Thread: Why isn't the MouseListener showing the X and Y cords like I want it to?

    Cool Why isn't the MouseListener showing the X and Y cords like I want it to?

    It should work. I have a MouseListener and I told it to make a new window that will show, in brackets which it's not, the point where the mouse is on the first window. Well, I have a hard time getting both windows to show at same time as clicking on one minimizes the other unless I shrink them both.

    I edited stuff out to make the code shorter and only contain what appears to be directly related to the problem.

    However, don't pitch a fit and groan "It won't compile!" if I mistakenly deleted something important or missed something and deleted only half of it. I tried.

    Anyway, I was trying to get the location of the mouse on one screen to show up on the other and to repaint the JLabel, but it always says 0.0 for both no matter where the mouse is.

    Also, why do my windows keep opening up minimized when the program starts?

    I was hoping to track the Mouse Location so that I can figure out where to draw stuff later and not have to play guessing games for hours in order to find the best location to draw something to make it just right.

    Why are all of these component's on the editor weird?

    Also, the smiles are limited and there is a message popping up in yellow every once in while while I type that says "Auto-Saved" that I don't ever recall having seen before in the past.


    ^^
    Also, why is it storing my last text typed despite a page refreshed?

    You can get the mouse position using this code - http://www.javaprogrammingforums.com...-position.html

    I upgraded the forum software last night. The new editor is part of this upgrade.
    There was a slight problem originally but this has been fixed.

    As far as im aware, the "Auto-Saved" feature is for just incase the browser crashes or there is a problem when you are about to post. It saves your message as a draft.
    Please use [highlight=Java] code [/highlight] tags when posting your code.

    You clearly didn't even try to compile it... and sure enough, it doesn't compile. How do you know it demonstrates the problem if you haven't even compiled it?

    You have to understand that it's a waste of time complaining that it doesn't work, then posting code that won't compile. Even if I wanted to waste my time fixing it, I'm going to end up debugging code that isn't the code you're having a problem with.

    If you really want help with this problem, post compilable code that demonstrates the problem.

    Having said the above, I don't actually see anywhere that you add a MouseListener to a component, so I wouldn't expect any mouse action to be recognized. Of course, that may be part of the code you deleted...

    I had a larger program that DID compile. However, after being told again and again and again and again to make a SSCEE I decided to remove all the parts that weren't relevant to the problem.

    I tried to get all of the stuff out but I can't compile the smaller program if I use the same title.

    It's possible I might have lost a bracket or something.

    In any case, JavaPF gave me a page to look at and I'm going to.

    I tried the code JavaPF suggested but it's not working.

    In fact, it's not displaying anything at all now.

    What I'm trying to do is use a Timer on the FountainAnimator class to keep repainting the JLabel in the ShowMouseLocation class to the position of the mouse inside the FountainAnimator class.

    This was because I'm trying to make an analog clock and it'd help to figure out the positions instead of having to spend a long time guessing.

    To ensure that the code will compile, I've given the entire program that I've had.

    However, I'm convinced that the problem is within either the ShowMouseLocation class and/or is some glitch with the Timer in the FountainAnimator class or something else like calling the wrong repaint() somewhere inside the ShowMouseLocation class or something.

    The problem wouldn't be caused by my setting autoScrolls to true for the FountainAnimator object, would it?

    I don't know what autoscrolls are but what I had been looking for when I wrote that part was to get the thing to resize withiout adding any new components to it, but I figured out that revalidate() was what I was looking for for that problem.

    Is this possibly a contentPane issue for ShowMouseLocation as I didn't ever call setContentPane() ?

    The ClockListener and stuff like that are only there because in the earlier, smaller code, I must have either forgotten a bracket and/or not erased a variable that refereed to one of those removed classes.

    Also, the MouseListeners in FountainAnimator no longer are needed. They're not the problem, I think, either.

    Also, the methods like drawLake() and such are not important to the problem being discussed. They are only there to ensure that the code will compile.

    The most likely spots that the problem is in are:

     public class ShowMouseLocation extends JFrame implements ActionListener
          {
     
     
             private JLabel positions;
             private String str;
             public ShowMouseLocation()
             {
     
     
                positions = new JLabel();
                add(positions);
     
             }
     
     
             public void actionPerformed(ActionEvent e)
             {
     
                xLocation = MouseInfo.getPointerInfo().getLocation().x;
                yLocation = MouseInfo.getPointerInfo().getLocation().y;
     
     
     
                str = "<br>"+xLocation + "</br>" + "<br>" + yLocation + "</br>";

                repaint();
     
             }
     
             public void paint(Graphics g)

                positions.setText(str);
     
     
     
             }
          }

    and

     public class FountainAnimator extends JPanel implements ActionListener, MouseListener 
          {
             private ShowMouseLocation sml;
             private Timer aTimer;
     
     
             public FountainAnimator()
             {
                super(new BorderLayout());
                setBackground(Color.GREEN);
                sml = new ShowMouseLocation();
                sml.setVisible(true);
     
                aTimer = new Timer(0,sml);
                aTimer.setDelay(100);
                System.out.println(xLocation);
                System.out.println(yLocation);
     
     
     
             }

    Hmmmmm...also thought of something.

