Intermittent MousePressed Events
I am having trouble with mouse pressed events. I have a JFrame with 2 images in JPanels, with a separate JComponent sindow that will display one or the other image with a delay. It flickers between the 2 images using a thread. The JPanel responds to MousePressed events with the flickering turned off. When it is turned on the mouse pressed events are intermittent, I placed a print statement in the MousePressed method and I have to keep clicking the mouse to get it to work.
Has anyone seen MousePressed problems with threads before?
Thanks, Greg
I am afraid it was my own bug :(
I had reimplemented processMouseEvent() in my subclass of JTextPane to consume mouse events in the margin area if the click count was >1 thinking this applied only to mouse clicks and not mouse pressed.
Still had the issue of the JTextPane itself being a mouse listener to do text selection (word for double click, line for triple click). So what I did was : if the click was in the margin area I would determine if it was the type i needed (pressed) and pass the event to my listener and otherwise not pass it to the super method. So all solved now. :)
I prepared a small test - obstensibly to post - but that showed it was indeed my bug and after more searching found the answer. It is quite a big project with parts written many years ago. Even so, a bit red faced now ...

Can't get mousePressed event to work
Hi all!
I have class, that extends DefaultTableModel. I can not make that when end user click on specifc cell, to create new class.
Code looks like this:
public class ContactList extends DefaultTableModel implements MouseListener {
public void mousePressed(MouseEvent mouseEvent) {
ContactUpdate conUpd = new ContactUpdate ();
}Can you help me with this? Thank you in advance!In the future, Swing related questions should be posted in the Swing forum.
Attach the MouseListener to the JTable, not its model. -
Changing times of an intermittently recurring event
Let me clarify that.
So I have my work dates/times in iCal.
I work a varied schedule (shift work in a hospital) as in varied days on a given week.
I am now changing my hours worked from a 3am start to a 7pm start.
Is there a way to change all my current 3am work entries to this new time?
Many thanks!Steven,
The only way that I know of is to drag the events to the new time using the week view.

panel.addMouseListener(new MouseAdapter(){

System.out.println("Mouse Pressed!");

