() == entryForm1.submitButton ) {
               // send the data to dataform1
               } else if( e.getSource() == entryForm2.submitButton ) {
               // send the data to dataform2
          } else if ( e.getSource() == anotherButton ) {
               ...In both cases, only ONE form's button registers and even that is screwy.
Can this approach be fixed so that the mous listener can discern between the various forms, or do I have to use five sets of forms and mouse listeners?
Many thanks in advance.

Hi,
Button1.addMouseListener(ourMouseListener);
Button1.setActionCommande("This is button 1");
Button2.addMouseListener(ourMouseListener);
Button2.setActionCommande("This is button 2");
In the "ourMouseListener" event method, you use this...
if((((JButton)event.getSource()).getActionCommand()).equals("This is button 1"))
Source code for Button1
if((((JButton)event.getSource()).getActionCommand()).equals("This is button 2"))
Source code for Button2