    It appears that most of my other Timers are inside the PaintDemo1 constructor and the Timer I'm using for the MouseLocation thingy is not. Could that be the problem?

    Also, I don't think I'm setting it to track the mouse position of the FountainAnimator thing like I wanted the code to but don't know how to do that exactly.

    it's not working.
    Please explain.
    Try debugging the code by adding printlns to it to show the execution flow.

    You need to understand your program's logic and the problem you are having so that you can write a small executable program that we can compile and test with.

    Can you work on one problem at a time?

    I printed out the values already and they indicate that the mouse is always at 0.0, 0.0.

    Here, I've made the program shorter to get at the problem quicker:

    I've told you about this before and you seem to have ignored it.
    When I execute your program all I get is a titlebar, no window???
    Please fix it and post working code next time.

    It is working.

    It just starts out minimized.

    I don't know what's causing that either.

    Can't fix that.

    Try enlarging it.

    Perhaps it's because I'm using JGrasp to compile this or something like that.

    I can't figure out how to start it out maximized.

    @javapenguin - I still don't see where you're adding a MouseListener to a component. Please explain how you think the MouseListener action methods are going to be called - or is the MouseListener no longer an issue anymore, you seem to have removed it from your latest post.

    I'm no longer sure what you're asking for help with...

    I can't believe that you have over 1000 posts and ignore something as simple as starting the app window with a size.

    Plus you don't exit the JVM when you close the window so it leaves orphan java programs running.

    Please fix these two problems before posting any more code.

    I don't need a MouseListener apparently.

    MouseInfo class should work instead. However, Norm can't seem to get it to maximize the window.

    I don't know what's causing that either.

    I can maximize mine, though mine always starts out minimized.

    All I wanted was to track the Mouse Position inside the FountainAnimator class and get it to show that position on the JFrame in the ShowMouseLocation class.

    I thought that I needed a MouseListener earlier but now have found that I don't. However, the new code that should be working isn't working.

    The MouseInfo code isn't working that is.

    I was able to set a minimum size.

    If there's like a setMaximized(true) option, I can't figure out what it is.

    sml = new ShowMouseLocation();
    sml.setVisible(true);

    aTimer = new Timer(0,sml);
    aTimer.setDelay(100);


    Should be working correctly, but it probably isn't.

    Should be, but it probably isn't.
    Why not read the API doc or the tutorial to see how to use a Timer?

    Wait a minute.....



    I never started the Timer, did I?

    Yep, that kinda would explain a lot.

    However, why isn't my JLabel breaking into lines apart with the <br> code?

    Now the Mouse Locator is working!

    But why is the <br> still literally there instead of line breaking?

    Ok, but how do I get it to show the position relative to the Mouse location on FountainAnimator?

    So far it's just showing the location relative to the screen.

    Ok, the Component method of

    getMousePostion().get(X) is out too apparently. It's just causing a Null Pointer Exception.

    Should I try using a MouseEvent object or will that not work either?

    When you get errors, please copy and paste the full text of the error message here. Also post the code that generated the error.

             locations in the FountainAnimator object animator, or any FountainAnimator object perhaps for that matter(at least animator at the very least).
             Anyway, I had hoped that it would show this location in the other JFrame.  However, the JFrame has a hard time staying open at the same time as my main JFrame.  If I minimize them both to really small size, then I can show both at same time, otherwise clicking on one of the JFrames makes the other automatically minimize.  But that's not the real issue here, though it certainly is annoying.  Actually, what I had hoped for was to originally show
             the mouse pointer in a JPanel thing that would be placed below the FountainAnimator object and then combine thse two into a single panel that shows both or something.  Kinda like how in JGrasp and other compilers, it shows the position where the key is ready to type, the vertical bar thingy that shows where you're about to type, anyway, it shows its position below in a smaller JPanel or whatever.  Anyway, I tried that and it wouldn't work quite well as one of the panels appeared too small or  something.  As it is, I am trying it this way unless you could show me how to use the layouts to attach a small JPanel thing that only has the JLabel on it to the bottom of the FountainAnimator object or something like that.  */

    animator.getMousePosition().getX() is returning null.

    I'm trying to get the position of the mouse relative to the pixel position of the mouse inside the animator object.

    The FountainAnimator object.

    BTW, making a MouseEvent object and trying that route always yielded the Point (0,0).