popup.show(e.getComponent(), e.getX(), e.getY());
public void mouseReleased(MouseEvent e){
System.out.println("Mouse Released!");
if(e.isPopupTrigger())
popup.show(e.getComponent(), e.getX(), e.getY());
frame.add(panel);
frame.setVisible(true);
}When I right click, the popup menu shows up and prints:
Mouse Pressed!
Mouse Released!
Then I click on another position, it will print:
Mouse Pressed!
Mouse Released!
The problem is when I set the LookAndFeel to SystemLookAndFeel (which is Windows XP), it only prints:
Mouse Released!
after the pop up menu shows up.
I wonder what happened to the Mouse Pressed Event?Late to the party, but I'd like to add that I came across this same problem when we recently upgraded from 1.6_02 to 1.6_11. I have a JTable where a right-click produces a JPopupMenu, but a double right-click is a shortcut to one of the popup menu functions. Popup shows up fine on the single-click in both, but the double-click function didn't work in the later version.
As hinted in this thread, it happens when you are reacting to the mousePressed event and you've install the System L&F (at least on Windows XP). I printed out PopupMenu.consumeEventOnClose after setting the L&F, and it reported true. So all I did was override that property to false after setting the L&F, and everything was back to normal.
Not sure why that changed between those two updates. There were bug fixes 6539458 in u4 and 6217905 in u10 that are both related to JPopupMenu, so maybe one of those accounts for the difference. Hopefully I'm not breaking something by overriding the property. -
How to enqueue custom AWT event?
hi,
in my applet I need to use custom AWT events. I subclass them from java.awt.AWTEvent and set their id to higher as AWTEvent.RESERVED_ID_MAX - as recomended in documentation.
But how to enqueue such event? A tried to use following approach:
getToolkit().getSystemEventQueue().postEvent( myEvent );
and it works fine - but only in browsers usings Sun's VM implementation. In browsers using Microsoft's VM I'm getting following exception:
com.ms.security.SecurityExceptionEx[matlu/client/ClientConnection.enQueue]: Event queue access denied.
So the question is: is there any other way to enqueue custom event, which will keep Microsoft's security manager happy?
thak you very much
Lubo MateckaI know it must be visible... (But it doesnt have to be bigger than 1 pixel...)
The code I posted is just to illustrate the idea.
If you need to post multiple events you just replace the AWTEvent member with a LinkedList (or some similar FIFO).
Then in postEvent you do theLinkedList.addFirst(yourEvent)
And in paint() you do AWTEvent ev = (AWTEvent)theLinkedList.removeLast();
process ev.
if(theLinkedList.size() > 0)
repaint();Yes. I have run into the same problem, and I did not use the repaint- trick...
My applet communicates with the server in a separate thread. When a response receives the communication thread should post an event to the AWT- thread to get the response processed.
My solution here is to process the thread in the communicator- thread. This is a bad solution because it might create multithreading bugs.... but it has proven to work ok in practice.
Another example is like this. The use presses the mouse at Component B so that:
1 Component A gets a focusLost event.
2 Component B gets a mousePressed.
3 I want to do something in component A that should be done after component B has processed the mousePressed event. This can be solved without using events. You just have to write some more code (You are already in the right thread). -
Hello,
Is there a way to let a JTable listen to a double click event? I know that you can easily get the selection by a 1 click, but now I want that when there is double clicked an action happens (in this case a popup with a question).
For the double click event, I think you best could use the mousePressed event together with the int getClickCount(). Can you put that mousePressedEvent on the ListSelectListener and than count the amount of clicks and if 2 or more you fire an action (popup)?
GrtzUsing MouseAdapter is a nicety, because you OVERRIDE only the methods you need. In this case mouseClicked(MouseEvent mouseEvent). You did not have to implement all the methods defined in the http://java.sun.com/j2se/1.5.0/docs/api/java/awt/event/MouseListener.html interface.
The @override annotation should be there because you have just overridden a method already defined in a super class. The main reason is for compiler checking. It basically marks the method, then if the compiler sees the method does not override anything it will complain (For example someone changed the super classes methods name and you did not realise, in this case the compiler will fail because it no longer overrides anything, and you know you need to fix it...i.e. rename your method to match).
So it's not imperative you add the annotation but it can save you some anguish.... especially if you deal with alot of third party library's that do not maintain backwards compatibility.
http://java.sun.com/docs/books/tutorial/java/javaOO/annotations.html
"@Overridethe @Override annotation informs the compiler that the element is meant to override an element declared in a superclass "

Hello,
Situation:
in my application, I open up a new window (singelton). There I have a "close"-Button with a mouse_over effect. When I close the window and reopen it with this button, the button is still selected, because no mouse_exited has taken place.
Question:
How can I simulate the Mouse event or set back the status of the button?
Thanks,
WolfgangWhat you could do is add a mouse listener to your component, and when you detect a mousePressed event, set an internal flag like "buttonDown" or something so that your componentResized method knows when to ignore that event. Maybe something like this:
myComponent.addMouseListener(new MouseAdapter()
public void mousePressed(MouseEvent e)
mouseButtonDown = true;
public void mouseReleased(MouseEvent e)
mouseButtonDown = false;
myComponent.addComponentListener(new ComponentAdapter()
public void componentResized(ComponentEvent e)
if (mouseButtonDown)
return;
// now do whatever -
I have found a horrid bug in IBM's J9 CDC implementation.
The way they have implemented popup trigger is by placing it in the mousePressed event. Since the trigger on PocketPC is to hold the pen on the screen for a "while", this means the mousePressed event is not delivered straight away.
The result of this is that the application does not know when the pen hits the screen, but only at some point later! this makes all kinds of stuff impossible; from signature captures to drawing apps, to custom on screen keyboards... loads of stuff.
It is sounding like IBM does not regard this as a bug but a feature of the platform. I do not agree with this at all, as it is just poorly implemented. If the trigger was placed in the mouseRelaesed event the mousePressed event could be delivered striaght away, and the trigger could be detected from the difference in time beteeen the press and release (providing no or little mouse movement ocurred in the elaped time). This is not a tricky fix by any means.
Anyway, to my point;
Surely the certification for whether a CDC platform is compliant or not should cover obvious things like making sure events happened when they are meant to. After all, mousePressed() is called that for a very good reason! maybe mousePressedSomeTimeAgo() would be better ;)Hi,
I tried both Socket and Connector.
For Socket take:
try {
Socket sock = new Socket("61.31.254.13", 4004);
OutputStream out = sock.getOutputStream();
out.write("hello".getBytes());
// start another reader thread...
} catch (Exception ex) {
ex.printStackTrace();
}Exceptions look like:
java.net.ConnectException:61.31.254.13/61.31.254.13:4004 - Operation failed: 10065 (FormatMessage failed: 317)
at java.net.PlainSocketImpl.connect(Unkown Source)
at java.net.Socket.startupSocket(Unkown Source)
at java.net.Socket.<init>(Unkown Source)
....For Connector take:
try {
StreamConnection c = (StreamConnection) Connector.open("socket://61.31.254.13:4004");
OutputStream out = c.openOutputStream();
out.write("hello".getBytes());
// start another reader thread...
} catch (Exception ex) {
ex.printStackTrace();
}Exceptions:
javax.microedition.io.ConnectionNotFoundException: Cound not establish connection: (61.31.254.13) 61.31.254.13:4004 - Operation failed: 10065 (FormatMessage failed: 317)

JC.L -
Is there any way to get information about the mouse (e.g., which buttons if any are pressed) without an MouseEvent?
I'm listening for Component events, and in the componentResized method I'd like to know if the mouse button is down so I can ignore the resizing events until the user is done resizing. There's no "isAdjusting" option like JSlider has.
Thanks.
-JWhat you could do is add a mouse listener to your component, and when you detect a mousePressed event, set an internal flag like "buttonDown" or something so that your componentResized method knows when to ignore that event. Maybe something like this:
myComponent.addMouseListener(new MouseAdapter()
public void mousePressed(MouseEvent e)
mouseButtonDown = true;
public void mouseReleased(MouseEvent e)
mouseButtonDown = false;
myComponent.addComponentListener(new ComponentAdapter()
public void componentResized(ComponentEvent e)
if (mouseButtonDown)
return;

JPanel key events blocked by JToolBar?
I have a JPanel that I'm drawing on, and the frame containing the panel also holds a JToolBar. The JPanel doesn't catch any KeyEvents, which I really would like to monitor.
I have overridden isFocusable() as suggested in another thread like so:
public boolean isFocusable()
return true;
}My JPanel still doesn't catch KeyEvents, unless I get rid of the JToolBar. It seems that the controls in the toolbar don't pass the focus on to the panel. How do I change this behavior, without removing the toolbar?Found the answer elsewhere.
I now add a "requestFocus()" call in my mousePressed event handler, and the JPanel catches the key events again. -

xfoI'm (being lazy and) using the older RT app posted on your last thread. I removed the
TimeNow timer from the RT class and used System.currentTimeMillis (as you requested) to
determine the elapsed time during the animation (see "startTest", "stop" and
"movingObject" methods). Also changed the DecimalFormat to NumberFormat and set the
"maximumFractionDigits" to "2" so it will truncate the fraction to two digits (more simple
than before). Made arrangements for the ShapeMovingPanel class to update the
"timerJTextField" during the animation (RT.updateTime method).
The MouseMotionListener is causing the animation to appear jerky and uneven. The
"mouseMoved" method is very busy while the mouse is moving. You might consider recording
the "mousePressed" events instead of the "mouseMoved" events, ie, the events where the user
is attempting to click inside the moving shape. It would allow the app to be more
responsive and might eliminate the uneven motion of the animating shape.

Hello.
i�m using mouse events to run some events in my apps..
but the problem is that this only occurs once in a while, and it should happen every time i give a double click...
i�m using the mouseclicked event...is i clicked twice (getmouseclick == 2), then an event is done...but this doesn�t occur always....
can this be caused because i�m clicking too fast that tha app isn�t catching the clicks?? should i use the mousepressed event??
thanxyou can not move the mouse when you click. the mouse has to stay in the same spot when you click and release.

Chess Piece display problem in applet
Hi,
I'm writing a chess game applet which will be played between to players over the internet. I'm currently working on the applet side at the moment and will develop the server side once I have completed the applet. I'm currently having problems displaying the actual chess pieces on the board at the moment. One of my design decisions was to make a Board class which extends a JPanel. I have painted the actual chess board squares within the Board JPanel. I then propose to draw the pieces on top of these squares (good design decsion? Can anyone suggest another way. I was thinking of having the images as a separate layer which will sit on top of the squares but wasn't sure how to implement it). The chess pieces are contained in a gif strip www.dur.ac.uk/j.d.p.murphy called ChessPieces02.gif . The problem I am having is to display several pieces at the same time. I lloked at a Java tutorial which suggested using g.clipRect() method to display a defined section of the strip (i.e. a single piece of a certain length). Below is the Board class that I am using.

// Holds location of the mousePressed event
Point point = null;
// Size of a square square on the board
int square_size = 40;
// Mediatracker to monitor the loading of the images
MediaTracker tracker;
Image image;
void init() {
tracker = new MediaTracker(this);
image = Toolkit.getDefaultToolkit().getImage("ChessPieces02.gif");
tracker.addImage(image, 0);
try {
//Start downloading the images. Wait until they're loaded.
tracker.waitForAll();
} catch (InterruptedException e) {
e.printStackTrace();
throw new Error("error");
if (tracker.isErrorAny()) {
throw new Error("Could not load image");
addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
if (point == null)
point = new Point(0, 0);
int x = e.getX();
int y = e.getY();
System.out.println("X co-ord: " + x + " Y co-ord: " + y);
// Floor the x and y values to the nearest unit of 25
x = x - x % square_size;
y = y - y % square_size;
point.setLocation(x, y);
repaint();
System.out.println(point);
public void paintComponent(Graphics g) {
super.paintComponent(g); //paint background
System.out.println("Chess Board Paint");
// Loop to produce the black and white squares to represent the board
for(int jj = 0; jj < 8; jj ++){
for(int ii = 0; ii < 8; ii++){

What code do i need to add more pieces to the board? I plan to make a ChessPiece array (8x8) which will holld all the chess pieces on the board. Should I hold this array in the board class to make drawing the pieces easier? Any other tips for game development would also be most welcome.
Thankscross post, I think.

Clicking on a column without disturbing the existing selection
Hello good people,
I am still getting used to Swing and my question may be really silly. Thanks in advance for helping me out!
I have a JTable in which one of the columns has checkboxes. Using Ctrl+select, one can select multiple rows. Clicking without ctrl, unselects the previous selection. This is all good and default behavior. However, I would like to be able to click on one of the checkboxes in one of the selected rows and not disturb the selection. My target is to enable/disable the checkboxes of all the selected rows.
Basically, my question is: How do I not disturb the selection if a user clicks in one of the already selected rows and the checkbox column. In other words, if I clicked on the cell (r, c) where row r is already selected and column 'c' is the checkbox column, I would like to retain the selection.
Thanks,what I meant was if you click on the flag cell of one of the selected rows, all the rows (emails) will be flaggedIn my version of Outlook (which is really old) only the row you click on will be flagged and the other rows are deselected.
But you could try adding a MouseListener to the table. When a mousePressed event is received you could save all the selected rows. You would also add a TableModelListener to the TableModel. Whenever the flag field is selected you could then loop through all the saved selected row and set the flag. You would want to remove the TableModelListener before you start the loop to prevent multiple table model events from being generated. Then when the loop finishes you would need to add the listener back to the model.
However, this is not a very good solution since it depends on the mousePressed event firing before the ListSelectionModel is updated.
